Abstract

Background: Branch pulmonary artery (PA) occlusion during patent ductus arteriosus (PDA) stenting procedure is the main reason why branch PA origin stenosis was considered as a contraindication for PDA stenting. This study was designed to assess the incidence of branch PA jailing during PDA stenting for cyanotics with duct-dependent pulmonary circulation and its immediate outcome. Methods: All the completed PDA stenting patients in our hospital between April 2017 and June 2019 were retrospectively analyzed for branch PA jailing and its outcome. Results: Of 63 completed PDA stenting, there was branch PA jailing in 13 (20.6%) patients, all successfully recruited either by strut dilatation or by surgery. The median duration of ventilation was 16 (interquartile range [IQR]: 8-22) hours for jailed patients and 17.5 (IQR: 5.25-34.25) hours for nonjailed patients ( P = .978). Median intensive care unit [ICU] stay was 69 (IQR: 47.75-96) hours for jailed patients and 79.5 (IQR: 66.75-135.25) hours for nonjailed patients ( P = .394). Procedural mortality was 1 (7.6%) for jailed patients and 3 (6%) for nonjailed patients. Since all the jailed pulmonary arteries were recruited, there was proportionate growth of branch PA till the most recent follow-up. Conclusion: Jailing of branch PA does not increase the ventilation duration, ICU stay, or mortality risk if recruited immediately. Proportionate growth of branch PAs can be achieved in spite of jailing, if addressed aggressively. Branch PA stenosis should not be considered as a contraindication for PDA stenting.
