Minimally invasive thoracoscopic closure versus thoracotomy in children with patent ductus arteriosus

Abstract

BackgroundPatent ductus arteriosus (PDA) is one of the most common congenital heart defects. Once diagnosed, an immediate pharmacologic or invasive treatment should be performed. The purpose of this work was to evaluate the safety and efficacy of surgical PDA ligation in children using video-assisted thoracoscopic surgery (VATS) in comparison with a conventional muscle-sparing posterolateral thoracotomy technique (MSPLT). Materials and methodsIn this single-center, retrospective study 173 children qualified for surgical PDA closure were enrolled. Patients were divided according to their weight and type of surgery performed. The groups consisted of patients operated through thoracotomy (54%) or VATS (46%). Operative characteristics, cosmetic effect, postoperative complications and long-term survival were evaluated. ResultsRegardless of weight, fewer complications were noted in children after thoracoscopic clipping. Fifteen VATS patients required intraoperative conversion to thoracotomy; however, adverse sequelae were not observed. Aesthetics seemed to be the major complaint after conventional surgery. We did not observe any statistically significant differences in the long-term survival between both groups. ConclusionsBoth techniques were shown to be safe and effective. Unsuccessfully performed thoracoscopic surgeries were safely converted to conventional thoracotomy. VATS, being a less invasive approach, leads to a better aesthetic effect and lower surgical complication rate.
