Objectives: To assess the feasibility of a retrograde approach for stent graft implantation for treatment of access site bleeding following transfemoral transcatheter aortic valve replacement (TAVR).
Background: Access site bleeding is a common complication of transfemoral TAVR. Percutaneous stent graft implantation may achieve hemostasis in these cases and avoid need for vascular surgery, however failure to advance a guidewire antegradely across the femoral artery may preclude stent delivery. We describe a cohort of patients in whom retrograde guidewire advancement following distal arterial puncture facilitated stent graft delivery.
Methods: A prospective TAVR registry was analyzed. Of 349 patients who underwent TAVR, 332 (95%) cases were performed via transfemoral access. Access site injury requiring stent graft implantation occurred in 56 (17%). In 4 (7%) patients antegrade wiring across the site of vascular injury was not possible and a retrograde approach for stent delivery was utilized.
Results: Distal vascular access was achieved via the superficial femoral or profunda arteries. Retrograde advancement of a polymer-coated 0.035” wire to the abdominal aorta, followed by stent graft delivery to the common femoral artery, was achieved in all cases. During a median (IQR) follow-up period of 198 (618) days (range: 46-2455) there were no deaths and no patients required additional vascular interventions.

B) Insertion of a Seldinger needle into the calcified superficial femoral artery (SFA, arrowheads) under fluoroscopic guidance. C) Retrograde advancement of a 0.035” guidewire from the SFA (arrow) towards the occlusive balloon inflated in the common femoral artery (arrowhead). D) Final angiogram of the stented femoral artery (arrow).
Conclusions: A retrograde approach for stent graft delivery is feasible and allows percutaneous treatment of common femoral artery injuries following TAVR in patients who are not suitable for the conventional antegrade approach.
