2025年1月18日 · The middle cerebral artery (MCA) is one of the three major paired arteries that supply blood to the brain. The MCA arises from the internal carotid artery as the larger of the two main terminal branches (the other being the anterior cerebral artery), coursing laterally into the lateral sulcus where it branches to perfuse the cerebral cortex.

2023年4月3日 · The middle cerebral artery (MCA) is the most common artery involved in acute stroke. It branches directly from the internal carotid artery and consists of four main branches: M1, M2, M3, and M4. These vessels provide blood supply to parts of the frontal, temporal, and parietal lobes of the brain, as well as deeper structures, including the ...

The middle cerebral artery (MCA) is one of the three major paired cerebral arteries that supply blood to the cerebrum. The MCA arises from the internal carotid artery and continues into the lateral sulcus where it then branches and projects to many parts of the lateral cerebral cortex .

2023年11月3日 · The middle cerebral artery (MCA) is a terminal branch of the internal carotid artery and is part of the anterior cerebral circulation. The MCA supplies many deep brain structures, the majority of the lateral surface of the cerebral …

2023年7月24日 · The largest terminal branch of the internal carotid artery, the MCA divides into four main surgical segments, denominated M1 to M4. The M1 segment extends from the ending of the internal carotid artery, perforating the brain up to its division. The M2 segment bifurcates or occasionally trifurcates.

Middle cerebral artery (MCA) dissection is a rare cause of ischemic stroke, especially in the M2 or M3 segments. 1 High-resolution 3T magnetic resonance imaging (HR-MRI) can be used to assess the walls of intracranial blood vessels, helping to identify dissection. 2 We herein report a case of M2 segment dissection of the MCA with typical ...

2023年7月10日 · In this study, we aimed to analyse the anatomical distribution and the clinical impact of MCA-M2 occlusions and its subsequent affected CB of the downstream territories in AIS patients both in patients with and without EVT.

2021年10月28日 · 大脑中动脉（mca)是颈内动脉两个终支中较大的血管，缺血及梗塞最常累及此区。 大脑中动脉（MCA）在解剖上一般分成4段或5段，Ml=水平段，M2 =脑岛段，M3=岛盖段，M4、M5合称为终末段或皮层支。

The insular part (M2 segment) of the middle cerebral artery extends anteriorly on the insula, this segment in known as the insular segment. It is also known as the Sylvian segment when the opercular segments are included.
