Enterocolitis does not usually lead to Nutcracker syndrome. Nutcracker syndrome, i.e., left renal vein compression syndrome, is a clinical condition caused by compression of the left renal vein as it travels into the inferior vena cava due to a pinched angle between the abdominal aorta and the superior mesenteric artery. Under normal circumstances, the angle through which the left renal vein travels is filled with mesentery, fat, lymph nodes and peritoneum, so that the left renal vein is not squeezed. However, when puberty develops faster, height grows rapidly, the spine is over-extended, the shape of the body changes drastically, or the kidney ptosis occurs, the left renal vein is squeezed in the angle, which leads to the change of blood flow and the corresponding clinical symptoms. Enteritis is a bacterial, viral, parasitic and other causes of small intestinal inflammation and colitis, clinical manifestations are mainly abdominal pain, diarrhea, dilute watery stools or mucous pus and blood stools. Complications of enterocolitis are usually toxic megacolon, colon perforation, intestinal stenosis, and colorectal cancer, and there have been no clinical reports of enterocolitis causing the angle between the superior mesenteric artery and the abdominal aorta to become smaller. In patients diagnosed with Nutcracker Syndrome, nutritional support is recommended, as well as regular rechecks of blood and urine routines and renal vascular ultrasound.
