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.

Mentions: In addition to the different appearances of the bowel, CT can show underlying pathologic processes that can impair venous drainage. In SMV thrombosis, the vein may be completely non-opacified or rim-enhanced [Figure 9]. The enhancing rim represents either blood flow around the thrombus or a markedly enhanced and hyperemic venous wall.[12]
