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 had 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.

For more information, see stroke.
