Summary
A rare carotid-cavernous fistula case was successfully treated using endovascular methods. This case highlights the significance of the Saltzman classification for persistent trigeminal artery anatomy in guiding treatment decisions.
Area of Science:
- Vascular Neurology
- Interventional Neuroradiology
- Neuroanatomy
Background:
- Carotid-cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus.
- Persistent trigeminal artery (PTA) is a rare congenital vascular anomaly where the primitive trigeminal artery fails to regress.
- The coexistence of CCF and PTA presents unique challenges in diagnosis and management.
Observation:
- A case of a direct carotid-cavernous fistula (CCF) associated with a persistent trigeminal artery (PTA) is presented.
- The patient's specific PTA anatomy was meticulously evaluated.
- Saltzman classification was utilized to categorize the PTA anatomy.
Findings:
- Successful endovascular treatment of the CCF was achieved.
- The anatomical classification of the PTA according to Saltzman was crucial for planning the endovascular approach.
- Demonstrated the feasibility and efficacy of endovascular techniques in managing complex CCF with PTA.
Implications:
- Highlights the importance of detailed anatomical assessment using classifications like Saltzman for PTA in managing CCF.
- Emphasizes the role of endovascular treatment as a primary therapeutic option for such complex vascular lesions.
- Contributes to the understanding of neurovascular anomalies and their interventional management strategies.
