Outcomes after Endovascular Treatment of Symptomatic Patients with Takayasu's Arteritis

We report our experience with endovascular treatment of supra-aortic arteries and follow-up results in patients with Takayasu's arteritis (TA) presenting with neurological symptoms. Of the 20 patients with TA who underwent cerebral angiography for neurological manifestations between May 2002 and May 2009, 12 (11 females, one male; mean age, 39 years; range 31-56 years) underwent endo vascular treatment and evaluated outcome for 21 lesions, including nine common carotid arteries, four vertebral arteries, four subclavian arteries, two internal carotid arteries, and one brachiocephalic artery. Eight patients underwent multiple endovascular procedures for different lesions in single or multiple stages. Mean angiographic and clinical follow-up durations were 34 months (range, 11-79 months) and 39 months (range 11-91 months), respectively. Technical success was achieved for 20 procedures in 11 patients. One procedure failed, with 50% residual stenosis after stenting due to dense calcification of vessel walls. There were no procedure-related complications. Restenosis occurred at two lesions in two patients were treated by re-stenting. Asymptomatic occlusion occurred at two lesions in one patient. Ten patients remained in 0-1 on the modified Rankin scale (mRs) during mean 39 months. One patient, however, had a score of 3 on mRs due to a traumatic contusion during follow-up. One patient died from cardiac failure 36 months after successful angioplasty. Our data suggest that endo vascular treatment of symptomatic supra-aortic lesions of TA is effective and durable in selected patients with neurologic symptoms.
