Traumatic iatrogenic dissecting anterior cerebral artery aneurysms: conservative management as a therapeutic option

Abstract

Introduction

Traumatic iatrogenic intracranial aneurysms (TICAs) are rare, but are important due to their risk of intracranial hemorrhage and complexity of management.

Methods

Two adult patients, one with history of chronic sinusitis and nasal cavity polyposis undergoing functional endoscopic sinus surgery (FESS), and second during rhinoplasty, suffered subarachnoid hemorrhage (SAH) due to anterior cerebral artery (ACA) injury during the procedures.

Results

Two women patients aged 17 and 38 years with SAH after nasal surgery were referred to our institute. Three small dissecting aneurysms were seen involving A2 segment of ACA of two patients. Both were managed conservatively. Follow-up angiography (after 2 months) demonstrated complete occlusion of the aneurysms. There was no rebleeding and the patients had a good outcome at the last follow-up.

Conclusions

Conservative management of traumatic iatrogenic dissecting cerebral aneurysms is a reasonable therapeutic option that can lead to favorable angiographic and clinical outcomes.
