A retrospective study of diagnosis and management of mesenteric vein thrombosis

Background: Mesenteric vein thrombosis (MVT) is an uncommon type of intestinal ischemia associated with significant mortality and morbidity because of its delay in diagnosis. Methods: A retrospective analysis of 9 patients treated surgically for MVT during 1982 to 1997 was performed. Results: Nine patients underwent surgical therapy for intestinal ischemia due to MVT. The most common presenting symptom was abdominal pain with bloody diarrhea in 3 patients; preoperative diagnosis of MVT was suspected in 2. Radiologic tests included plain roentgenograms, computed axial tomography, and ultrasound. Time to surgery ranged from 3 hours to 7 days after admission. All patients underwent resection of infarcted bowel with primary anastomosis and immediate postoperative anticoagulation. No patient underwent a second-look operation. The postoperative morbidity and mortality rates were 55% and 11%, respectively. Conclusion: Diagnosis of intestinal ischemia from MVT is often delayed, and strong clinical suspicion and aggressive treatment are necessary in its management. (C) 2001 Excerpta Medica, Inc.
