Idiopathic internal mammary artery aneurysm

Abstract

Aneurysms of the internal mammary artery are extremely rare, and their presentation and treatment are variable. Since these aneurysms often tend to rupture and cause haemothorax and life-threatening conditions, the knowledge of secure treatment options is indispensable. We here report the case of an idiopathic internal mammary aneurysm in a 46-year-old man. Open surgical resection of the aneurysm was performed in this case without any complications. The postoperative course was uneventful and the patient was in a good physical condition without any vascular or neurological abnormalities during follow-up.

Idiopathic internal mammary artery aneurysm in the setting of aberrant right subclavian artery

“…In the past 15 years, two idiopathic IMA aneurysms were described in the literature and were treated successfully using an open approach with uneventful recovery. 1 , 2 , 3 , 4 , 5 , 6 , 7 The variable presentations of these aneurysms create a diagnostic dilemma. CT angiography and conventional angiography are required to delineate the IMA aneurysm and to plan the appropriate intervention.…”

“…Multiple treatment options are described in the literature (open surgical repair, stent deployment, and coil embolization). 1 , 6 , 7 , 8 The Table summarizes previously reported IMA aneurysms regarding location, etiology, treatment, and outcome. Despite the lack of long-term results, an endovascular approach by coil embolization or stent deployment has become the treatment option of choice because of its minor invasiveness.…”

“…However, open surgical repair is recommended in selected cases (large aneurysms causing compressive symptoms and the need for histologic examination). 7 …”

“… 2 , 3 , 4 , 5 , 6 However, very few case reports describe an idiopathic IMA aneurysm. 1 , 7 These aneurysms have variable presentations, including hemothorax, hemoptysis, and anterior mediastinal mass, or they can be found incidentally. 4 The patient's consent for publication was obtained.…”

“…Development of pseudoaneurysms and true aneurysms of the internal mammary artery (IMA) or its branches are rare and to date <15 cases have been described in the literature [ 1 – 4 ]. Pseudoaneurysms are most often iatrogenic or secondary to trauma.…”
