PURPOSE: Demonstrate the role of endovascular management in the treatment of internal mammary artery (IMA) injuries using transcatheter embolization reviewing our 7-year experience. MATERIALS AND METHODS: Our retrospective analysis of cases consists of a total of 12 patients (8 M and 4 F; mean age 52 years) who underwent angiographic studies and transcatheter embolization for IMA injuries. Causes of vascular injury were divided in high-energy trauma (n = 6), iatrogenic (n = 3) and penetrating injuries (n = 3). Type of trauma, associated injury, imaging findings, treatments and complications were assessed. Imaging findings included active haemorrhage, pseudoaneurysm and focal dissection. RESULTS: Embolization was performed with microcoils in all patients; complete thrombosis was obtained in four patients by additional injection of Spongostan pledgets and in two patients with 300-500 μm particles. The technical success rate was 100%. No patient died as a direct result of vascular injury; one died of myocardial contusion and one for severe multiorgan failure related to high-energy trauma. No major and minor complications were registered. No patient required emergency surgery or subsequent surgical treatment. CONCLUSION: Transcatheter embolization offers an effective, efficient and safe alternative to conventional surgical management of IMA injuries.
