Background Upper extremity arterial aneurysms are a rare, potentially limb-threatening disorder. Due to its rarity, the best treatment modality and outcomes are not entirely established; however, there is a consensus that open surgery is the first-line treatment. We present a complex case of an arterial aneurysm of the subclavian-axillary-brachial axis adequately treated using a hybrid surgical and endovascular treatment. Case Presentation A 59-year-old man presented to the emergency department with acute ischemia of the right upper limb. An extensive thrombosed aneurysm of the subclavian-axillary-brachial axis was identified. The treatment was carried out in two stages. In the first phase, urgent limb revascularization was performed using the great saphenous vein to perform a subclavian-brachial artery bypass. Later, the aneurysm was excluded using a vascular plug and multiple coils. Successful treatment was achieved with no morbidity for the patient. Conclusions Although the gold standard for treating upper limb aneurysms is open surgery, endovascular techniques can be a significant adjunct, reducing treatment morbidity and even mortality.
