Superior Mesenteric Artery Dissection

Completed

• Conditions: Vascular Diseases

• Registration Number: NCT03669380
• Lead Sponsor: Tongji Hospital

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Diameters of true lumen	up to 6 months	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
the distance between dissection and SMA root	up to 6 months	Measure the distance between dissection and SMA root in patients with isolated mesenteric artery dissection
the angle between SMA root and abodominal aorta	up to 6 months	Measure the angle between SMA root and abodominal aorta in patients with isolated mesenteric artery dissection
