Abstract No. 335 - Initial clinical experience with a novel microcatheter-deliverable vascular plug

Abstract

PurposeTo discuss and evaluate the efficacy of the MVP™ Micro Vascular Plug system, a self-expanding vessel occlusion device, in peripheral and neurovascular applications.Materials and MethodsA retrospective review was conducted of six cases from August to September 2013, two cases of neurotrauma and four cases of hepatic arterial mapping prior to Y90 radioembolization. All six cases utilized the MVP-3 Micro Vascular Plug system for embolization, a self-expanding occlusion device comprised of nitinol and a partial PTFE cover intended for vessels ranging from 1.5 to 3.0 mm in diameter deliverable through a 0.021 inch inner diameter microcatheter.ResultsPrompt and complete occlusion of the target vessels was observed in all six cases without a necessity for a secondary embolization agent. Target vessels included vertebral, lingual, segmental hepatic, gastroduodenal, and supraduodenal arteries. Two vascular plugs were required in one of the neurointerventions given the complexity of the traumatic injury. No significant migration of the plugs was observed.ConclusionThe MVP™ Micro Vascular Plug system, currently available in the United States in a 3-mm system and deliverable through a 0.021 inch microcatheter, was effective in prompt occlusion of target vessels in both peripheral and neurovascular applications.
