# Case Report: Endovascular electrothrombosis treatment for carotid cavernous fistula caused by ruptured primitive trigeminal artery aneurysm

## TL;DR

This case report describes a successful treatment of a rare brain aneurysm complication using endovascular techniques.

## Contribution

The novel use of detachable coils and endovascular electrothrombosis for treating a carotid cavernous fistula caused by a ruptured PTA aneurysm is highlighted.

## Key findings

- A successful intervention using detachable coils and endovascular electrothrombosis was achieved.
- The patient experienced favorable outcomes following the treatment.

## Abstract

Aneurysms of a persistent trigeminal artery (PTA) are exceptionally uncommon, and their rupture leading to a carotid-cavernous fistula (CCF) is even more extraordinary. The contemporary management of CCF predominantly revolves around endovascular approaches, with a variety of techniques such as detachable balloons or coils, coil embolization augmented with Onyx adhesive, and stent grafting. Herein, we report a successful intervention in a patient with a CCF instigated by a ruptured PTA aneurysm, employing a combination of detachable coils and endovascular electrothrombosis, yielding favorable outcomes.
