Traumatic Pseudoaneurysm of the Ascending Cervical Artery Treated with N-butyl Cyanoacrylate Embolization: A Case Report and Review of the Literature

Pseudoaneurysms of the thyrocervical trunk and its branches are commonly iatrogenic in nature; however, trauma is often an inciting mechanism. Open surgical repair was considered the main treatment modality until recent advances in endovascular therapy proved to be a viable treatment option. We report a case of a traumatic pseudoaneurysm arising from the ascending cervical artery with an associated arteriovenous fistula (AVF) that was treated using n-butyl cyanoacrylate (NBCA) embolization. The use of a liquid embolysate such as NBCA provided an efficient and effective means of achieving both pseudoaneurysm occlusion and AVF disconnection.
