Résumé
<p><b>OBJECTIVE</b>To evaluate one-stage arterial Switch operation for transposition of the great arteries (TGA) and Taussig-Bing with aortic arch obstruction.</p><p><b>METHODS</b>From January 2001 to June 2004, 8 patients had aortic arch obstruction, 3 with TGA and 5 with Taussig-Bing. Except one patient was 8 months old, all of others were 5 days to 3 months old, the mean operation age was (40 +/- 36) d and the mean weight was (4.3 +/- 0.5) kg. All patients were repaired by one-stage operation. The aortic arch obstruction was repaired in deep hypothermia circulatory arrest, and arterial switch procedure was performed in deep hypothermia and low flow perfusion.</p><p><b>RESULTS</b>There had 1 death who was 8 months old and had low cardiac output, complete artrioventricular block (AVB) and severe pulmonary hypertension postoperation. One patient was 3 months old who had asphyxia at 5 days postoperatively. Six patients followed up from 5 months to 2 years. One Taussig-Bing with interrupted aortic arch had residual obstruction at the anastomosis of aorta. Two had trivial aortic valve regurgitation, and one had mild pulmonary valve regurgitation.</p><p><b>CONCLUSIONS</b>One-stage repair for TGA and Taussig-Bing with aortic obstruction achieves excellent results. The reasons for the death were pulmonary hypertension and abnormal coronary artery. The operative procedure should be performed as early as possible for the better result.</p>
