Case report of superficial femoral artery and popliteal artery aneurysm repair using brachial vein

Background Several veins have been well-recognized as acceptable conduits for infrainguinal bypass surgery when the ipsilateral greater saphenous vein is unavailable. However, there is a paucity of literature describing the brachial vein as an adequate alternative. In the absence of other viable autogenous conduits, we describe the use of a brachial vein as a successful alternative for lower extremity revascularization. Methods A 70-year-old man presented with a chief complaint of right calf pain. Duplex ultrasound imaging of his right lower extremity revealed right-sided 2.5 cm acutely thrombosed superficial femoral artery and popliteal artery aneurysms. The patient underwent a suction thrombectomy with tissue plasminogen activator using the Power Pulse feature and Solent catheter from the AngioJet® (Boston-Scientific, Marlborough, MA) system. To repair the thrombosed aneurysms, an open bypass was planned. Due to lack of viable alternative traditionally used venous conduits, a bypass was created using the patient’s brachial vein. Results A bypass was created from the superficial femoral artery to the P2 segment of the popliteal artery using a non-reversed brachial vein with ligation of the side branches of the superficial femoral artery and popliteal artery aneurysm from within the sac lumen. Completion angiogram revealed runoff through the anterior tibial artery only. Follow-up imaging at three months demonstrated a patent brachial bypass. Conclusion Brachial veins can be safely used as viable venous conduits for lower extremity bypass surgery and should therefore be considered as an alternative when more commonly used veins are unsuitable or unavailable. However, more research is needed to determine the potential opportunities and challenges this alternative may present.
