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

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Devices

Background:

• The MVP™ Micro Vascular Plug System is designed for peripheral vasculature embolization.
• Current limitations restrict MVP™ use to vessels ≤9 mm due to its profile and deliverability.
• A novel technique is needed to expand MVP™ applications to larger caliber vessels.

Purpose of the Study:

• To introduce and evaluate a new embolization technique using the MVP™ and detachable coils.
• To assess the feasibility of treating larger caliber peripheral vessels ( >9 mm) with this modified approach.
• To determine the safety and efficacy of this technique in preventing plug migration.

Main Methods:

• A 7-F sheath was used for MVP™ implantation without detachment.
• A microcatheter was navigated in parallel for detachable coil placement.
• Coils were anchored using the bare portion of the MVP™ to stabilize the plug and prevent migration.
• The technique was applied in two patients with larger caliber vessels.

Main Results:

• 100% technical success rate was achieved in both cases.
• No complications were reported during or after the procedures.
• No MVP™ migration was observed at the one-month follow-up.
• The technique effectively occluded the target vessels.

Conclusions:

• This novel technique successfully expands the indications for the MVP™ system.
• It enables effective embolization of peripheral vessels larger than 9 mm.
• The combined use of MVP™ and detachable coils offers a safe and stable solution for challenging embolizations.
