Accessory Middle Cerebral Artery

Abstract Objective: An accessory middle cerebral artery (MCA) usually originates between the A1 and proximal A2 segment of the anterior cerebral artery, reaches the sylvian fissure, and supplies the territory of the MCA. This anomaly has been associated with cerebral aneurysms and Moyamoya disease. We report an accessory MCA arising from the A2 segment. Methods: A cadaveric head, fixed in formalin solution and injected with red and blue silicone on its vascular tree to trace intracranial and extracranial vessels, was dissected. Results: An accessory MCA was found arising from the A2 segment of the anterior cerebral artery and feeding the basal and inferior surface of the inferior frontal gyrus. In our specimen, the vessel was associated with intracranial aneurysms at other locations. Conclusion: Although anomalies of the MCA are rare, neurosurgeons must be familiar with such anatomic variations. An accessory MCA can be associated with Moyamoya disease and aneurysms at its junction with the anterior cerebral artery. Patients with this anomaly may, therefore, have an increased risk for developing aneurysms and other neurovascular complications. By obstructing the surgical view, an accessory MCA may increase the difficulty of exposing lesions in the vicinity of the optic chiasm.

✓ An accessory middle cerebral artery was demonstrated in the carotid angiograms of four patients; it originated from the horizontal portion of the anterior cerebral artery, and in two, gave rise to perforating arteries. None of the accessory arteries was associated with an intracranial aneurysm or anomaly of the central nervous system.

Abstract The accessory middle cerebral artery is a rare vascular anomaly of the brain. We describe a case of a ruptured aneurysm at the junction of the accessory middle cerebral artery and the horizontal portion of the anterior cerebral artery. The lesion was demonstrated by angiography and confirmed at surgery. No perforating arteries arising from this accessory artery were found. There have been only four previous reports of aneurysms located at the origin of the accessory middle cerebral artery. The relevant literature is briefly reviewed.

Accessory Middle Cerebral Artery

Abstract The microvascular anatomy of the main trunk and divisions of the middle cerebral artery was studied in 104 unfixed brain hemispheres injected with polyester resin and dissected under the operating microscope. The following anomalies and variations of the middle cerebral artery were found: fenestration (1 case; 1%), located on the first 4 mm of the main trunk of the middle cerebral artery; duplication (1 case; 1%). with vessels arising from the internal carotid artery; accessory middle cerebral artery (2 cases; 2%). originating on the A, segment of the anterior cerebral artery; single-trunk type of middle cerebral artery (4 cases; 4%), with no division of its main trunk; quadrifurcation (4 cases; 4%), in which the main trunk of the middle cerebral artery divided into four secondary trunks. The clinical implications of these anatomical findings are discussed, and photographs of representative specimens illustrate the anomalies.

✓ An anomalous vessel is reported in a patient with an anterior circulation aneurysm. The presence of an accessory middle cerebral artery arising from the postcommunicating segment of the anterior cerebral artery is described. The clinical relevance and possible etiology of the anomaly are reviewed.
