Abstract:
In 14 patients with 19 coronary artery saphenous vein by-pass grafts (ACVB), computed transmission tomography has been performed the day before selective coronary angiography. Non-dynamic, contrast-enhanced sequential scans at 8-mm intervals were obtained starting at the cranial clips, ending at the left ventricle. CT scans were interpreted without knowledge of the catheterisation results. Sensitivity of this technique is 88%. Out of 17 ACVB patent by catheterisation, 15 ACVB are patent by CT. One occluded ACVB to the right coronary artery was thought to be patent by CT scan. This non-invasive technique shows promise as a method to follow up patients after ACVB-grafting.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
