# Emergency Artery Ligation and Distal Revascularization for a Limb-Threatening Brachial Artery Mycotic Aneurysm Rupture

## TL;DR

A rare case of a ruptured brachial artery aneurysm in a drug user required emergency surgery to save the limb.

## Contribution

Presents a rare clinical case requiring emergency revascularization for a ruptured mycotic aneurysm.

## Key findings

- Ruptured brachial artery mycotic aneurysm presented with limb-threatening bleeding.
- Emergency revascularization was performed to preserve distal limb perfusion.
- Collateral circulation was insufficient in this case, necessitating immediate surgical intervention.

## Abstract

Brachial artery mycotic aneurysms are very rare and even more uncommon to present initially with bleeding or rupture. Initial presentation of ruptured brachial artery mycotic aneurysm in an active intravenous drug abuser is managed with brachial artery ligation with an option of revascularization later. Distal circulation is not commonly threatened as there is a presence of collaterals to perfuse the distal limb. In this case report, we present a case of limb-threatening brachial artery mycotic aneurysm rupture that needed emergency revascularization surgery.
