Measurement of Arterioles in Coarctation of the Aorta
In cases of aortic coarctation determinations of the wall-to-lumen ratio were made for the arterioles of the thyroid, pancreas, kidney and periadrenal tissue and compared with those for arterioles from the same organs in control cases. As in primary hypertension, there was, on the average, an increase in the wall-to-lumen ratio in each of the regions studied in the cases of coarctation as compared with the same tissues of the control group. This means that for arterioles of the same wall size the lumen was narrower in the cases of coarctation than in the control cases.
