1/196. Post-traumatic thrombosis of a segmental branch of the inferior mesenteric vein.

    We report the case of man with post-traumatic thrombosis in a segmental branch of the inferior mesenteric vein with secondary venous congestion and ischemia of the sigmoid colon. We discuss the current imaging modalities for diagnosing venous thrombosis and their relative significance.

2/196. Superior mesenteric vein stenosis complicating Crohn's disease.

    BACKGROUND: Superior mesenteric vein stenosis as a consequence of mesenteric fibrosis, causing the development of small bowel varices, is an unrecognised association of Crohn's disease. case reports: Two cases of gastrointestinal bleeding occurring in patients with Crohn's disease, and a third case, presenting with pain and diarrhoea, are described. In all three patients, visceral angiography showed superior mesenteric vein stenosis with dilatation of draining collateral veins in the small bowel. Overt gastrointestinal bleeding or iron deficiency anaemia resulting from mucosal ulceration is common in Crohn's disease, but acute or chronic bleeding from small bowel varices as a result of superior mesenteric vein stenosis due to fibrosis has not previously been reported.

3/196. Gastric intramucosal pH as a monitor of gut perfusion after thrombosis of the superior mesenteric vein.

    Gastric intramucosal pH (pHi) when measured by a tonometer is a simple and minimally invasive method to determine gut ischemia. In a case of severe mesenteric venous thrombosis, we measured pHi intra- and postoperatively over a period of five days. The goal was to monitor improvement or deterioration of gastrointestinal perfusion in the intensive care unit and to perform a second-look laparotomy if the condition worsened. We observed that gastric pHi is a more sensitive parameter for detecting intestinal ischemia than parameters such as arterial pH, base excess, or lactate. This patient's pHi rose continuously, which allowed us to proceed in a conservative way without any further invasive diagnostic interventions. Thus, the application of a gastric tonometer in cases of mesenteric venous thrombosis may help to reduce costs by preventing unnecessary postoperative diagnostic maneuvers such as angiography, computed tomography, or even second-look laparotomy.

4/196. Mesenteric and portal vein thrombosis in a young patient with protein s deficiency treated with urokinase via the superior mesenteric artery.

    A 32-year-old man, who was previously healthy, had acute abdominal pain without peritonitis. Diffuse mesenteric and portal vein thrombosis were shown by means of a computed tomography scan. A protein s deficiency was found by means of an extensive workup for hypercoagulable state. Successful treatment was achieved with urokinase infusion via the superior mesenteric artery without an operation. This represents an attractive alternative approach to treating patients with this disease. The previous standard of operative intervention(1) can now be reserved for complications, such as bowel infarction with peritonitis, or for those patients with absolute contraindications to thrombolytic therapy.

5/196. Idiopathic mesenteric thrombosis following caesarean section.

    Mesenteric venous thrombosis, "the great mimicker", is a very rare disorder in pregnancy and the puerperium, particularly when not associated with any pre-existing thrombophilia or autoimmune states. We describe a patient requiring a resection of 150 cm of gangrenous small bowel after uncomplicated elective Caesarean section. The only risk factor for thrombosis was recovery from an elective Caesarean section, a condition classified by the Royal College of Obstetricians and Gynaecologists as "low risk". death from thromboembolism is the leading cause of maternal mortality and should always be considered with unusual post partum symptoms. early diagnosis of mesenteric vascular occlusion is difficult and recent evidence suggests that elevated GST isoenzyme may be helpful. In all cases of MVT anti-coagulation is the basis of treatment. patients who are not anti-coagulated after surgery have a recurrence rate of 25 per cent compared with 13 per cent of heparinised post-operative patients. As no other pre-existing cause for MVT was found, management was with warfarin for 6 months, the oral contraceptive pill was contraindicated and heparin prophylaxis was recommended for future pregnancies.

6/196. An unusual complication of appendicitis in childhood.

    Mesenteric venous thrombosis has not been reported after an appendicectomy in the pediatric literature. We report on a special and very unusual complication in a girl who presented mesenteric venous thrombosis (MVT) following an appendicectomy for gangrenous appendicitis. The early diagnosis of this entity is vital in order to start the anticoagulation treatment which could allow preservation of bowel viability. The therapy should be continued for a long time to decrease the risk of relapse.

7/196. Mesenteric vein thrombosis secondary to protein s deficiency.

    Mesenteric vein thrombosis is an uncommon condition. Diagnosis is often difficult because of the nonspecific clinical presentation and findings on routine laboratory and radiological evaluation. endoscopy is usually unrevealing. An underlying hypercoagulable state is often present, but protein s deficiency has rarely been implicated. We describe a case in which chronic inferior mesenteric vein thrombosis, with remarkable endoscopic findings, occurred as the initial presentation of type I protein s deficiency.

8/196. Acute mesenteric infarction caused by small vessel disease.

    A case of acute mesenteric infarction caused by small vessel disease is reported. The patient recovered after 2 operations by which extensive bowel-resections were performed. The resected bowel showed intimal hyperplasia and atherosclerosis of the small mesenteric arteries. Since also thrombocytosis and increased platelet aggregation was demonstrated the main cause of thrombosis however is supposed to be hypercoagulability.

9/196. Superior mesenteric venous thrombosis in malrotation with chronic volvulus.

    Malrotation can be difficult to diagnose after the newborn period because of intermittent symptoms and vague clinical findings, but malrotation with midgut volvulus is usually quite striking in its presentation. early diagnosis and surgical treatment are essential to prevent acute ischemic infarction of the bowel, although chronic complications are rare. The authors present an unusual case of mesenteric venous thrombosis secondary to chronic midgut volvulus. A 13-year-old girl presented with an 11-year history of recurrent bouts of abdominal pain evaluated at 3 other institutions without a diagnosis. At the referring hospital, an episode of bilious emesis associated with abdominal pain prompted a computerized tomography scan of the abdomen. This showed a calcified thrombus within the superior mesenteric vein (SMV). At laparotomy, malrotation with chronic 270 degree volvulus was found with evidence of mesenteric venous hypertension. Segmental occlusion was documented on magnetic resonance angiography. SMV thrombosis is an unusual complication of malrotation with chronic midgut volvulus.

10/196. Spontaneous superior mesenteric vein thrombosis (SMVT) in primary protein s deficiency. A case report and review of the literature.

    Superior mesenteric vein thrombosis (SMVT) is an uncommon but important clinical entity that can induce ischemia or infarction of the small and large bowel. It is rare and accounts for 5-15% of mesenteric vascular occlusions. Bowel infarction due to SMVT can present as an acute abdominal disease, requiring urgent laparotomy with resection of the intestinal segment affected. However, the clinical diagnosis of this event remains difficult and invariably requires specific imaging investigations in order to be able to treat the condition as soon as possible. SMVT without bowel infarction can present as persistent, non-specific abdominal pain and nausea with minimal clinical signs, affecting young individuals without any known predisposing disorder, where laparotomy is not an urgent indication. We report a case of a young adult man with SMVT due to a hypercoagulable state (protein s deficiency), in whom an early diagnosis and appropriate anticoagulant treatment prevented any further extension of the thrombotic process and limited the hemorrhagic infarction of the ileum, which simply required a segmental resection.
