Abstract:
Aneurysm of the internal thoracic artery is a rare entity, with variable presentation and a potential risk of fatal rupture. Angiotomography is the diagnostic test of choice and is useful for planning treatment. Considering the morbidity of thoracic access for a direct approach and the unpredictable risk of rupture, an endovascular procedure is the treatment modality of choice for this type of aneurysm. We describe the case of an internal thoracic artery aneurysm discovered incidentally during investigation of syncope and treated by embolization with low-profile and controlled-release microcoils.
