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

Objectives The MVP (TM) 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 (TM) and detachable coils to embolise vessels of larger calibre.Materials and methods Through 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 (TM) to anchor them. This will stabilise the plug avoiding its distal migration. We performed vessel embolisation using this technique in two patients.Results Technical success was 100% with no complications. No MPV (TM) migration was observed after one month.Conclusions In selected cases, this technique allows to expand the indications of the MVP (TM) when it is undersized to the calibre of the vessel.
