Summary
This study details three posterior cerebral artery aneurysms. The occipital interhemispheric approach is recommended for P3 and P4 aneurysms, especially with minimal brain retraction.
Area of Science:
- Neurosurgery
- Vascular Neurology
Background:
- Posterior cerebral artery (PCA) aneurysms are rare cerebrovascular lesions.
- Surgical management of PCA aneurysms presents unique challenges due to anatomical location.
Observation:
- Three cases of PCA aneurysms are presented: one in the P3 segment and two in the P4 segment.
- A P3 aneurysm and a P4 aneurysm were treated using the occipital interhemispheric approach.
- A separate P4 aneurysm was addressed via a hematoma cavity.
Findings:
- The occipital interhemispheric approach offers a direct and minimally invasive route for P3 and P4 PCA aneurysms.
- This approach is particularly advantageous for aneurysms associated with minimal brain retraction, facilitating straightforward access.
- Successful clipping and coating were achieved in the described cases.
Implications:
- The occipital interhemispheric approach is a viable and effective surgical strategy for PCA aneurysms.
- This technique may reduce surgical morbidity by minimizing brain retraction.
- Further studies could explore the long-term outcomes of this approach for PCA aneurysm treatment.
