Survival of the severely injured trauma victim through aggressive therapy results in new complications. We report the first instance of mesenteric thrombosis in association with penetrating cardiac trauma. Selective visceral angiography should be obtained early in a patient with persistent abdominal pain following a period of prolonged shock; such cases should have a more favorable prognosis if diagnosed early in view of the limited period of cardiac dysfunction and the younger age group.

Three cases of postsplenectomy mesenteric thrombosis, two associated with thrombocytosis, are presented. Experience has shown that persistent thrombocytosis, accompanied by abnormal platelet function, is not a benign condition and may be associated with thrombosis. When encountered, postsplenectomy thrombocytosis of greater than 800,000 per mm-3 must be evaluated by platelet function studies and anticoagulation begun. Post-prandial cramping abdominal pain may be an early symptom of thrombosis, demanding immediate anticoagulation. Low-dose heparin, ASA, and dipyridamole are three of the more commonly used treatment modalities. Small bowel resection is indicated if thrombosis occurs.

We report on the case of a young lady on oral contraceptives for only 1 month who experienced severe central abdominal pain of a progressive nature. Mesenteric vein thrombosis was diagnosed by ultrasound and confirmed by magnetic resonance imaging. The patient was treated initially with streptokinase followed by heparin and warfarin with subjective improvement, and gradual disappearance of the thrombus was observed on ultrasound and magnetic resonance imaging. In this report we wish to emphasize the feasibility of the early diagnosis of mesenteric vein thrombosis by ultrasound and magnetic resonance imaging, and the effectiveness of early thrombolytic therapy without the need for surgical intervention.

Sixteen patients with mesenteric venous thrombosis were reviewed retrospectively during a period from 1983 to 1987. Twelve patients had progressive abdominal pain, three had gastrointestinal bleeding, and one had general malaise. Seven of these 16 patients had previous deep-vein thrombosis. After negative routine gastrointestinal and hepatobiliary evaluation, 11 patients underwent an infusion computerized tomographic scan. Of these, 10 had superior mesenteric vein thrombosis; three of these 10 patients had portal vein thrombosis. Selective arteriography was done in two patients because of gastrointestinal bleeding, and a diagnosis of mesenteric vein thrombosis was made on the venous phase of the examination. The remaining four patients developed acute abdominal symptoms requiring surgical exploration, at which time mesenteric venous thrombosis was discovered. An identifiable coagulopathy was detected in nine patients (protein C deficiency in six, protein S deficiency in two, and factor IX deficiency treated with factor IX concentrate in one). No case of congenital antithrombin-III deficiency was identified. Six of these nine patients had a past history of deep venous thrombosis. Of five patients who underwent surgical exploration, all required bowel resection. In follow-up, two patients died of intestinal necrosis and a third died of associated pancreatic cancer. Thirteen patients were discharged from the hospital. Treatment of coagulopathy was by heparin in three patients and sodium warfarin (Coumadin) in four patients. Long-term anticoagulation was not instituted because of gastrointestinal bleeding in three and cirrhosis in three patients. Mesenteric venous thrombosis can occur without gangrenous bowel. Diagnosis should be suspected when acute abdominal symptoms develop in patients with prior thrombotic episodes and a coagulopathy.(ABSTRACT TRUNCATED AT 250 WORDS)

Six cases of mesenteric venous thrombosis have occurred in the metropolitan area from 1982 through 1985. The most common findings were nonspecific abdominal pain associated with nausea and vomiting, subjective distress disproportionate to the objective findings, and signs of decreased intravascular fluid volume. In all six cases there was a rapid progression of physical findings to a level commensurate with the initial complaint. The most consistent laboratory abnormalities were an increase in leukocyte precursors, an elevated lactate dehydrogenase, and a mild metabolic acidosis. Mesenteric venous thrombosis is an unusual disease that is difficult to diagnose and manage.

Mesenteric vein thrombosis is a rare disorder which can develop rapidly with intestinal infarction or subacutely with abdominal pain due to intestinal ischemia. Despite the availability of modern diagnostic tools, which allow an early diagnosis in most cases, the mortality from this disease has not significantly diminished over the years. The problem is that the syndrome is rare and unusual and the clinical presentation is usually vague or confusing. Particularly in cirrhotic patients, this diagnosis requires the exclusion of several other complications of liver disease, like spontaneous bacterial peritonitis, tense ascites or portal thrombosis. Here, we report the occurrence of acute mesenteric vein thrombosis in two patients with liver cirrhosis. Severe subcontinuous abdominal pain out of proportion to the physical findings and abdominal distension were the major symptoms in both patients. Magnetic resonance imaging in one case and ultrasound scan with color Doppler followed by computed tomography in the other patient confirmed the diagnosis and enabled an appropriate early therapy to be undertaken.

Mesenteric venous thrombosis is a rare disease with no specific signs. It's major risk is intestinal ischaemia and necrosis. We report the case of a young women who presented with unexplained abdominal pain and subnormal abdominal ultrasound. The diagnosis was made on laparoscopic exploration which allowed anticoagulant therapy followed by proximal and distal divertingostomies of the ischemic bowel. Small bowel continuity was re-established after 3 month of total parenteral nutrition. The patients is doing well 1 year after surgery. She is still under anticoagulant therapy. The etiology found was a hypermegacaryocytosis as seen in myeloproliferative disease.

Mesenteric vein thrombosis is generally difficult to diagnose and can be fatal. A case of extensive thrombosis of the mesenteric and portal veins was diagnosed early and successfully treated in a 26-year-old man with Down syndrome who was admitted to hospital because of abdominal pain, severe nausea and high fever. Ultrasonography revealed moderate ascites, and there was minimal flow in the portal vein (PV) on the Doppler examination. Computed tomography (CT) showed remarkable thickening of the walls of the small intestine and extensive thrombosis of the mesenteric, portal and splenic veins. Because neither intestinal infarction nor peritonitis was seen, combined thrombolysis and anticoagulation therapy without surgical treatment was chosen. Urokinase was administered intravenously and later through a catheter in the superior mesenteric artery. Heparin and antibiotics were given concomitantly. The patient's symptoms and clinical data improved gradually. After 10 days, CT revealed that collateral veins had developed and the thrombi in the distal portions of the mesenteric veins had dissolved, although the main trunk of the PV had not recanalized. The only risk factor of thrombosis that was detected was decreased protein S activity.

Mesenteric vein thrombosis is an uncommon type of intestinal ischemia that can be associated with significant mortality if its diagnosis is delayed. We experienced two patients with hematological disorders--non-Hodgkin's lymphoma (NHL) and pure red cell aplasia (PRCA)--who developed superior mesenteric vein (SMV) thrombosis during treatment. Neither of the patients had underlying disorders of the anticoagulant system that might have produced a hypercoagulable state. The first patient developed SMV thrombosis immediately after chemotherapy for NHL. This patient also had portal hypertension due to chronic hepatitis B. Direct injury to endothelial cells by the anti-cancer drugs and alteration of blood flow were the probable causes of the SMV thrombosis. The second patient with PRCA had regularly taken prednisolone, and this had induced a hypercoagulable state. The clinical symptoms of SMV thrombosis are usually non-specific, and in our patients vague, crampy abdominal pain without bloody diarrhea was the only complaint. Abdominal CT scan under a clinical suspicion of SMV thrombosis revealed the thrombi in the SMV. Urgent surgical resection of the infarcted bowel and immediate postoperative anticoagulation resulted in a favorable outcome. Clinicians should be aware of the vague symptoms of SMV thrombosis, as early diagnosis and urgent therapy are essential to prevent a fatal outcome.

In portal vein thrombosis, various hypercoagulable conditions and inherited or acquired thrombophilias have already been described as predisposing factors. In a 33-year-old man admitted to a hospital with upper abdominal pain, a partial portal vein and upper mesenteric vein thrombosis, respectively, and a complete splenic vein thrombosis were diagnosed. Further diagnostic procedures showed no evidence for local precipitating factors or any underlying infectious, paraneoplastic or inflammatory disease. Thrombophilia screening demonstrated elevated factor VIII levels (206 %) and von Willebrand factor levels (> 440 %). An acute-phase reaction was excluded. Oral anticoagulant therapy with phenprocoumon was started. Factor VIII and von Willebrand factor were reproducibly elevated to high activity levels over a period of 12 months in absence of acute or chronic inflammatory reaction. Increased levels of factor VIII and von Willebrand factor may play a pathogenetic role in the development of portal, splenic, and mesenteric thrombosis.
