Ischaemic jejunal stenosis complicating portal and mesenteric vein thrombosis: a report of two cases

A major complication of portal and mesenteric vein thrombosis is acute bowe l ischaemia resulting in infarction and requiring immediate resection of th e involved segment. Sufficient collaterals can prevent acute haemorrhagic i nfarction, but bowel stenosis due to chronic ischaemia may develop. We report two cases of ischaemic jejunal stenosis occurring 4 weeks after s uccessful treatment of portal and mesenteric vein thrombosis. Diagnosis of high-grade segmental stenosis of the jejunum was established by contrast me dium radiography of the gastrointestinal tract. After laparotomy and resect ion of the stenosed jejunal segment, both patients recovered well from the operation and were released from hospital, Follow-up examinations revealed an unremarkable state of health. Ischaemic bowel stenosis should be considered in patients with recurring ab dominal pain after mesenteric and portal vein thrombosis. A close follow-up of every patient after treatment for mesenteric and portal vein thrombosis should be carried out to ensure early diagnosis of this complication.
