Studies on the relationship between the number of arteriae rectae of intestinal artery and intestinal length.

In the measurement of the length of preserved intestine after massive resection of the intestine, measurement of the length of intestine as it is at the time of operation may produce a large error when compared to the length of the intestine at normal times. Therefore, attention was paid to the number of arteriae rectae of the intestinal artery and a comparison was made between such number and the length of the intestine at normal times in rats and man. As a result, the conclusion was drawn that the measurement of arteriae rectae of the intestinal artery is useful for the estimation of preserved intestine at normal times.
