Educational Exhibit Abstract No. 373 - Splenic artery embolization as treatment for splenic artery steal syndrome after liver transplantation

Abstract

<h3>Learning Objectives</h3> Splenic artery steal syndrome is an underdiagnosed entity first described in 1991 and occurring in 3-8% of patients after orthotopic liver transplantation (OLTX). The purpose of this article is to describe five cases of splenic artery steal syndrome in a single institution. <h3>Background</h3> An imaging search engine was used to search for liver transplant patients with a diagnosis of splenic artery steal syndrome. Further chart review to evaluate for what treatment was performed, and the post treatment changes. <h3>Clinical Findings/Procedure Details</h3> Five liver transplant patients were found to have splenic artery steal syndrome. Of these five patients four received splenic artery embolization with or without hepatic artery angioplasty as treatment. The fifth patient did not have abnormal liver function tests and was untreated. All four treated patients demonstrated improvement in their liver function tests. <h3>Conclusion and/or Teaching Points</h3> Splenic artery embolization with or without hepatic artery angioplasty results in improved hepatic function in liver transplant patients presenting with splenic artery steal.
