Comparative evaluation of surgical myocardial revascularization using autoarterial and autovenous conduits in patients with coronary artery disease: Hospital outcomes

Objective: to evaluate the hospital outcomes of coronary artery bypass grafting using autoarterial and autovenous conduits. Materials and Methods. We conducted a randomized clinical trial. We used the left internal thoracic artery for bypassing the anterior interventricular branch in both groups. The remaining conduits were either only the radial artery or the radial artery and great saphenous vein (study group) or solely the great saphenous vein (control group). The investigated outcomes were, among others, in-hospital mortality, Type 5 myocardial infarction, cerebrovascular event, respiratory failure, bleeding, cardiac arrhythmias, and acute kidney injury (AKI). Results. A sample of 27 patients was randomly distributed among the study group (n=12) and the control group (n=15). According to the perioperative and early postoperative data, there were no statistically significant differences between the groups, except for the duration of stay on artificial ventilation in intensive care unit: in the study group, it was longer than in the control group: 14 (12; 18) h versus 9.3 (5.8; 13) h, p=0.034. The most common complications were cardiac arrhythmias and AKI. There were no statistically significant differences between groups regarding studied for outcomes. Postoperative hospital stay (expressed as number of bed days) also did not differ statistically significantly between groups. Conclusion. According to our data, in the first days after surgery, the use of the radial artery does not provide significant advantages compared to the use of the great saphenous vein.
