The Annals of thoracic surgery

Traumatic extrathoracic lung herniation is an exceptional complication of blunt chest trauma. We report the case of a 46-year-old man who was involved in a motorcycle accident and who suffered a left clavicle fracture-dislocation associated with multiple rib fractures and massive herniation of the left upper lobe through an upper anterior chest wall defect. Immediate surgical repair through an atypical transcostal vertical thoracotomy resulted in full recovery of pulmonary function at 1 year.

The infant with a single ventricle and excessive pulmonary blood flow requires early protection of the pulmonary vascular bed to insure suitability for a subsequent Fontan procedure. The traditional approach, pulmonary artery banding, has had disappointing results. We have pursued an alternate strategy: division of the pulmonary artery, and placement of a systemic-to-pulmonary artery shunt. Potential sites of systemic outflow tract obstruction are simultaneously bypassed, by either a Damus-Kaye-Stansel, or modified Norwood procedure. ⋯ In patients with a functional single ventricle and excessive pulmonary flow, a strategy of pulmonary artery division and shunt, along with prophylactic bypass of systemic outflow obstruction, carries low operative and midterm mortality. It provides consistent protection of the pulmonary vascular bed, avoids subaortic stenosis and aortic arch obstruction, minimizes neoaortic insufficiency, and ensures suitability for progression along a Fontan pathway. These results provide a comparison for alternate strategies, including pulmonary artery banding.

Lesions of distal aortic arch and proximal descending thoracic aorta require a posterolateral thoracotomy approach and total circulatory arrest. Retrograde cerebral perfusion through the superior vena cava is technically difficult in such situations. We describe a simplified technique for delivery of retrograde cerebral perfusion through the left internal jugular vein.

Stroke is a rare but devastating complication after coronary artery bypass grafting (CABG) and its prevention remains elusive. We used a case control design to investigate the extent to which preoperative and perioperative factors were associated with occurrence of stroke in a cohort of consecutive patients undergoing myocardial revascularization. ⋯ Overall incidence of stroke is relatively low in our series. Age, unstable angina, previous CVA, PVD, serum creatinine greater than 150 mcg/ml, and salvage operation are independent predictors of stroke. These factors should be taken into account when informing each individual patient on the possible risk of stroke and in the decision-making process on the surgical strategy.
