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.

Diameters of true lumen
Measure the diameters of patent true lumen in patients with isolated mesenteric artery dissection thrombosis in the false lumen , the distance between entry site of dissection and SMA root (P=0.133), the presence of SMA branch involving (P=0.322) have no difference in different treatment groups
Time frame: up to 6 months
the distance between dissection and SMA root
Measure the distance between dissection and SMA root in patients with isolated mesenteric artery dissection
Time frame: up to 6 months
the angle between SMA root and abodominal aorta
Measure the angle between SMA root and abodominal aorta in patients with isolated mesenteric artery dissection
Time frame: up to 6 months
