Summary
A rare unruptured aneurysm of the primitive trigeminal artery (PTA) was successfully treated with bypass grafting and artery clipping. This case highlights effective surgical management for PTA aneurysms.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Cerebrovascular Diseases
Background:
- Aneurysms involving the primitive trigeminal artery (PTA) are rare cerebrovascular malformations.
- Understanding the anatomical variations and hemodynamic factors is crucial for effective treatment planning.
Observation:
- A case of an unruptured aneurysm was identified at the junction of the right internal carotid artery's cavernous segment and the PTA.
- The posterior circulation was independent of the PTA, indicating an adult-type PTA variant.
Findings:
- Successful surgical intervention was achieved using a combination of external carotid artery-anterior temporal artery vein graft bypass, internal carotid artery ligation, and PTA clipping.
- Follow-up angiography confirmed thrombotic occlusion of the aneurysm, indicating successful treatment.
Implications:
- This case contributes to the limited literature on surgically treated PTA aneurysms, with only 11 reported cases including this one.
- The presented surgical strategy offers a viable option for managing PTA aneurysms, guiding future treatment decisions.
