Case Reports
Secondary abdominal compartment syndrome causing failure to wean from cardiopulmonary bypass.
The abdominal compartment syndrome has been associated with trauma or primary abdominal procedures. The secondary abdominal compartment syndrome which is not associated with a primary abdominal process is seen in burns and other clinical situations where aggressive fluid resuscitation is needed. This case report describes a secondary abdominal compartment syndrome that occurred during an elective coronary revascularization which resulted in an inability to wean from cardiopulmonary bypass (CPB). After a decompressive laparotomy was done, the patient was successfully weaned from bypass.

We developed a novel technique for tracheobronchial reconstruction after resection of carcinoma of the right upper lung involving the right main bronchus and lower trachea. Preliminary results of the technique are reported. ⋯ Despite this being a small series and short follow-up, this tracheobronchial reconstruction shows encouraging preliminary results with low mortality and morbidity, and could be an alternative to other methods for the treatment of carefully selected patients with advanced carcinoma of the right upper lobe.

Pheochromocytoma is a catecholamine-secreting tumor associated with clinical presentations ranging from paroxysmal hypertension to intractable cardiogenic shock. We report the use of central extracorporeal life support (ECLS) in a young woman admitted to the intensive care unit with cardiogenic shock. Her medical history included neurofibromatosis type I and pheochromocytoma. ⋯ ECLS permitted full recovery of left ventricular function. Right adrenelectomy was performed 4 months later. In this case, central ECLS was used to treat pheochromocytoma-induced cardiogenic shock complicated by pulmonary edema.

The standard operation for vascular ring with right aortic arch and aberrant left subclavian artery is ligamentum arteriosum division. A new surgical approach with primary translocation of the aberrant left subclavian artery to the left carotid artery, removal of the Kommerell diverticulum, and division of the ligamentum through left thoracotomy was recently applied. This study assessed the early outcomes of this approach. ⋯ Primary translocation of aberrant left subclavian artery with removal of the diverticulum and division of the ligamentum had excellent early outcomes and can potentially eliminate residual symptoms and late complications.

When a long segment of trachea is resected and grafted with a bioabsorbable scaffold, chronic contraction of the graft occurs, leading to substantial delayed native tracheal axial approximation. This phenomenon may allow for safe two-stage end-to-end tracheal reconstruction of large tracheal defects. We performed this trial to confirm that delayed tracheal axial approximation occurs in a mature animal model and to test the surgical feasibility of two-stage end-to-end tracheal reconstruction. ⋯ Delayed tracheal axial approximation after bioabsorbable grafting was confirmed in a mature animal model and allowed two-stage end-to-end tracheal reconstruction of large tracheal defects.
