One hundred and eighty-four patients included in this study received a total of 331 grafts. The Elipse S/200 Scanner for CT and Siemens Angiotron system for DSA were used for this study. Early in the study, selective coronary angiography were performed and the results were intrepreted in 331 grafts and 86 grafts to evaluate the diagnostic reliability of CT and DSA for graft patency, respectively. While the CT scans correlated with angiographic assessment of graft patency showed 98% of sensitivity, 100% of specificity, and 98% of predicted accuracy, the DSA showed 95% of sensitivity, 100% of specif8city and 95% of predicted accuracy, respectively.
The patency rate in the early postoperated period was 94%, and the cumulative patency rate during follow up of 5 years was 93%, respectively.
In summary, CT and DSA can provide useful information regarding graft patency in the long term follow up of aorto-coronary bypass surgery.
