Thoracic aortic endografts used to resect the left subclavian artery infiltrated by malignant tumours

Abstract

Endograft placement is a minimally invasive procedure used to repair thoracic aortic aneurysms. This technique is used for treating aneurysms and aortic dissections or ruptures, but it can also be applied for the resection of malignant tumours with vascular invasion. We describe the successful use of the thoracic endovascular aortic repair technique to remove a malignant tumour infiltrating the left subclavian artery in a 50-year-old man. The resection of the left subclavian artery infiltrated by thoracic malignant tumours may require temporary cardiopulmonary bypass, direct clamping of the aorta or extracorporeal circulation techniques. However, the off-label use of thoracic endovascular aortic repair avoids the need for these high-risk surgical techniques. After the surgical removal of the mass and combined aortic resection without complications, the patient was eligible to undergo chemotherapy/radiotherapy, thus improving his prognosis..
