Isolated superior mesenteric artery coarctation refers to superior mesenteric artery coarctation that does not combine with aortic coarctation, but occurs alone. All 7 cases were detected by CT examination. 2 patients were treated with vascular stent implantation, 1 patient was treated with coarctation aneurysm and artificial vessel replacement, and 2 cases did not need special treatment after DSA angiography. In one case, the thrombus was completely formed in the false lumen, and in one case, two ruptures were seen in the proximal and distal parts of the false lumen; in the other two patients, further treatment was abandoned. The exact cause of the development of superior mesenteric artery entrapment is not completely clear, but it is considered to be related to hypertension and atherosclerosis, and the entrapment mostly occurs at the junction of the fixed and migrating parts of the artery, which is considered to be related to the shear force of blood flow in this area. The increase in this disease in recent years is mainly attributed to the popularity of multi-row spiral CT and the increased awareness of it. We believe that there is no need for a blanket intervention in patients with superior mesenteric artery entrapment and that individualized treatment plans are needed after analysis of their lesions. If the thrombus in the pseudolumen is fully formed, or if there is a distal or proximal rupture and the artery is not significantly dilated, these two conditions have less impact on the arterial hemodynamics and have less chance of rupture, and can be treated conservatively with dynamic observation; if there is only a proximal rupture, partial thrombus formation in the pseudolumen and a niche image of the true lumen protruding into the pseudolumen is seen, or if the pseudolumen is significantly dilated and the true lumen is compressed and narrowed, endoluminal treatment or surgery should be considered. Treatment.
