Abstract: Objective To evaluate the feasibility of endovascular aortic repair (EVAR) under local anesthesia without using any contrast agent for abdominal aortic aneurysm in patients with high allergic risk to contrast agent.Methods Under local anesthesia and with no use of any contrast,percutaneous EVAR was performed in a patient with abdominal aortic aneurysm who carried high allergic risk to contrast agent.Results Percutaneous EVAR was successfully accomplished.Postoperative follow-up MRI examination showed that the abdominal aortic aneurysm was completely isolated with no endoleak.The blood flow was unobstructed in the covered stent,and bilateral renal arteries were well visualized.Conclusion For the treatment of abdominal aortic aneurysm in patients who are highly allergic to contrast agent and who have contraindications to general anesthesia,percutaneous EVAR performed under local anesthesia and using no contrast agent is safe and effective.Strict observation of indications and sufficient preoperative evaluation of clinical conditions is the key to ensure a successful operation.
