ObjectiveThis study aims to determine the incidence, timing, and risk factors of clinical venous thromboembolism. MethodsA cohort of patients who had major gynecologic cancer surgery between 1998 and 2008 was identified. Secondarily, a nested case-control design wherein patients who had clinical VTE within 90 days after surgery were considered cases. Controls were matched on age, race, surgery date, and cancer site. Risk factors were evaluated for VTE within 90 days, and late VTE between 8 and 90 days. ResultsWe identified 4158 women, 18 years or older, without a history of recent thrombosis. We observed 126 cases of clinical VTE within 90 days of surgery (incidence 4%) of which 96 (76%) occurred after post-operative day 7. In a multivariable model including age, ASA, BMI, race, and site of cancer, only ovarian cancer was a significant predictor for VTE within 90 days (HR 2.8; 95% CI 1.6, 5.0).In the nested case-control study, we identified hospital stay ≥ 5 days (OR 2.8; 95% CI 1.5, 5.1) and prior VTE (OR 2.6; 95% CI 1.1, 6.1) as significant risk factors for VTE within 90 days. Only hospital stay ≥ 5 days (OR 2.5; 95% CI 1.3, 4.7) was significantly associated with late VTE between 8 and 90 days. ConclusionIn gynecologic cancer patients, over 75% of VTE are detected more than 7 days after surgery. Patients with ovarian cancer, prolonged hospitalization, or a history of VTE are at highest risk of developing clinical VTE. Such patients would be optimal candidates for clinical trials evaluating extended VTE prophylaxis. 相似文献

Objective: Women during pregnancy or puerperium have a higher risk of venous thromboembolism (VTE). The reported incidence of pregnancy-associated VTE from literature varied considerably. To summarize the overall incidence of the disease, we conducted this meta-analysis. Methods: We searched PubMed, EMBase and CNKI (China National Knowledge Infrastructure) for studies that reported the incidence of VTE during pregnancy or puerperium. The quality of included studies was assessed using the Newcastle–Ottawa scale and the meta-analysis was conducted using R software and Meta analyst Beta 3.13. Sensitivity analyses were performed to analyze the robustness of the results and publication bias was assessed using Egger's test. Results: Twenty-seven articles met the inclusion criteria. The pooled incidence rate was 1.4‰ (1.0–1.8‰) for VTE, 1.1‰ (1.0–1.3‰) for deep vein thrombosis (DVT) and 0.3‰ (0.2–0.4‰) for pulmonary embolism (PE). The weighted proportion of VTE postpartum was 57.5% and the pooled proportion of right-sided DVT was 27.9%. We noted substantial heterogeneity among individual studies. Conclusions: Women during pregnancy or puerperium are associated with a higher morbidity of VTE. Physicians should be of high vigilance to pregnancy-associated VTE, especially for women postpartum. 相似文献

The main inherited thrombophilias (antithrombin deficiency, protein C and S deficiency, FVL, the prothrombin gene variant, and MTHFR C677T homozygotes) have a combined prevalence in Western European populations of 15% to 20%. One or more of these inherited thrombophilias is usually found in approximately 50% of women who have a personal history of VTE. Obstetricians must therefore be aware of the interaction between thrombophilias and the procoagulant state of pregnancy and should have an understanding of additional risk factors that may act synergistically with thrombophilias to induce VTE. Such knowledge combined with the appropriate use of thromboprophylaxis and treatment in women who have objectively confirmed VTE continue to improve maternal and perinatal outcomes. 相似文献

Pulmonary thromboembolism (PTE) is the major cause of maternal death in the UK, with recent trends showing an increase in the numbers of deaths. Underlying PTE is the problem of deep venous thrombosis (DVT). An appreciation of risk factors, particularly, thrombophilia, and signs or symptoms suggestive of thromboembolism, coupled with objective diagnosis and treatment should reduce mortality and morbidity. There are particular considerations with regard to the management of thrombosis in pregnancy, especially the use of anticoagulants. Low-molecular-weight heparins are now replacing unfractionated heparin for the treatment of DVT and PTE in pregnancy. 相似文献

During pregnancy, women have a 4- to 5-fold increased risk of thromboembolism. Candidates for anticoagulation in pregnancy include women with current thrombosis, a history of thrombosis, risk factors for postpartum thrombosis, and some women with thrombophilia and a history of poor pregnancy outcome. Although, there are no large trials of anticoagulants in pregnancy and recommendations for their use are based on case series and the opinion of experts, observational studies demonstrate the benefit of heparins in reducing the risk of recurrent thromboembolism in pregnancy. A practical approach to the prevention and treatment of thromboembolism in pregnancy is outlined. 相似文献

Pulmonary thromboembolism is the leading cause of maternal death in the UK. Optimal management of deep venous thrombosis and pulmonary thromboembolism requires an appreciation of risk factors, particularly thrombophilia, and signs or symptoms suggestive of venous thromboembolism, along with objective diagnosis and treatment with anticoagulants. Low molecular weight heparins are now replacing unfractionated heparin for the treatment of deep venous thrombosis and pulmonary thromboembolism in pregnancy because of the lower risk of side effects, ease of administration and reduced need for monitoring. 相似文献

ObjectiveKnowledge of the incidence of pregnancy-related thromboembolism and its risk factors is clinically important because thromboembolism is the leading cause of maternal death. However, there are insufficient large population-based studies on this topic. The purpose of this study was to estimate the incidence of and identify the risk factors for thromboembolism during pregnancy and puerperium. Materials and methodsWe analyzed data from 2007 to 2016 using the Health Insurance Review and Assessment Service (HIRA) database. Women who gave birth in the Republic of Korea were identified. Thromboembolism was defined as the simultaneous presence of both the diagnostic and test codes. Risk factors for thromboembolism were identified using logistic regression. ResultsA total of 1,188 delivery episodes with thromboembolism were extracted from 4,243,393 delivery episodes. The incidence of thromboembolism was 0.28 per 1,000 deliveries, and it increased over the 10-year period. The incidence of antepartum thromboembolism was 0.1 per 1,000 deliveries (418 cases), and the incidence of postpartum thromboembolism was 0.18 per 1,000 deliveries (770 cases). Thromboembolism was associated with ovarian hyperstimulation syndrome, low socioeconomic status, multiple birth, cesarean birth, preeclampsia, postpartum hemorrhage, placenta previa, advanced maternal age, hyperemesis and primiparity. The factors associated with mortality from thromboembolism were cesarean birth and preterm premature rupture of membranes. ConclusionThe incidence of pregnancy-related thromboembolism increased over the 10-year study period. Low socioeconomic status, ovarian hyperstimulation syndrome, cesarean delivery and premature rupture of membranes were high-risk factors. This study provides an important reference for thromboprophylaxis for pregnancy-related thromboembolism. 相似文献

Cerebral venous thrombosis (CVT) and Budd-Chiari syndrome (BCS) are rarely encountered thrombotic diseases of two different vascular systems. A 20-year-old woman in the 14th week of pregnancy was brought to the emergency department with complaints of sudden headache and loss of vision. Thrombosis in the left transverse and sigmoid sinus was demonstrated at MR angiography. She was diagnosed with BCS by using hepatic Doppler ultrasonography after an elevation of liver enzymes. Although CVT and BCS are rarely seen during pregnancy, they need emergency treatment because of high mortality. 相似文献

The objective of this study is to evaluate the association between venous thromboembolism (VTE) in pregnancy with thrombophilic factors. Thirty pregnant women with VTE were compared with 30 pregnant women matched by age and race without VTE and evaluated for risk factors and thrombophilia. Statistical analysis used two-tailed Fisher's exact test. VTE distribution was 30% in first trimester, 9% in 2nd trimester, 26% in 3rd trimester and 35% postpartum. Seventeen (57%) of VTE cases versus 2 (7%) of control cases had specific thrombophilia diagnosis ( p <0.001). The results were: Factor V Leiden mutation (27 vs. 3%) p = 0.026, MTHFR homozygous 677 mutation (10 vs. 44%) p = 0.017, prothrombin gene mutation (11 vs. 0%), protein C deficiency (7 vs. 0%), antiphospholipid antibodies (27 vs. 3%) p = 0.026, mean lipoprotein levels 49 versus 23 mg/dL, p = 0.008, mean homocysteine levels 7.8 versus 7.1 umol/L. An association is suggested between thromboembolic events in pregnancy and thrombophilia, especially Factor V Leiden gene mutation and elevated antiphospholipid antibodies. A new finding is the association of elevated lipoprotein A levels with thromboembolic events in pregnancy. 相似文献
