“Mesenteric venous thrombosis is caused by impairment of venous return of the bowel due to local blood coagulation. Primary mesenteric venous thrombosis is considered spontaneous and idiopathic, whereas secondary mesenteric venous thrombosis is due to an underlying condition. Mesenteric venous thrombosis can lead to venous engorgement and mesenteric ischemia and accounts for 5 to 15 percent of mesenteric ischemic events.”

“If intestinal infarction is impending or peritoneal signs are present, urgent surgical consultation is warranted. The standard surgical intervention includes exploratory laparotomy with possible bowel resection with or without immediate re-establishment of bowel continuity, depending on the amount of peritoneal contamination and the patient’s hemodynamic stability. Second look laparotomy may be required before final abdominal wall closure to assess bowel for continued ischemia further. Efforts are made to conserve as much bowel as possible.””If intestinal infarction is impending or peritoneal signs are present, urgent surgical consultation is warranted.
