Arch vessel aneurysms (innominate, carotid, subclavian) are the most frequent type in the region. Causes stem from degenerative disease, trauma, thoracic outlet syndrome (TOS), and increasingly, iatrogenic injury from medical procedures. These aneurysms pose significant risks, including rupture, stroke due to clotting, and compression of nearby nerves (causing symptoms like hoarseness or arm weakness) or the esophagus (leading to difficulty swallowing, dysphagia). Their presence often warrants investigation for other aneurysms in the body. Diagnosis heavily relies on advanced imaging like CTA, MRA, and angiography to detail anatomy and aid planning. Treatment options include traditional open surgery (resection and grafting), which is durable but carries higher risks, and the growing field of endovascular or hybrid repair (combining open and endovascular techniques) using stent grafts and bypasses. Endovascular/hybrid approaches often offer lower immediate morbidity, especially for descending lesions and in higher-risk patients, though long-term data is still developing. Aneurysms of an aberrant right subclavian artery (associated with Kommerell's Diverticulum) are congenital but can degenerate, causing symptoms or rupture risk less predictable by size. Their repair is complex, often requiring hybrid methods. More distally, axillary artery aneurysms are commonly post-traumatic or iatrogenic, risking nerve damage; open repair is standard, but endovascular is an option. Brachial aneurysms, frequently iatrogenic pseudoaneurysms from trauma or procedures, can cause nerve compression, with open surgical repair being the primary treatment. Distal aneurysms in the forearm/hand are typically traumatic pseudoaneurysms treated with ligation, reconstruction, or embolization. Management across all types is complex, requiring meticulous planning and often lifelong surveillance.
