Anatomical terminology
[edit on Wikidata] |
The ileocolic artery is the lowest branch arising from the concavity of the superior mesenteric artery.
It passes downward and to the right behind the peritoneum toward the right iliac fossa, where it divides into a superior and an inferior branch; the inferior gives rise to the appendicular artery and anastomoses with the end of the superior mesenteric artery, the superior with the right colic artery. It supplies the cecum, ileum, and appendix.
Branches
The inferior branch of the ileocolic runs toward the upper border of the ileocolic junction and supplies the following branches:
- colic branch of ileocolic artery, which passes upward on the ascending colon - from the posterior branch of the inferior branch of the ileocolic artery
- ileocecal (some sources acknowledge this division[1] while others do not)
- anterior cecal artery and posterior cecal artery, which are distributed to the front and back of the cecum
- ileal branch of ileocolic artery, which runs upward and to the left on the lower part of the ileum and anastomoses with the termination of the superior mesenteric artery
- an appendicular artery

- Valva ileocaecalis: preservation during ileocolonic surgery employing a rodent experimental model.
- Wilkinson L, Rodning CB.AbstractExperimental and clinical data suggest that the valva ileocaecalis under neurogenic and hormonal influences, modulates antegrade and retrograde flow of succus entericus. A priori reasoning suggests that this function may influence nutrient absorption by and intraluminal endogenous microbial flora within the ileum. The hypothesis to be tested was, can anatomical and functional integrity of the valva ileocaecalis be preserved during the performance of a right hemicolectomy with reestablishment of intestinal continuity via a cecocolostomy? The methodology involved utilization of Lewis male rats weighing approximately 500 gm. General anesthesia was induced for all procedures. The animals were randomly assigned to three groups (10 animals/group): (A) sham operation; (B) pericecal dissection (preservation of the arteria et vena ileocolica); and (C) periileal dissection (ligation of the aforementioned vessels). Celiotomy was performed employing standard clean techniques, and was accompanied by a right hemicolectomy and an end-to-end or end-to-side cecocolostomy. Function of the heterotopic valva ileocaecalis was assessed 6-12 weeks post-operatively employing radiographic criteria (fluoroscopic analysis after intraluminal instillation of barium sulfate). Light microscopic analysis was performed subsequent to the radiographic studies. Periileal dissection associated with ligation of the arteria et vena ileocolica uniformly resulted in anastomotic disruption. Pericecal dissection associated with preservation of those vessels resulted in uniform anastomotic integrity, although two animals succumbed secondary to pneumonitis within 5 post-operative days. Radiographic analysis of the heterotopic valva ileocaecalis revealed intermittent antegrade and no retrograde flow of contrast material, which suggested functional integrity. Qualitative light microscopic analysis revealed architectural integrity.(ABSTRACT TRUNCATED AT 250 WORDS)

- Els HJ, Malan FS, Scialdo-Krecek RC.AbstractThe external ultrastructure of the anterior and posterior extremities of the nematodes, Strongylus asini , Strongylus vulgaris, Strongylus equinus and Strongylus edentatus, was studied with scanning electron microscopy (SEM). Fresh specimens of S. asini were collected from the caecum, ventral colon and vena portae of Equus burchelli and Equus zebra hartmannae ; S. vulgaris from the caecum, colon and arteria ileocolica of E. burchelli ; S. equinus from the ventral colon of E. z. hartmannae and S. edentatus from the caecum and ventral colon of both zebras , during surveys of parasites in zebras in the Etosha Game Reserve, South West Africa/Namibia, and the Kruger National Park, Republic of South Africa. The worms were cleaned, fixed and mounted by standard methods and photographed in a JEOL JSM - 35C scanning electron microscope (SEM) operating at 12kV . The SEM showed the following differences: the tips of the external leaf-crowns varied and were fine and delicate in S. asini , coarse and broad in S. vulgaris and, in S. equinus and S. edentatus, closely adherent, separating into single elements for half their length. The excretory pores showed only slight variation, and the morphology of the copulatory bursae did not differ from those seen with light microscopy. The genital cones differed markedly: S. asini had a ventral triangular projection and laterally 2 finger-like projections: in S. vulgaris there were numerous bosses on the lateral and ventral aspects of the cone; in S. equinus 2 finger-like processes projected laterocaudally ; and in S. edentatus 2 pairs of papilla-like processes projected laterally on the ventral aspects, and a pair of rounded projections and a pair of hair-like structures adorned the dorsal aspects.(ABSTRACT TRUNCATED AT 250 WORDS)
