Abstract

To investigate the cause(s) of infarction in the anterior choroidal artery territory, we studied 31 patients (18 men, 13 women) aged 19-82 (mean 58) years, with infarction in this territory documented by computed tomography. All patients were evaluated within 30 days after infarction and had carotid artery studies (arteriography in 17, duplex ultrasound in 14). Fifteen patients had echocardiography. Risk factors for atherosclerosis were chronic hypertension in 20 patients, smoking in 17, diabetes in 10, age greater than 69 years in eight, and elevated serum cholesterol concentration in three. The percentage of patients with extracranial carotid artery stenosis (four of 31, 13%) and the severity of stenosis (mild in two, moderate in two) were similar to that reported in neurologically asymptomatic individuals. The percentage of patients with intracranial carotid artery stenosis (one of 17, 6%) or potential cardiac sources of emboli (two of 31, 6%) was also low. Our findings suggest that infarctions in the anterior choroidal artery territory usually result from small-vessel disease. Associated carotid artery stenosis and potential sources of cardiac emboli are rare and may be coincidental.
