BACKGROUND: The presence of bilateral superior venae cavae may add complexity to the performance of a bidirectional Glenn procedure (BDG). Stagnation of blood flow between the two cavopulmonary anastomoses may increase the risk of thrombosis and impair central pulmonary artery growth.
METHODS: Forty patients underwent BDG from January 2004 to April 2011. The cohort was divided into two groups: those receiving bilateral BDG (b-BDG, n = 13) and those receiving unilateral BDG (u-BDG, n = 27). Operative, angiographic, and follow-up data were analyzed retrospectively.
RESULTS: None of the patients experienced thrombosis. There was no difference in actuarial survival rate (u-BDG vs b-BDG, 100% vs 92% at 5 years, p = 0.15). On follow-up angiography, no difference in central pulmonary artery index was noted (78.4 ± 45.5 vs 60.4 ± 32.1, p = 0.24). Central pulmonary artery stenosis was detected in 6 patients (4 with u-BDG and 2 with b-BDG), 4 of whom (2 from each group) underwent balloon pulmonary artery plasty before the Fontan procedure. There was no difference in freedom from reintervention for central pulmonary artery stenosis (93% vs 85% at 1 year, p = 0.59). The rate of Fontan completion was comparable between groups, with similar operative variables and satisfactory outcomes.
CONCLUSIONS: Bilateral BDG did not increase the risks of thrombosis and central pulmonary artery hypoplasia and can be performed safely without altering the outcome of the Fontan procedure.
