PTFE patching to prevent anastomotic aneurysm formation in Takayasu's arteritis.

Takayasu's arteritis (TA) is a chronic inflammatory disorder of uncertain etiology primarily affecting the aorta and its main branches. It is usually seen in women under 40 years of age. The diagnosis of TA is generally based on signs and symptoms of vascular insufficiency such as intermittent claudication, decreased pulses and arterial bruits, and arteriographic findings. Aortic aneurysms and clinical manifestations suggesting cerebral ischaemia require surgery. However, anastomotic aneurysms and graft occlusion of the graft are common complications. Control of inflammation should be achieved prior to surgery and corticosteroid therapy should be continued postoperatively as well. We performed a relatively new surgical technique to reduce the risk of anastomotic aneurysm formation in 2 patients with TA, both of whom had fulfilled the American College of Rheumatology criteria for classification of TA and had symptoms of cerebral ischaemia.
