THE SMALL intestine has a remarkable ability to withstand interruption of its blood supply. The distribution and anastomoses of its vessels appear to be responsible for its great revascularizing potential, and it has been generally assumed that the peculiar arcuate system of the intestinal tract is the chief factor in overcoming vascular deprivations. Considerable experimental effort has been devoted to determining the degree of vascular interruption which is compatible with life, yet the exact mode by which compensation takes place has not been clearly established. The literature pertinent to these studies may be discussed under two categories—(1) anatomic studies and (2) experimental mesenteric vascular interruption and revascularization of the intestine.

ANATOMIC STUDIES  Morphologic reports on the larger vessels of the small intestine are in accord, but many discrepancies appear in descriptions of the vasa recta and the vessels within the intestinal wall. Much of the confusion doubtless arises from the
