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
- Higher dysfunction alone
- Partial Motor or Sensory Defect
If all of the above symptoms are present, a Total Anterior Circulation Infarct is more likely.
