Case 1: A Preoperative CT imaging and aneurysm anatomical parameter measurements. The diameter of the right proximal CIA measured 10.2 mm. B Intraoperative angiogram. In the proximal left CIA, a dissection was observed (white arrow). C Two noncompliant 10 mm balloons were simultaneously inflated inside the parallel covered stents. D The final angiogram demonstrated successful deployment of Aegis™ and two parallel covered stents in the right iliac artery. The left IIA was embolized by coils (white arrow). E The cross-sectional image of the two-year follow-up CT scan demonstrated the “eye of the tiger” configuration (white arrow), with no evidence of gutter leaks. F On the same CT scan, the EIA and IIA stents were patent in the right iliac artery
