title: Sutureless Patch Angioplasty for Postoperative Pulmonary Artery Stenosis in Congenital Cardiac Surgeries.
abstract: BACKGROUND
  Reconstruction of branch pulmonary arteries (PAs) can be demanding in redo congenital cardiac surgeries. Sutureless patch angioplasty could be a useful method to solve this problem, and we evaluated the feasibility of sutureless patch angioplasty for postoperative PA stenosis in patients who underwent congenital cardiac surgery.
  
  
  METHODS
  We retrospectively reviewed 28 patients (19 males and 9 females) who underwent sutureless patch angioplasty for postoperative PA stenosis between November 2004 and April 2015. The median age was 7.3 months (range, 4.3 to 54.7), and the median weight was 7.2 kg (range, 5.3 to 12.2 kg). Right PA angioplasty was performed in 5, left PA angioplasty in 10, and both sides in 13 patients. The most common original diagnosis was hypoplastic left heart syndrome (n = 18 of 28, 64.3%). Concomitant surgeries were the bidirectional cavopulmonary shunt in 24 patients, the Fontan operation in 3, and the Rastelli operation in 1 patient.
  
  
  RESULTS
  No operative death occurred. However, 2 late deaths were recorded, and both were unrelated to PA angioplasty. Mean follow-up duration was 60.9 ± 33.1 months. None of the patients had postoperative bleeding or thrombotic occlusion. No reoperation for PA restenosis was performed, and only 1 patient (3.6%) had a PA balloon angioplasty with a good result 12.9 months after the operation. Echocardiography or computed tomography angiography at the recent follow-up showed good branch PAs in all patients.
  
  
  CONCLUSIONS
  Sutureless patch angioplasty for postoperative PA stenosis could simplify PA angioplasty, and be a safe and effective method for PA reconstruction in patients who undergo congenital cardiac surgery.
