Hybrid treatment of recurrent venous mesenteric thrombosis with small intestinal necrosis

The article presents a clinical case of a 39-year-old patient with thrombosis and postoperative rethrombosis of the superior mesenteric vein. The disease was complicated by the small intestine necrosis and abdominal surgical infection. Successful thrombectomy and bowel resection made it possible to restore mesenteric blood supply, to stabilize the patient’s condition and to perform an enteroenteroanastomosis. Due to antithrombin III deficiency, rethrombosis in the early postoperative period was complicated by anastomotic leak, unformed intestinal fistula and peritonitis. A hybrid treatment (surgical, parasurgical and conservative) was performed, which included selective infusion of a thrombolysis activator at the superior mesenteric artery mouth. The patient recovered.Clinical and laboratory manifestations of superior mesenteric vein thrombosis, in contrast to acute circulatory disorders in the arteriomesenteric system, are nonspecific and do not always allow timely diagnosis of intestinal ischemia. MSCT angiography identifies venous mesenteric thrombosis in most cases. The ineffectiveness of anticoagulant therapy against the background of antithrombin III deficiency caused superior mesenteric vein thrombosis and rethrombosis. The treatment of the small intestine critical postoperative ischemia included an increase in the volume of antithrombin III and frozen plasma intravenous infusion and selective administration of a thrombolysis activator (actilyse) into the superior mesenteric artery, which made it possible to restore the arteriolovenular intramural blood flow of the small intestine and to prevent another stem rethrombosis of the superior mesenteric vein. Laparostomy using a silicone plate made it possible to constantly monitor the course of the abdominal infectious process and to make timely decisions about the next intervention if medically required. The vacuum assisted design provided permanent lavage of the abdominal cavity without trauma to the soft tissues of the abdominal wall and presenting intestinal loops.
