Endovascular Repair of Bilateral Internal Mammary Artery Aneurysms in a Patient with Marfan Syndrome-A Case Report.

Marfan syndrome (MFS) is an autosomal dominant condition that is caused by abnormal synthesis of connective tissue. The syndrome classically affects the ocular, musculoskeletal, and cardiovascular systems. The most common cardiovascular manifestations include mitral valve prolapse/regurgitation and aortic aneurysms at high risk of rupture and dissection. However, internal mammary artery (IMA) true aneurysms are rarely reported. In this case report, we describe a 43-year-old male patient with MFS and three previous thoracotomies referred for endovascular repair of bilateral IMA true aneurysms. To the best of our knowledge, there are no cases of endovascular treatment of bilateral IMA true aneurysms reported in the literature.
