Original publication title: An intrapericardial technique for PDA ligation: surgical description and clinical outcome in 35 dogs.

Plain-English summary
A group of 35 dogs with a heart condition called patent ductus arteriosus (PDA) underwent a new surgical technique to close the abnormal blood vessel. The surgery took about an hour, and there were no complications during or after the procedure. Within two days, all dogs showed improvement, with most having no signs of the heart murmur associated with PDA. The new technique was successful, with only a small percentage of dogs showing any residual blood flow after surgery, which resolved in most cases.

Abstract
A number of surgical techniques have been reported for dissection and ligation of patent ductus arteriosi (PDAs) in dogs. The objectives of this study were to provide a detailed description of an intrapericardial technique for PDA dissection and ligation and to report the clinical outcome of that technique in dogs. Medical records of 35 dogs were retrospectively reviewed for signalment, clinical signs, echocardiographic findings, surgical time, intra- and postoperative complications, and completeness of ductal closure. Median surgery time was 60 min (range, 35-125 min). Neither intraoperative nor postoperative complications occurred. Within 48 hr of surgery, the continuous left basilar heart murmur was absent in all dogs, and complete echocardiographic closure was confirmed in 29 of 32 dogs. Residual flow was identified echocardiographically in three dogs within 48 hr of surgery. Residual flow was decreased in one dog at 1 mo, which resolved within 33 mo. One dog had mild residual flow postoperatively but did not return for follow-up. The intrapericardial technique was successful for PDA dissection and ligation and had a lower rate (6%) of echocardiographic residual flow compared with previously reported techniques.
