巨细胞动脉炎引起下肢间歇性跛行的诊疗进展

Progress in diagnosis and treatment of intermittent claudication of lower extremities caused by giant cell arteritis

下肢间歇性跛行是老年患者常见的主诉,最常见的原因为动脉粥样硬化,但巨细胞动脉炎(GCA)也可导致下肢动脉狭窄,引发此症状。诊断超声、磁共振血管成像(MRA)和CT血管造影(CTA)等影像学检查有特征性表现,结合临床特点与影像学检查,可有效区分这2类疾病,从而指导治疗。本文结合近年下肢GCA的研究成果,综述了最新的诊疗进展。

Intermittent claudication is a common complaint among the elderly. It is mostly caused by atherosclerosis but also by stenosis of lower limb arteries resulting from giant cell arteritis. Distinct characteristics can be observed of giant cell arteritis and atherosclerosis on such imaging modalities as sonography,computed tomography angiography and magnetic resonance angiography. The two conditions can be effectively distinguished by imaging findings and clinical features,providing guide for patient＇s management. In this article,we reported the progress in the diagnosis and treatment of intermittent claudication of lower extremities by reviewing recent studies on the condition caused by large-vessel giant cell arteritis.
