Conclusions
Our early survival outcome and the incidence of the PVO for RAI with TAPVC were satisfactory. Postoperative branch PVOs occurred in 39% of all patients. The PVOs were all in the apex side. Furthermore, the rotation of the apex into the ipsilateral thorax after surgery was evident in those with postoperative branch PVOs. The cut-off values of the postoperative V-A angle and ratio for the PVO prediction were 41° and 1.17, respectively. Further studies are necessary to examine whether strategies to reduce the rotation of the apex ameliorate PVO after TAPVC repair.
