Chemotherapy of breast cancer: current views and results.

The paper critically reviews major accomplishments achieved with the use of chemotherapy in the treatment of various stages of breast cancer. In spite of innumerable clinical trials, there is no evidence that in advanced breast cancer the addition of more drugs, either in concomitant, sequential or alternating fashion, to known effective combinations, was able to significantly improve the incidence and the magnitude of objective response or its median duration or survival. The addition of endocrine therapy to chemotherapy has failed so far to improve the most important end-point, i.e. total survival. Second-line chemotherapy is only moderately effective for a fairly short period of time. Thus, in women with advanced breast cancer excessive tumor cell burden and permanent drug resistance remain the major obstacles to obtaining complete remission and long-term disease free survival. In the adjuvant setting, the initial trials with combination chemotherapy have achieved consistent results, particularly in women with minimal axillary node involvement. Unless a woman has undergone a surgical breast-saving procedure, postoperative radiotherapy does not appear to play an important therapeutic role, either with or without concomitant or sequential chemotherapy. Present results would suggest that in advanced breast cancer little progress can be expected in the near future. Therefore, medical oncologists should focus on the correct application of established drug regimens, using a sequential flow of hormonal manipulations and cytotoxic chemotherapy. In high-risk groups, full dose adjuvant polydrug therapy given for a relatively short period of time appears to be at present the only means able to significantly decrease the failure rate following local regional treatment. Present consistent achievements, which appear devoid of important delay morbidity (e.g. cancerogenesis, chronic organ damage) will require further clinical research to identify more effective and less toxic treatments.

Hancock II porcine bioprosthesis: excellent durability at intermediate-term follow-up.

OBJECTIVES: This study aimed to assess the clinical performance and durability of a new generation of porcine valve, the Hancock II bioprosthesis, at intermediate-term follow-up. BACKGROUND: Standard porcine bioprostheses undergo progressive structural deterioration, mainly due to cusp and commissural calcification, affecting durability and requiring reoperation. The Hancock II bioprosthesis, which is currently undergoing clinical investigation, is made from a porcine aortic valve treated with a calcium-retarding agent (sodium dodecyl sulfate [T6]), which should delay onset of calcification and increase durability. METHODS: From May 1983 to December 1992, we used the Hancock II bioprothesis in aortic (59 patients), mitral (101 patients) and mitral-aortic (25 patients), valve replacement procedures. Postoperative follow-up ranged from 0.1 to 8.7 years (mean [+/- SD] 4.5 +/- 2.6 years) and was 100% complete. Freedom from major postoperative events was calculated at 7 years for patients with aortic valve replacement and at 8 years for those with mitral and mitral-aortic valve replacement. RESULTS: The actuarial survival rate was 48 +/- 10%, 76 +/- 3% and 63 +/- 6%; freedom from valve-related mortality was 91 +/- 4%, 94 +/- 2% and 89 +/- 6%; freedom from thromboembolism was 80 +/- 11%, 90 +/- 2% and 79 +/- 7%; and freedom from reoperation was 100%, 97 +/- 1% and 89 +/- 6% after aortic, mitral and mitral-aortic valve replacement, respectively. No structural valve deterioration occurred. CONCLUSIONS: At intermediate-term follow-up the Hancock II bioprosthesis showed excellent durability in all positions. However, the effectiveness of anticalcification treatment must be assessed with longer follow-up studies.

Laparoscopic esophageal myotomy for achalasia: factors affecting functional results.

BACKGROUND: We reviewed our experience and analyzed factors affecting functional results after laparoscopic esophageal myotomy (LEM) for achalasia. METHODS: From January 1996 through October 2003, the records of 211 patients (110 men and 101 women) who had LEM for achalasia were reviewed, and factors affecting morbidity and functional results were analyzed. RESULTS: Median age was 47 years (range, 12 to 85). One hundred and twenty-five patients (59%) had prior esophageal dilatation and/or botulinum toxin injection and 19 (9%) had a prior myotomy. A partial fundoplication was performed in 198 patients (94%); posterior in 135 and anterior in 63. Median operative time was 208 minutes (range, 90 to 527). Intraoperative complications occurred in 37 patients (17.5%), and included mucosal perforation in 32, pneumothorax in 2, and retained needle, splenic capsular tear, and gastric short vessel bleeding in 1 each. Five patients (2%) required conversion to an open procedure. Postoperative complications occurred in 17 patients (8%) including 2 patients who required reoperation for leak. There were no perioperative deaths. Median hospitalization was 3 days (range, 1 to 48). Follow-up was complete in 167 patients (79%) and ranged from 1 to 70.5 months (median, 5.3). Functional results were classified as excellent in 105 patients (63%), good in 43 (26 %), and fair or poor in 19 (11%). Previous esophageal surgery for achalasia adversely affected functional results (p = 0.0139). Preoperative bougie dilatation (p = 0.9851), pneumatic dilatation (p = 0.8548), botulinum toxin injection (p = 0.1724), and the type of fundoplication (p = 0.5904) did not affect functional results. Preoperative bougie dilatation (p = 0.441), pneumatic dilatation (p = 0.1060), and botulinum toxin injection (p = 0.3938) did not affect the incidence of intraoperative perforation. As experience is gained, the incidence of intraoperative complications has decreased significantly (p = 0.0075). CONCLUSIONS: Laparoscopic myotomy for achalasia is safe and effective in the majority of patients. The incidence of intraoperative complications decreases as experience is gained. Preoperative endoscopic treatment does not preclude successful surgical outcome. Excellent or good functional results are achieved in the majority of patients although previous surgical treatment adversely affects functional results.

Surgical management of bronchiectasis in childhood.

OBJECTIVE: Though there is a gradual decrease in the prevalence of bronchiectasis, it is still a cause of mortality and morbidity among children in developing countries such as Turkey. We reviewed the morbidity and mortality rates and the outcome of surgical treatment for childhood bronchiectasis. PATIENTS AND METHODS: Age, sex, etiological factors, symptoms, radiological examinations, surgical procedures, postoperative morbidity and mortality in patients aged 16 years and younger, operated for bronchiectasis between January 1991 and April 2006 in the Thoracic Surgery Clinic of Atatürk Training and Research Hospital for Chest Disease and Chest Surgery were reviewed retrospectively. RESULTS: Between January 1991 and April 2006, 176 cases aged 16 and younger were operated for bronchiectasis. There were 95 females (54%) and 81 males (46%), with a mean age of 12.3 years (range: 3.4-16 years). The most common cause of bronchiectasis was lung infection (n: 87, 49.4%). Main symptoms were coughing (n: 167, 94.9%), sputum (n: 139, 79%), hemoptysis (n: 78, 44.3%), and fever (n: 77, 43.7%). Mean duration of the symptoms in patients who were operated was 3.8 years (range: 0-7.6 years). Cases underwent a total of 201 operations: 19 cases had bilateral surgical resection and 6 cases had completion pneumonectomy. Majority of cases had complete resection (n: 165, 93.75%) while only 11 cases (6.25%) had incomplete resection. Mean duration of hospitalization was 8.9 days (range: 5-39 days). The outcome, based on the responses of patients postoperatively, was 'perfect' in 129 cases (73.3%), 'improved' in 41 cases (23.3%), and 'no changes' in 6 cases (3.4%). The mean follow-up after surgery was 4.3 years (range: 14 months to 7.2 years), mortality was 0% and morbidity was 13% (n: 23). CONCLUSION: With acceptable mortality and morbidity rates and high chance of cure after complete resection, surgical treatment is a successful and reliable method of treatment in childhood bronchiectasis that yields marked improvement in the quality of life.

Cataract surgery without preoperative eyedrops.

We present a technique that uses intracameral lidocaine to induce pupil dilation without using preoperative mydriatic eyedrops. After 1 or 2 drops of topical lidocaine hydrochloride 1% (Xylocaine-MPF 1%) are applied to the ocular surface, a 1.0 mm side-port incision is created through which Xylocaine-MPF 1% is injected into the anterior chamber. The lidocaine paralyzes the pupil sphincter, and adequate mydriasis occurs within 90 seconds. Epinephrine (0.3 cc of 1:1000) is added to the irrigation fluid comprising balanced salt solution (BSS), and standard phacoemulsification with intraocular lens implantation is performed. Pupil dilation is maintained or increased during the procedure. Postoperatively, the pupil returns more quickly to normal size and reaction. Using lidocaine for mydriasis instead of standard dilating drops eliminates the cardiac risk of topical sympathetic agents, decreases the time patients wait in the holding area before surgery, reduces the risk of superficial punctate keratopathy, and provides faster recovery of normal pupil function.

Fixed, dilated pupil after phakic intraocular lens implantation.

A 26-year-old man with degenerative high myopia had bilateral anterior chamber phakic intraocular lens (IOL) implantation under general anesthesia. The preoperative slitlamp examination was normal. No mydriatic drops were used before, during, or after the procedure. Postoperatively, the intraocular pressure (IOP) in the right globe increased to 60 mm Hg. After the IOP was controlled, the pupil became fixed and dilated. Iris fluorescein angiography was obtained and delayed filling of the iris capillary plexus with large areas of no perfusion was observed in the right eye. Based on these findings, a diagnosis of Urrets-Zavalia syndrome was made. To our knowledge, this is the first report of Urrets-Zavalia syndrome after phakic IOL implantation.

Predicting the outcome of shunt surgery in normal pressure hydrocephalus.

We studied retrospectively the effectiveness of the repeated lumbar CSF tap test (RTT), lumbar external CSF drainage (LED) and radioisotope cisternography (RIC) in predicting the outcome of shunt surgery, as well as the diagnostic and prognostic value of periventricular hyperintensity (PVH) and of the classic clinical triad in normal pressure hydrocephalus. Two hundred and seventy patients were referred to the Departments of Neurosurgery, in Nancy, France and in Istanbul, Turkey. The decision to perform surgery was based on the clinical presentation (all patients had at least two symptoms of the classic clinical triad), neuroimaging examinations and the results of the RTT (taps were performed on three consecutive days and at each tap a minimum of 30 to 40 cc of CSF was removed), the LED (drainage was performed for 3 days and the volume of CSF drained daily was a minimum of 150 to 250 cc) or the RIC. After all shunt procedures, postoperative assessments verified improvements in 88% of the RTT group, 91% of the LED group and 66% of the RIC group. Gait disturbance had improved in 90% at the end of the second and twelfth month follow-up. Cognitive dysfunction had improved in 79% at the second and in 77% at the twelfth month follow-up. Urinary incontinence had improved in 66% at the second and in 62% at the twelfth month follow-up. From the surgical point of view, the greatest difficulty is not to make the diagnosis, but rather to identify the appropriate patients to operate on. The decision to perform shunt surgery should be based on strict clinical findings associated with CT and MRI criteria and especially with positive RTT or LED test results.

Longitudinal pancreaticojejunostomy and selective biliary diversion for chronic pancreatitis in children.

BACKGROUND: Chronic pancreatitis requiring surgery is rare in children. We review our experience in treating pediatric chronic pancreatitis with longitudinal pancreaticojejunostomy (LPJ). METHODS: Records of children with chronic pancreatitis treated with LPJ between 1997 and 2003 were reviewed. Demographic data, associated conditions, endoscopic interventions, operative procedures, postoperative complications, length and costs of hospitalization, and long-term outcome were recorded. RESULTS: Four patients (one girl), 3 to 16 years old, underwent LPJ. Associated conditions included bile duct obstruction (2), single (1) or multiple (1) pancreatic duct strictures, recurrent familial pancreatitis (1), pseudocyst (1), Down's syndrome (1), and duodenal web (1). Preoperative endoscopic stenting was performed in two patients. All were on restricted diets, one on parenteral nutrition. Pre-LPJ, each child had 3 to 6 admissions for pancreatitis with mean total cost of 39,000 dollars, excluding diet charges. At surgery, two patients required biliary diversion for persistent biliary obstruction in addition to LPJ. Postoperatively, no patient developed fistulas or anastomotic leaks. There were no deaths. The median length of hospitalization post-LPJ was 8 days with mean cost of US37,000 dollars. All patients resumed a normal diet post-LPJ. There were no recurrences of pancreatitis with follow-ups between 2 and 6 years. CONCLUSION: Longitudinal pancreaticojejunostomy is safe and cost-effective for treating pediatric chronic pancreatitis. It has minimal complications and frees patients from pancreatitis-related hospitalizations.

Anastomotic fibrous ring as cause of stricture recurrence after bulbar onlay graft urethroplasty.

PURPOSE: We retrospectively reviewed patterns of failure after bulbar substitution urethroplasty. In particular we investigated the prevalence and location of anastomotic fibrous ring strictures occurring at the apical anastomoses between the graft and urethral plate after 3 types of onlay graft techniques. MATERIALS AND METHODS: We reviewed the records of 107 patients who underwent bulbar urethroplasty between 1994 and 2004. Mean patient age was 44 years. Patients with lichen sclerosus, failed hypospadias repair or urethroplasty and panurethral strictures were excluded. A total of 45 patients underwent dorsal onlay skin graft urethroplasty, 50 underwent buccal mucosa onlay graft urethroplasty and 12 underwent augmented end-to-end urethroplasty. The clinical outcome was considered a success or failure at the time that any postoperative procedure was needed, including dilation. Mean followup was 74 months (range 12 to 130). RESULTS: Of 107 cases 85 (80%) were successful and 22 (20%) failed. Failure in 12 patients (11%) involved the whole grafted area and in 10 (9%) it involved the anastomotic site, which was distal and proximal in 5 each. Urethrography, urethral ultrasound and urethroscopy were fundamental for determining the difference between full-length and focal extension of re-stricture. Failures were treated with multistage urethroplasty in 12 cases, urethrotomy in 7 and 1-stage urethroplasty in 3. Of the patients 16 had a satisfactory final outcome and 6 underwent definitive perineal urinary diversion. CONCLUSIONS: The prevalence and location of anastomotic ring strictures after bulbar urethroplasty were uniformly distributed in after 3 surgical techniques using skin or buccal mucosa. Further studies are necessary to clarify the etiology of these fibrous ring strictures.

The influence of aortic cuffs and iliac limb extensions on the outcome of endovascular abdominal aortic aneurysm repair.

BACKGROUND: In a proportion of patients with an endovascular abdominal aortic aneurysm repair (EVAR), aortic cuffs or iliac graft limb extensions are required to enhance sealing or to fix the position of the device. This requirement arises when these goals are not primarily obtained with the basic stent-graft configuration. The aim of this study was to assess the influence of the use of endograft extensions during the primary EVAR procedure on the short- and long-term outcome. METHODS: The study was based on the data of the EUROSTAR registry. Patient and anatomic characteristics, data regarding the procedure, postoperative complications, and the mortality of patients undergoing EVAR were retrieved from the database. Patients were divided into three groups: (1) no extensions, (2) proximal aortic cuffs, and (3) iliac limb extensions. Logistic regression and Cox proportional hazards models were used to compare significant influences of the use of cuffs or extensions on different outcomes relative to control patients, adjusted for patient and anatomic factors. RESULTS: The overall cohort comprised 6668 patients: 4932 (74.0%) without extensions, 259 (3.9%) with an aortic cuff, and 1477 (22.2%) with an iliac endograft extension. Both the 30-day (2.3%-3.9%) and the all-cause mortality rates (23%-27% at 4 years) were similar in the three study groups. The use of proximal cuffs or iliac extensions did not have an effect on the incidence of endoleaks of any type (24%-32% at 4 years). The incidences of device kinking (P = .0344) and secondary transfemoral interventions (P = .0053) during follow-up were increased in patients in whom iliac limb extensions were used. In patients with aortic cuffs, no significant associations with altered outcome were observed. CONCLUSIONS: The use of iliac graft limb extensions at EVAR was associated with a higher incidence of kinking and secondary transfemoral interventions, whereas proximal aortic cuffs did not influence outcome.

Airway complications from topical mitomycin C.

OBJECTIVE: Topical application of mitomycin C appears to be a useful adjunct in reducing cicatricial scarring of the airways. Human and animal studies have demonstrated the efficacy and safety of mitomycin C topically in the treatment of airway stenosis at concentrations ranging from 0.4 mg/mL to 10 mg/mL. Although no reports of mitomycin C toxicity have been reported in the otolaryngology literature, the ophthalmologic literature has documented serious, vision-threatening complications resulting from the use of topical mitomycin C. The purpose of this study is to report complications related to mitomycin C use in the treatment of glottic and subglottic stenosis. Risk factors associated with these complications are identified. STUDY DESIGN AND SETTING: A retrospective chart review of all patients treated by the senior author for laryngotracheal stenosis with endoscopic CO(2) laser incisions/dilation and adjuvant topical mitomycin C was performed to determine the incidence of complications. Variables studied included patient age and gender, location and severity of stenosis, medical comorbidities, length of procedure, postoperative instrumentation of the airway, and mitomycin C concentration. RESULTS: Eighty-five cases of adjuvant topical mitomycin C use after CO(2) laser endoscopic treatment and dilation for upper airway stenosis were identified in a total of 44 patients. Complications that were believed to be caused by the local toxicity of mitomycin C occurred in 4 cases out of 85 (or 4.7%), manifested by accumulation of fibrinous debris at the operative site, resulting in partial airway obstruction and the need for emergent airway intervention. CONCLUSIONS: Caution should be exercised when topical mitomycin C is used in the treatment of airway stenosis.

Pain control: opioid dosing, population kinetics and side-effects.

Neonates undergoing invasive procedures, postoperative pain or ventilatory support commonly receive opioids for treating pain and stress. Randomized clinical trials have examined the benefits and adverse effects of morphine or fentanyl for ventilated neonates and other indications. This paper summarizes the current evidence for opioid dosing in newborns, reviews their side-effects and explains the use of population kinetics and non-linear mixed-effects modeling to analyze the data from clinical trials. Opioid use should be reserved for severe pain postoperatively or during intensive care in neonates, using continuous infusions rather than intermittent boluses. The safety and efficacy data from prolonged opioid use, particularly on the long-term outcomes of neonates, is still lacking. The pharmacodynamics and pharmacogenetics of opioid use in infancy needs further investigation, using non-linear mixed-effects models to drive individualized therapy. The current interest in opioid research will reap rich dividends in providing pain relief for neonates and avoiding dangerous side effects.

Is splenectomy for massive splenomegaly safe in children?

PURPOSE: To study and analyze the causes, etiology, morbidity, mortality and therapeutic value of splenectomy performed for massive splenomegaly in children. METHODS: The medical records of 115 children less than 18 years old who had splenectomy for various hematological disorders were reviewed. Twenty of them had splenectomy for massive splenomegaly (spleen weight > or =1,000 g). The records of these were reviewed for age at operation, gender, hematological diagnosis, indication for splenectomy, operative procedures, postoperative complications, and outcome. RESULTS: Twenty children had splenectomy for massive splenomegaly. There were 16 males and 4 females. Their ages ranged from 4 to 15 years (mean 11.2). Twelve had sickle cell disease, 5 had sickle-beta-thalassemia, 1 had beta-thalassemia major, 1 had thalassemia intermediate, and 1 had chronic myeloid leukemia. The indications for splenectomy were hypersplenism in 11, recurrent splenic sequestration crisis in 8, and splenic abscess in 1. The transfusion requirements in the patient with beta-thalassemia major decreased markedly postoperatively from 18 transfusions/year to only 4 transfusions/year; and for those with hypersplenism, there was a marked improvement in their blood parameters following splenectomy. The patient with thalassemia intermediate required no more blood transfusions. There was no mortality. The immediate postoperative morbidity was 10% for those with massive splenomegaly compared with 6.3% for those with splenomegaly <1,000 g. CONCLUSIONS: With good perioperative management, splenectomy in children with massive splenomegaly is both safe and effective.

Surgical considerations for pulmonary actinomycosis.

BACKGROUND: Diagnosis and treatment of pulmonary actinomycosis is difficult without surgical intervention. METHODS: Thirteen patients (10 men, 3 women; mean age, 62 years) underwent pulmonary resection and were given a pathologic diagnosis of pulmonary actinomycosis at our institution between 1976 and 2001. To clarify when pulmonary actinomycosis should be suspected in patients and the role of surgical intervention, we reviewed preoperative clinical characteristics, computed tomography findings, surgical indication, operative procedure, postoperative clinical course, and outcome. RESULTS: Ten patients (77%) had poor oral hygiene. Twelve patients (92%) were symptomatic, and 10 patients (77%) had hemoptysis. The mean interval between radiographic identification of the abnormality and surgical intervention was 8 months (interquartile range, 3.25 to 8 months). Computed tomography findings in all cases included radiologic opacity with air bronchogram or a low attenuation area. Lung cancer was diagnosed initially because of computed tomography findings of spiculation or pleural indentation, and operation was required in 8 patients (62%). The others were diagnosed with chronic pneumonia, and surgical intervention became necessary because of recurrent hemoptysis or prolonged illness. Six patients underwent lobectomy; the others underwent partial resection or segmentectomy. Neither complication nor recurrence has occurred. CONCLUSIONS: When patients, particularly those with poor oral hygiene, show radiologic opacity with an air bronchogram or low attenuation area on the computed tomography scan, pulmonary actinomycosis should be considered and penicillin should be administered as diagnostic therapy. Surgical intervention may be necessary when frequent hemoptysis has no resolution or lung neoplasm cannot be ruled out.

Aprotinin reduces operative closure time and blood product use after pediatric bypass.

BACKGROUND: The use of aprotinin in children undergoing cardiopulmonary bypass is controversial. We hypothesized that aprotinin would reduce blood product use and operative closure time in selected pediatric patients. METHODS: For a 6-month period starting in October 1999, consecutive cardiopulmonary bypass patients 6 months of age or less (n = 18) or having a repeat sternotomy (n = 18) received aprotinin. Similar consecutive patients from the preceding 6 months served as controls (n = 35 and 41, respectively). Data extracted from medical records included preoperative clinical characteristics, operative and postoperative procedures, and total blood product use. RESULTS: Patients in the aprotinin and control groups were well matched with regard to preoperative and intraoperative variables. Patients 6 months of age or less who received aprotinin required less operative closure time when compared with controls (median, 93 vs 127 minutes, p = 0.004), and trended toward requiring fewer red blood cell unit exposures (median, three vs five exposures, p = 0.07). Patients undergoing repeat sternotomy who received aprotinin required less operative closure time when compared with controls (mean, 126 vs 159 minutes, p = 0.007), fewer red blood cell unit exposures (median three vs four exposures, p = 0.002), and fewer fresh-frozen plasma unit exposures (median, zero vs one exposure, p = 0.007). CONCLUSIONS: Aprotinin reduced operative closure time and blood product exposure in pediatric patients undergoing cardiopulmonary bypass who were 6 months of age or less or underwent a repeat sternotomy.

Cecal necrosis after open-heart operation.

Two patients with isolated transmural ischemic necrosis of the cecum after cardiopulmonary bypass are discussed. Superimposed upon the multiple cardiovascular abnormalities in these patients, cardiopulmonary bypass adds another risk factor for nonocclusive intestinal infarction. In patients undergoing open-heart procedures, postoperative nonspecific abdominal complaints should be evaluated with a high degree of suspicion for this lethal complication. An intensive diagnostic effort is indicated, including contrast and angiographic radiological studies. Consideration of early abdominal exploration is indicated.

Cardiac operations in octogenarians: perioperative risk factors for death and impaired autonomy.

BACKGROUND: With the progressive aging of western populations, cardiac surgeons are increasingly faced with elderly patients. METHODS: We reviewed the records of 191 consecutive patients aged 80 years or older (mean age, 83 +/- 2.4 years) who underwent a cardiac surgical procedure at our institution from 1991 through 1996. RESULTS: Ninety-eight patients were men. Preoperatively, 32% of patients were in New York Heart Association class III or IV, and mean left ventricular ejection fraction was 0.55 +/- 0.02. One hundred ten patients (58%) underwent aortic valve replacement, 47 (25%) had coronary artery bypass grafting, 26 (14%) had combined aortic valve replacement and coronary artery bypass grafting, 5 (3%) underwent mitral valve replacement, and 3 (1.6%) had other procedures. Postoperative complications occurred in 69.1% of patients. The hospital mortality rate was 16.2%. Actuarial survival estimates at 1 year, 3 years, and 5 years were 79.2%, 74.9%, and 56.2%, respectively. Multivariate predictors (p < 0.05) of hospital death were preoperative pulmonary hypertension and lower left ventricular ejection fraction. Multivariate predictors of late death were combined aortic valve replacement and coronary artery bypass grafting and female sex. Sixty-four percent of long-term survivors were fully autonomous, and female sex was the only independent predictor of impaired autonomy. Eighty-three percent of survivors were satisfied with their present quality of life. CONCLUSIONS: Cardiac operations can be performed in octogenarians with a favorable long-term outcome. Earlier referral and intervention is mandatory to improve results in this patient population.

Brain SPECT imaging and neuropsychological testing in coronary artery bypass patients: single photon emission computed tomography.

BACKGROUND: Cognitive deficits appear frequently after cardiac operation. While the etiology remains unclear, alterations in cerebral perfusion during cardiopulmonary bypass may be causative. Single photon emission computed tomography (SPECT) scanning utilizes a radiopharmaceutical to provide images of cerebral perfusion. We proposed to study the cerebral circulation of patients during coronary artery bypass operation employing cardiopulmonary bypass. METHODS: Thirty-five neurologically normal patients underwent preoperative SPECT brain scanning and neuropsychological testing. A second SPECT brain perfusion scan was obtained by administering the radioisotope during cardiopulmonary bypass, with subsequent scanning upon completion of the procedure. Postoperative neuropsychological testing was performed prior to discharge. RESULTS: Fourteen (40%) of patients demonstrated significant neuropsychological decline. Patients who suffered cognitive impairment were no different in demographic, general health, or surgical variables. Patients who demonstrated neuropsychological decline had significantly poorer cerebral perfusion both at baseline and during operation. CONCLUSIONS: Impaired cerebral perfusion at baseline may identify patients at risk for cognitive injury after cardiac operation. Alterations in cerebral perfusion during cardiopulmonary bypass is common, and may be a factor in neuropsychological deficits seen after cardiac operation.
