[Closure of patent ductus arteriosus in thoracoscopy: analysis of the experience in the Gaslini Institute of Genoa].

In 1993, Laborde et al described a new surgical approach for closure of the patent ductus arteriosus (PDA), using a videoassisted technique. For the first time, videosurgery was utilized in pediatric cardiovascular surgery. The advantages of this new method are that it is minimally invasive (thoracotomy is replaced by three small holes), it reduces postoperative pain, recovery is more rapid with a shorter hospital stay and convalescence, and last but not least, it offers better aesthetic results. Between July 1994 and June 1996, we utilized the videoassisted thoracoscopic technique described by Laborde in 23 patients with PDA (age: 8 m-12 yrs, mean 45.2 m +/- 37.8; weight: 5.3-32 kg, mean 23 kg +/- 10.3). In two patients, we converted the procedure to standard thoracotomy due to anatomic problems. Echo-doppler evaluation, performed in the operating room shortly after the procedure, confirmed the complete closure of the PDA in all patients. There was neither morbidity nor mortality. The average hospital stay was four days. At a mean follow-up interval of 7.2 months (range 1-13 months), all patients showed excellent cosmetic results. We conclude that thoracoscopic closure of PDA is a valuable therapeutic option that can be used as an alternative to open-chest surgery and interventional cardiology.
