Feasibility and Safety of Reverse Catheterization Technique of the Superficial Femoral Artery in Single-Stage Endovascular Treatment of Bilateral Infrainguinal Diseases.

Purpose: We evaluated the feasibility and safety of the reverse catheterization technique of the superficial femoral artery (ReCAT) for single-stage endovascular treatment (EVT) in patients with bilateral infrainguinal diseases. Materials and Methods: We retrospectively evaluated 24 consecutive patients (overall median age: 79 years; male patients: 21 [87.5%]) who underwent EVT for bilateral infrainguinal diseases. The objective of ReCAT was to perform single-stage EVT in patients with bilateral infrainguinal diseases with a one-time unilateral femoral artery puncture. The main outcomes were the incidence of puncture site complications, including major bleeding or hematoma requiring transfusion, pseudoaneurysm, and arteriovenous fistula, and ReCAT procedure-related arterial dissection or perforation, which were assessed by ultrasonography on the day after the procedure. The secondary outcome measures were in-hospital mortality and in-hospital amputation. Results: Reverse catheterization technique of the superficial femoral artery was successful in 23 (95.8%) of the 24 patients; it failed in 1 patient due to severe calcification and a previously implanted stent in the ipsilateral iliac artery. The median operation time, radiation time, and the volume of contrast media used were 108 (84-142) minutes, 37 (27-55) minutes, and 111 (80-157) mL, respectively. There were no incidences of puncture site complications and arterial dissection related to the ReCAT procedure. One case of vessel perforation in a branch of the ipsilateral superficial femoral artery occurred due to flipped guidewire injury. Conclusion: Reverse catheterization technique of the superficial femoral artery is safe and effective in performing single-stage EVT for bilateral infrainguinal diseases. It might also reduce the number of EVTs and complications due to multiple femoral artery punctures. [ABSTRACT FROM AUTHOR]
