# Innominate artery aneurysm in behcet disease; report of one case

## TL;DR

This paper reports a rare case of an innominate artery aneurysm caused by Behçet disease and highlights the importance of timely treatment.

## Contribution

The paper presents a rare clinical case of extracranial carotid aneurysm in Behçet disease and discusses endovascular treatment options.

## Key findings

- Extracranial carotid aneurysms due to Behçet disease are extremely rare.
- Endovascular stent-graft repair is increasingly preferred to prevent complications.
- Timely surgical or endovascular intervention is critical to avoid irreversible complications.

## Abstract

Behçet disease (BD) is a multisystemic recurrent inflammatory disorder that was originally described as a triad of oral and genital ulcerations with uveitis (Behcet, 1937 [1]). Arterial involvement is the most common cause of mortality in patients with BD. Aneurysms are common among the arterial lesions and affect various arteries, but mostly the abdominal aorta. Vascular lesions are encountered in 7 %–29 % of patients, gravely affecting the course of the disease. Extracranial carotid aneurysms due to Behçet's disease are extremely rare (Bouarhroum et al. (2006) [2]).

Herein, we present a 19 year old man presented with hoarsness due to pressure effect to our outpatient clinic.

Due to findings in the computed angiography, he underwent surgery twice.A 100*8 COVERA-covered stent was deployed at the bifurcation of the brachiocephalic artery. Then a 40*13.5 FLUENCY stent with a 2 cm overlap from the previous stent was deployed.

Further investigations regarding endovascular approach for this rare disease is recommended.

•Arterial involvement is the most common cause of mortality in patients with Behcet disease. However; extracranial carotid aneurysms due to Behçet's disease are extremely rare.•Surgical and endovascular treatment options should be evaluated without delay before a possibly irreversible complication occurs.•To prevent side effects, nowadays, endovascular stent-graft repair has been a modality of choice for some clinicians.
