ABSTRACT
A comparison was made of the three-dimensional CT angiography (3D-CTA) images of four grafts (IMPRA, Bionit, GELSOFT, and saphenous vein). All patent grafts were visualized by 3D-CTA, and opacification of the graft interior was noted in all cases on transverse sections of CT. Occluded GELSOFT and saphenous vein grafts could not be visualized by 3D-CTA. In spite of occlusion, IMPRA and Bionit were visualized by 3D-CTA. However, opacification of the graft interior could not be noted on transverse sections of CT. Confirmation should be made of the following 1. distal portion of native artery shown on 3D-CTA, 2. recognition of opacification (high density) of graft interior on transverse sections of CT. When the CT threshold changed, occluded IMPRA and Bionit showed spotty images. This phenomenon should facilitate accurate diagnosis.
