Whether or not conservative treatment of superior mesenteric artery entrapment can be cured is mainly related to the severity of the disease, if the disease is mild and does not meet the indications for surgery, the vast majority of patients can achieve more satisfactory results. Superior mesenteric artery entrapment refers to the tearing of the superior mesenteric artery endothelium and midthelium due to various reasons, separation of the endothelium and midthelium, and the inflow of blood, resulting in the division of the lumen of the superior mesenteric artery into a true lumen and a false lumen. Conservative treatment modalities often used for this condition include fasting, gastrointestinal decompression, nutritional support, blood pressure control, improved circulation, anticoagulation and antiplatelet, and blood pressure control therapy. The goal is to prevent further progression of the entrapment and rupture of the false lumen, and to prevent thrombosis to keep blood flow open in the true lumen. The effectiveness and safety of conservative treatment of the disease has been clinically proven. In addition to conservative treatment, endoluminal treatment and surgical treatment are also commonly used. Generally, endoluminal treatment is adopted when conservative treatment is ineffective; open surgery is needed when endoluminal treatment fails, there are obvious signs of intestinal ischemic necrosis, and patients with pseudoaneurysm rupture. In conclusion, patients should listen to the doctor’s advice to take appropriate treatment.
