[Surgical repair for anomalous drainage of left superior vena cava to left atrium]

To investigate the characters and surgical treatment methods of anomalous drainage of left superior vena cava to left atrium.Clinical data of 8 cases were analyzed retrospectively.The patients aged from 6 months to 168 months with weight between 6 and 29 kg.The associated cardic lesions existed in all patients: 4 had partial atrioventricular septal defect (PAVSD),including 1 coronary sinus orifice atresia (CSOA), 1 ventricle septal defect (VSD), 1 ventricle septal defect associated with right ventricular outlet tract stenosis (VSD/RVOTS), and 1 atrial septal defect (ASD) and complete atrioventricular septal defect (CAVSD), respectively.No patient died. Preoperation diagnosis was in 1 case, intraoperation diagnosis in 5 cases,and postoperation diagnosis in 2 cases due to reoperation for hypoxemia.Three patients were repaired by intratrium tunnel, and the other 5 were managed by extracardic shunt.This lesion is easily missed in preoperation diagnosis,which can be avoided by awareness and careful inspection.The methods for management of anomalous drainage of left superior vena cava to left atrium depend on time of diagnosis and experience of surgeons.
