[Progress and prospect of the treatment of lower extremity arteriosclerosis obliterans]

Abstract

In the past five years,both advancements and new problems were seen in the treatment of lower extremity arteriosclerosis obliterans.The Global Vascular Guidelines published in 2019 have given us comprehensive suggestions for the diagnosis and treatment of critical limb threatening ischemia(CLTI),but the grading and treatment suggestions for CLTI should be generalized.As to endovascular treatment,drug coated balloons have been found to be effective for limb salvage and graft patency in femoropopliteal and infra-popliteal artery occlusive diseases.As to surgical revascularization,persistent education and surveillance are necessary to maintain the practical quality of this fundamental technique.Inframalleolar bypass could achieve good graft patency and limb salvage rate for in CLTI patients.Regional anesthesia has been found to have lower risk than general anesthesia for lower extremity surgical revascularization.Percutaneous deep vein arterialization might be helpful for limb salvage in patients with non-option CLTI.A brief review about the treatment of lower extremity arteriosclerosis obliterans is performed based on latest literatures and institutional experience.Understanding the present situation and development trend is important for peripheral vascular practitioners.
