Removal of Migrated Vascular Closure Device Plug Material From the Popliteal Artery Using the Bi-Directional Approach "Push Balloon Into Vessel and Close Embolus From Retrograde Site (PINCER)" Technique: A Case Report.

Abstract

Vascular closure devices (VCDs) are widely used to achieve rapid hemostasis after percutaneous intervention via the common femoral artery (CFA), with well-established efficacy and safety. Although VCD-related artery occlusion is rare, it can be critical. A 72-year-old female underwent endovascular therapy (EVT) for stent occlusion in the left superficial femoral artery through a 7-Fr guiding sheath from the right CFA. After the procedure, an acute right popliteal artery (POP-A) occlusion, associated with the EXOSEAL VCD plug, occurred. The plug material was successfully removed using a bidirectional approach. The migration plug was blocked to prevent distal vessel migration and pushed gently to close the antegrade system, using an over-the-wire balloon from the retrograde site. We named this the "Push balloon INto vessel and Close Embolus from Retrograde site" (PINCER) technique. Finally, the plug was successfully removed using biopsy forceps. Acute limb ischemia (ALI) caused by EXOSEAL is a rare condition. Removal of the emboli by EVT is clinically significant because it is minimally invasive. However, it is sometimes difficult to remove the embolus using only antegrade approach; thus, the bidirectional approach using the PINCER technique can be effective in these situations.
