DETERMINATION OF STENOZIS AND ARRHYTHMIA AFTER SURGICAL OPERATION OF PARTIAL ANOMALOUS PULMONARY VENOUS DRAINAGE IN MID&LONGTERM (COMPARISON OF DOUBLE/SINGLE PATCH AND WARDEN OPERATION IN PARTIAL ANOMALOUS PULMONARY VENOUS DRAINAGE): A COMPARATIVE STUDY OF TWO DIFFERENT TIME INTERVALS

Abstract

Objectives: We retrospectively investigated 20 patients who underwent partial anomalous pulmonary venous drainage (PAPVD) surgery with single patch, double patch, and Warden operation after surgical treatment in H……. Medical School, department of cardiovascular surgery and 62 patients who underwent surgery with double patch for PAPVD in Es and 10 patients in Mu Medical School at different time intervals. We compared postoperative v. cava superior stenosis, pulmonary vein stenosis and arrhythmia in regards of different surgical techniques. Methods: We constituted 2 groups: 20 patients of H….Medical School from 2005 to 2011 (group A) and 72 patients of M ..and E... Medical School from 2015 to 2022 (group B). The median age was 5.7 year (range 0.42-11 years), median weight was 18.67 kg (5.5-41 kg) in group A. The median age was 6.68 years (range 1-17 years), median weight was 23.58 kg (8-80 kg) in group B. Electrocardiographic and echocardiographic evaluations were obtained. Results: We found neither early nor late mortality in both groups. The mean follow-up duration were 39.73 months and 49.82 months respectively. No pulmonary venous or v. cava superior stenosis occurred during the follow-up in both groups. Reoperation for residual atrial septal defects required in 1 patient who underwent Warden procedure and 1 patient who underwent double patch technique (10%) in group A. It did not require reoperation in group B. In group A, 6 patients presented rhythm disturbance in early postoperative period, as well as 4 patients in group B. In follow-up all patient recovered to sinus rhythm in both groups. Pacemaker wasn’t required. Conclusion: PAPVD can be safely operated using different procedure. Meticulous dissection nearby sinus node (SA) should be emphasized to avoid injury of SN for all techniques. We believe that low-weight pediatric patients had a tendency to postoperative arrhytmia in our study.
