Two Different Minimally Invasive Techniques for Female Patients with Atrial Septal Defects: Totally Thoracoscopic Technique and Right Anterolateral Thoracotomy Technique

抄録

Background: To compare the outcomes of totally thoracoscopic technique (TTS) vs. right anterolateral thoracotomy technique (RALT) in female patients undergoing minimal invasive atrial septal defect (ASD) correction.Methods: From March 2011 to January 2013, 125 female patients underwent minimally invasive atrial septal defect closure, of whom 62 patients were in the TTS group and 63 were in the RALT group.Results: Procedures were performed successfully in all patients without in-hospital mortality or major complications. cardiopulmonary bypass (CPB) time were 48.95 ± 15.63 min in TTS group, 31.4 ± 8.04 min in RALT group (p <0.001); the cross-clamp time were 26.92 ± 11.84 min in TTS group and 18.51 ± 6.11 min in RALT group (p <0.001). The length of incision in RALT group (6.02 ± 1.03 cm) was longer than TTS group (5.31 ± 0.68 cm) and the difference was significant (p <0.001). The overall satisfaction rate for the cosmetic results of TTS was 100% and was 96.83% (61/63 patients) in RALT patients. During follow-up, all patients in TTS group were satisfied expect two patients complained that scar was too long at groin. Reasons for a lower score in RALT group included the long scar in the chest; a RALT incision that was located too medially (coming off the bra line) and asymmetrical breast development.Conclusions: Both TTS and RALT are valid and reliable cosmetic surgical techniques for repairing ASDs in female patients. Both techniques allow excellent cosmetic and functional results in most female patients. The totally thoracoscopic technique may gain shorter incision and cosmetic results compared with RALT.
