[Palliative surgery of transposition of great vessels associated with pulmonary stenosis].

Palliative treatment for transposition of the great vessels with pulmonary stenosis (combined or not with ventricular septal defect) was studied in relation with 24 patients operated upon at Laennec's Hospital in Professor Mathey's section between January 70 and January 74. Three therapeutic attitudes are possible according to whether or not an atrial septal defect is created (Blalock-Hanlon's operation) in combination with the systemic-pulmonary artery anastomosis, and according to whether the operations are performed in one or many steps. It seems that for the badly-tolerated forms of the new-born, combination of both operations seems to be the best attitude, the curative treatment being impossible at this age.
