Connection of Discontinuous Pulmonary Arteries in Patients With a Superior or Total Cavopulmonary Circulation

摘要: Background Discontinuous pulmonary arteries (PAs) may develop in patients with single-ventricle heart disease from a variety of causes. We investigated factors associated successful connection nonconfluent PAs cavopulmonary circulation. Methods reviewed 49 who underwent discontinuous or after bidirectional Glenn (n = 29) Fontan 20) procedure at median age 7.9 years. PA continuity was established by direct anastomosis 27, interposition graft 19, and transcatheter recanalization 3. Survival 92% ± 4% 1 year 89% 5% 5 Results Recurrent occlusion documented 7 patients, within 10 days connection. The only factor shorter freedom sole supply blood flow to lung systemic-to-PA collaterals before (66% 14% vs 95% 6 months, p 0.03). Among the 45 early survivors, reintervention 83 6% 55 9% 3 Conclusions can be successfully connected most circulation, although appear increase risk poor outcome Fontan. usually diagnosed postoperative period. In through collaterals, shunt placement optimize outcome. A low threshold for investigation reconnected is warranted.
