Unibody Endografts for Abdominal Aortic Aneurysm Repair Reduce Radiation and Nephrotoxic Exposure Compared with Modular Endografts

The overall EVAR procedural duration, fluoroscopy time, and volume of contrast medium infusion were significantly reduced in the group treated with the unibody endografts. These results seem to suggest that the unibody endograft may reduce patient risk of nephrotoxic action of the contrast medium, especially important in patients with existing renal insufficiency, and may reduce ionizing radiation exposure for both the patients and operators.
