Recently, a patient with a complex superior mesenteric artery occlusion was successfully treated by a new procedure of “stenting the occluded segment of the superior mesenteric artery by open abdominal puncture of the superior mesenteric artery branches”. The patient has been discharged from the hospital and is now able to eat normally. The patient was a male, 59 years old. The doctor found that the superior mesenteric artery was completely occluded from the beginning, and it was impossible to perform stenting of the superior mesenteric artery through the femoral artery by conventional interventional methods. If treated conservatively, not only could the patient’s nutritional status not be improved, but also intravascular mesenteric thrombosis could occur at any time, leading to extensive intestinal necrosis and endangering the patient’s life. If traditional surgery is performed, abdominal aorta-superior mesenteric artery bypass is required, which is prone to hemorrhage, duodenal injury and pancreatic injury. The surgeon boldly proposed to perform “open abdomen, puncture through the superior mesenteric artery branches, and stenting of the occluded segment of the superior mesenteric artery”. The surgeon only made an incision of less than 15 cm in the patient’s abdomen, without blocking the main mesenteric artery and abdominal aorta, and without exposing the root of the superior mesenteric artery and the pancreatic tissue. The operation was completed successfully after about 4 hours. The occluded segment of the superior mesenteric artery was completely opened, with smooth blood flow to all branches and less than 200 ml of intraoperative bleeding. It is reported that this procedure combines delicate vascular surgery techniques with advanced interventional techniques, which greatly reduces the trauma and complications of traditional vascular surgery.
