Hollow Viscera Manifestations Splanchnic vasoconstriction secondary to sympathetic activation is a major response to hypovolemia. The reduced perfusion to the bowel results in inadequate oxygen delivery thus altering bowel wall permeability increasing leakage and of fluid. Along with replacementofa depleted vascular with contrast agent, the increased bowel permeability results in group of CT findings consistent with shock bo Figure 9, A and B)[11].Generally, the small bowel is diffusely involved whereas the colon is mostly spared. Thickening and increased enhancement of the small bowel wall are the most frequently encountered findings of shock bowel, whereas dilatation of the lumen with fluid(>2 cm) may also be seen Table 2) [8,12] Recently, the specificity of shock bowel for HSC has been investigated. Ames and Federle[13] reported that, despite shock bowel being one of the most commonly associated signs
