[Total cavo-pulmonary anastomosis in the surgery of complicated congenital heart defects].

The authors discuss experience in 8 operations for total cavo-pulmonary anastomoses in patients with various complicated congenital heart anomalies in which radical or anatomical correction could not be undertaken. The operation for total cavo-pulmonary anastomosis is an alternative of Fonten's method since many authors claim that the last-named has some shortcomings. Total cavo-pulmonary anastomosis was established in 4 stages under conditions of extracorporeal circulation. End to side cavo-pulmonary anastomosis was formed in the first stage; the proximal end of the divided superior vena cava was joined to the pulmonary artery in the second stage; the communication between the heart and pulmonary artery was closed in the third stage, and, finally, a tunnel was formed between the inferior and superior venae cavae by means of a xenopericardial flap in the fourth stage. Six patients tolerated the operation successfully. The immediate postoperative period was more favourable than after Fonten's operation. However, to come to a deeper general conclusion and compare the two methods clinical material must be accumulated and the long-term results of the operations studied.
