Gangrenous necrosis of the small intestine due to volvulus!
Intestinal ischemia occur when blood flow to the bowel (intestines) is decreased because of a blood vessel blockage.A volvulus describes the torsion of bowel around its mesentery. Torsion results in narrowing of the lumen at the point of rotation and compromise of the vessels that supply the torted gut, resulting also in a bowel obstruction.The mesentery may become so tightly twisted that blood flow to part of the intestine is cut off, resulting in ischemic bowel with necrosis or gangrene, seen in the image above. Symptoms can vary from severe abdominal pain, nausea and vomiting, to progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed. Necrotic bowel isn’t salvageable, so the surgeon may need to remove a portion of the intestine if tissue death has occurred with the anastomoses of the viable parts and restoration of blood flow.
