Video-thoracoscopic surgical interruption of patent ductus arteriosus. Routine experience in 332 pediatric cases.
OBJECTIVE
Pediatric video-assisted thoracic surgery closure of patent ductus arteriosus can now be performed on a routine basis. We review here our entire experience with this technique.


METHODS
Three hundred and thirty two consecutive patients underwent video-assisted closure of patent ductus arteriosus from September 1991 to September 1996. Indications were symptomatic ductus or failure of closure in older children. All complications were carefully noted, as well as intensive care unit stay, and operating room time.


RESULTS
Patients were divided in three age groups: less than 6 months (101 patients, 31%), 6-48 months (179 patients, 54%), greater than 48 months (52 patients, 16%). The mean weight was 12.6 kg (range 1.2-65 kg). Associated cardiac anomalies were atrial septal defect (3), ventricular septal defect (5), anomalous pulmonary venous return (1). Six patients had a residual shunt following video-assisted interruption. Five patients had successful immediate clip repositioning (three via video-assisted interruption, two via thoracotomy). One patient continued to have a small shunt, which is followed medically. Complications included recurrent laryngeal nerve dysfunction in six patients (1.8%) (five transient, one persistent). Mean operating time was 20 +/- 1.5 mn and hospital stay averaged 48 h (> 6 months), 72 h (< 6 months).


CONCLUSIONS
Interruption of patent ductus can be safely performed by video-assisted technique with minimal morbidity and no mortality. It can be performed in all age group with minimal hospital stay.
