Endovascular aneurysm repair (EVAR): The endovascular procedure is performed under general or local anesthesia. Following systemic heparin administration, both femoral arteries are punctured using the Seldinger technique and sluices are inserted. The main body of the endoprosthesis is inserted along a guide wire and released via a pigtail catheter directly underneath the renal artery, under angiography surveillance. The main body is released as far as the aperture of the contralateral leg. In the next step, the contralateral leg must be probed. The ipsilateral leg is now released completely. The stent prosthesis must not cover the ostium of the internal iliac artery at this point. The contralateral leg is extended using an endoprosthesis. Before this, the outlet of the internal iliac artery is also angiographically depicted, in order to prevent the ostium from being covered. Next comes a final angiography. The procedure is completed by removing the wires and sluices and closing the puncture sites
