Summary
This study details a rare carotid cavernous fistula linked to a persistent trigeminal artery, likely caused by an aneurysm rupture. A novel technique using a second balloon stabilized device detachment during treatment.
Area of Science:
- Neurology
- Vascular Surgery
- Interventional Radiology
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.
Observation:
- The case presents an unusual association of CCF with a PTA.
- The fistula's origin was near the carotid origin of the PTA, suggesting a link to aneurysm rupture.
Findings:
- A successful endovascular treatment was performed for this complex CCF.
- A key technical innovation involved using a second, nondetachable balloon to stabilize the primary embolic device during detachment.
Implications:
- This case highlights the importance of recognizing rare vascular associations in neurovascular interventions.
- The described technique offers a potential solution for challenging device deployments in complex CCF cases.
- Further research may explore the specific etiologies linking CCFs and PTAs.
