Objective To investigate how to choose the methods of surgical treatment for Scimitar syndrome. Methods From Jan. 1999 to July 2004, the clinical data of 12 patients with Scimitar syndrome were analyzed retrospectively, 10 patients underwent repair by intra-atrial baffles approach, one patient by connecting scimitar vein and left atrium with artificial blood vessel under cardiopulmonary bypass, and one patient by directly reimplanting the scimitar vein to left atrium without cardiopulmonary bypass. Results All the 12 patients had no perioperative or late deaths and none of them required reoperation. Follow-up was extended from 1 to 36 months, echocardiography demonstrated a patent anastomosis in all patients without any evidence of restenosis. Conclusions Surgical approaches to Scimitar syndrome is based on the anatomic and pathologic features presented in each case. Approriate method will have good result.
