下肢动脉硬化性闭塞泛大西洋协作组织分型的局限性与新分型的建立OA

Arteriosclerotic Occlusive Disease(ASO)of the lower extremities is one of the primary vascular diseases leading to disability in elderly patients.Historically,the selection of clinical treatment options has primarily relied on the Trans-Atlantic Inter-Society Consensus(TASC)Ⅱ classification system.However,with the iterative updates of vascular intervention techniques and the widespread application of novel devices,the limitations of the TASC Ⅱ classification in guiding the treatment of complex lesions have become increasingly prominent,posing challenges to clinical decision-making.Recent clinical practices and evidence-based studies have indicated that the pathological composition of intravascular obstructions,particularly acute and subacute thrombus burden,is a crucial factor determining postoperative vascular patency rates.In light of this,by incorporating cutting-edge technologies such as thrombus composition analysis,the construction of a novel classification system based on the pathological characteristics of obstructions holds promise for achieving precise selection of ASO treatment options,thereby improving patient outcomes.
