Lower extremity vasculitis in giant cell arteritis: Important differential diagnosis in patients with lower limb claudication. Vasa. 2014 Sep;43(5):326-36 Authors: Sigl M, Hsu E, Scheffel H, Haneder S, Rümenapf G, Amendt K Abstract Most patients with peripheral arterial disease suffer from arteriosclerosis, the prevalence of which increases with age. In some of these patients, however, the ischemic symptoms are not caused by stenotic arteriosclerosis, but by large vessel giant cell arteritis (LV-GCA), a disease also predominantly affecting patients of the older generation. Identifying large vessel vasculitis is a challenge for all physicians caring for patients with peripheral artery disease. The results of invasive treatment such as bypass surgery and angioplasty of inflammatory vascular lesions differ fundamentally from those of patients with atherosclerosis. Duplex ultrasound is a widely available diagnostic method for examining patients with lower limb claudication and pathological ankle-/toe- brachial index or pulse volume recording with or without exercise. Knowledge of characteristic sonographic findings suspicious about large vessel vasculitis is essential for a differential diagnosis of vasculitis versus atherosclerosis. In addition to clinical and laboratory findings, further imaging techniques, e.g. contrast-enhanced computed tomography, magnetic resonance imaging or a combination of positron emission tomography and compu...
