A case of ischemic gastroduodenal disease in a patient who was receiving hemodialysis treatment that was managed by conservative treatment

Diffuse arterial atherosclerosis presenting with acute ischemic gastritis: A case report

BACKGROUND

Ischemic gastritis is a clinically rare disease with high mortality that infrequently reported in the medical literature and under-recognized clinically and histopathologically. Early diagnosis and treatment can only be achieved through upper gastrointestinal endoscopy after symptoms appear.

CASE SUMMARY

A 68-year-old woman with a history of intracranial aneurysm developed dizziness, chest tightness and unconsciousness for 2 d. Computed tomography angiography showed diffuse coronary atherosclerosis, moderate to severe stenosis in the proximal end of the left anterior descending branch, multiple calcified plaques in the proximal end of the circumflex branch and right coronary artery, and mild to moderate stenosis. The patient also developed diffuse atherosclerosis in the splenic and mesenteric arteries, with mild lumen stenosis and atherosclerosis in the abdominal aorta and its branches. Endoscopy showed submucosal congestion and damage of the entire gastric mucosa, of which the fundus and body of the stomach were most seriously affected. The mucosa was swollen, with a deep purple color, surface erosion and dark red oozing blood. Pathological examination showed bleeding and necrosis of the gastric mucosa, with residual contours of the gastric glands, consistent with ischemic gastritis.

CONCLUSION

Ischemic gastritis is a rare disease that may be difficult to diagnose as its symptoms may be similar to those of other gastrointestinal diseases. Diagnosis is usually based on endoscopic and pathological examinations, which show insufficient blood supply to the gastric mucosa leading to mucosal damage and necrosis.

Clinical features and progress of ischemic gastritis with high fatalities: Seven case reports

BACKGROUND

Ischemic gastritis is a clinically rare and highly fatal disease that occurs when the hemodynamics of a patient with vascular risk is disrupted. Early diagnosis and treatment are possible only with upper endoscopy after symptom appearance. We report seven cases of ischemic gastritis and its clinical features, prognosis, and indicators that may help in early detection.

CASE SUMMARY

Of the seven patients, six had vascular risk and five died within 2 wk of diagnosis. Their symptoms included hematemesis and hypotension. Although surgery is a choice for radical treatment, not all patients were tolerant. For such patients, conservative treatment was selected, but all of them died. In contrast, patients who underwent repeat endoscopy showed improved mucosal findings, suggesting that this improvement may not affect prognosis. Some ischemic changes such as wall thickening, mural emphysema, and fluid retention in the stomach were observed before diagnosis through endoscopy and computed tomography (CT). The CT scan can be effective for early detection, and improvement in circulatory failure and aggressive treatment may save the lives of patients with this disease.

CONCLUSION

The characteristic CT findings enable early detection of ischemic gastritis. Early diagnosis increases the chance of survival if early therapeutic intervention and improvement of circulatory dynamics can be achieved in this highly fatal disease.
