Superficial Femoral Artery Access for Infrainguinal Antegrade Endovascular Interventions in the Hostile Groin: A Prospective Randomized Study

Abstract

In a hostile groin, it may be difficult to perform antegrade endovascular procedures at the lower extremities using the ipsilateral common femoral artery as vascular access; therefore, the use of the ipsilateral superficial femoral artery (SFA) could be a useful alternative. In this study, we evaluated the feasibility and safety of ultrasound-guided SFA puncture versus traditional SFA cutdown to achieve arterial access. This prospective observational randomized study examined patients with symptomatic peripheral arterial disease who required endovascular interventions at the lower extremities. A hostile groin was defined as a high femoral bifurcation, obesity, and surgical scarring due to previous surgical interventions. A 6-Fr sheath (12cm long; ULTIMUM EV INTRODUCER; Abbott, Plymouth, MN, USA) was used in all procedures. In the percutaneous group, the puncture was performed under ultrasound guidance and hemostasis was performed using a percutaneous closure device (PCD) (ANGIO-SEAL VIP 6-Fr; Terumo Medical Corporation, Somerset, NJ, USA). The primary end points were technical success and perioperative complications. The secondary end points were the time required for the management of vascular access and the type of anesthesia administered. Between 2020 and 2021, 107 patients who underwent antegrade revascularization were enrolled. SFA was achieved in 50 cases by the femoral cutdown technique (c-group) and in 57 cases by percutaneous ultrasound-guided puncture (p-group). In the c-group, the time from incision to sheath introduction and the time of suturing the artery and wound closure was 35±8min. In the p-group, the time from skin puncture and sheath placement plus that from the sheath removal and hole closure with the PCD was 6±3min. For the c-group versus p-group, the following variables were as follows: high bifurcation, 10 vs. 6 cases (P = 0.2); severe obesity, 33 vs. 40 cases (P = 0.46); and previous surgical groin interventions, 7 vs. 9 cases (P=0.53), respectively. The technical success rates were 100% vs. 96.49% for the c-group versus p-group, respectively (P = 0.63). Two percutaneous puncture failures were managed using the cutdown technique. In the p-group, 2 postprocedural hematomas were recorded, with only one requiring surgical treatment and 2 with SFA occlusion to intravascular cap hemostatic dislocation, which were subjected to surgical revision. A total of 3 percutaneous procedures in the p-group required surgical revision versus none in the c-group (P=0.1). Within 3months, complications consisted of 6 cases of surgical wound complications in the c-group versus none in the p-group (P = 0.009). All procedures in the p-group versus 72% of patients in the c-group were managed with local anesthesia (P<0.0001). The femoral cutdown technique seems to be a safe and successful approach for achieving vascular access in cases of hostile groin. Ultrasound-guided puncture and PCD make SFA puncture a successful and safe alternative with an acceptable complications rate. Moreover, it reduces the time required to manage vascular access and can be performed mainly under local anesthesia.
