Superior Mesenteric Vein Thrombosis in Acute Abdomen with Underlying Left Paraduodenal Hernia: An Unusual Intraoperative Finding

Abstract

Internal hernias are rare but an important cause of small bowel obstruction. Understanding embryology as well as surgical anatomy is important in treating such cases. Paraduodenal hernias, the most common among the internal herniations, may present with symptoms of bowel obstruction, incarceration or even may be detected incidentally. They need surgical repair in all cases due to the associated morbidity and mortality. Superior Mesenteric Vein (SMV) thrombosis and bowel ischemia on other hand are surgical emergencies with high mortality and morbidity if not treated in time. We report a case which presented with features of SMV thrombosis and obstruction, which intraoperatively was found to be paraduodenal hernia with a small ischemic segment at jejunum, eliminating risk of larger resection and short bowel syndrome.
