Autoarterial grafts for myocardial revascularization and their morphological assesment in coronary heart disease

: A comparative analysis of arterial grafts used for myocardial revascularization has been done. The morphology of arteries, rate and degree of atherosclerotic process were evaluated. 55 thoracic internal arteries, 52 right gastro-epipiolcal arteries, 34 epigastrical inferior arteries have been tested in cadavers of people with signs of coronary heart disease. Arteria thoracica interna appeared to be a vessel with prevalence of elastic elements, while arteria gastro-epiplocia and arteria epigastrica inferior are predominantly muscle-type. Arteria thoracica interna and arteria epigastrica inferior appeared to be rarely affected with atherosclerosis in people under 60 years of age. Atherosclerotic lesions have been found more often in arteria gastro-epiploica without stenotic lesions. In people over 60 years of age the stenotic lesions in arteria thoracica interna and arteria epigastrica are found much more often than in arteria gastro-epiploica. Arteriography should be done in selecting the proper graft for myocardial revascularization.
