Determination of Stenosis 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

We retrospectively investigated 20 patients who underwent partial anomalous pulmonary venous drainage (PAPVD) surgery with single-double patch, and Warden operation after surgical treatment in Hacettepe Medical School, department of cardiovascular surgery (group A) and 62 patients who underwent surgery with double patch in Eskişehir Osmangazi Medical School and 10 patients in Muğla Sıtkı Koçman Medical School (group B including 72 patients) at different time intervals. We compared postoperative v. cava superior stenosis, pulmonary vein stenosis and arrhythmia in regards of different techniques. We constituted 2 groups: 20 patients of Hacettepe Medical School between 2005-2011 (group A) and 72 patients of Muğla Sıtkı Koçman and Eskişehir Osmangazi Medical School between 2015-2022 (group B). Group A included 12 females, 8 males, the mean age was 5.7±3 years, ranging between 0.42 and 11 years, the mean weight was 18.67±9.01 kg, ranging between 5.50 and 41 kg. Group B included 39 females, 33 males, the mean age was 6.68±3.70 years, ranging between 1 and 17 years, mean weight was 23.58±14.75 kg, ranging between 8 and 80 kg. Clinical findings, electrocardiographic, echocardiographic evaluations were obtained. 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 in both groups. Reoperation for residual atrial septal defects required in 1 patient who underwent Warden procedure,1 patient who underwent double patch technique in group A. It didn’t 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. PAPVD can be safely operated using different procedures. Meticulous dissection nearby sinus node (SN) should be emphasized to avoid injury of SN for all techniques.
