抄録

Spontaneous isolated dissection of a visceral artery is rare. We report here two cases of isolated dissection of visceral arteries. Case 1 was a 57-year-old man and Case 2 was a man of 46, both of whom suddenly experienced severe abdominal pain without signs of peritoneal irritation. A subsequent abdominal CT scan demonstrated dissection of the superior mesenteric artery, and dissection of the celiac artery and its branches, such as splenic, hepatic, and gastroduodenal arteries, respectively. Both patients were successfully managed by conservative medical therapy with antihypertensive drugs without exacerbation. Two years have passed since onset, and there have been no findings of recurrence. There is a possibility of aneurysm formation and relapse, so it is necessary to continue close observation. It has become possible to make a definitive diagnosis of this disease at an early stage due to recent developments in diagnostic imaging. It is considered important always to keep this disease in mind as one of the differential diagnoses of sudden abdominal pain in emergency medicine.
