“…Of the four patients for whom arterial and portal phase CT images were available (in addition to tissue samples), three patients (3/4, 75%) showed higher enhancement in portal phase than arterial phase, likely due to fibrosis and submucosal capillary dilatation. The radiographic findings associated with post-ischemic strictures mimicked those of various intestinal diseases such as Crohn's disease, NSAID-induced enteropathy and/or CMUSE ( 4 ). A previous report on strictures associated with Crohn's disease showed that it was relatively uncommon at the time of diagnosis.…”

“…To our knowledge, no study has focused on the radiologic features of post-ischemic strictures. A few cases of postischemic stricture have been identified and clinical findings have mainly been described in case reports ( 4 8 9 10 15 ). The cases in this study highlight several important aspects of post-ischemic stricture.…”

“…A few cases of post-traumatic ischemic strictures and ischemic strictures following surgery have been reported ( 5 6 7 ), as well as ischemic stricture as a result of mesenteric vein thrombosis and ischemic enteritis ( 3 4 8 9 10 ). However, most of these studies focused on clinical findings.…”

ObjectiveTo investigate the characteristic radiologic features of post-ischemic stricture, which can then be implemented to differentiate that specific disease from other similar bowel diseases, with an emphasis on computed tomography (CT) features.Materials and MethodsEight patients with a diagnosis of ischemic bowel disease, who were also diagnosed with post-ischemic stricture on the basis of clinical or pathologic findings, were included. Detailed clinical data was collected from the available electronic medical records. Two radiologists retrospectively reviewed all CT images. Pathologic findings were also analyzed.ResultsThe mean interval between the diagnosis of ischemic bowel disease and stricture formation was 57 days. The severity of ischemic bowel disease was variable. Most post-ischemic strictures developed in the ileum (n = 5), followed by the colon (n = 2) and then the jejunum (n = 1). All colonic strictures developed in the “watershed zone.” The pathologic features of post-ischemic stricture were deep ulceration, submucosal/subserosal fibrosis and chronic transmural inflammation. The mean length of the post-ischemic stricture was 7.4 cm. All patients in this study possessed one single stricture. On contrast-enhanced CT, most strictures possessed concentric wall thickening (87.5%), with moderate enhancement (87.5%), mucosal enhancement (50%), or higher enhancement in portal phase than arterial phase (66.7%).ConclusionPost-ischemic strictures develop in the ileum, jejunum and colon after an interval of several weeks. In the colonic segment, strictures mainly occur in the “watershed zone.” Typical CT findings include a single area of concentric wall thickening of medium length (mean, 7.4 cm), with moderate and higher enhancement in portal phase and vasa recta prominence.

“…There are few case reports of colon stricture formation from various other rare etiologies. These include iatrogenic superior mesenteric artery injury, portal vein thrombosis, NSAID-induced, colonic cryptococcosis, and amebiasis [15][16][17][18]. To the best of our knowledge, this is the first reported case of hepatic flexure stricture attributed to recurrent ischemic episodes in the same anatomical area.…”

Colonic ischemia is the most common form of gastrointestinal ischemia, which frequently affects the elderly population. The diagnosis and treatment can be challenging since it is prevalent in patients who are debilitated and have multiple comorbidities. However, most cases remain undetected until further complications emerge. Some of these patients will develop prolonged complications like chronic ischemic colitis or stricture requiring surgical intervention. Here we present a case of a colonic stricture secondary to recurrent ischemic colitis in an elderly female patient with multiple medical problems.
