Abstract
INTRODUCTION: A penetrating aortic ulcer (PAU), which accounts for 2-7% of all acute aortic syndromes, is the ulceration of an aortic atherosclerotic plaque that passes through the internal elastic lamina and into the aortic medium. Although PAUs are frequently seen in the middle and lower descending thoracic aortas, it is rare for them to arise in the ascending aorta. Atherosclerotic vascular illnesses and isolated peripheral arterial illnesses are associated with similar risk factors, such as male sex, advanced age, a history of tobacco use, hypertension, hyperlipidemia, and coronary artery disease. Just 20-54% of people with PAU first exhibit symptoms, suggesting that the condition might sometimes present as an asymptomatic phenomenon. CASE PRESENTATION: A 60-year-old male came to the emergency department due to severe abdominal pain and abdominal contractures, which were diagnosed as mesenteric infarction with a relatively small infarcted intestinal segment. A part of the intestine was resected. Then he was referred to request a cardiac consultation to search for the source of the mesenteric infarction, which turned out to be an embolus. CLINICAL DISCUSSION: The patient was referred to cardiac surgery to perform aortic grafting. CONCLUSION: Aortic ulcer and mesenteric infarction together provide a challenging clinical picture that has to be recognized and treated right away. A high index of suspicion is necessary due to the possibility of fast deterioration, particularly in individuals who have risk factors like arteriosclerosis. Improving outcomes depends critically on early diagnostic imaging and intervention.
