BACKGROUND: Neopulmonary stenosis at anastomosis site is one of the most frequent complications after the arterial switch procedure for transposition of the great arteries. The surgical technique is a crucial factor associated with the frequency of stenotic complications. We present the outcomes of direct neopulmonary anastomosis during the arterial switch procedure in patients with simple transposition. This research was to assess the efficacy of this surgical technique based on the incidence of postprocedural supravalvular neopulmonary stenosis (SVPS).
METHODS: Among 545 patients operated on in our department between 1992 and 2009, the 346 consecutive survivors who had undergone simple transposition in the first month of life were included in this analysis. Switch procedures were performed with direct neopulmonary artery anastomosis in 318 patients (92%); in the remaining 28 (8%), the risk of coronary artery compression required the use of a pericardial patch for pulmonary reconstruction.
RESULTS: Neopulmonary stenosis occurred in 9 patients (2.6%): 5 had undergone direct neopulmonary reconstruction, and 4 had been treated with a patch. Balloon angioplasty of SVPS was performed twice in 1 patient. No patients required reoperation to treat neopulmonary stenosis. In multivariate analysis (logistic regression), patch reconstruction (odds ratio, 27.5; p=0.001) and nonfacing commissures (odds ratio, 11.1; p=0.004) were correlated significantly with the incidence of SVPS.
CONCLUSIONS: Direct neopulmonary artery anastomosis during arterial switch is an interesting alternative to patch reconstructions and ensures a good postoperative result with low rates of complications and SVPS.
