Abstract:
Objective To investigate the clinical features of internal carotid steal syndrome. Methods The clinical manifestations, CT or MRI, digital subtraction angiography, and blood flow compensation in 6 patients with internal carotid steal syndrome were analyzed. Results Of the 6 patients, 2 had unilateral internal carotid artery stenosis, 4 had severe stenosis (in which 2 were on the left side, 1 was on the right side, and 1 was on both sides). The clinical manifestations of the patients with internal carotid steal syndrome were watershed infarction and transient ischemic attack. Four patients had posterior circulation ischemia and 2 had anterior circulation ischemia. Digital subtraction angiography demonstrated that collateral circulation was established in all the 6 patients. The anterior communicating artery, posterior communicating artery, and pial artery were the common compensatory vessels. Conclusions Internal carotid artery steal syndrome can be presented as anterior or posterior circulation ischemia, and the collateral circulation plays an important role in the compensation.
