11/110. Successful management in the case of mesenteric ischemia complicated with acute type a dissection.We report a case of acute type A dissection with ischemic enterocolitis due to blood flow insufficiency in the superior mesenteric artery. A 67 year-old man, with medicated ischemic heart disease and hypertension, presented to another hospital with chest pain radiating to the back and epigastrium. Contrast-enhanced computed tomography revealed a type A dissecting aneurysm, that extended from the ascending aorta to the left common iliac artery, with a 50-mm diameter in the ascending aorta. Celiac trunk and left renal artery arose from the false lumen, and the superior mesenteric artery (SMA) was compressed by the thrombosed false lumen. Symptoms of acute mesenteric ischemia clearly developed. Then, a large amount of tarry stool (melena) was discharged. First, an emergency saphenous vein bypass was performed from the common iliac artery to the superior mesenteric artery at the orifice of the ileocolic artery where it was free from dissection. Then total arch replacement was performed using cardiopulmonary bypass. The patient's postoperative course was uneventful, and the abdominal symptoms completely disappeared. This case demonstrates that prompt surgical relief of ischemia in major organs is important to save lives in the cases of acute aortic dissection with ischemic complications.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
12/110. Intramural barium in ischemic colitis: a new radiographic finding.Two cases of ischemic colitis are presented, demonstrating a new radiographic finding of intramural dissection of barium. Colonoscopic findings were compatible with that diagnosis. Deep, discrete ulcerations were observed during the healing process. Both patients recovered and prolonged retention of the intramural barium was seen.- - - - - - - - - - ranking = 5keywords = colitis (Clic here for more details about this article) |
13/110. A case of Buerger's disease causing ischemic colitis with perforation in a young male.A case of Bueger's disease causing ischemic colitis with perforation in a 32-year-old male is presented. Abdominal angiography demonstrated occlusion of the vasculature supplying the involved transverse colon. The association of Buerger's disease with ischemic colitis is emphasized.- - - - - - - - - - ranking = 6keywords = colitis (Clic here for more details about this article) |
14/110. Disseminated intravascular thrombosis as the cause of ischaemic enterocolitis.Disseminated intravascular thrombosis was diagnosed in a woman aged 63 years. At autopsy the typical appearances of ischaemic enterocolitis were found, together with thrombi in other organs. This case illustrates the previously postulated connection between intravascular thrombosis and ischaemic enterocolitis.- - - - - - - - - - ranking = 6keywords = colitis (Clic here for more details about this article) |
15/110. Ischemic colitis complicating imipramine overdose and alcohol ingestion. Case report.patients on antidepressant medication are instructed to avoid alcohol because of possible additive effects on cognitive function. An unusual case of colonic gangrene following overdose of imipramine and alcohol is presented.

16/110. Nonocclusive mesenteric ischemia induced by digitalis.BACKGROUND: Nonocclusive mesenteric ischemia is a rare but serious disorder with a high mortality rate; causal factors include cardiac glycosides, digoxin, and digitoxin in addition to severe hypotension, decompensated heart failure, and septic shock. CASE PRESENTATION: We present a patient with digitoxin intoxication who died from autopsy-confirmed ischemic gangrenous colitis. CONCLUSION: Despite the frequent occurrence of intoxication with cardiac glycosides nonocclusive mesenteric ischemia is a rare event. However, it should always be included as a differential diagnosis of diffuse abdominal pain in patients treated with cardiac glycosides.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
17/110. Further evidence for an ischemic origin of perforation of the appendix in the neonatal period.A full-term baby girl presented on the 14th day of life with an appendiceal abscess on a basis of appendicular perforation. Pathologic examination found focal transmural coagulation necrosis suggesting an ischemic origin for the perforation. It is argued that appendiceal perforation in the newborn period is a different disease entity than appendiceal perforation later in life. In the newborn, ischemia seems to be the leading pathogenetic factor, and neonatal appendiceal perforation seems, therefore, related to neonatal necrotizing enterocolitis.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
18/110. Colonic ischemia associated with naratriptan use.A 54-year-old woman with acute onset of hematochezia and lower abdominal pain proved to have ischemic colitis associated with the use of naratriptan. The diagnosis was established by colonoscopy with biopsy. There were no other obvious risk factors for intestinal ischemia. The condition resolved within 4 days. Because the use of triptans for the treatment of migraine is increasing, health care providers should be aware of their potential for inducing ischemic colitis.- - - - - - - - - - ranking = 2keywords = colitis (Clic here for more details about this article) |
19/110. An unusual case of myxedema megacolon with features of ischemic and pseudomembranous colitis.myxedema megacolon is rare; usually, it manifests with abdominal distention, flatulence, and constipation. Herein we describe a 72-year-old man who had intermittent diarrhea, bloating, and abdominal pain for more than a year. Cultures of stool specimens for clostridium difficile enterotoxin were variably positive and negative. Colonoscopic biopsy specimens were thought to be consistent with chronic ischemia. thyroid function tests showed severe hypothyroidism; the patient's symptoms resolved with thyroid hormone replacement. We hypothesize that gross dilatation of the colon, attributed to myxedema, was followed by intestinal ischemia and complicated by recurrent episodes of pseudomembranous colitis. A review of the relevant literature is provided. This unusual manifestation of myxedema should be considered in the differential diagnosis when a patient has diarrhea, bloating, and abdominal pain.- - - - - - - - - - ranking = 5keywords = colitis (Clic here for more details about this article) |
20/110. Pathophysiology and current management of necrotizing enterocolitis.Necrotizing enterocolitis continues to be a common and life-threatening gastrointestinal emergency in the low birth weight infant. Prematurity, ischemia, enteral feeding, and infectious disease have been identified as common risk factors, however the exact cause of NEC other than prematurity is yet to be identified. Good assessment skills by the nurse are imperative, because clinical signs of NEC can be both subtle and catastrophic. Frequent radiographs are essential for the diagnosis of NEC and ongoing assessment of neonates diagnosed with NEC. Radiographs including an abdominal flat plate examination and a left lateral decubitus film to evaluate for free air should be obtained every 6-8 hours in the neonates with Stages II and III NEC.- - - - - - - - - - ranking = 5keywords = colitis (Clic here for more details about this article) |
