Kimura Y, et al. – This study aimed to evaluate the latest clinical characteristics and optimal treatment strategy of the superior mesenteric artery. Findings revealed no significant difference in mortality of symptomatic superior mesenteric artery (SMA) dissection patients without accompanying proof of bowel ischaemia or aneurysm between interventional treatment and conservative treatment. They observed the necessity for an additional treatment in a minority of patients receiving conservative treatment, however, more frequently than in those receiving endovascular treatment.
