Percutaneous Endovascular Aortic Aneurysm Repair with INCRAFT Endograft Guided by CO(2) Digital Subtraction Angiography in Patients with Renal Insufficiency

Iodinated contrast is the most common contrast agent used during endovascular abdominal aneurysm repair (EVAR). However, its use may worsen kidney function in patients with renal insufficiency. Previous studies have demonstrated the safety and effectiveness of carbon dioxide (CO(2))-EVAR. Here, we report cases of three male patients with mild renal insufficiency (mean age: 79 years) that successfully underwent CO(2)-EVAR using INCRAFT ultra-low profile endografts. CO(2) angiography provided the necessary vascular roadmap for safe and effective percutaneous EVAR, eliminating the need for iodinated contrast media and preventing contrast-induced nephropathy.
