Summary
A brain aneurysm in the basilar artery was successfully treated using a rare endovascular approach through a persistent primitive trigeminal artery (PPTA). This innovative technique was necessary due to hypoplastic vertebral and basilar arteries.
Area of Science:
- Neurology
- Vascular Surgery
- Interventional Radiology
Background:
- Saccular aneurysms of the basilar artery present significant treatment challenges, particularly when associated with complex vascular anatomy.
- A persistent primitive trigeminal artery (PPTA) is a rare congenital vascular anomaly that can influence cerebrovascular treatment strategies.
Observation:
- A case of a right basilar-superior cerebellar artery saccular aneurysm was identified.
- The patient's vertebral arteries and the basilar artery proximal to the PPTA junction were hypoplastic, complicating standard endovascular access.
Findings:
- Successful endovascular occlusion of the aneurysm was achieved using Guglielmi detachable coils.
- A microcatheter was navigated through the persistent primitive trigeminal artery (PPTA) to access and treat the aneurysm, bypassing the hypoplastic segments.
Implications:
- This case demonstrates the feasibility and success of endovascular treatment of basilar artery aneurysms via a PPTA.
- This approach offers a potential alternative for managing complex intracranial aneurysms in the presence of challenging vascular anatomy.
- Highlights the importance of advanced microcatheter techniques in neurointerventional procedures.
