Abdominal Aortic Aneurism

Endovascular Aortic Repair (EVAR) is an alternative to open surgery and has the advantage of less trauma, faster recovery, fewer complications and fewer contra-indications. During EVAR, under the constant monitoring of DSA, a folded metal scaffold covered with artificial vascular membrane is delivered into the abdominal aorta through the bilateral common femoral artery approach, and then placed into the aneurysm cavity according to the stent positioning set before operation. The stent is fixed onto the artery wall near and distal to the aneurysm by using the self-expanding property of the metal scaffold and the barb on the bare segment of the scaffold (to withstand the impact of high-pressure blood flow on the aortic wall). Then, the aortic wall of the aneurysm and stent membrane form blood thrombosis and structure, this achieve the purpose of isolating the aneurysm and treating the disease.
