The overall trial results are of only limited help to patients and clinicians in making decisions about surgery. Although endarterectomy reduces the relative risk of stroke by about 30% over the next 3 years in patients with a
Figure 3 Selective arterial angiograms of both carotid circulations in a patient with a recently symptomatic carotid ‘‘near-occlusion’’ (left), and a mild stenosis at the contralateral carotid bifurcation (right). The near-occluded ICA is markedly narrowed, and flow of contrast into the distal ICA is delayed. After selective injection of contrast into the contralateral carotid artery, significant coilateral flow can be seen across the anterior communicating arteries with filling of the middle cerebral artery of the symptomatic hemisphere (top).
