Intestinal infarction is an obstacle to the normal operation of the intestinal lumen contents, which cannot pass through the intestine smoothly. Intestinal infarction is a serious surgical disorder, and its incidence ranks third among acute abdominal diseases after acute appendicitis and biliary tract diseases. Once intestinal infarction occurs, it can not only cause anatomical and functional changes in the intestinal tract itself, but also lead to systemic physiological disorders. Clinically, abdominal pain, vomiting, abdominal distension and stool closure are the main manifestations of intestinal infarction, which is characterized by complex etiology, variable condition and rapid development, and if not handled properly, the consequences can be serious. So what are the causes of intestinal infarction? What are the causes of intestinal infarction: First, mechanical intestinal infarction: the most common in clinical practice, more than 90% of acute intestinal infarction is due to mechanical factors causing intestinal lumen narrowing or occlusion, resulting in the intestinal contents can not pass. Second, dynamic intestinal infarction: mainly due to disorders in the muscle activity of the intestinal wall, resulting in the intestinal contents can not run, the intestinal wall itself does not have anatomical lesions, dynamic intestinal infarction can be divided into: 1, paralytic intestinal infarction: also known as non-powered intestinal paralysis. 2. Spastic intestinal infarction: it is relatively rare and transient, due to spasmodic contraction of intestinal muscles resulting in narrowing of the intestinal lumen, which causes obstruction due to obstruction of the operation of intestinal contents. Ischemic intestinal infarction: Ischemic intestinal infarction is also called hemodynamic intestinal infarction. Due to the loss of peristaltic force of the intestinal tube due to the obstruction of blood circulation in the intestinal tube, the food in the intestinal lumen cannot run, resulting in obstruction. It is commonly caused by mesenteric vascular thrombosis or embolism.
