Normal and Variant Mesenteric Anatomy

Abstract

The mesenteric vascular supply is a combination of rich collateral networks and commonly encountered variant anatomy. The effect of normal and variant anatomy has implications on pathology, treatment choices, and planning interventions. The goal of this chapter is to review the standard vascular anatomy with details of the potential collateral systems that may be present. Finally, a review of anatomic variants will assist in understanding the implications of abnormal anatomy on treatment for diseases associated with the mesentery.
