Coil embolization of bilateral internal mammary artery aneurysms is durable in a patient with Marfan syndrome

Internal mammary artery (IMA) aneurysms are very rare, have a high risk of rupture, and can cause hemothorax. Here, we report the case of a 33-year-old man with metachronal and bilateral IMA aneurysms. He had Marfan syndrome diagnosed by genetic testing. We carried out endovascular repair with coil embolization. He has survived without additional treatment for 7 years. Endovascular repair of metachronal and bilateral IMA aneurysms is feasible...
