A 56 year old hypeensive patient is brought to the emergency depament due to left sided hemiplegia. Hemiplegia is most commonly due to occlusion of?

The middle cerebral aeries are the most common site of occlusion resulting in cerebrovascular accident (CVA). The middle cerebral aeries supply the lateral surfaces of the frontal, temporal, and parietal lobes, and the inferior surfaces of poions of the frontal and temporal bones. MCA infarctions are the most common because the middle cerebral aery is essentially a direct continuation of the internal carotid aery. Contralateral hemiplegia affecting the arm and face more than the leg indicates an infarction in the territory of the middle cerebral aery. If the dominant hemisphere is affected, aphasia also occurs.
