“Intestinal stroke is a type of ischemic bowel disease, which is commonly seen in acute ischemic colitis or chronic ischemic colitis. Most of the patients who suffer from “intestinal stroke” are elderly and generally have atherosclerosis. They have formed blood clots on the basis of arteriosclerosis, which leads to poor blood flow, drastic reduction of local blood supply to the intestinal wall, and even blockage. If treatment is not timely, it can cause infarction or even perforation of the entire intestinal wall, which is life-threatening. We often hear that atherosclerosis can occur not only in the heart and cerebral blood vessels, but also in the intra-abdominal arterial vasculature, the same lesions can occur. Therefore, the common causes of intestinal blood vessel blockage are narrowing of arteries after atherosclerosis, plaque detachment or resulting in narrowing or blockage of blood vessels. The superior mesenteric artery and the inferior mesenteric artery are the two main blood vessels that supply blood to the intestines. Once the main trunk or major branches of these two arteries are blocked, it will lead to varying degrees of insufficient intestinal blood perfusion, which will continue to result in ischemia or even necrosis of the small intestine or colon. It is worth noting that there are acute and chronic forms of “intestinal stroke”. The sudden onset of severe abdominal pain, diarrhea, blood in the stool, etc. is an acute attack. There are also some “intestinal stroke” occurs unknowingly, this is chronic ischemic colitis, the patient’s abdominal pain is not sudden, but is not occurring once, but the feeling is not very obvious, to the aggravation of the situation to the hospital for examination, part of the people may have appeared intestinal stenosis, fibrosis, etc., the development of which may evolve into intestinal necrosis and intestinal obstruction. As with the treatment of cardiovascular and cerebrovascular diseases, the first choice is to use drugs against atherosclerosis to improve the function of blood vessels throughout the body. The application of vascular protection and anti-atherosclerotic drugs should be accompanied by active treatment of hypertension, heart disease, diabetes and other underlying diseases. “Bowel stroke” and atherosclerosis are closely related, and atherosclerosis and other cardiovascular diseases patients are most sensitive to changes in temperature. Summer and autumn is often “intestinal stroke” of the high season, and suffers from high blood pressure, high blood cholesterol and diabetes in the three high people, especially the elderly is “intestinal stroke” is the most favored object. This kind of people if there is a continuous aggravation of abdominal pain, accompanied by blood in the stool and other symptoms, we should go to the hospital in a timely manner to avoid delays in the condition.
