anatomyIntracranial vascular anomalies of the middle cerebral artery (MCA) are relatively infrequent. Anomalies and variations of the MCA have been considered by many investigators in 3 types: accessory MCA, duplication of the MCA, and fenestration of the MCA. Thirty brain hemispheres underw...
Operative Anatomy The MCA is divided into four segments along its course after it emerges from the internal carotid artery (ICA.) MCA branches supply most of the lateral cerebral hemisphere, along with the insula, lentiform nucleus, and internal capsule. The four MCA seg...
