Common Types of Strokes

Anterior Cerebral Artery Stroke

The ACA supplies the medial frontal and parietal lobes, including the motor strip, as it courses into the interhemispheric fissure. ACA stroke results in contralateral leg weakness.

Middle Cerebral Artery Stroke

The MCA supplies the lateral frontal and parietal lobes and the temporal lobe. MCA stroke results in contralateral face and arm weakness. Dominant-hemisphere MCA stroke causes language deficits. Proximal MCA occlusion causing ischemia and swelling in the entire MCA territory can lead to significant intracranial mass effect and midline shift (see Fig. 41-6).

Posterior Cerebral Artery Stroke

The PCA supplies the occipital lobe. PCA stroke results in a contralateral homonymous hemianopsia (see Fig. 41-6).

Posterior Inferior Cerebellar Artery Stroke

The PICA supplies the lateral medulla and the inferior half of the cerebellar hemispheres. PICA stroke results in nausea, vomiting, nystagmus, dysphagia, ipsilateral Horner's syndrome, and ipsilateral limb ataxia. The constellation of symptoms resulting from PICA occlusion is referred to as lateral medullary syndrome or Wallenberg's syndrome.
