Abstract

Partial Anterior Circulation Infarct (PACI) is a type of cerebral infarction affecting part of the anterior circulation supplying one side of the brain.

Partial Anterior Circulation Stroke Syndrome (PACS) refers to the symptoms of a patient who clinically appears to have suffered from a partial anterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.

It is diagnosed by any one of the following

- 2 out of 3 features of

- Higher dysfunction

- Dysphasia

- Visuospatial disturbances

- Homonymous hemianopia

- Motor and Sensory Defects (>2/3 of face, arm, leg)

- Higher dysfunction alone

- Partial Motor or Sensory Defect

If all of the above symptoms are present, a Total Anterior Circulation Infarct is more likely.
