Single center experience with modified eversion carotid endarterectomy.

Background: Transaortic endarterectomy is a well-described technique for surgical revascularization of orificial atherosclerotic renovascular disease. Adopting this technique to carotid endarterectomy (CEA), modified eversion carotid endarterectomy (MECE), uses a traditional longitudinal arteriotomy that is confined to the bulb. This obviates the need for patch closure, simplifies the procedure, and permits easy conversion to traditional patch closure carotid endarterectomy (PCEA) for technical defects.

Transcranial Doppler ultrasonography of the basilar artery in patients with retrograde vertebral artery flow.

Objective: Reversal of flow in the extracranial vertebral artery secondary to a proximal subclavian/innominate artery stenosis or occlusion is a frequent finding during carotid duplex ultrasonography. The characteristics of basilar artery flow are not well defined in these patients. The objective of this study is to evaluate basilar artery flow in patients with retrograde vertebral artery flow.
