# Successful Endovascular Embolization of Bilateral Spontaneous Carotid Cavernous Fistula for a Patient Presenting With Bilateral Vision Deterioration: A Case Report and Literature Review

## TL;DR

A rare case of spontaneous bilateral carotid cavernous fistula was successfully treated with endovascular embolization, preventing serious complications.

## Contribution

Highlights the importance of early diagnosis and treatment of spontaneous bilateral CCF using endovascular embolization.

## Key findings

- Early imaging and treatment are crucial for favorable outcomes in bilateral CCF.
- Endovascular embolization is an effective treatment for spontaneous bilateral CCF.

## Abstract

Spontaneous bilateral CCF is rare and often misdiagnosed. Clinicians should consider CCF in patients with headache, tinnitus, or diplopia without trauma. Early imaging and treatment, such as endovascular embolization, are key to preventing serious complications and ensuring favorable outcomes.
