[Three-dimensional reconstruction of electron beam computed tomography angiography for evaluating coronary artery bypass graft patency].

OBJECTIVE
To probe into the value of electron beam computed tomography (EBCT) for evaluating coronary artery bypass graft (CABG) patency follow-up.


METHODS
EBCT enhanced single slice mode (SSM) and flow study were performed in 150 patients. The results of 3-D reconstruction of CABG were correlated with bypass operation records and coronary arteriograms in 7 patients.


RESULTS
318 of 399 coronary bypass grafts including IMA in 87/100(87%) and SVG in 228/296(77%) were patent. The overall patent rate was 79.7%. In 7 patients with 12 coronary bypass grafts, EBCT studies showed graft patency in 7 and occlusion in 5, as were confirmed by conventional graft angiography.


CONCLUSION
EBCT angiography is a noninvasive method that could replace conventional coronary arteriography for CABG follow-up.
