Use of a totally implantable drug delivery system in a university-affiliated community hospital.

We reviewed our experience at the Western Reserve Care System with totally implantable drug delivery systems (IDDS) in cancer patients with vascular access problems. Fifty-one ports were placed in 50 patients. Forty-nine of the IDDS were placed under local anesthesia. One patient developed a hemothorax during placement. Two catheters were removed because of infection. Two catheters found to be occluded responded to flushing with streptokinase. All catheters remained functional up to the time of treatment completion or of the patient's death. The low morbidity and high success rates of IDDS should encourage placement early in the course of chemotherapy.

Management of penetrating wounds of the neck.

Management policies for penetrating wounds of the neck vary from mandatory surgical exploration to selective surgical exploration following extensive or minimal imaging investigation. In order to review the treatment protocol at Sheba Medical Center, Tel Hashomer, Israel, we retrospectively studied 21 patients who were treated between the years 1984 and 1989. Thirteen had gunshot injuries and eight had stab wounds. Eight patients had undergone immediate exploration of the neck. Four patients had died, but all of these latter patients had evidence for significant bleeding that could have been detected within a short time of admission. On the basis of our findings and previous studies, we conclude that: presenting features of neck injuries should be differentiated into two basic categories: immediately life-threatening and not immediately life-threatening. Immediately life-threatening features include overt massive bleeding, expanding hematoma, non-expanding hematoma in the presence of hemodynamic instability, hemomediastinum, hemothorax, and hypovolemic shock. In all of these cases, immediate surgical exploration is mandatory. Non-life-threatening features include any signs of vascular complication in a hemodynamically stable patient, signs of upper aerodigestive tract lesions (when initial treatment has already relieved respiratory distress) and peripheral neurological deficits. These patients should undergo thorough imaging investigations on the basis of which the need for and the nature of possible surgical intervention can be determined.

A retrospective analysis of laparoscopically assisted ventriculoperitoneal shunts.

BACKGROUND: During the last two years, laparoscopy has been utilized to facilitate the rapid, safe and direct placement of the abdominal component of ventriculoperitoneal shunts. This study was undertaken to review the feasibility, benefits, technique, and clinical application of laparoscopically assisted ventriculoperitoneal (LAVP) shunt placement. METHODS: A retrospective analysis of the records of six patients who underwent LAVP shunt placement was undertaken. The sex, age, technique, indication for surgery, comorbid conditions, complications operative time, results, and mortality were noted. RESULTS: All patients underwent successful shunt placement. This included placement in the face of previous abdominal surgery, including a percutaneous gastrostomy. The one major complication, hemothorax, was not associated with the laparoscopic portion of the procedure. CONCLUSIONS: Using basic laparoscopic skills and nonspecialized equipment, laparoscopic assistance in ventriculoperitoneal shunt placement offers easy, direct placement of the intraabdominal portion of the catheter in most situations and provides definite patient benefits.

Thoracic Outlet Syndrome: Follow-up on 33 Cases with Regard to Vascular Compression

This follow-up study on 33 operations performed for thoracic outlet syndrome (TOS) proves high efficiency in relieving neurological and arterial symptoms, whereas benefit to venous compression is somewhat less. Twenty-six patients (average age was 36 years) were operated on for TOS, seven of them on both sides. There was a higher incidence in females. All patients showed neurological symptoms. In 15, operations on various entrapment syndromes of the upper extremity were performed previously. Six patients presented with an incomplete resection of the first rib. Arterial compression symptoms were evident in 15 cases, symptoms of venous compression in 14 limbs. All patients underwent a resection of the first rib, bilateral in seven cases, using the axillary and supraclavicular approach. In seven patients, a cervical rib and scalenus muscles were resected additionally, in three patients bilaterally. In two cases a neurolysis of the brachial plexus was performed. Using the supraclavicular approach, no complications occurred. In one early patient using the transaxillary approach to a postoperative hemothorax required a revision. Neurological results after surgery showed a total release in 26 limbs (n = 33). In 14 limbs (n = 15) with arterial compression symptoms and in 6 (n = 14) with symptoms of venous compression the operation showed a curative effect.

Early and late onset bacteremia have different risk factors in trauma patients.

OBJECTIVE: The aim of this study was to identify risk factors and to describe epidemiological patterns for early-(EOB) and late-onset bacteremias (LOB) after trauma. DESIGN: A prospective study conducted on 141 consecutive trauma patients. SETTING: A general intensive care unit (ICU) of a university hospital. PATIENTS: All multiple trauma patients admitted to our general intensive care unit (ICU) from December 1990 to May 1992 were prospectively enrolled in the study. The following information was collected for each patient and recorded in a computer database: demography, severity of trauma according to the Abbreviated Injury Scale (AIS), severity of coma according to the Glasgow Coma Scale (GCS), presence of pneumothorax, pulmonary contusion, rib fractures, hemothorax, and abdominal trauma, use of mechanical ventilation, and placement of central venous catheters. Bacteremias were defined as EOB when onset occurred within 96 h after trauma, and as LOB when appearing after 96 h from trauma. RESULTS: Thirty-seven patients developed bacteremia during their ICU stay (26%): 11 (29.7%) EOB and 26 (70.3%) LOB. Gram-positive cocci were isolated more frequently in EOB than in LOB (chi 2 = 4.1, P = 0.04). The risk of EOB was significantly increased by the presence of pulmonary contusion [relative risk (RR) 15.0; confidence interval (CI) 1.99-113.25], pneumonia before the onset of bacteremia (RR 3.56; CI 1.17-10.69), AIS score greater than 32 and an abdominal injury score greater than 9 (RR 3.11; CI 1.02-9.49), while intravascular catheters and mechanical ventilation did not represent risk factors for EOB. LOB had a very different pattern and their risk was significantly increased by exposure to intravascular catheters (RR 4.96; CI 1.23-19.94) and to mechanical ventilation lasting more than 7 days (RR 3.6; CI 1.6-8.1). CONCLUSIONS: Scoring with the AIS of the abdominal and thoracic trauma at admission to the ICU appears a useful tool for identifying trauma patients at increased risk of EOB. A rigorous policy of catheter placement and maintenance as a means of reducing late bacteremias in trauma patients is essential.

Subclavian vein catheterization in critically ill children: analysis of 322 cannulations.

Complications in 322 percutaneous subclavian vein catheters placed in 272 children by the infraclavicular approach were investigated prospectively. Ages ranged from 4 days to 15 years. Incidents during catheter introduction occurred in 13 cases, and were more common when insertion was on the right side (p less than 0.01). Nine (2.8%) required urgent treatment: (6 pneumothorax, 1 hydrothorax, and 2 hemothorax). Anomalous lodging of the catheter tip was more common when insertion was on the right side (p less than 0.05). Complications during catheter maintenance were 3 venous thromboses, 3 catheter obstructions, and 7 migrations out of position. There was no significant difference in complications related to age. Catheter cultures were positive in 33 (17%) of 190 catheters cultured (27 through colonization and 6 through catheter-related sepsis). Staph. epidermidis was the organism most frequently isolated (19 cases; 58%). Catheterization time of more than 5 days and catheter-related sepsis were statistically associated (p less than 0.05). Staph. epidermidis isolation and duration of cannula use were statistically related (p less than 0.01). No catheter-related deaths occurred. We conclude that subclavian vein catheterization is a simple and useful procedure that entails relatively few serious complications when performed by experienced pediatricians.

Rupture of the ascending aorta after surgical resection for lung cancer--a case report.

A rupture of the ascending aorta which occurred in a woman on the 13th postoperative day following a right upper lobectomy with mediastinal lymph node dissection for lung cancer is reported herein. Fortunately, the patient was rescued from a cardiac tamponade and hemothorax by emergency operation. The operative findings suggested a traumatic rupture of the aorta, however, lymph node dissection of the mediastinum could not be excluded as a possible cause. Therefore, careful mediastinal lymph node dissection should be carefully performed in operations for lung cancer.

Thymic carcinoid--a case report and review of the literature.

We report herein a case of a patient with thymic carcinoid who was operated on twice and has been followed for 9 years. In 1979, the original tumor was removed through an emergency left thoracotomy incision done for a hemothorax caused by an anterior mediastinal biopsy. Tumor recurrence was found 6 years later and removal carried out through a median sternotomy. The patient has been working and enjoying life following radiation and chemotherapy for a total of 9 years after his first operation. Recurrent thymic carcinoid has been thought to carry a poor prognosis, but this successfully treated case has been followed up for a long time after the removal of his recurrent tumor. We present this case and discuss other such cases reported in the Japanese literature.

The successful surgical repair of a traumatic transection of the descending thoracic aorta: report of a case.

An 18-year-old man involved in a traffic accident presented with a left-sided hemothorax. After undergoing left chest tube drainage, he showed temporary stable hemodynamics for 7 h. Later, an emergency left thoracotomy was performed because of abrupt hemorrhagic shock. The intima and media of the descending thoracic aorta was completely transected, and a tube graft was successfully interposed with a simple aortic clamp in 47 min. The patient was eventually discharged from the hospital with no sequelae, such as paraplegia.

Surgery for descending thoracic aortic anastomotic aneurysms with a temporary external bypass method.

The surgical treatment of descending thoracic aortic anastomotic aneurysms is technically challenging. The purpose of this study was to evaluate the use of a temporary external bypass method as an intraoperative measure in the surgical treatment of anastomotic aneurysms of the descending thoracic aorta. An analysis of five consecutive patients who had undergone surgery for a collective seven descending thoracic aortic anastomotic aneurysms in our university hospital over a period of 14 years was conducted. A temporary bypass technique was used as an intraoperative measure in all the operations, four of which were performed with a right axillary to left external iliac artery bypass, while other sites were used in the remaining three. Systemic heparinization was able to be avoided in six operations and was markedly reduced in the remaining one. Although the major postoperative complication was coagulated hemothorax after six procedures, all patients recovered well and are still alive after a mean follow-up period of 8.2+/-1.5 (SEM) years. The results of this analysis led us to conclude that our temporary bypass method for treating descending thoracic aortic anastomotic aneurysm prevented the risks of anticoagulant administration for circulatory support, which contributed to the success of the operation. This method can be used as adjunct treatment for anastomotic aneurysms in the descending thoracic aorta.

Emergent surgery for 3 aged patients who refused elective operation for thoracic aortic aneurysm.

This report describes 3 aged patients undergoing emergent surgery who refused elective operation for a thoracic aortic aneurysm because of freedom from symptoms attributable to the aneurysm at the time of presentation. A 77-year-old woman with a thoracoabdominal aneurysm 57 mm in diameter at presentation had recurrent hemoptysis 12 months later. A 78-year-old man with a saccular type distal arch aneurysm 64 mm in diameter at presentation was transported with shock and hemothorax 27 months later. Another 82-year-old man with a saccular type distal arch aneurysm 60 mm in diameter at presentation was admitted with severe chest and back pain 36 months later. All of them underwent tube graft replacements of the aneurysm urgently and were discharged on foot. Aged patients with life-threatening events should not be denied surgical intervention because of excessive operative mortality and morbidity, even if they had previously refused elective surgery.

Clinical case discussion: anesthesia for Cesarean section in a parturient with a large intrathoracic tumour.

PURPOSE: To report the anesthetic management of a parturient with a large intrathoracic tumour, presenting for Cesarean section. CLINICAL FEATURES: A 28-yr-old parturient, gravida 1, presented at 33 weeks gestation with a one month history of increasing cough and dyspnea. A computed tomography scan demonstrated a large mass filling the right hemothorax, causing mediastinal displacement to the left and carinal compression. Both mainstem bronchi were compressed and there was near total obliteration of the lumens of the right lobar bronchi. A decision was taken to expedite delivery to allow for staging and treatment of her disease and Cesarean section was scheduled. She was seen in consultation and prescribed oxygen by nasal prongs, dextromethorphan for cough and ranitidine the evening before and the morning of surgery. A subarachnoid block was performed and a block to the upper thoracic dermatomes was achieved; surgery proceeded uneventfully with the patient's head and upper body elevated about 15 degrees from the supine. The patient was discharged to the medical oncology service for evaluation and treatment. CONCLUSIONS: Intrathoracic tumours are uncommon in pregnancy. The physiological changes of pregnancy may mask not only the initial presentation but also, even advanced intrathoracic disease. Regional anesthesia is the anesthetic of choice and is rarely contraindicated by maternal condition.

[Blunt traumatic rupture of right ventricle and pericardium].

A 60-year-old man was transferred to our hospital for blunt trauma of the chest suffered in a traffic accident. He had a weak pulse, and cardiopulmonary resuscitation was continued in the ambulance. Chest roentgenography revealed left hemothorax, and echocardiography revealed pericardial bleeding. He was immediately transported to the operating room, because of severe hypotension due to massive bleeding from the chest drainage tube. Median sternotomy was performed under stand-by cardiopulmonary bypass. There was projectile bleeding from the anterior wall of the right ventricle. The site of rupture was sutured with felt strip. A tear in the pericardium was also present at the apex. Postoperative recovery was uneventful. Fulda et al. reported that the incidence of combined pericadial and cardiac chamber rupture was 8% for those patients suffering blunt chest trauma, and that the rate of survival was less than 15% for blunt heart rupture. We have reported here successful repair of combined rupture of the right ventricle and pericardium.

[A case of traumatic aneurysm of the brachiocephalic artery].

Traumatic aneurysm of the brachiocephalic artery is rate. We presented a case of traumatic aneurysm of the brachiocephalic artery caused by traffic accident. A 28-year-old woman suffered a blunt chest trauma. A chest X-ray revealed a widening of the superior mediastinum and multiple rib fractures. CT scanning demonstrated left hemothorax with lung contusion and upper mediastinal hematoma. An aortography was performed which showed aneurysmal dilatation at the origin of the brachiocephalic artery. The patient underwent an operation 24 hours after chest injury. An aorto-right common carotid artery and right subclavian artery bypass with bifurcated Dacron graft was performed while monitoring temporary artery pressure. After resection of aneurysm, We found that about 3 cm longitudinal laceration of intima on the posterior wall of brachiocephalic artery. Her post operative condition was good and no neurological defect was noted.

Penetrating knife injury to the heart.

A 39-year-old man attempted to kill himself using a small knife to penetrate the left anterior chest wall because of trouble at work and with his girlfriend. On arrival at the emergency room, his consciousness was not clear and vital signs were unstable. The knife remained vertically located in the left anterior chest wall. A large left hemothorax was identified by chest X-ray, and moderate cardiac tamponade was detected by echocardiography. Left-sided chest drainage was performed by inserting a chest drainage tube, and about 2500 ml of hemorrhagic effusion was drained. An emergency operation was performed to relieve the cardiac tamponade and repair the penetrating cardiac injury. About an hour after arrival at the emergency room, a median sternotomy was performed in the operating room. The knife had injured the surface of the right ventricular outflow tract, the left lung, and the 3rd intercostal artery and vein. Cardiopulmonary bypass was immediately prepared for the repair of the cardiac injury. The wounds were successfully repaired with pledgeted sutures under cardiac beating. The postoperative course was uneventful with no sign of infection. The patient was discharged at 9 days after the operation. Here we have reported a case of successful surgical repair of a penetrating knife injury to the heart, which was managed by immediate resuscitation and emergency surgery.

[Blunt thoracic injury].

Of 161 patients with blunt thoracic injury, 135 were male (83.9%) and 26 were female. The most common cause of injury was traffic accidents (130 patients, 80.7%), followed by falls (22 patients), and crushing (7 patients). There were 46 third decade and 36 second decade patients. Thirty-two patients had single thoracic injury and the other had multiple organ injury. The most common associated injury was head injury (65 patients). Most traffic accidents involved motor cycle accident. Forty-four patients died, 32 within 24 hours, and 4 died to thoracic injury. These 4 patients were shock on arrival and died within 24 hours. The injury severity score, which was under 30 in 78.3% of patients, correlated to the mortality rate. Rib fracture was the most common thoracic injury in 96 patients followed by hemothorax in 91, pulmonary contusion in 79, and pneumothorax in 64. Most of the thoracic injuries were treated conservatively. Thoracotomy was performed in 6 patients. Other than one patient with rupture of the left pulmonary vein, 5 patients recovered. Continued bleeding at a rate of more than 200 ml/h from the chest drainage tube or no recovery from shock and large air leakage preventing re-expansion of the lung are indications for emergency thoracotomy. Thoracotomy should also be considered after conservative treatment in patients with continued air leakage or intrabronchial bleeding negatively affecting respiration. Indications for thoracotomy should be determined individually based on evaluating of vital sign.

Percutaneous US-guided biopsies of peripheral pulmonary lesions in children.

BACKGROUND: A wide variety of diseases in children can present with peripheral lung lesions. Minimally invasive percutaneous techniques are preferred diagnostic tools when thoracoscopic resection is not indicated. Significant improvements in US resolution have increased the range of its applications for many diagnostic and therapeutic purposes. OBJECTIVE: To determine the adequacy and safety of US-guided biopsy of peripheral pulmonary lesions in children. MATERIALS AND METHODS: A retrospective review was performed of the clinical, imaging and pathology records of 33 children (13 females and 20 males) in whom 38 US-guided percutaneous lung lesion biopsies had been performed between January 1996 and March 2004. Their mean age was 8.3 years (range 1-19 years, median 6.6 years). All procedures were done under general anesthesia and controlled respiration. Two techniques were used: a single-needle technique and a coaxial-needle technique. In each case, the data recorded included age, sex, lesion's location and size, number of cores, pathology results (adequate, inadequate and indeterminate), and complications. In order to categorize the sample, the lesions were divided into four groups based on the size of the pleural surface: group 1 1-5 mm, group 2 6-10 mm, group 3 11-20 mm, and group 4 21 mm or more. RESULTS: The mean pleural surface size of the lesions was 12 mm (range 2.3-24 mm). The coaxial-needle technique was used for 13 biopsies and the single-needle technique for 25 biopsies. Of the 38 biopsies, 32 were considered adequate (technical success 84%), 4 were truly inadequate, and 2 were indeterminate at the time of the biopsy, requiring surgical biopsy for confirmation. Minor complications occurred following 44% of the procedures, including: pain (n=5), small pneumothorax (n=4), pulmonary hematoma (n=4), atelectasis (n=4), small hemothorax (n=3), respiratory distress (n=1) and hemoptysis (n=1). No major complications occurred. No significant correlation was found between the size of the pleural surface and technical success (P=0.106) or the incidence of complications (P=0.23). Minor complications occurred following 6 out of 13 procedures using the coaxial-needle technique (16% of total) and following 11 out of 25 procedures using the single-needle technique (28% of total), with no statistically significant difference (P=0.1081). CONCLUSION: This small retrospective study suggests that US-guided lung biopsies are a safe and adequate method to sample peripheral pulmonary lesions in children, with a high rate of technical success and low morbidity, even for lesions with a small pleural surface (<5 mm).

Acute adrenal hemorrhage after blunt trauma.

OBJECTIVE: To determine the appropriate management of adrenal hemorrhage in patients with severe chest and upper abdominal blunt trauma. MATERIALS AND METHODS: We reviewed 7 patients who suffered from severe traumatic adrenal hemorrhage after a traffic accident (n = 4) or fall (n = 3). Contrast-enhanced CT images were analyzed for multi-organ traumatic injury, hematoma size, extravasation, and pseudoaneurysm formation. We also report their management including transarterial embolization (TAE) and follow-up findings. RESULTS: All 7 patients manifested multi-organ traumatic injury and hemothorax; 5 also had rib fractures, 5 had abdominal organ injuries (liver, n = 3; kidneys, n = 2; pancreas, n = 1); 2 had dorsal fractures, and 1 had a traumatic aortic aneurysm. On CT images, unilateral right adrenal hematomas ranging from 20 to 50 mm (mean 26 mm) in length and from 15 to 50 mm (mean 23 mm) in width were seen. In 6 patients these were localized, and they were followed without any intervention. The other patient had a massive hematoma with pseudoaneurysm and extravasation, who subsequently received TAE. At 3-month follow-up all patients were doing well. CONCLUSION: Information regarding the size of the hematoma and the presence of extravasation helps to select the appropriate management of patients with traumatic adrenal hemorrhage. TAE appears to be useful for treating patients with massive adrenal hemorrhage.
