Abstract Background: Never had literatures characterized the relationship between the property of major aortopulmonary collateral arteries (MAPCAs) and outcomes of selective unifocalization of pulmonary atresia with ventricular septal defects and MAPCAs. Methods: This is a case-series study. Thirteen patients were included. Angiography-based assessment was conducted to determine whether collateral arteries should be unifocalized or treated with intraoperative ligature. Specimens were collected and stained by HE and ET+VG. Results: Twelve patients underwent one-stage unifocalization at a median age of 37 months (range: 6–228 months) and a median weight of 14.0 kg (range: 5.0–49.0 kg), which produced a favorable right… More >

Abstract Background: This study aims to explore the efficacy of selective unifocalization (UF) for major aortopulmonary collateral arteries (MAPCAs) unifocalization in children with pulmonary atresia with ventricular septal defect (PA/VSD). Methods: A retrospective analysis of 13 patients with PA/VSD/MAPCAs who underwent surgery from June 2017 to December 2019. Sex, age, preoperative cardiovascular angiography test results and McGoon ratio were collected. The properties of the collateral arteries were evaluated by angiography, and selective UF for the “dendritic” MAPCAs and ligation of MAPCAs demonstrating distortion and resistance. Results: A total of 13 severe patients underwent one-stage repair, of which 1 More >
