Abstract

Five patients were identified during a 10-year period. Angiography performed for other reasons documented occlusion of the middle cerebral artery (MCA) in all patients. MCA occlusions were located along the stem in all patients. Collateral circulation was variable (good in 2, fair in 2, poor in 1) and did not completely account for the benign state. Anterior cerebral artery collaterals were more consistent than those from the posterior cerebral artery. CTs were negative in 3 patients in the territory of the MCA occlusion; 1 patient had a small frontal infarct, and 1 patient had 2 lacunes in the basal ganglia. No patient had a significant extracranial carotid source of embolism. Three patients had potential cardioembolic sources. Presumably, slowly progressive occlusion of the MCA allows for effective collateral circulation to prevent ischemia, but we were unable to document this feature.
