Abstract No. 489 Ultralow contrast dose using catheter-directed computed tomography angiography in patients with renal insufficiency

CT angiography offers excellent anatomic detail necessary for vascular procedural planning including endovascular aneurysm repair (EVAR). However, patients with renal insufficiency are at risk for acute renal failure due to iodinated contrast administration. Catheter-directed CT angiography is a technique in which dilute iodinated contrast is injected into an intra-aortic pigtail catheter during the CT scan. The purpose of this study was to evaluate the safety and efficacy of this technique.
