1/80. pulmonary embolism during labor and the effect on the fetus monitored with oxycardiotocography.We report on a rare case of pulmonary embolism which we observed in the second stage of labor. For fetal surveillance we used oxycardiotocography (OCTG), an experimental system which combines internal CTG and pulse oximetry which enabled us to observe hemodynamic reactions of the unborn child and the effect on maternal-fetal gas exchange. It was possible to record marked fetal bradycardia simultaneously with decrease in oxygen saturation in the fetal arterial system during the acute event.- - - - - - - - - - ranking = 1keywords = pulmonary embolism, embolism (Clic here for more details about this article) |
2/80. Catheter-directed thrombolysis for thromboembolic disease during pregnancy: a viable option.Anticoagulation with intravenous heparin has been the standard treatment for the management of gestational thromboembolic complications. Catheter-directed thrombolysis is an encouraging approach for the treatment of thromboembolic disease and has not been previously reported during pregnancy. One gravid woman with pulmonary embolism, critically ill, and hemodynamically compromised, and two gravid women with iliofemoral venous thrombosis, who failed to respond to standard treatment with intravenous heparin, were treated with catheter-directed urokinase. All three patients experienced rapid resolution of symptoms and successful pregnancy outcomes. In our three patients, catheter-directed thrombolysis for thromboembolic disease during pregnancy allowed rapid resolution of hemodynamic abnormalities and/or resolution of thrombus. Catheter-directed thrombolysis offered a reasonably safe alternative to prolonged medical management in these young, otherwise healthy, patients. Long-term, it may prevent the postphlebitic syndrome.- - - - - - - - - - ranking = 0.81235775999723keywords = pulmonary embolism, embolism (Clic here for more details about this article) |
3/80. thrombophlebitis and pulmonary embolism with surgical intervention in the third trimester.A case of acute deep vein thrombophlebitis and pulmonary embolism in late gestation has been presented with a discussion of diagnostic modalities, therapeutic regimens, and theoretical considerations. It is our belief that aggressive medical management is best accomplished by giving heparin intravenously as the primary anticoagulant. When medical management is best accomplished by giving heparin intravenously as the primary anticoagulant. When medical management is not effective or if embolism occurs, surgical intervention, consisting of vena caval clipping and ovarian vein ligation with scrupulous attention to detail, is indicated. Further, support to prophylaxis of abruptio placenta secondary to the mechanism espoused by Mengert et al is added by the course of this patient.- - - - - - - - - - ranking = 4.1086993599868keywords = pulmonary embolism, embolism (Clic here for more details about this article) |
4/80. ED echocardiography for peripartum cardiomyopathy.Although peripartum cardiomyopathy is uncommon, emergency physicians should be knowledgeable of it because of its high morbidity and mortality. Emergency physicians should be alert to the fact that the clinical presentation of peripartum cardiomyopathy is nonspecific. Its clinical manifestations are found in other medical conditions that can present in the late prepartum or postpartum patient. We present a case of peripartum cardiomyopathy that illustrates how its nonspecific respiratory signs and symptoms led to an initial diagnosis of pulmonary embolism. The case also highlights the need for echocardiography in the evaluation of peripartum cardiomyopathy. We discuss the clinical presentation, diagnosis, and treatment of peripartum cardiomyopathy.- - - - - - - - - - ranking = 0.81235775999723keywords = pulmonary embolism, embolism (Clic here for more details about this article) |
5/80. Management of heparin-associated thrombocytopenia in pregnancy with subcutaneous r-hirudin.heparin-induced thrombocytopenia type II is a serious, immune-mediated complication of heparin therapy. Due to its low cross-reactivity with heparin-associated antibodies (10-20%), danaparoid has successfully been administered in these patients. In recent studies, r-hirudin as a potent and specific thrombin inhibitor, was demonstrated to be a safe and effective anticoagulant. We report a pregnant woman with systemic lupus erythematosus and recurrent venous thromboembolism who suffered from heparin-induced thrombocytopenia type II while treated with dalteparin sodium. Positive cross-reactivities with danaparoid were found. Anticoagulation with 15 mg subcutaneous r-hirudin was performed twice daily from the 25th week of pregnancy until delivery. No thromboembolism or bleeding or fetal toxicity of r-hirudin was detected. Recombinant hirudin is a potent and specific thrombin inhibitor that can be used as a safe and effective anticoagulant in pregnancy.- - - - - - - - - - ranking = 3.5459316154218keywords = thromboembolism, embolism (Clic here for more details about this article) |
6/80. Internal jugular vein thrombosis in association with the ovarian hyperstimulation syndrome.Thrombosis of the internal jugular vein is a rare entity with the potential for serious consequences. Most of the reported cases of jugular venous thrombosis have occurred in the presence of an indwelling venous catheter, an established hypercoagulable state, or in association with head and neck sepsis. This report presents a case of a patient in whom jugular venous thrombosis developed during the first trimester of pregnancy after in vitro fertilization. Thromboembolism in these circumstances can be related to a condition known as the ovarian hyperstimulation syndrome. The presentation of severe neck pain in pregnant women, especially in those who have undergone assisted reproduction procedures, should prompt evaluation by duplex scan to evaluate the jugular veins for thrombosis. Anticoagulation is the treatment of choice.- - - - - - - - - - ranking = 0.046910560000693keywords = embolism (Clic here for more details about this article) |
7/80. Coexisting dysfibrinogenemia (gammaR275C) and factor v Leiden deficiency associated with thromboembolic disease (fibrinogen Cedar Rapids).fibrinogen Cedar Rapids is a heterozygous dysfibrinogenemia (gammaR275C) that was associated with thromboembolism during and following pregnancy in three second-generation family members who also were heterozygotic for factor v Leiden (V R506Q). Like other dysfibrinogenemias with substitutions at position 275 of the gamma-chain, fibrinogen Cedar Rapids is characterized by defective end-to-end intermolecular fibrinogen and fibrin 'D : D' associations, a fibrin network structure that is composed of thicker and more highly branched fibers, normal fibrin 'D: E' associations, and normal factor xiii-mediated crosslinking of fibrinogen and fibrin. In addition, Cedar Rapids fibrinogen and fibrin displayed delayed plasmin lysis rates. Compared with normal fibrinogen, platelet aggregation or platelet fibrinogen receptor clustering was defective in the presence of fibrinogen Cedar Rapids. Most subjects with gammaR275 mutations do not experience clinical thrombotic disorders, suggesting that the combination of a factor v Leiden defect and a gammaR275C dysfibrinogenemia predisposes to thromboembolic disease.- - - - - - - - - - ranking = 1.7729658077109keywords = thromboembolism, embolism (Clic here for more details about this article) |
8/80. Accumulation of low molecular mass heparin during prophylactic treatment in pregnancy.A history of thromboembolism is associated with an increased risk of new thromboembolic events during pregnancy. Prophylaxis with heparin during pregnancy implicates long-term treatment with daily injections with either unfractionated heparin (UFH) or low molecular mass heparin (LMMH). Prolonged treatment with heparin may result in endothelial absorption and drug accumulation. In order to test this hypothesis, anti-FXa activity during pregnancy was measured in four women allergic to conventional UFH, who were treated with LMMH (dalteparin; Pharmacia). It was found that, at the commencement of treatment, it took more than 8 days to reach a steady maximum peak value, located 3 h after the given dose. One daily dosage of 5,000 IU anti-Xa resulted in a measurable level of FXa for 24 h in pregnancy week 40, compared with 17h at pregnancy week 37. The implications of an elevated anti-FXa activity during pregnancy, especially during the third trimester and at partus, are discussed. We present a reduced dose regime near term and during delivery.- - - - - - - - - - ranking = 1.7729658077109keywords = thromboembolism, embolism (Clic here for more details about this article) |
9/80. Clinical study of venous thromboembolism during pregnancy and puerperium.We encountered 16 cases of venous thromboembolism (VTE) in women during pregnancy and/or puerperium over the past 15 years at our perinatal center, representing 0.14% of all patients who delivered babies. The present study was undertaken to analyze the risk factors, clinical course and outcomes in these 16 cases. The ages of the patients varied from 29 to 39 years. Four women had pulmonary embolism (PE), 3 of which after caesarean section (C/S) at 35 to 40 weeks, and one case after ovarian cystectomy at 13 weeks of gestation. Twelve cases had deep venous thrombosis (DVT), 4 of which during pregnancy, and the remaining 8 cases after C/S. Four patients who had DVT during a normal course of pregnancy had severe thrombophilia: antiphospholipid antibody syndrome, a history of thrombosis and antithrombin (AT) deficiency. They were treated with heparin with or without AT and had healthy babies via successful vaginal deliveries. The common risk factors in 3 cases of PE with C/S was prolonged bed rest due to threatened premature delivery with total placenta previa, uterine myoma and ehlers-danlos syndrome. Other risk factors were massive bleeding, and positive lupus anticoagulant. However, the case of the ovarian cystectomy had only one risk factor, which was obesity. This patient died but the remaining patients recovered with treatment. Because of the low incidence of thrombosis in the Japanese population, prophylactic anticoagulant therapy has not routinely been given to patients undergoing obstetrical operations. However, proper management including prophylactic anticoagulant therapy might be considered for risk patients, depending on the risk factors.- - - - - - - - - - ranking = 9.6771867985517keywords = thromboembolism, pulmonary embolism, embolism (Clic here for more details about this article) |
10/80. pulmonary edema and wheezing after pulmonary embolism.A young, pregnant woman with angiographically proved pulmonary emboli developed pulmonary edema and wheezing without evidence of left ventricular failure. This cast study points out the unusual association of pulmonary embolism with pulmonary edema, wheezing, and hyper-reactive airways in a patient with a positive family history of allergy, but no antecedent history of bronchospasm. Mechanisms for the occurrence of noncardiogenic pulmonary edema and wheezing after pulmonary embolism are reviewed.- - - - - - - - - - ranking = 4.8741465599834keywords = pulmonary embolism, embolism (Clic here for more details about this article) |
