Use of direct-acting oral anticoagulants associated with improved survival and bypass graft patency compared with warfarin after infrageniculate bypass.

Objective: No consensus has yet been reached regarding the optimal antiplatelet and anticoagulant regimen for patients after lower extremity bypass. Usually, patients who have undergone below-the-knee bypass will begin oral anticoagulation therapy. Historically, the bypass has been with prosthetic conduits and the anticoagulation therapy has been warfarin.

Optimal conduit choice for open lower extremity bypass in chronic limb-threatening ischemia.

Open bypass surgery remains a major tool for limb salvage in chronic limb-threatening ischemia (CLTI). Although rest pain and tissue loss both fall into the category of CLTI, goals of revascularization are markedly different for each context. Rest pain mandates long-term patency considerations.
