This study investigate CT images of patients with spontaneous isolated superior mesenteric artery dissection (SISMAD). The investigators also further analyze the CT morphological differences between different options, aiming to determine "alarming CT character" during initial conservative treatment.
57 Patients with SISMAD from Oct 2011 to Jan 2018 in investigator's hospital were included in this research. The investigators collected relevant clinical data and further investigated the CTA characters of both true lumen and false lumen. SMA angle, distance between entry site of dissection and SMA root were also measured.
