Posterior temporal branch of the posterior cerebral artery

The posterior temporal branch of the posterior cerebral artery is one of the cortical branches of the artery. The branch comes off of the insular part of the artery and connects to the inferior temporal and occipito-temporal cerebral convolutions. The posterior temporal branch of the posterior cerebral artery arises most distantly from the main trunk of the artery. Anomalies in the posterior temporal branch are rare. According to a recent study, less than three percent of all posterior cerebral artery anomalies were associated with the posterior temporal branch. The possible anomalies of the posterior temporal branch of the posterior cerebral artery are duplication, fenestration, early bifurcation, and sharing a trunk with the superior cerebellar artery. The posterior temporal branch of the posterior cerebral artery is in close proximity to the basilar artery, which makes it highly prone to injury. This vulnerability may manifest itself during surgical procedures on basilar apex aneurysms. Extensive knowledge of microsurgical anatomy this area is needed to prevent surgical complications.
