Essential thrombocythemia (ET) is a rare disorder in children. An 11-year-old white boy was first seen in January 1986 with symptoms of abdominal pain. His platelet count was 1.5 million/mm3. Other hematological values and coagulation studies, including bleeding time, were normal. There was laboratory evidence of mild platelet dysfunction. Using the criteria of the Polycythemia Vera Study Group, a diagnosis of ET was made. He developed frequent headaches. Aspirin was prescribed for the next 2 years at varying doses and frequency. During the period, platelet counts ranged between 1 and 3 million/mm3. In view of progressive headaches and evidence of increasing platelet dysfunction, further treatment was indicated. The use of a new agent, anagrelide, reported effective in adults with ET, resulted in amelioration of symptoms and improvement in quantitative and qualitative platelet control with no significant untoward effects.

Budd-Chiari syndrome is caused by the obstruction of the hepatic veins or of the inferior vena cava. It is characterized by the classic symptomatological triad: ascites, hepatomegaly, and abdominal pain. In 2/3 cases its etiology remains unknown. Budd-Chiari syndrome may be associated with polycythemia vera, neoplasms, chronic leukemia, congenital abnormalities, hypercoagulation conditions, pregnancy, oral contraceptives, and constrictive pericarditis. Even though its clinical diagnosis is difficult, radiology plays a decisive role with US, CT, MR imaging and, above all, angiography; the latter, together with liver biopsy, generally provides with an unquestionable diagnosis. Through the definition of stage of the disease, of level (intrahepatic, venous, caval, cardiac), of type (intrinsic or extrinsic), and degree of both obstruction and consequent development of collateral channels, radiology determines which patients should undergo a medical or a surgical treatment. In some case, percutaneous angioplasty can be performed. Four cases of Budd-Chiari syndrome, including two children, were investigated with US, CT, angiography, and liver biopsy; MR imaging was also employed in one case. The underlying cause was identified in 3 patients: constrictive pericarditis of probable congenital origin and web occlusion of the inferior vena cava near the right atrium in the 2 children; hepatic vein thrombosis due to essential thrombocythemia in the third case. In the fourth patient, thrombosis of the inferior vena cava and hepatic veins was unexplained. The diagnosis was established by means of liver biopsy and phlebography of the hepatic veins. Good diagnostic information was also supplied by non-invasive techniques, such as US, CT, and MR imaging.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical, analytical, evolutive and therapeutic aspects of 33 cases of polycythemia vera which were diagnosed according to the Polycythemia Vera Study Group criteria, are described. Mean age was 65 years with a slight predominance of females (54.5%). Hemorrhagic manifestations were the most frequent (67%) with a great number of patients with digestive manifestations consisting of GI hemorrhage, abdominal pain, portal or suprahepatic veins thrombosis. Splenomegaly was the most frequently found sign upon examination (73%). The mean hemoglobin leukocyte, and platelet levels were 18 g/dl, 16,000 mm3 and 738,000 mm3 respectively. It is note worthy the value of the erythropoietin for the differential diagnosis of secondary erythrocytosis as well as the value of the bone marrow histologic study which should be included in the diagnostic criteria of the disease. The evolution of the process is favorably altered by bleedings and chemotherapeutic cytoreduction which are often performed simultaneously.

Ischaemic colitis was not diagnosed until laparotomy in five cases. In two it was secondary to hypotension and multiple organ failure, in two it was atherosclerotic, and one had polycythemia vera. The diagnosis should always be considered in patients with abdominal distension--with or without diarrhoea and abdominal pain--so that treatment may be instituted before the onset of peritonitis.

The Budd-Chiari syndrome is a rare condition (0.4-.06 per cent in autopsy material) characterized by ascites, liver function disturbance and abdominal pain caused by thrombosis of the major hepatic veins. $ studies (N = 114) yield the following list of causes with percentages; Oral contraceptives, 18%; polycythemia vera, 13%; other myelo-proliferative disease, 4%; paroxysmal nocturnal hemoglobinuria, 5%; blood vessel malformation, 10%; malignancy, 6%; other simultaneous thrombosis, 3%, vasculitis, 2%; other (trauma, abscess, chronic active hepatitis, pregnancy) 5%; no known cause, 34%. The histories of 2 patients illustrate the difficulty of diagnosis, which is usually verified only by biopsy. One of the patients was a 20-year old woman who had used oral contraceptives for 5 years and presented changes consistent with myeloproliferative syndrome in the peripheral circulation and in the bone marrow, as well as a high cardiolipin antibody titer. Oral contraceptives have been cited as a cause of Budd- Chiari syndrome, but the proportion of oral contraceptives users among patients is no greater than among women in general. One recent French study (N = 33) gives a relative risk factor of 2.4 for women between 15 and 45 years old who have used oral contraceptives during the 12 months before onset of the disease. This risk factor parallels that for stroke, myocardial infarction, and venous thromboembolism. No cases of Budd- Chiari syndrome had been reported to the Swedish side-effects register through December 1988.

Of 501 patients with chronic myeloproliferative diseases (c-MPD) 18 developed thrombosis of major abdominal vessels including 6 with hepatic vein thrombosis (Budd-Chiari syndrome). The complication was seen in 14 of 140 (10%) patients with polycythemia vera (PV), 3 of 23 (13%) patients with essential thrombocythemia (ET), 1 of 106 (1%) patients with idiopathic myelofibrosis (IMF), and none of 232 patients with chronic myelogenous leukemia (CML). Leading symptoms and signs were abdominal pain, progressive splenomegaly, widening abdominal girth, ascites, venous collaterals, and nausea and vomiting. The diagnostic modalities with highest specificity were angiography and explorative laparotomy. A causal relationship between the thrombotic event and hematocrit, thrombocyte count, or hemostatic abnormalities at the time of diagnosis could not be established. Detailed laboratory tests of platelet function and coagulation and fibrinolytic parameters of 5 surviving patients did not show any specific defect. Despite medical and surgical intervention, 39% of the patients died within 2 months after diagnosis of the thrombosis. The majority of the survivors developed further complications like liver cirrhosis with portal hypertension and esophageal varices or the short bowel syndrome after extensive bowel resection for mesenterial infarction.

This is a report of a long term prospective study of 13 seriously ill patients with Budd-Chiari syndrome as a result of occlusion of the hepatic veins who were treated by side to side portacaval shunt from four to 78 weeks after the onset of symptoms and who were under observation for three to 16 years. The patient population was young, ranging in age from 19 to 45 years; seven were men and six were women. The presumed cause was the use of oral contraceptives in three, polycythemia rubra vera in two, Behcet disease in one patient and unknown in seven patients. All of the 13 patients had abdominal pain, marked ascites, hepatosplenomegaly, wasting and disturbed liver function. Diagnosis was based on the symptoms and signs: angiographic demonstration of hepatic vein occlusion and a patent inferior vena cava; pressure measurements that showed an inferior vena caval pressure that was normal or within the usual range for patients with massive ascites and an elevated wedged hepatic vein pressure that was much higher than the inferior vena caval pressure, and the results of biopsy of the liver showing centrilobular congestion and necrosis. Side to side portacaval shunt was very effective in decompressing the liver, reducing the mean corrected portal pressure from 240 millimeters of saline solution before to 7 millimeters of saline solution after the shunt. Operative survival rate was 92 per cent, and the long term survival rate for three to 16 years is 85 per cent. All of the survivors are free of ascites without requiring diuretic therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Although cases of hepatic vein thrombosis (Budd Chiari Syndrome) in oral contraceptive (OC) users have been reported in the literature, the association has not been definitively established. Hepatic vein thrombosis, an uncommon disorder, presents with right upper quadrant abdominal pain, hepatomegaly, and ascites. Diagnostic procedures include hepatic scintiscans, ultrasonography, computerized tomography and magnetic resonance imaging, determination of intrahepatic pressure, liver biopsy, and inferior vena cava and hepatic venography. Hepatic vein thrombosis may develop without an apparent underlying cause or as a complication of an illness known to be associated with vascular thromboses such as polycythemia rubra vera or paroxysmal nocturnal hemoglobinuria. In relation to the large numbers of women taking OCs, there have been very few cases of hepatic vein thrombosis. Evidence linking OC use to the development of hepatic adenomas is far more convincing. In a multicenter case-control study of 33 cases of hepatic vein thrombosis in women 15-45 years of age, each of whom was matched to 3-4 controls, the relative risk of hepatic vein thrombosis in OC users compared with nonusers was 2.37 (p 0.02). It was noted that the 1 patient with paroxysmal nocturnal hemoglobinuria, 5 of 12 patients with overt primary myeloproliferative disorder, and 7 of 8 patients with a forme fruste of a myeloproliferative disorder were OC users, suggesting that OCs--through their thrombogenic action--augmented the thrombotic tendency of the underlying condition. The objectives of therapy in hepatic vein thrombosis are to relieve the hepatic congestion and prevent further clot formation. The majority of patients die within 3 years of diagnosis.

Budd Chiari Syndrome, characterized by massive ascites, hepatomegaly, abdominal pain, and tenderness, nausea, and vomiting, is caused by obstruction of the hepatic venous outflow. Of the known causes of polycythemia rubra vera, hypernephroma, and other tumors invading the inferior vena cava have been most often reported, while pregnancy and oral contraceptives (OCs) have also been held as causes. In this paper the case is presented of a young woman, previously on OCs for 4 months, who developed the syndrome 2 weeks after delivery; she was also found to have multiple hepatic adenomas on laparotomy. The longterm use of OCs has been estimated to be associated with an annual incidence of liver cell adenoma of 3-4/100,000. Evidence suggests that the estrogen components, rather than the progesterone, of OCs seem more likely to cause liver cell adenoma since estrogens are carcinogenic in other organs and promote liver cell regeneration in rats. By interference with the metabolism of oncogenic bile salt derivatives, estrogen may exert its oncogenic effect. The patient is this case was told never to use OCs again since there is also evidence that the tumor may regress on stopping OCs, and she was advised against further pregnancies.

Hepatic vein thrombosis (Budd-Chiari Syndrome) is a rare disorder resulting from obstruction to the outflow of blood from the liver. The characteristic pathologic findings are intense congestion most pronounced around the terminal hepatic venules, cell necrosis, and a scant inflammatory reaction. Major clinical manifestations include hepatomegaly, right upper quadrant abdominal pain, and ascites. Disorders associated with hepatic vein thrombosis include those associated with a thrombotic tendency, such as polycythemia vera and paroxysmal nocturnal hemoglobinuria. Use of oral contraceptive agents probably increases tendency to develop hepatic vein thrombosis. Biochemical tests of the liver are of little value. The hepatic scan may be useful in suggesting the diagnosis with a marked decrease in uptake of isotope over affected areas of the liver. The diagnosis is confirmed by inferior vena caval and attempted hepatic venous catheterization. An associated thrombosis of the inferior vena cava is frequently found. Therapy in hepatic vein thrombosis is directed towards correction, in so far as possible, the underlying disorder, prevention of further extention of thrombosis, and management of ascites. Side-to-side portacaval or mesocaval shunt operation may convert the portal vein into an effective hepatic outflow vessel and reduce intrahepatic pressure and decrease injury. Mesoatrial shunts have proven useful in a few patients with hepatic vein thrombosis and either an inferior vena caval thrombosis or a marked pressure gradient from the abdomen to the thorax from ascites and an hypertrophied caudate lobe of the liver. For patients with extensive hepatocellular disease and portal hypertension, hepatic transplantation would seem to offer the best chance for survival.
