Artventive endoluminal occlusion system for proximal splenic artery embolization

Abstract

We aimed to discuss and evaluate the technical success and efficacy of the ArtVentive endolumi-nal occlusion system (EOS) device for splenic embolization. A retrospective review was undertak-en for all patients in whom the EOS device was deployed for the purpose of splenic embolization. Data was collected by a search of splenic artery embolization procedures in the hospital comput-er database. Data was reviewed for all patients in whom an EOS plug was deployed. Patient de-mographics, technical aspects of the procedure and follow-up at one month were reviewed. We review the technical success and efficacy of this occlusion device. Six patients underwent splenic embolization with the EOS plug. There were 5 male and 1 female patients; age range was 24–88 years. Five 8 mm and one 5 mm EOS plugs were deployed for the occlusion of the splenic artery. The technical success rate was 100% occurring in all 6 splenic arteries. One patient underwent a second angiogram and subsequent splenectomy for persistent splenic hemorrhage. One patient had a subsequent splenectomy for bacteremia with the spleen as the suspected source. This ear-ly data supports the efficacy of the EOS plug for the embolization of the proximal splenic artery.
