This case report describes a patient with non-occlusive mesenteric ischemia that developed due to diabetic ketoacidosis. We believe that early diagnosis and intervention may improve the prognosis of non-occlusive mesenteric ischemia that has low vascular risk, with the major risk factor being dehydration due to diabetic ketoacidosis.

Acute aortic dissection combined with cardiac tamponade is fatal. The radical treatment is an aortic replacement; however, the risk is high. The treatment method for elderly patients is difficult to determine. We suggest conservative treatment with pericardial drainage may be one of the treatment options in the elderly with comorbidities.
