Brachial artery pseudoaneurysm

Abstract

We describe a case of an elderly man who presented with an upper arm swelling that had developed following a humeral fracture 8 months previously. The swelling was painless but associated with significantly diminished motor function of his right hand and concurrent paraesthaesia. On examination, a large pulsatile mass was identified and CT angiography confirmed the presence of an 11×7 cm brachial artery pseudoaneurysm. The patient underwent surgical repair in which a fragment of the humerus was found to have punctured the brachial artery resulting in a pseudoaneurysm. The patient had an uncomplicated postoperative period and was discharged 2 days later having regained some motor function in his right hand.

Profunda Brachii Pseudoaneurysm following Supracondylar Fracture of Humerus Repair in an 8-Year-Old Boy: A Case Report and Review of Literature

“…Even though it is uncommon, the development of pseudoaneurysms is slow and can cause delayed diagnosis with further possible complications. Pseudoaneurysms, depending on the size, can be asymptomatic or present with symptoms ranging from pressure effect on the adjacent tissues such as pain, swelling, and nerve injury, or ischemic complications due to thrombosis or distal embolization with the management depending on the location, size, and causative pathogenesis of pseudoaneurysm [ 7 , 8 ].…”

“…Therefore, he was transferred to the operating room for the surgical repair of the pseudoaneurysm. On close inspection during surgery, it was found that the sac contained a sharp fragment of the humerus with a single puncture wound in the brachial artery which was the reason for pseudoaneurysm formation [ 8 ].…”

Acute Upper Limb Ischemia Due to Delayed Presentation of a Brachial Artery Pseudoaneurysm Post-Venipuncture

“…Although predominantly described as secondary to iatrogenic causes, patientrelated factors may be considered, such as intravenous drug use or after sustaining a humeral fracture. [8][9][10] Brachial artery pseudoaneurysms 2 cm or less tend to be asymptomatic. 2 When symptomatic, they often present with a pulsating mass and local tenderness.…”

Isolated brachial artery aneurysm successfully treated with a covered stent in a patient with Behçet's disease

“…[7] Isolated aneurysm of the brachial artery in BD has been scarcely reported in the literature with only a couple of cases published in 1988 and 1993. [8,9] Koksoy et al [6] operated 29 aneurysms in BD patients. In their series, all aneurysms appeared to be pseudo-aneurysms.…”
