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.
