Abstract

Highlights

Over the past twenty-three years, coil embolization has emerged as an effective and minimally-invasive neuro-radiological treatment of intracranial aneurysms
Does coil embolization allow for the treatment of intracranial aneurysms that are unamenable to surgical clipping and allows patients to avoid risks associated with the neurosurgical approach with 4% morbidity and 1% mortality even in elective cases [1]
Coil embolization is not without its own set of potential complications, and ophthalmic complications are rare adverse events that may result from embolic events or ischemia secondary to direct compression and neurovascular compromise [2,3,4]

Summary

Introduction

Over the past twenty-three years, coil embolization has emerged as an effective and minimally-invasive neuro-radiological treatment of intracranial aneurysms. We report a case of delayed inferior branch retinal artery occlusion and transient partial oculomotor nerve palsy of the right eye after coil embolization and balloon occlusion of a giant intracavernous right internal carotid artery aneurysm. A partially-thrombosed giant aneurysm, measuring 4.7 x 4.1 x 3.5 cm, involving the cavernous portion of the right internal carotid artery (ICA) was seen on neuroimaging (Figures 1 and 2).
