Summary
A rare type 2 proatlantal artery was found after a cerebral aneurysm rupture in an elderly woman. This vascular anomaly was likely unrelated to the aneurysm rupture, which ultimately led to the patient's death.
Area of Science:
- Neuroscience
- Vascular Anatomy
- Cerebrovascular Diseases
Background:
- Cerebral aneurysms are a significant cause of subarachnoid hemorrhage.
- Anatomical variations in cerebral vasculature can influence surgical outcomes.
- Proatlantal arteries are rare persistent remnants of the embryonic axial artery.
Observation:
- A type 2 proatlantal artery was identified in a 74-year-old female patient.
- The discovery occurred post-rupture of a cerebral aneurysm.
- The patient underwent surgical clipping of the aneurysm and hematoma evacuation.
Findings:
- The patient experienced severe vasospasm and demised 9 days after surgery.
- The identified type 2 proatlantal artery was deemed unlikely to be associated with the aneurysm rupture.
- This case highlights a rare vascular anomaly in the context of a common cerebrovascular event.
Implications:
- Understanding rare vascular variants is crucial for interpreting cerebrovascular events.
- The presence of a proatlantal artery may have implications for blood flow dynamics and surgical planning.
- Further research into the clinical significance of proatlantal arteries is warranted.
