Transradial occlusion of giant true aneurysms of the secondary supraaortic branches

Abstract True aneurysms involving the branches of the subclavian arteries are rare clinical entities and often manifest with vague symptoms or incidental findings. Early diagnosis and treatment are imperative to prevent aneurysm rupture, which could result in life-threatening bleeding. Definitive diagnosis is established through computed tomography angiography or magnetic resonance angiography. In this case report, we present two cases: a right internal thoracic artery aneurysm and a right costocervical trunk aneurysm, both of which were successfully treated with endovascular procedures using vascular plugs via transradial access. Transradial access is notable for its lower rate of access-site complications compared to the traditionally used transfemoral access. Consequently, it allows for quicker patient mobilization and discharge. These cases underscore the feasibility and efficacy of endovascular treatment for such aneurysms, providing a safe alternative to surgical intervention. Individualized therapy and adequate follow-up are essential due to the rarity of these conditions.
