Clinical application of anatomy of blood vessel arches in ileum: Report of 45 cases / 中国医师杂志

ABSTRACT

ObjectiveTo observe anatomy of the blood vessel arches and their blood circulation in the ileum and further establish surgical strategy for preventing excessive tonicity and ischemia of the ileum after anastomosis of the ileum pouch and the anal canal.MethodsThe blood vessel arches were dissected in the ileum of 45 corpses and their blood circulation routes were observed.ResultsThe 2-tier blood vessel arches were found in 2 cases (4％), the 3-tier blood vessel arches in 35 cases (78％), the 4-tier blood vessel arches in 5 cases (11％), and the 5-tier blood vessel arches in 3 cases (7％).ConclusionsUnder the right colic artery, curing the superior mesenteric artery and vein can release the length of the small intestines, prevent tonicity and ischemia of the ileum after anastomosis of the ileum pouch and the anal canal, and supply enough blood to the ileum by the 2 -5 tier blood vessels.
