Lower extremity ischemia is a serious complication in patients treated with venoarterial extracorporeal membrane oxygenation (vaECMO). The Extracorporeal Life Support Organization (ELSO) database reports a 5% incidence of ischemic leg complications, leading to leg amputation in 1% of the vaECMO runs. Pacing a distal perfusion catheter (DPC) in the superficial femoral artery and confirming correct placement are essential.
We present a patient with primary graft dysfunction after heart transplantation. vaECMO was instituted surgically in the right femoral artery and vein with an ipsilateral 6 Fr, 24 cm DPC (CL-07624, Arrow, Athlone, Ireland) in the common femoral artery. As a result of multiple percutaneous coronary interventions in the past, visual confirmation of the correct placement of the DPC was difficult during surgery. Postoperatively, no Doppler flow could be measured in the popliteal artery. We inserted a “J”-tipped guidewire (0.81 mm, 60 cm, CS-25855, Arrow, Athlone, Ireland) into the DPC and visualized the wire in the popliteal artery using ultrasound (Figs. 1, 2, video in the ESM), confirming the right position.
