Abstract

Background: Bypass or displacement of the supra-aortic (carotid, subclavicular) arteries is a routine technique in hybrid surgery for complex lesions of the thoracic aorta. The vertebral artery is the first lateral branch of the left subclavicular artery, small but recommended for conservation in hybrid surgery. In the event of an anatomical abnormality - such as the left vertebral artery stemming directly from the cross of the aorta, how should it be treated. The objective of the report is to propose an indication and technique to re-establish vertebral artery circulation if having anatomic abnormality in hybrid surgery for thoracic aortic pathology. Method: The study describes three clinical cases - aortic cross injury and pathology with an abnormality of the left vertebral origin location treated with endovascular intervention and revascularization of the vertebral artery into the left carotid artery. Results: No complications related to surgery and very good circulation of the vertebral artery were observed on postoperative screening CT-scan. Conclusion: Although the indication is controversial, revascularization of the left vertebral artery into the left carotid artery is a safe and beneficial technique for patients, and can be routinely performed at Viet Duc University Hospital.
