1/51. Portal, mesenteric, and splenic vein thromboses after splenectomy in a patient with chronic myeloid leukemia variant with thrombocythemic onset.

    Portal, mesenteric, or splenic vein thrombosis is a very uncommon complication with significant mortality in the patients undergoing splenectomy for hematologic disorders. We report a 49-year-old woman who developed portal, superior mesenteric, and splenic vein thromboses after splenectomy. Four years before the event, she presented with a marked thrombocytosis and was diagnosed to have chronic myeloid leukemia variant with thrombocythemic onset as evidence by philadelphia (Ph1) chromosome and a b3a2 BCR/ABL transcript. Six weeks after splenectomy, she developed severe epigastric pain. The diagnosis of thromboses of portal, mesenteric, and splenic veins was made by computed tomography scan and Doppler sonogram. She was successfully treated with antegrade intraarterial urokinase therapy via superior mesenteric artery and long-term anticoagulant therapies. To our knowledge, our patient is the first case of portal, mesenteric, and splenic vein thromboses after splenectomy in a patient with CML variant with thrombocythemic onset successfully treated with antegrade intraarterial thrombolytic therapy followed by anticoagulant therapies.

2/51. paraneoplastic syndromes of leukocytosis, thrombocytosis, and hypercalcemia associated with squamous cell carcinoma.

    paraneoplastic syndromes including leukocytosis, thrombocytosis and hypercalcemia are occasionally seen in patients suffering from progressive malignant disorders. Recent studies have revealed the production of several humoral factors by tumor cells and normal splenic cells of tumor-bearing patients to be the major cause of these reactions. granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte-colony stimulating factor (G-CSF), parathyroid hormone-related peptide, interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF) have been implicated. We describe a 58-year-old Japanese man with squamous cell carcinoma (SCC) on the left sole, which developed in a deep linear scar after a train crash. He developed pulmonary and lymph node metastases, then leukocytosis (57,110/mm3 with 95% neutrophilia), thrombocytosis (86.3 x 10(4)/mm3), and hypercalcemia (7.0 mEq/1), and finally cachexia, followed by death. serum G-CSF, IL-1 alpha, IL-1 beta, and TNF-beta were determined; revealing G-CSF and IL-1 beta levels were above the upper limits of their normal ranges at 39.2 pg/ml and 4.63 pg/ml, respectively. It is probable that these humoral factors were partially responsible for the paraneoplastic syndromes induced by the cutaneous SCC with metastasis in the present case.

3/51. Clinical implications of elevated PAI-1 revisited: multiple arterial thrombosis in a patient with essential thrombocythemia and elevated plasminogen activator inhibitor-1 (PAI-1) levels: a case report and review of the literature.

    Plasminogen activator inhibitor (PAI-1), a member of the serine protein family, is the most active in vivo inhibitor of fibrinolysis induced by plasminogen, tissue plasminogen activator (tPA), and urokinase type plasminogen activator (uPA). While the association between elevated PAI-1 and thrombogenesis has been well studied for several disease processes, including coronary disease, postoperative deep vein thrombosis (DVT), myocardial infarction, malignancy, and diabetes, few studies have concentrated on the correlation between elevated PAI-1 levels and thrombogenesis in patients with myeloproliferative disorders. Essential thrombocythemia (ET), a chronic myeloproliferative disorder, characterized by the overproduction of poorly functioning platelets, is associated with both thrombotic and hemorrhagic life-threatening complications. Although the events resulting in thrombogenesis in such patients may be multifactorial in nature, an association between elevated PAI-1 levels and thrombus formation has been proposed. Herein we present a patient diagnosed with ET complicated by multiple episodes of arterial thrombosis. Elevations in PAI-1 levels were documented repeatedly. The role of elevated PAI-1 when associated with other disease processes is also discussed.

4/51. Internal carotid artery occlusion in a patient with malignant peritoneal mesothelioma: is it a sign of malignancy-related thrombosis?

    To our knowledge, the occlusion of arteries and platelet hyperaggregation have not been reported in patients with malignant mesothelioma. However, venous thromboembolism, especially in the pulmonary vasculature in association with thrombocytosis and hyperfibrinogenemia, are commonly noticed in this disorder. Furthermore, we detected enhanced platelet aggregation in a case of malignant peritoneal mesothelioma with internal carotid artery occlusion in whom there were postsplenectomy thrombocytosis and hyperfibrinogenemia. The possible mechanisms of ICA occlusion in this patient, including the role of MPM and postsplenectomy state, thrombocytosis, platelet functional changes, and other factors were investigated and discussed.

5/51. Medical management of a large aortic thrombus in a young woman with essential thrombocythemia.

    Aortic thrombus formation is rare in the patients with essential thrombocytosis (ET); therefore, no guidelines for its management have been established. Embolism from ET-associated large vessel thrombi is potentially lethal and has been managed surgically in a few reported cases. We describe herein a 45-year-old black woman with ET found to have a 3.5-cm, pedunculated intra-aortic thrombus at the thoracoabdominal junction. How to treat this potentially devastating aortic thrombus was a management dilemma. We believed, based on the patient's diagnosis of ET and the histology of similar thrombi in 1 reported series, that the aortic thrombus was a "white thrombus" consisting primarily of aggregated platelets with a minimal fibrin network and almost no entrapped erythrocytes. The patient was treated with aspirin, 325 mg daily, as a platelet antiaggregating agent and hydroxyurea, 1,500 mg daily, to reduce the platelet count to less than 450 x 10(9)/L. The thrombus resolved without severe thromboembolic events. To our knowledge, this is the first reported case of a large intra-aortic thrombosis associated with ET that has been successfully managed with medical therapy alone.

6/51. Portal or hepatic vein thrombosis as the first presentation of a myeloproliferative disorder in patients with normal peripheral blood counts.

    myeloproliferative disorders (MPD) are associated with an increased risk of thrombotic complications. We describe three patients with portal or hepatic vein thrombosis and normal peripheral blood counts who had MPD on bone marrow morphology and growth factor-independent megakaryocyte or erythroid colony growth in vitro. The peripheral blood counts have become abnormal subsequently in two patients. patients presenting with unexplained portal or hepatic vein thrombosis should be investigated systematically for the presence of a MPD, which may not be apparent using conventional diagnostic criteria.

7/51. Acute myelogenous leukemia associated with extreme symptomatic thrombocytosis and chromosome 3q translocation: case report and review of literature.

    Acute leukemias with thrombocytosis have been recently linked with structural abnormalities of the short arm of chromosome 3. A 46-year-old man with a 2-month history of recurrent transient ischemic attacks and abdominal pain developed an ischemic left foot and a gangrenous toe as his initial symptoms. platelet count was 3.5 x 10(6)/microL, and despite plateletpheresis, the patient required left-leg amputation. Pathologic examination was remarkable for arterial thrombosis in the absence of atherosclerotic lesions. A diagnosis of acute myeloid leukemia with a novel translocation between chromosomes 3q21, 16, and 7 was made. Induction therapy was unsuccessful, and the patient died of overwhelming sepsis within 5 weeks of diagnosis. The striking features of this case were extreme symptomatic thrombocytosis, peripheral gangrene without atherosclerosis, and a novel three-way chromosomal translocation involving chromosome 3q21.

8/51. thrombocytosis and recurrent hepatic outflow obstruction (budd-chiari syndrome) after successful thrombolysis: case report and literature review.

    Approximately two thirds of cases of hepatic flow obstruction are due to myeloproliferative disorders. Restoration of hepatic blood flow is the essential goal of treatment. thrombolytic therapy seems to achieve good results at least in selected cases. A 32-year-old woman is presented, with an intermittent increase in platelet count (526-725 x 10(9)/L), two previous spontaneous abortions and acute symptomatic occlusion of hepatic veins, and in whom a diagnosis of essential thrombocythemia was initially carried out in agreement with the polycythemia vera study group criteria. She received recombinant tissue plasminogen activator followed by heparin with restoration of normal hepatic outflow. Asymptomatic re-occlusion of the hepatic veins was observed 1 year later, despite adequate continuous warfarin treatment. angiography showed marked narrowing of the intrahepatic cava vein due to extrinsic compression by an enlarged liver, not due to a new thrombosis so that no specific intervention could be performed. In the presence of a dearly documented hepatic vein thrombosis, thrombolytic therapy should be considered. The patient was given low-molecular-weight heparin with a dramatic reduction in previously elevated fibrinogen level and a good control of the hepatic function.

9/51. Paradoxical arterial emboli causing acute limb ischemia in a patient with essential thrombocytosis.

    Acute arterial occlusion can be the result of acute thrombosis or systemic embolism. Paradoxical embolism of a venous thrombosis through a right-to-left shunt is an important cause of acute limb ischemia. We describe a young patient with acute limb ischemia who was found to have multiple deep venous thromboses causing arterial embolization through a patent foramen ovale. Essential thrombocytosis was found to be the risk factor for venous thromboses in this patient. The patient was managed with embolectomy and anticoagulation along with chemotherapeutic cytoreduction of platelet count. This case illustrates the importance of considering the systemic embolism as a cause of acute arterial occlusion. The presence of a hypercoagulable status such as chronic myeloproliferative disorder does not eliminate the possibility of systemic embolism in the event of acute arterial occlusion. patients presenting with acute limb ischemia should be evaluated for embolic sources. The presence of deep venous thrombosis in such a patient should prompt the evaluation for a patent foramen ovale.

10/51. Thrombocythemia and hemoperitoneum after transvaginal oocyte retrieval for in vitro fertilization.

    OBJECTIVE: To present the first report of massive hemoperitoneum in a case of essential thrombocythemia after transvaginal oocyte retrieval for IVF and review the relevant literature related to the management of patients with this condition. DESIGN: Case report. SETTING: Assisted conception unit of a tertiary care university hospital in the United Kingdom. PATIENT(S): A 37-year-old woman with essential thrombocythemia who developed massive intra-abdominal bleeding after transvaginal oocyte retrieval for IVF. INTERVENTION(S): Emergency laparotomy and right salpingoophorectomy. RESULT(S): resuscitation of the patient. MAIN OUTCOME MEASURE(S): overall management of the patient is discussed. CONCLUSION(S): The management of patients with essential thrombocythemia at the childbearing period poses a difficult problem. fertility may be reduced, and an adverse outcome of pregnancy due to thrombotic or bleeding complications is a matter of concern. A multidisciplinary approach with close and early cooperation with the hematologists before initiation of IVF therapy for patients with essential thrombocythemia is essential. Efforts should be made to reduce the platelet count and assess the platelet function before embarking on IVF, keeping in mind the double jeopardy from bleeding and thrombosis in these cases.
