Classic surgical interruption of patent ductus arteriosus was partially replaced by transcatheter endovascular closure in 1971. We describe a new technique for ductus closure by video-assisted thoracoscopic surgical interruption, derived from video-assisted endoscopic surgery. With the patient under general anesthesia and intubated, two 5 mm holes were made through the left thoracic wall. A video camera and specially devised surgical tools were introduced; such as scissors, dissectors, and clip appliers. The ductus was dissected, and two titanium clips were applied, completely interrupting the ductus. Thirty-eight patients were operated on from April 1991 to April 1992. Mean age was 23.3 months (range 1.5 to 90 months) and mean weight was 9.5 kg (range 2.4 to 25 kg). Six had associated lesions not necessitating immediate surgical treatment. All had successful closure of the patent ductus with the video-assisted technique, but two needed two such procedures, one because of incomplete immediate ductus closure and one because of partial opening of the clip after 24 hours. One patient had recurrent laryngeal nerve injury and four had pneumothorax on the left side. The usual hospital stay was 2 or 3 days. There were no other complications and no deaths. Video-assisted thoracoscopic surgical interruption was a rapid, safe, and successful technique for closure of the patent ductus arteriosus. Better dissection of the ductus decreased the risk of recurrent laryngeal nerve injury and that of clip opening. In the last 26 patients, in whom a 2 mm multiperforated catheter was used for chest drainage during the first hours, no pneumothoraces occurred. Video-assisted thoracoscopic interruption of the patent ductus arteriosus is feasible in low-weight infants, whereas transcatheter endovascular closure of the ductus usually is not possible. The technique will be applied to premature infants with new instruments designed for the size of these patients.
