Brachial artery aneurysms are a rare type of peripheral artery aneurysm. Although surgical intervention is the standard treatment, interventional radiology may be considered for high-risk patients, such as older adults.
The patient was a woman in her 80s who was transferred to our clinic with sudden onset of coldness in her right upper extremity. Contrast-enhanced computed tomography (CT) showed an aneurysm with a mural thrombus in the right brachial artery and occlusion of the distal brachial artery. She was diagnosed with acute right upper limb ischemia due to distal embolization of a thrombus originating from a brachial artery aneurysm.
To prevent the progression of ischemia and tissue necrosis in the right upper extremity, stent graft placement and thrombectomy were performed. Eight months after the treatment, contrast-enhanced CT showed stent graft occlusion and migration of its distal end into the aneurysm. Although type Ib and II endoleaks persisted, there was no recurrence of distal embolism in the right upper limb.
