Switching of the great vessels (arterial switch surgery) in transpositio vasorum

Since April 1992 the arterial switch operation (ASO) has been the treatment of neonates with transposition of the great arteries (TGA) at Rigshospitalet, Copenhagen. Thirteen mature neonates with TGA underwent ASO. Ten patients had simple TGA, two had TGA associated with a ventricular septal defect (VSD), and one had TGA with VSD and in addition moderate right ventricular hypoplasia. All patients survived the operation and are still alive. Perioperative bleeding was a problem in three cases. Eleven patients had an uncomplicated postoperative course. One patient had peri- and postoperative left ventricular failure and was reoperated after three months for a residual VSD. One child developed renal failure and needed peritoneal dialysis. The patients have been followed for 5.5 (range 0-12) months, they are all in good condition and thriving well. The presented early results after ASO justify continued recommendation of ASO as the operation of choice for TGA in neonates at Rigshospitalet.
