In 100 Korean patients with anterior cerebral artery (ACA) territory infarction, these investigators analyzed the distribution of infarcts within the brain, underlying vascular lesions, stroke mechanisms, and clinical findings.
Most patients (61%) had intrinsic atherosclerotic lesions within the ACA; 10% had cardiac-origin embolism to the ACA, and 13% had internal carotid artery stenotic or occlusive lesions. In 15% of patients the etiology remained unknown. Among patients with ACA atherosclerosis, many had branch-distribution infarcts and presumed artery-to-artery embolism within the ACA branches.
The most common deficits were motor (91%), followed by hypobulia/apathy (43%), urinary incontinence (30%), sensory deficit (20%), and aphasia (18%…
