A Rare Case of Axillary Artery Pseudoaneurysm Due to Shoulder Dislocation Treated With Percutaneous Thrombin Injection.

The incidence of combined neurovascular injuries among patients with high-energy shoulder trauma ranges from 27% to 44%. However, the presentation of an axillary artery pseudoaneurysm (PSA) due to shoulder dislocation without an associated osseous fracture is a very rare condition. Moreover, treatment of combined neurologic and vascular injuries of the shoulder remains controversial. Additionally, minimally invasive treatments such as thrombin injection have been mainly evaluated in patients with iatrogenic femoral artery PSAs. Therefore, we aim to report a rare case of axillary artery PSA associated with brachial plexus injury after shoulder dislocation treated with percutaneous thrombin injection.
