Summary
This study identified rare vascular anomalies, including vertebral artery fenestration and basilar artery duplication, in a large angiogram series. These findings highlight the importance of recognizing these variations in cerebrovascular imaging.
Area of Science:
- Neurology
- Vascular Anatomy
- Radiology
Background:
- Cerebrovascular anatomy includes the vertebral arteries and basilar artery, crucial for brain blood supply.
- Vascular variations can impact diagnostic interpretations and clinical management.
- Understanding rare anomalies is essential for accurate neuroimaging.
Observation:
- A review of 75 fixed brains and 2086 vertebral angiograms revealed four cases of unusual vascular formations.
- Two cases of vertebral artery fenestration and two cases of partial basilar artery duplication were identified.
- These anomalies occurred in patients with varying demographics and clinical presentations.
Findings:
- One case showed basilar artery fenestration at the vertebral artery junction without associated disease.
- Another case presented with partial basilar artery duplication in the upper segment.
- Two cases involved fenestrations in the intracranial and extracranial portions of the vertebral arteries, respectively.
Implications:
- These rare vascular variations, including fenestrations and duplications, have significant embryonic and developmental origins.
- Accurate radiological identification of these anomalies is critical for surgical planning and understanding potential complications.
- The study contributes to the literature on cerebrovascular malformations and anatomical variations.
