Background: Angiography of the coronary arteries is the most noninvasive advanced method of establishing graft patency post-coronary artery bypass grafting. The emergence of multi-slice computed tomography has opened a wide avenue for fast imaging around coronary angiography, with a featured scan time of 0.25 seconds, up to 32-slice detection, and multirow detector arrays, which are very important for quick evaluation.
Methods and Results: This study was a retrospective cross-sectional case series that involved 56 individual patients who underwent CABG in the Erbil Cardiac Center. Clinical and radiological evaluations were carried out to evaluate arterial and venous grafts' patency, considering the sociocultural pattern of the individual, type of conduits used, and patency in relation to multiple risk factors. The patency of arterial grafts was 84.9%, while that of venous was 61.9%. Features like hypertension, diabetes mellitus, exercise, and dietary restriction were shown to have a significantly associated vessel occlusion with a P-value of less than 0.05%.
Conclusion: The results of our study also confirm that arterial grafts have far better patency rates than saphenous vein grafts (SVG) in coronary artery bypass grafts. Contributory factors for graft occlusion are diabetes mellitus, hypertension, double antiplatelet therapy, and smoking habits. There is also suggestive evidence that dietary and exercise modification in the patient orientation program would improve the long-term outcome of patients after CABG.
