Vessels Supply and Typical Stroke Findings

Anterior Cerebral Artery (ACA) supplies

Medial frontal and parietal lobes, anterior corpus callosum, parts of the internal capsule and basal ganglia

ACA Typical Stroke Findings

Contralateral leg-predominant weakness or sensory loss, abulia, impaired initiation, and sometimes urinary incontinence

Middle cerebral artery, MCA supplies

Large lateral portions of the frontal, parietal, and temporal lobes; language cortex in the dominant hemisphere; deep basal-ganglia and internal-capsule branches

MCA Typical Stroke Findings

Contralateral face and arm weakness or sensory loss, gaze deviation, visual-field loss; aphasia if the dominant hemisphere is affected; neglect if the nondominant hemisphere is affected

Posterior cerebral artery, PCA supplies

Occipital lobe, inferomedial temporal lobe, thalamus and related structures

PCA typical Stroke findings

Contralateral homonymous visual-field loss, memory problems, visual-recognition deficits, or thalamic sensory symptoms

Vertebral–basilar system supplies

Brainstem, cerebellum, posterior cerebral regions and parts of the thalamus

Vertebral-basilar system typical Stroke findings

Vertigo, diplopia, dysarthria, dysphagia, ataxia, crossed neurological signs, altered consciousness, or bilateral deficits

Small penetrating arteries supplies

Basal ganglia, thalamus, pons and internal capsule

Small penetrating arteries typical Stroke findings

Lacunar syndromes such as pure motor hemiparesis, pure sensory stroke, ataxic hemiparesis or dysarthria–clumsy hand syndrome

What is the most common cerebral ischemic territory?

MCA

Ischemic stroke

blockage of an artery causes inadequate oxygen delivery and infarction.

Intracerebral hemorrhage

a vessel ruptures and bleeding occurs within brain tissue. Common locations include the deep basal ganglia, thalamus, pons and cerebellum, often related to chronic hypertension or other vascular disorders

Subarachnoid hemorrhage

bleeding into the subarachnoid space, frequently from rupture of an intracranial aneurysm. Aneurysms commonly occur around Circle of Willis branch points, especially near the anterior communicating artery and posterior communicating artery

What is the most common type of stroke

Ischemic
