Abstract
We present two patients who had high grade unilateral carotid artery stenosis and controlateral carotid artery occlusion secondary to active stage of Takayasu arteritis. The patients were presented with hemiplegia and history of transient ischemic attacks and visual disturbances. Despite the administration of high dose systemic corticosteroids, both patients deteriorated clinically and surgery was not preferred. Angiogram of the first patient revealed the occlusion of the right common carotid, right subclavian and left subclavian artery and high grade stenosis (> 95%) of the left common carotid and right vertebral artery. These two stenotic arteries were stented. Angiogram of the second patient revealed the occlusion of the left common carotid and subclavian artery and high grade stenosis (> 90%) of the right common carotid artery. PTA + stenting of the right carotid artery was performed. There were no complications during a follow-up period of 10.5 ± 7 months and control angiograms revealed that all stented vessels were free of restenosis. In conclusion, stent-supported PTA to carotid arteries provides immediate symptomatic relief for patients in the active phase of the disease. Its efficacy in the long term should be investigated.
