An 84-year-old woman with severe aortic stenosis underwent transcatheter aortic valve implantation (TAVI). Although preprocedural computed tomography revealed a calcification of the common femoral artery, the calcification did not involve the whole arterial circumference. Therefore, we used the Perclose ProGlide suture-mediated closure system (Abbott Vascular) to deliver a single suture to close the access site in her common femoral artery following the TAVI procedure.
We inserted a 14 Fr eSheath introducer sheath set (Edwards Lifesciences) and performed TAVI. Before removing the sheath, we advanced the knot with a knot pusher and pulled on the suture limb to close the access site. However, the knot and a circular cross section of the interior arterial wall were removed together from her body (Figure 1). We immediately delivered manual compression to the site and performed percutaneous long balloon inflation to stop the bleeding. Surgery was not required, and she spent the usual period of hospitalization for TAVI.
There have been no reports about such “avulsion injury” of the femoral artery with a suture-mediated closure system during TAVI. Our pathological analysis of the specimen revealed that it consisted of mainly intima of the blood vessels. Although there was no calcification at the puncture site, calcification was present around the site. This calcification might have cracked and injured the intima, resulting in the complication. We should consider the cut-down method in cases with calcification restricted to the region surrounding the puncture site when we perform TAVI in patients with severe aortic stenosis.
