“…Cholesterol embolism of the cecum is a known complication of retrograde arteriography and is thought to result either from difficult manipulation of a catheter through an atherosclerotic aorta or from forced distention of the aorta by means of contrast material injection (16)(17)(18).…”

“…It has been reported to occur spontaneously and in association with chronic heart disease (5), cardiopulmonary bypass surgery (6), systemic chemotherapy (7), cholesterol embolization (11,12), and aortitis syndrome (13). It has been postulated (5,13) that isolated cecal ischemia may occur because the ileocecal region is a ''watershed area,'' similar to the splenic flexure and rectosigmoid colon.…”

“…In addition to predisposing the cecum to nonocclusive ischemia, the end artery anatomy and poor collateral vessel flow may put the cecum at risk for embolic infarction. Atheromatous emboli are a known cause of isolated cecal infarction (11,12).…”

Colonic ischemia isolated to the cecum is a rare entity. The authors evaluated two patients who underwent computed tomography (CT) because appendicitis was suspected at clinical examination. CT findings were suggestive of isolated cecal ischemia or infarction. Surgical-histopathologic findings helped confirm the presumptive CT diagnoses. Isolated cecal infarction should be included in the differential diagnosis of acute right lower quadrant pain.

“…89 Patients may have other non-specific gastrointestinal complaints, including altered bowel habits, nausea, anorexia, and weight loss. 89 Complications including colonic ulceration leading to pseudo-polyp formation or an inflammatory mass mimicking colon cancer are rare, [92][93][94] while bowel perforation has been reported to develop if atheroemboli cause mesenteric occlusion in the setting of inadequate collateral blood supply. Rarely, bowel obstruction occurs from stricture formation due to prolonged inflammation.…”

Atheromatous embolization is a multisystem disease complicating advanced atherosclerosis. It occurs most often as a complication of angiography, an endovascular procedure or cardiovascular surgery. Atheromatous embolization can present in a subtle manner where it is often under-recognized, or with catastrophic results including myocardial infarction, strake or acute renal failure. It may mimic other disease processes and often goes underdiagnosed and undertreated. A high clinical suspicion is the key to diagnosis. Atheromatous embolization results in significant morbidity and mortality; therefore, early recognition followed by aggressive management may help to prevent end-organ damage and improve overall clinical outcomes. Management strategies should include risk factor modification, prevention of further insults by discontinuing or avoiding predisposing factors, supportive treatment and interventional or surgical approaches to remove the atheroembolic source. Atheromatous embolization is expected to increase as our population ages and the epidemics of diabetes mellitus and obesity increase.
