Objective  To summarize the advantages and key points of external fenestration in the treatment of aortic dissection involved visceral branch arteries after endovascular aortic repair (EVAR), and to explore the application effect of external fenestration in aortic dissection involved visceral branch arteries. Methods  A patient with abdominal aortic aneurysm resulting in abdominal aortic dissection and involving multiple visceral arteries after EVAR was treated in Center of Vascular and Interventional Surgery, Department of General Surgery, The Third People’s Hospital of Chengdu. The surgical procedure of this patient was summarized, and the current status of total lumen technique in the treatment of such diseases was discussed and analyzed. Results  The operation was successful, and it took only five hours, the intraoperative blood loss was about 100 mL, the patient was kept in ICU for one day and discharged one week after surgery and no serious postoperative complications occurred (such as spinal cord ischemia, liver and kidney insufficiency, infection, lower limb ischemia, puncture pseudoaneurysm, etc.). Aortic CT angiography was reexamined in three months after surgery, and the three-dimensional reconstruction showed that the aortic stent was stable, the blood flow of visceral branch arteries was smooth, and the aortic dissection was well isolated. Conclusion  Endovascular repair of aortic dissection involving branch arteries of important organs can be achieved by external fenestration technique, it is a new treatment for aortic lesions involved visceral branch arteries.
