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.
