Abstract
Objective: retrospective study of the function quality of the freshly harvested allografts of GSV implanted into
111 patients at different cardiac surgery interventions.
Material and methods. Comparative analysis of categorical variables was performed using the Chi2 test and
Fisher exact test (in the presence of less than 5 cells). The data in all cases were considered accurate at significance
value of p<0,05. Analysis of the patients' survivability as well as the freedom from negative outcomes
was estimated by Kaplan—Meier method.
Results. In the early postoperative period 9 patients died and in the late — 5. The survival rate for the medium
term dynamic observation at 19 months was 89%. Patients in amount of 42 were tested with imposed 147
distal venous anastomoses (84 auto- and 63 GSV allografts). Dysfunction was observed in 16 anastomosis
with allo- and in 11 with autografts (p=0.049) from which single anastomoses — 12 allo- and 7 autografts
(p=0.189), in sequential anastomoses — 4 allo- and 4 autografts (p=0.266), respectively. Thus, out of 63 GSV
investigated allografts 47 (74.6%) were functioning, and out of 84 autografts — 75 (89%).
Conclusion. In case of the deficiency of plastic material, the use of allografts is possible at single bypass of the
coronary arteries of secondary importance with small distal bed. It is necessary to avoid imposing of sequential
anastomoses, as well as the relatively long bypasses of the allografts in distal circulation of coronary arteries
because of their comparatively high frequency of dysfunction.
