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.
