Abstract
Background Videoassisted thoracoscopic surgery VATS has emerged as an innovative and popular procedure for interruption of patent ductus arteriosus PDA while intraoperative transesophageal echocardiography TEE has proven to be an effective monitor in the evaluation of residual patency Previous reports on the adequacy of surgical interruption of PDA under VATS and TEE are available for pediatric patients but only limited information is available for adults with PDAMaterials and methods Between August 1995 and October 1997 we monitored 35 adult patients undergoing PDA interruption via VATS with HewlettPackard color Doppler multiplane TEE throughout the procedure The average PDA diameter was 102 ± 18 mm All the PDA were completely ligatedResults Thirtytwo patients showed no ductal flow after double ligation In the other three patients residual flow was detected intraoperatively after double ligation but it was quickly abolished by the third ligation One patient showed faint ductal flow by transthoracic echocardiography at postoperative followup but no reintervention was neededConclusions Our study showed that with the refinement of adult PDA interruption via VATS intraoperative multiplane TEE provides higher resolution for direct evaluation of the entire course of PDA ligation without interrupting the surgical procedure and minimizes the incidence of complications
