Superficial Temporal Artery To Middle Cerebral Artery Anastomoses in the Sylvian Fissure: Case Report

Abstract

An anastomosis between the superficial temporal artery (STA) and the superior trunk of division of the middle cerebral artery (MCA) resulted in significant clinical improvement and normalization of the impaired cerebral blood flow. Possible indications for this type of anastomosis and microanatomical data from the proximal MCA are discussed.

Duplicated middle cerebral artery

“…Gibo et al described a patient who had both a duplicated and an accessory MCA in which the duplicated artery was distributed to the temporopolar, anterior, and middle temporal areas 23. Umansky et al reported a case in which the main MCA irrigated the frontal and parietal lobes, while the duplicated MCA provide blood supply to the temporal lobe 10 , 11. Komiyama et al affirmed that the DMCA consistently reached the temporopolar, as well as the anterior and/or middle temporal territories 20.…”

“…Komiyama et al affirmed that the DMCA consistently reached the temporopolar, as well as the anterior and/or middle temporal territories 20. Hence, the cortical areas supplied by the DMCA are similar to the early branches of the MCA, although the extent of vascular supply may vary 10 , 11 , 20 , 24 – 26…”

“…Anomalies of the MCA occur less frequently than those of other major intracranial arteries 2 , 10 , 11. The incidence of DMCA is reported in necropsy studies and on angiography to be 0.7–2.9%1 , 12 and 0.24–1.5%,13 – 15 respectively.…”
