[Letal rate and late complications following palliative surgery of transposition of the great arteria (author's transl)].

Between 1966 and 1973 145 palliative procedures were carried out on 110 infants with transposition of the great arteries. There were 23 early deaths (20.9 per cent). 85 per cent of the survivors were controlled till the end of 1974. Five late deaths and four cases of peripheral artery embolism were regarded. These complications, however, took place several years after palliation. The development of pulmonary hypertension doesn't seem to be as high as it is suspected sometimes. These results justify our conception, not to perform the Mustard-operation during the first two years of life.
