Ergotamine-induced limb ischemia is rare and usually results from an accidental overdose. Several agents, including erythromycin and tetracycline, raise serum ergotamine levels and augment its effect. We present a case of acute lower limb ischemia with characteristic angiography findings of diffuse arterial spasm resulting from use of ergotamine and an(More)
We present two cases of subclavian steal syndrome from the ipsilateral vertebral artery (VA) to the subclavian artery (SCA), one with the left VA originating from the aortic arch and the other with the left VA originating very close to the origin of the SCA, proximal to the occluded segment. In both cases, angiographic demonstration of these anatomic(More)
The internal and external carotid arteries are usually considered occluded distal to a common carotid artery occlusion but some collateral vessels may provide blood keeping the internal and external carotid arteries patent distal to the occlusion. Most common communication in such a case is diversion of blood from muscular branches of the vertebral artery(More)
