Hypothesis

What are the clinical characteristics and outcomes of patients with infarctions in the territory of the posterior cerebral artery compared to those with middle and anterior cerebral artery infarctions?

Conclusion

Lacunar stroke is the main subtype of infarction occurring in the PCA territory, and patients with PCA infarction have a low in-hospital mortality rate.

Supporting Evidence

  • Infarctions of the PCA accounted for 6.8% of all cases of stroke.
  • Lacunar infarction was the most frequent stroke subtype at 34.5%.
  • In-hospital mortality was low at 3.9%.

Takeaway

This study looked at patients who had strokes in a specific part of the brain called the posterior cerebral artery and found that most had a type of stroke called lacunar stroke, which is less severe.

Methodology

This was a single center, retrospective clinical study analyzing data from a stroke registry over 19 years.

Limitations

Not all patients underwent angio MR or CT angiogram to exclude PCA stenosis, which may affect the classification of some infarcts.

Participant Demographics

128 men and 104 women with a mean age of 73.9 years.
