Uniportal endoscopic superior thoracic sympathectomy.

OBJECTIVE: A retrospective study presenting our experience with upper thoracic endoscopic sympathectomy in patients with primary palmar hyperhidrosis. METHODS: One hundred patients (46 women and 54 men) underwent bilateral uniportal endoscopic thoracic sympathectomy since January 1, 1995. Age distribution ranged from 12 to 54 years (mean, 23.4 yr). RESULTS: Sympathectomy on both sides was accomplished within 30 minutes in a single stage. Ninety-six patients (96%) had an uneventful postoperative course and were discharged the following day. Four patients with residual hemothorax required intercostal drainage and were discharged on the third postoperative day. Ninety-six patients were completely satisfied with immediate and permanent relief of palmar perspiration. Compensatory hyperhidrosis was the major complication, which was usually mild and tolerable after reassurance. In only eight patients (8%) was the compensatory hyperhidrosis considered bothersome, requiring treatment with aluminum chloride in ethanol solution at 25%. There was no mortality. Recurrence of palmar hyperhidrosis has been noticed in five patients (5%) during the follow-up period (range, 2-56 mo; mean, 12 mo). At the time of reoperation, a remaining branch of the sympathetic chain could be observed and coagulated. CONCLUSION: We consider thoracoscopic sympathectomy to be a simple, safe, and effective method for treating palmar hyperhidrosis. It is an effective method for treating patients with palmar hyperhidrosis, with a shorter operation time, fewer hospital days, and a better cosmetic result, as compared with the open approaches.

Spontaneous aortic rupture in a malignant schwannoma.

We have described a case of malignant schwannoma (MS) originating from the posterior mediastinum with subsequent pathologic rupture of the thoracic aorta. The patient presented with acute retrosternal pain radiating to the back, and she died on the day of admission. Necropsy revealed a large hemothorax and a tumor mass involving the thoracic aorta. The histologic features of the lesion fulfilled the criteria for delineated MS. We found no similar cases of thoracic MS with consequent aorta rupture.

Right atrial rupture due to blunt chest trauma.

Violent injury currently accounts for the majority of deaths among young people. Cardiac trauma is responsible for 15% of deaths from thoracic injury, and the incidence of cardiac injury in blunt chest trauma is as high as 76% in some clinical series. Many of these cardiac injuries consist of myocardial contusions. Recently, however, there has been increasing recognition of chamber disruption caused by blunt chest trauma. Cardiac injury is usually the result of direct compression of the heart between the sternum and the dorsal spine. These patients are frequently in extremis, with signs of pericardial tamponade, hypotension, and/or massive hemothorax. Successful management is dependent upon prompt diagnosis and surgical repair. To date there have been only 28 survivors (including the three patients in this report) of this catastrophic and frequently unrecognized injury.

Emergency department infraclavicular subclavian vein catheterization in patients with multiple injuries and burns.

We assessed the complications associated with emergency department placement of subclavian vein catheters in trauma and burn patients, reviewing the charts of all of the 441 patients admitted to the burn-trauma unit through the emergency department during 1983. Fifty-two patients (12%) had infraclavicular placement of subclavian catheters while in the emergency department. Sex, age, insertion site, blood pressure at time of insertion, indications for placement, catheters left in place, and complications were recorded. Patients with severe chest trauma or known pneumothorax or hemothorax on the ipsilateral side of line placement were excluded. The eight complications (15%) directly attributable to the procedure itself were one pneumothorax, two hematomas at the site of insertion, one knotted catheter, two misplaced catheters, and two episodes of sepsis, confirming the higher complication rates for emergency subclavian catheter insertion. Two upper extremity, 14 gauge percutaneously placed intravenous catheters are usually sufficient for resuscitation; femoral and cutdown routes offer additional sites for massive resuscitation. Subclavian catheterization is seldom needed in the emergency room. Any intravenous lines inserted in the emergency room should be changed within 24 hours to minimize infection.

Diffuse large cell lymphoma of the lung: an unusual cause of complete opacification of the hemithorax.

Complete opacification on chest radiographs may be due to collapse of the lung, consolidation, massive pleural effusion, empyema, hemothorax, chylothorax, fibrothorax, and other causes. We report a case of complete opacification of the hemithorax produced by large cell lymphoma, a previously unreported cause of this finding. Diagnosis was complicated by the CT finding of replacement of the lung parenchyma by a soft-tissue mass with an associated small pleural effusion, while bronchoscopy failed to reveal any major airway obstruction. Large cell lymphoma should therefore be added to the differential diagnosis when considering causes of complete opacification of the hemithorax. Both the patient and his brother had the combination of Lowe's syndrome and cancer.

The role of preoperative pulmonary function tests in patients with adolescent idiopathic scoliosis undergoing posterior spinal fusion.

STUDY DESIGN: A retrospective review of the case records and radiographs of 133 patients with adolescent idiopathic scoliosis who underwent posterior spinal fusion and instrumentation between 1986 and 1992. OBJECTIVES: To evaluate the incidence of abnormal results on preoperative pulmonary function tests and their correlation to immediate postoperative pulmonary impairment in patients with adolescent idiopathic scoliosis who had posterior spinal fusion. SUMMARY OF BACKGROUND DATA: It has been stated that preoperative pulmonary function tests are essential to assess surgical risk in a patient with scoliosis because of the possibility of further compromising the pulmonary function. Authors of previous studies have reported on the increased incidence of postoperative pulmonary complications in patients undergoing anterior spinal surgery. METHODS: The case records and radiographs of 133 patients with either a thoracic or a double-major curve, who underwent posterior spinal fusion, were reviewed. The presence of any preoperative or postoperative cardiopulmonary symptoms and increased requirement of postoperative ventilatory support were noted. Results of preoperative pulmonary function tests were classified as normal, restrictive, or obstructive disease. Postoperative chest radiographs were examined to note the presence of atelectasis, infiltrates, pneumothorax, hemothorax, or pneumonia. RESULTS: The majority of patients (72.9%) had normal results on pulmonary function tests. The mean coronal Cobb angle of the thoracic curve was 48 degrees, and the mean angle of kyphosis was 26 degrees. None of the patients had any increased requirement of postoperative ventilatory support. The overall incidence of postoperative pulmonary complications was 2.3%. CONCLUSIONS: Performance of a thoracoplasty was the only risk factor for postoperative pulmonary complications in patients undergoing posterior spinal fusion. There was no correlation between deterioration of preoperative pulmonary function and the risk of postoperative pulmonary complications. It appears that performance of preoperative pulmonary function tests in patients with moderate adolescent idiopathic scoliosis-scheduled for posterior spinal fusion is not necessary.

Combined laminectomy and thoracoscopic resection of dumbbell-type thoracic cord tumor.

STUDY DESIGN: A study of five patients whose dumbbell or paraspinal tumors of the thoracic spine were managed by using thoracoscopic surgery is reported. OBJECTIVES: To report on the use of combined laminectomy and thoracoscopic resection for the management of dumbbell-type thoracic cord tumor. SUMMARY OF BACKGROUND DATA: Some posterior mediastinal tumors can be resected safely with video-assisted thoracic surgery. However, there are few reports on thoracoscopic resection of dumbbell and paraspinal tumors of the thoracic spine. METHODS: Five patients who received treatment for thoracic spine dumbbell tumors and paraspinal tumors were studied retrospectively. Three patients had dumbbell tumors, and two had paraspinal tumors of the thoracic spine. Preoperative evaluation of each patient included plain chest radiography, magnetic resonance imaging, and computed tomography. All patients underwent total resection by means of a combined posteroanterior approach, with thoracoscopic surgery for dumbbell tumors and thoracoscopic surgery alone for paraspinal tumors. In all patients, a gross total resection was achieved with this approach. All patients were observed for a minimum of 3 years. RESULTS: All patients regained their ability to walk 2 days after surgery, except for one patient who had a hemothorax. A gross total tumor resection, documented by magnetic resonance imaging, was performed on all patients. Follow-up imaging at 6 weeks, 1 year, 2 years, and 3 years after surgery did not show residual tumor or recurrence in any patient. To date, spinal instability has not developed in any patient. CONCLUSIONS: Combined laminectomy and thoracoscopic surgery may be a good alternative method for managing thoracic dumbbell tumors.

Medical complications in scoliosis surgery.

Several medical complications can occur after scoliosis surgery in children and adolescents. They include the syndrome of inappropriate antidiuretic hormone; pancreatitis; cholelithiasis; superior mesenteric artery syndrome; ileus; pnemothorax; hemothorax; chylothorax; and fat embolism. This review focuses on the pathophysiology, diagnosis, and treatment of the various conditions that occur after correction of spinal deformity. Attention is given to recent literature specifically related to scoliosis surgery. Surgical complications like urinary tract infection, wound infection, and hardware failure will not be addressed.

Thoracoscopy and video-assisted thoracic surgery.

Thoracoscopy is an old technique that has been recently revived with the development of video-endoscopic technology. Video-assisted thoracic surgery (VATS) is now an established surgical approach with proven benefits in the management of pleural diseases. It has been found to be particularly useful in establishing the diagnosis of pleural metastasis with an option for treatment. It also has an established therapeutic role in the management of the fibrinopurulent phase of empyema and the treatment of hemothorax. The technique is still continually evolving, and refinement of instrumentation promises to further reduce surgical trauma in selected procedures.

Pleural involvement in sarcoidosis.

Pleural sarcoidosis is no longer considered rare, as it occurs in about 3% of all cases of sarcoidosis. However, newer methods of detection may boost this level higher. High-resolution computed tomographic scanning has increased our detection of pleural nodules and pleural thickening. Other manifestations include pneumothorax, chylothorax, and hemothorax. Further studies of large numbers of patients are needed to determine the true prevalence of pleural involvement in sarcoidosis.

Pleural effusions in the intensive care unit.

The incidence of pleural effusions in the intensive care unit varies depending on the screening methods, from approximately 8% for physical examination to more than 60% for routine ultrasonography. Several factors contribute to the occurrence of pleural effusions in intensive care unit patients: large amounts of intravenous fluid are often administered, pneumonia is common, and heart failure, atelectasis, extravascular catheter migration, hypoalbuminemia, or liver disease are present in many intensive care unit patients. In surgical intensive care units, cardiac or abdominal surgery is often followed by pleural effusions, and in trauma patients, hemothorax is a dreaded event. Because no clinical parameter excludes pleural infection, and because of the impact of thoracentesis on diagnosis and treatment, this procedure should be performed unless contraindicated. Thoracentesis is safe in mechanically ventilated patients. The author discusses the following points regarding pleural effusions in the intensive care unit: screening intensive care unit patients for pleural effusion, safety of thoracentesis in patients receiving invasive mechanical ventilation, distinguishing exudates from transudates, and diagnosing and managing infected pleural effusions in critically ill patients. Lastly, the author suggests a research agenda for pleural effusions in intensive care unit patients.

Complications of central venous catheterization in critically ill children.

OBJECTIVE: Analysis of central venous catheterization complications in different access sites with the Seldinger technique. Patients and Methods: A prospective study (May 1992 through December 1996) of 308 central venous catheterizations in children of different ages in a pediatric intensive care unit. RESULTS: Access sites were the subclavian vein (76.3%), femoral vein (20.4%), and jugular vein (3.2%). The frequency of catheter placement-related complications was 22%, and the frequency of serious catheter placement-related complications was 2.9% (pneumothorax 1.9%, hemothorax 1%). Catheter placement-related complications were more common in the subclavian than in the femoral vein (chi-square, p =.02) for the larger bore catheters (chi-square, p =.01) and for the higher number of attempts (Student's t -test, p <.001). Catheter placement-related complications were not related to the age, weight, or whether the procedure was performed by the staff physician or resident. The overall complication rate for maintenance-related complications was 36%. Maintenance-related complications were more common in younger children (Student's t -test, p =.03). The most frequent maintenance-related complications were mechanical complications (catheter obstruction and central venous thrombosis), and these were higher for femoral access (chi-square, p <.01) and for catheters indwelling for a longer period of time. Infection was found in 5.8% of patients, mainly due to Staphylococcus epidermidis. Infection was not related to the site of venous access or to the length of time the catheter was left indwelling. CONCLUSIONS: Central venous catheterization can be performed readily in children of all ages with an acceptable degree of risk. The immediate complications were more frequent and severe for subclavian vein catheterization, and the highest risk factor was the number of attempts at catheter insertion. Although the most frequent late complications were mechanical, which were higher for the femoral access and long-indwelling catheters, femoral catheters can be left indwelling for longer periods if routine ultrasound follow-up is performed. Infectious complications were independent of the venous access site or the duration of catheterization.

Multidetector computed tomography and blunt thoracoabdominal trauma.

Computed tomography has had an increasing role in the evaluation of patients after blunt trauma. Important findings in thoracic trauma include acute traumatic aortic injury, pneumothorax, hemothorax, pulmonary contusions and lacerations, mediastinal hematoma, and diaphragmatic rupture. The solid abdominal viscera may lacerate; infarct; or suffer vascular, ductal, or pyelocalyceal disruption. The bladder and intestines may rupture. In abdominal pelvic trauma, the direction of applied force often results in an identifiable constellation of injuries. This article reviews how multidetector computed tomography (MDCT) is used in the trauma patient. Technical advances of increased cephalocaudad coverage speed and improved z-axis resolution intrinsic to MDCT, together with effective contrast utilization, make MDCT invaluable in the setting of trauma.

Sectional neuroanatomy of the upper thoracic spine and chest.

This is the second in a series of articles on the spine. The first reviewed the anatomy of the neck. Subsequent articles are planned to cover the anatomy of the middle and lower thoracic spine. Procedures and trauma of the upper thoracic spine and chest are fraught with potentially serious complications. Hemothorax, pneumothorax, nerve damage, pulmonary collapse, and thoracic aortic aneurysm are included in the list. This article provides anatomically accurate schematics of innervation of the upper thoracic chest and spine that can be used to interpret magnetic resonance images of the muscles and nerves. Cross-sectional schematics of the upper chest and spine were drawn as they appear in imaging projections. The relevant nerves were color coded. The muscles and skin surfaces were labeled and assigned the color of the appropriate nerves. An organized comprehensive map of the motor innervation of the upper chest and spine allows the physician to increase the accuracy and efficacy of interventional procedures. This could also assist the electromyographer in correlating the clinical and electrophysiologic findings with magnetic resonance images.

Sectional neuroanatomy of the middle thoracic spine (t5-t8) and chest.

This is the third in a series of articles on the spine. The first reviewed the anatomy of the neck. The second reviewed the upper thoracic spine and chest (T1-T4). A fourth article is planned for the lower thoracic spine. Procedures in the midthoracic spine include chest tube placement, trigger point injections, chemodenervation with botulinum toxin, video-assisted thoroscopic surgery, and spinal injections. Complications include pneumothorax, hemothorax, diaphragmatic irritation, sympathetic trunk irritation, postthoracotomy pain, and intradural abscesses.

Lung penetration by thoracostomy tubes: imaging findings on CT.

We have analyzed the radiographic and computed tomographic (CT) appearance of thoracostomy (chest) tubes inadvertently placed into the lungs. We have studied the clinical sequela of such malpositioning and discussed treatment options. Cases were collected from chest CT log book reports between January 1998 and January 31, 2005 which indicated or suggested intrapulmonary thoracostomy tube placement. CT scans were reviewed by the authors. The chest radiographs and medical records--including thoracic surgical reports--of those patients whose scans demonstrated intrapulmonary tube placement or indeterminate tube location were reviewed. Fifty patients, in whom 51 thoracostomy tubes were placed into the lungs, are included in this series. None of these tubes were described as intrapulmonary on reports of chest radiographs done before CT scanning. In 13 patients (26%), thoracostomy tube placements produced immediate improvement in pleural abnormalities. Dramatic increase or development of chest wall emphysema or pneumothorax was noted in 4 (8%) patients after tube placement. Twenty-five patients (50%) demonstrated either abrupt or gradual increase in pulmonary or pleural opacity on postplacement chest radiographs. Twenty-one (42%) had no apparent clinical complications. Thirteen (26%) had either prolonged air leaks or recurrent pneumothorax. Ten (20%) developed pneumonia. Retained hemothorax or empyema occurred in 8 (16%). Twelve patients (24%) required subsequent thoracic surgery. Intrapulmonary placement of thoracostomy tubes is probably more common than previously reported. This possibility should be considered when radiographs and CT scans are evaluated.

Peripheral lung nodules: fluoroscopically guided video-assisted thoracoscopic resection after computed tomography-guided localization using platinum microcoils.

OBJECTIVES: We sought to test the safety and efficacy of fluoroscopically guided, video-assisted, thoracoscopic resection after computed tomography (CT)-guided localization using platinum microcoils. SUMMARY BACKGROUND DATA: Video-assisted thoracoscopic (VATS) resection of small pulmonary nodules >5 mm deep to the visceral pleura fails to locate the nodule and requires conversion to open thoracotomy in two thirds of cases. Therefore, we developed a new technique for intraoperative localization of these nodules using CT-guided placement of platinum microcoils. This study tests the safety and efficacy of this technique in a Phase I human study. METHODS: Twelve patients with undiagnosed growing pulmonary nodules <20 mm were marked preoperatively using percutaneously placed CT-guided platinum microcoils. The coil was deployed adjacent to the nodule with the distal end of the coil placed deep to the nodule and the superficial end coiled on the pleural surface. The nodule and coil were excised using endostaplers guided by VATS and fluoroscopy. Histopathologic diagnosis was performed immediately after resection. RESULTS: CT-guided microcoil localization was successful in all patients. A small hemothorax and a pneumothorax requiring a chest tube occurred in 2 patients. Mean distance from visceral pleura to the deep edge of the nodule was 30.9 +/- 15.4 mm. VATS resection of the nodules (size = 11.8 +/- 3.2 mm) was successful in all patients. Mean microcoil localization, fluoroscopy, and operative times were 42 +/- 14, 3.1 +/- 2.0, and 67 +/- 27 minutes. A diagnosis of primary nonsmall cell bronchogenic carcinoma was made in 6 patients who then received a completion lobectomy. Six patients (hamartoma: 2, reactive lymph node: 1, bronchoalveolar cell carcinoma: 2, metastatic sarcoma: 1) did not receive further resections. CONCLUSIONS: Preoperative localization of pulmonary nodules using percutaneous CT-guided platinum microcoil insertion combined with operative fluoroscopic visualization is a safe, effective technique that increases the success rate of VATS excision.

Delayed hemopericardium after penetrating chest trauma: thoracoscopic pericardial window as a therapeutic option.

A 41-year-old male developed a hemothorax after sustaining a stab wound in the right chest. The patient was managed conservatively with thoracostomy tube drainage for 3 days and was subsequently discharged home. Two weeks later the patient returned to the hospital with pleuritic chest pain and shortness of breath. Imaging studies revealed a right-sided pleural effusion and an enlarged cardiac silhouette, which was consistent with pericardial effusion as per ultrasonography. Thoracoscopic exploration revealed an enlarged heart, that following pericardiotomy drained 400 mL of frank blood. Subsequently, cardiac contractility improved, and no further bleeding was evident.
