Statement of the Problem: The first commercially available covered stent was Corvita®, which was developed in Belgium by Jean Pierre Becquemin. Covered stents have expanded the use of endovascular procedures. The treatment of vascular disease has changed dramatically during the last two decades. They are used mainly for the treatment of traumatic arterial lesions, arteriovenous fistulas or false aneurysms, peripheral aneurysms and, more recently, for the treatment of obstructive vascular disease of the aortoiliac and femoropopliteal sectors.To treat visceral artery aneurysms (vaas) covered stents can be useful ,when the artery is not so tortuous and the vaas are not intraparenquimal.The major technical limitations to implant it in vaas are severe tortuosity or sometimes small caliber arteries.
