title: Aorta-pulmonary artery shunts with expanded polytetrafluoroethylene (PTFE) tube.
abstract: Ten patients underwent an aortapulmonary artery shunt with a polytetrafluoroethylene (PTFE) tube between December, 1976, and October, 1977. Five of them were less than 1 month old. The diameter of the PTFE tube was 5 mm in 9 patients and 4 mm in 1 patient. Seven patients survived the operation. One of them had a clotted shunt, which was reoperated on successfully. Three patients died in the postoperative period, and all had a patent shunt. Overall patency was 90% (9/10). Congestive heart failure refractory to medical treatment developed in 1 patient with a patent Blalock-Taussig and PTFE shunt. In our institution, the Blalock-Taussig shunt is the procedure of choice. The PTFE shunt is used when the anatomy of a patient is unsuitable for a Blalock-Taussig shunt. A tube diameter of 5 mm is optimal for infants when further growth is considered, even if digitalization is necessary to control congestive heart failure.
