BACKGROUND Tracheobronchial injuries are rare but potentially life threatening. Their successful diagnosis and treatment often require a high level of suspicion and surgical repairs unique to the given injury. METHODS We reviewed our experience with 32 patients with tracheobronchial injuries treated over the past 28 years. RESULTS Forty-one percent(More)
BACKGROUND Surgical repair of total anomalous pulmonary venous connection (TAPVC) is associated with high rates of mortality and need for reintervention. The purpose of this study was to identify variables associated with surgical mortality and, in particular, to define predictors of recurrent pulmonary venous obstruction. METHODS All patients who(More)
After orthotopic heart-lung transplantation and immunosuppression, a patient developed intractable nausea and vomiting in association with chronic cytomegalovirus infection. Chronic intestinal pseudoobstruction was documented by antroduodenal manometric study. The patient was treated with leuprolide acetate with resolution of symptoms and improvement of(More)
OBJECTIVE We evaluated focused training in coronary artery anastomosis with a porcine heart model and portable task station. METHODS At "Boot Camp," 33 first-year cardiothoracic surgical residents participated in 4-hour coronary anastomosis sessions (6-7 attending surgeons per group of 8-9 residents). At beginning, midpoint, and session end, anastomosis(More)
BACKGROUND Guidelines exist for prevention of sternal wound infections (SWI) in adults. There are no guidelines for pediatric patients and limited reports on SWI incidence. The purpose of this study was to determine the incidence of, and preventative practice regarding pediatric SWIs with a long-term aim to develop best practice guidelines. METHODS(More)
BACKGROUND Applications to cardiothoracic surgery training programs have steadily declined. The application cycle for 2004 marked the first time the number of applicants was lower than the positions offered. This survey reflects on this trend in applications and the perspectives of current and graduating residents. METHODS In June 2004, the Thoracic(More)
Filamentous fungal infections are associated with high morbidity and mortality in solid organ transplant patients, and prevention is warranted whenever possible. An increase in invasive aspergillosis was detected among solid organ transplant recipients in our institution during 1991-92. Rates of Aspergillus infection (18.2%) and infection or colonization(More)
Eleven goats (mean weight, 69 +/- 16 kg) underwent 5 hrs of normothermic nonpulsatile cardiopulmonary bypass (CPB) using as priming fluid either a Ringer's based crystalloid priming solution (CP, n = 5) of a hyperosmolar oxyreplete hemosubstitute (HS, n = 6). The HS contained 20% w/v perfluorocarbon (perfluorodecalin), its osmolarity was 800-900 mOsm/1, and(More)
