CT manifestations of small bowel ischemia due to impaired venous drainage-with a correlation of pathologic findings

View Article: PubMed Central - PubMed

ABSTRACT

Acute abdominal pain may result from a wide variety of medical and surgical diseases. One of these diseases is small bowel ischemia, which may result in a catastrophic outcome if not recognized and treated promptly. Computed tomography (CT) by its faster image acquisition, thinner collimation, high resolution, and multiplanar reformatted images has become the most important imaging modality in evaluating the acute abdominal conditions. In this article, the author presents a description of the histology of the small bowel, pathophysiology of small bowel change, and a correlation of the pathologic and CT findings of the small bowel injuries due to impaired venous drainage. A convincing correlation of the microscopic mucosal condition with the enhancement pattern of the thickened small bowel wall on CT is useful in definitely describing the mucosal viability.

A 23-year-old woman with polyposis-induced intussusception. Mesenteric vessels and fatty tissue are clearly seen in the bowel lumen. The thickened submucosa is either covered by normally enhancing, viable mucosa (arrow) or poorly enhancing, necrotic mucosa (arrowhead) which is invisible. The pathologic specimen showed transmural necrosis

Mentions: Helical and multidetector-row CT can sometimes provide two-dimensional reformatted images to add details regarding the transition site of the obstruction [Figure 11].[36] Intussusception shows protrusion of the intussuscipiens, mesenteric fatty tissue, and vessels into another small bowel segment [Figure 12].
