Of the various anatomical types of atresia, that of esophageal atresia and double fistula is said to be the least common. In most series, frequency is less than 1%. Seventy-eight patients with esophageal atresia were treated at the University of Virginia Medical Center between 1955 and 1983. Six of them had esophageal atresia and double fistula, and in 5 of(More)
The internal mammary artery has been advocated for use in bypass grafting owing to its superior long-term patency when compared to saphenous vein grafts. Concern exists that the flow through the internal mammary artery may be inadequate during periods of peak myocardial demand. This flow was investigated in 24 consecutive patients with a mean proximal left(More)
Ventral anomalies of accessory pulmonary tissue have been classified as "bronchopulmonary foregut malformations." Between July 1, 1981, and May 31, 1985, 10 children with bronchopulmonary malformations have been cared for on the Pediatric Surgical Service at the University of Virginia. Six patients had bronchogenic cysts, one in an extrathoracic location(More)
Fifty-five patients with primary small bowel malignancies were evaluated from 1955 to 1983. Twenty-seven patients (49%) had carcinoid tumors, 16 (29%) had adenocarcinomas, and 12 (22%) had leiomyosarcomas. The average age at presentation was 68 years (range: carcinoids, 27-82; leiomyosarcomas, 36-75; adenocarcinomas, 40-83). Carcinoids and leiomyosarcomas(More)
The operation of pulmonary valvotomy has been so brilliantly successful that its failure to achieve an ideal end result in certain cases deserves comment. In this report, some residual effects of isolated pulmonary stenosis that may persist after complete valvotomy will be considered. It will be seen that all of these are the result of very severe stenosis(More)
A 51-year-old woman underwent a transhiatal esophagectomy for a failed antireflux procedure. She did well for 15 months, when she developed evidence of hemoptysis followed by tracheogastric fistula. She underwent operative repair with the use of a pericardial patch to replace the membranous trachea and interposition of a latissimus dorsi flap to isolate the(More)
Bronchiolitis obliterans (irreversible small airway obstruction) is a late complication of heart-lung transplantation. Chronic immune rejection is believed to be the major cause of this complication. Our hypothesis was that denervation might contribute to airway obstruction. To test this hypothesis in the absence of immune rejection, we performed a(More)
The effects of chronic denervation on pulmonary vasculature are not well understood. Three groups of young pigs were prepared: (1) those receiving sham thoracotomy, (2) those having left upper lobectomy alone (innervated left lower lobe), and (3) those receiving left pneumonectomy followed by reimplantation of the left lower lobe (denervated left lower(More)
