Abstract
adds time and trauma to the procedure, and the polytetrafluoroethylene prosthesis might increase the risk of thrombosis, especially in a low-pressure vessel. Read and coworkers reported on three patients in whom polytetrafluoroethylene has been used with no complications. Our two patients receiving the pericardial conduit had an uneventful recovery, and the patency of the PA was confirmed 6 months after the operation by computed tomography. Read and associates » did not specify their anticoagulation schedule; in our patients we discontinued anticoagulation on discharge from the hospital (seventh and twelfth postoperative days) with no problems. We conclude that in the rare case in which the PA must be replaced by a prosthesis, a conduit of autologous pericardium is an advantageous solution.
