2/129. 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.- - - - - - - - - - ranking = 1.6keywords = vein (Clic here for more details about this article) |
3/129. 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.- - - - - - - - - - ranking = 0.8keywords = vein (Clic here for more details about this article) |
4/129. 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.- - - - - - - - - - ranking = 1keywords = vein (Clic here for more details about this article) |
5/129. 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.- - - - - - - - - - ranking = 1.2keywords = vein (Clic here for more details about this article) |
6/129. 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.- - - - - - - - - - ranking = 0.2keywords = vein (Clic here for more details about this article) |
7/129. 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.- - - - - - - - - - ranking = 1keywords = vein (Clic here for more details about this article) |
8/129. Superior mesenteric vein thrombosis due to diverticulitis and spontaneous thrombolysis after ilio-cecal resection. A case report.inflammation or infection is one of the major causes of superior mesenteric vein thrombosis. A case of secondary superior mesenteric vein thrombosis is presented, which was identified with enhanced CT. The mesenteric venous thrombosis was due to diverticulitis of the ileum, and ilio-cecal resection was performed. Because no findings of intestinal ischemia were present, thrombectomy was not attempted. After surgery, the patient was followed up by repeated CT scan, and spontaneous thrombolysis without thrombectomy or thrombolytic therapy was exhibited. The present case indicated abdominal inflammation or infection strongly related to the development and regression of mesenteric venous thrombosis.- - - - - - - - - - ranking = 1.2keywords = vein (Clic here for more details about this article) |
9/129. Ultrasonographic detection of portal branches and hepatic vein gas associated with mesenteric artery occlusion: a new finding correlated with patient prognosis?The diagnosis of bowel infarction is still a challenge. In some cases, portal venous gas is an associated feature and in these patients, the prognosis is very poor. We report on our experience with two consecutive cases in which ultrasonography showed gas in the portal venous branches, and also in the hepatic veins in one of them. At laparotomy, advanced bowel necrosis was found, and both patients died within 24 hours. Other cases of portal venous gas associated with bowel infarction have been reported, but this is the first report of gas also being found in the hepatic veins. There may be a relationship between the amount of gas in the intrahepatic veins and the stage of bowel ischemia. Confirmation of this might improve the selection of patients and eliminate unnecessary procedures.- - - - - - - - - - ranking = 1.4keywords = vein (Clic here for more details about this article) |
10/129. Considerations in the management of aneurysms of the superior mesenteric artery.Aneurysms of the superior mesenteric artery (SMA) are rare, accounting for 5.5% of all splanchnic aneurysms and <0.5% of all intraabdominal aneurysms. Previous reports have characterized these aneurysms among splanchnic artery aneurysms. However, these aneurysms are quite different in terms of etiology, presentation, and treatment, and their independent consideration is warranted. We report a patient with a traumatic SMA aneurysms who was successfully treated with surgical resection and distal revascularization. We also present an alternative technique of retrograde aorto-SMA bypass using autologous vein that prevents kinking. Also included is a review of the recent literature as it pertains specifically to SMA aneurysms.- - - - - - - - - - ranking = 0.2keywords = vein (Clic here for more details about this article) |
