Coils associated with micro vascular plug system for closing larger vessels: Technical note on a preliminary experience.

Abstract

ObjectivesThe MVP™ Micro Vascular Plug System represents a plug indicated for embolisation of peripheral vasculature. It has a lower profile and can be deliverable through smaller catheters, but it can occlude vessels ≤9 mm. We propose a new embolisation technique based on the use of the MVP™ and detachable coils to embolise vessels of larger calibre.Materials and methodsThrough a 7-F sheath the plug is implanted without detaching it. Then, the vessel is navigated in parallel with a microcatheter through which some coils are detached using the bare portion of the MVP™ to anchor them. This will stabilise the plug avoiding its distal migration. We performed vessel embolisation using this technique in two patients.ResultsTechnical success was 100% with no complications. No MPV™ migration was observed after one month.ConclusionsIn selected cases, this technique allows to expand the indications of the MVP™ when it is undersized to the calibre of the vessel.
