[Correlation of wall thickness and the luminal diameter of the arterial vessels of the kidneys in hypertension].

The autopsy material was used to study the ratio of the wall thickness and the lumen diameter in arch and interlobular arteries and arterioles of the kidneys in patients with hypertension and in the control group. A statistical analysis revealed in interlobular arteries and arterioles of the age group of 30-49 years a slight but a significant shift of the parameter under study towards more severe degrees of involvement. This was confirmed by the frequency of different degrees of damage. No significant differences in changes observed in interlobular arteries and arterioles were found. This method is recommended for the study of the structural changes of intrarenal arteries.
