S ummary .1. An investigation into the pattern of the inferior mesenteric artery and the blood supply to the distal colon is described. 2 The literature relating to the presence and significance of the “critical point” is briefly reviewed. 3. Because it is so infrequent, no reliance can be placed upon the existence of an anastomosis between the lowest left colic and superior hemorrhoidal vessels. 4. The vascular distribution is discussed in terms of the part it plays in the surgery of the pelvic colon and rectum. The importance of the vascular pattern is emphasized in that it ( a ) preserves the vitality of the recto‐sigmoid stump in resection of the pelvic colon, (b) permits effective mobilization of the gut in perineal excision of the rectum with restoration of function.
