Splenic artery steal syndrome in living donor liver transplantation: a case report.

ABSTRACT

Splenic artery steal syndrome (SASS) has only recently been recognized as a potential threat to transplanted livers. We report a case of SASS with progressive liver dysfunction that developed after living donor right lobe liver transplantation. SASS suspected by serial pre- and postoperative computed tomographic (CT) scans was diagnosed by celiac trunk angiography. It was successfully salvaged by splenic artery embolization. In this case, serial examinations of CT scans were useful to diagnose SASS. This case showed that portal hyperperfusion injury is a cause of liver graft dysfunction in SASS. The splenic artery embolization technique is a safe procedure that can be applied to treat such injury.
