Coronary-carotid artery collateral formation in Takayasu's arteritis: First reported case in the literature.

ABSTRACT

We present the first case report of coronary-carotid artery collateral formation in Takayasu's arteritis. There was a vasculitic involvement of both subclavian and carotid arteries with critical stenosis; cerebral perfusion was supported with collaterals arising from the mesenteric arteries and coronary artery. <Learning objective: A case of coronary-carotid artery collateral formation in Takayasu's arteritis is presented. Such an angiographic finding has not been reported previously, and this case could be the first description of coronary-carotid artery collaterals development. The learning objective of the article is to evaluate collateral circulation in Takayasu's arteritis from different vasculature including the coronary system.>.
