Abstract:
A duplicated middle cerebral artery (dMCA) is a rare anatomical variant that can be associated with aneurysm formation and rupture. The dMCA arises from the terminal portion of the internal carotid artery, with the caudal trunk supplying the temporal lobe and the cranial trunk supplying the frontal lobe and the lenticulostriate perforators. Previous reported cases were all treated with open surgical clipping with or without cerebral revascularization to reconstruct the dMCA. We present a rare case of a young woman with a ruptured dMCA (subtype B) aneurysm. We have demonstrated the unique anatomical relationship among the dMCA, internal carotid artery, and the anterior choroidal artery. Understanding and preserving the dMCA anatomy is essential in such cases to prevent ischemic complications. This was achieved endovascularly by balloon remodeling and coil embolization of the aneurysm in this location.
