Gelfoam-assisted amplatzer vascular plug technique for rapid occlusion in proximal splenic artery embolization.

Abstract

The objective of this study was to prospectively investigate the role of rapid Gelfoam-assisted occlusion of the splenic artery with an Amplatzer Vascular Plug (AVP). Ten consecutive proximal splenic artery embolizations were performed with AVP as the primary embolic agent and Gelfoam slurry as an adjunct. These cases were then compared with 10 retrospective cases of splenic artery embolization performed with AVP and augmented with coils or additional AVPs, or both, in patients with similar indications. Successful proximal splenic artery embolization using a single Amplatzer Vascular Plug and Gelfoam slurry occurred in all cases. No recanalization was identified on imaging follow-up at an average interval of 5.1 months. Gelfoam can be used as an adjunct to AVP in proximal splenic artery embolization. Using adjunctive Gelfoam is a simple, safe, and cost-saving method of improving the occlusion efficiency of the Amplatzer Vascular Plug.
