- Abstract
- Infarct limited to the pial branch territory of the middle cerebral artery(IPBMCA) is a common entity of cerebrovascular diseases. Atherothrombosis of middle cerebral (MCA) or internal carotid artery (ICA), and cardiogenic embolism are presumed causes of this type of cerebral infarct.
Thirty-three patients with acute IPBMCA were systematically studied with brain CT,
MRI, electrocardiography, blood tests, echocardiography, and in selected cases with
angiography or MRA. Hypertension(58%) and heart disease(37%) were common risk
factors, and previous episodes of TIA were present in 27%. Half of the patients
undergoing angiography revealed stenosis or occlusion of MCA, and evidence of carotid
disease was found in 39% of patients with large-artery disease(LAD). Presumed causes
of infarct were LAD in half and cardioembolism in one-fourth. Multiple combinations of
motor weakness, hypesthesia, visual field defect and aphasia or hemineglect were the
clinical presentation. Motor weakness was frequent(91%), and involvement of the f ace,
arm and leg was the most common pattern. In our study, atherothrombosis of MCA
itself is presumed to be the leading cause of IPBMCA in Korea, but cardioembolism,
artery-to-artery embolism from proximal ICA, and occlusion of ICA are also supposed
to contribute to the pathogenesis of IPBMCA.
