AI Article Synopsis
- A male patient experienced symptoms of left conjunctival hyperemia and exophthalmos due to a ruptured aneurysm associated with a rare vascular structure known as the persistent primitive trigeminal artery.
- Cerebral angiography initially indicated a direct carotid-cavernous fistula, but further testing revealed the aneurysm as the actual source of the condition.
- The patient underwent endovascular treatment to trap the persistent primitive trigeminal artery, leading to successful closure of the fistula and resolution of his symptoms.
Article Abstract
We report a male patient with a ruptured persistent primitive trigeminal artery variant aneurysm that resulted in a fistula with the cavernous sinus. He presented with left conjunctival hyperemia and exophthalmos. Cerebral angiography revealed a left direct carotid-cavernous fistula; however, a balloon occlusion test determined that the source was actually a ruptured aneurysm located on the trunk of a persistent primitive trigeminal artery. Endovascular trapping of the persistent primitive trigeminal artery was performed, which resulted in fistula occlusion and symptom resolution.
