Dynamic Volumetric Computed Tomography Angiography Is a Preferred Method for Unclassified Endoleaks by Conventional Computed Tomography Angiography After Endovascular Aortic Repair.

ABSTRACT: Background The aim of this study was to assess the feasibility and safety of dynamic volumetric computed tomography angiography ( DV - CTA ) for endoleaks detected but not classified by conventional CTA in patients after endovascular aortic repair. Methods and Results From January 2016 to October 2017, 24 patients with endoleaks with aneurysm sac enlargement detected but not classified by conventional CTA were randomly assigned to the conventional CTA group and the DV - CTA group for further evaluation. The amount of contrast agent, radiation dosage, and changes in creatinine during the operation were compared between the 2 groups. Reintervention was performed according to the endoleak classification followed by the 6- and 12-month follow-up. The accuracy of classifying endoleaks by DV - C
