Carotid Artery Stenting in Patients With Takayasu's Arteritis:Early and long-term follow-up results

摘要

Takayasu's arteritis is a chronic inflammatory disease of unknown etiology involving the aorta, major branches of aorta, and pulmonary arteries and leads either stenosis and occlusion of the involved artery or aneurysm formation or both. The clinical course and prognosis are variable according to two major prognostic factors, ie, complications and the pattern of the past clinical course, as well as by ESR. Though the aggressive medical and surgical treatment are required for patients with a major complication and a progressive course, surgical reconstruction entails a high incidence of suture line complications including stenosis or dilatation. Moreover all the vascular lesions are amenable for vascular surgery. Initial reports revealed excellent results of percutaneous transluminal angioplasty (PTA) in patients with Takayasu's arteritis. However the suboptimal results and restenosis have been the main limitations of the PTA. Stenting has some benefits for early elastic recoil of the fibrotic vessels and restenosis as in other large vessels in Takayasu's arteritis or atherosclerosis. We report early and long-term results of two cases of carotid stenting in patients with symptomatic carotid stenosis and Takayasu's arteritis, which revealed variable angiographic results according to clinical courses and recommend that stenting in Takayasu's arteritis may be another treatment modality in inactive Takayasu's arteritis.
