Objective To identify single-nucleotide polymorphisms (SNPs) associated with DVT. Design, Setting, and Patients We used 3 case-control studies of first DVT. A total of 19 682 gene-centric SNPs were genotyped in 443 cases and 453 controls from the Leiden Thrombophilia Study (LETS, 1988-1992). Twelve hundred six SNPs associated with DVT were reinvestigated in the Multiple Environmental and Genetic Assessment of Risk Factors for Venous Thrombosis study (MEGA-1, 1999-2004) in a subset of 1398 cases and 1757 controls. Nine SNPs associated with DVT in both LETS and MEGA-1 were investigated a third time in 1314 cases and 2877 controls from MEGA-2, a second subset of MEGA. Additional SNPs close to one SNP in CYP4V2 were genotyped in LETS and MEGA-1. Main Outcome Measure Odds ratios (ORs) for DVT were estimated by logistic regression. False discovery rates served to investigate the effect of multiple hypothesis testing. Results Of 9 SNPs genotyped in MEGA-2, 3 were strongly associated with DVT (P < .05; false discovery rate .10): rs13146272 in CYP4V2 (risk allele frequency, 0.64), rs2227589 in SERPINC1 (risk allele frequency, 0.10), and rs1613662 in GP6 (risk allele frequency, 0.84). The OR for DVT per risk allele was 1.24 (95% confidence interval [95%CI], 1.11-1.37) for rs13146272, 1.29 (95% CI, 1.10-1.49) for rs2227589, and 1.15 (95% CI, 1.01-1.30) for rs1613662. In the region of CYP4V2, we identified 4 additional SNPs (in CYP4V2, KLKB1, and F11) that were also associated with both DVT (highest OR per risk allele, 1.39; 95% CI, 1.11-1.74) and coagulation factor XI level (highest increase per risk allele, 8%; 95% CI, 5%-11%). Conclusions We identified SNPs in several genes that were associated with DVT. We also found SNPs in the region around the SNP in CYP4V2 (rs13146272) that were associated with both DVT and factor XI levels. These results show that common genetic variation plays an important role in determining thrombotic risk. 相似文献

The efficacy of low-molecular-weight heparin as a prophylactic agent was assessed in 150 consecutive patients over the age of 40 undergoing major abdominal surgery. Fifty of these patients received 1250 activated partial thromboplastin time (APTT) units of low-molecular-weight heparin every 12 hours: three developed isotopic deep vein thrombosis, which was confirmed by phlebography in two cases. The other 100 patients received a single injection of 1850 APTT units of low-molecular-weight heparin. Three of them developed isotopic deep vein thrombosis; phlebography failed to confirm the presence of thrombi in each case. None of the 150 patients studied died from fatal or contributory pulmonary emboli. Low-molecular-weight heparin was not associated with any increase in preoperative or postoperative bleeding. The effect of equal amounts of postoperative bleeding. The effect of equal amounts of low-molecular-weight heparin and unfractionated heparin on the coagulation mechanism during surgery was investigated in another 30 patients. The clotting assays and results of in-vivo platelet function tests indicated that both preparations produced similar effect. Intragroup comparisons, however, showed significant differences in the anti-factor Xa activity, lipoprotein lipase release, and plasma prekallikrein concentrations. A single injection of low-molecular-weight heparin daily is a convenient way of preventing deep vein thrombosis in high-risk patients undergoing major abdominal surgery. 相似文献

Objective To study and evaluate the treatment of the deep vein thrombosis(DVT) around the renal vein(DVT involving the renal vein and it’s surrounding,shortly as DVTAR in our study)by two-positioned filter for catheter thrombectomy assisted with a Fogarty balloon.Methods We retrospectivly analysed seven cases of DVTAR and by comparison to elicit the respective effect different methods in DVT treatment.The methods used were:1.direct thrombectomy 2.thrombectomy facillitated by blocking of blood flow with a balloon 3.direct thrombolysis via Peripheral vein and 4.thrombectomy with simultaneous placement of a two-positioned filter with a Fogarty balloon and followed by intubation thrombolysis.Result Segmental pulmonary embolism(PE)or thrombosis in vena cava were still observed by CT angiography(CTA)or venography in those cases treated with the first three methods.As for the 3 cases where two-positioned filter for catheter thrombectomy with Fogarty balloon was used,neither pulmonary embolism during and after the operation nor thrombosis in the inferior vena cava was observed.Conclusion For DVTAR,thrombectomy with simultaneous placement of a two-positioned filter with a Fogarty balloon and followed by intubation thrombolysis can be regarded as safe and effective. 相似文献

In the absence of thromboprophylaxis, venous thromboembolism (VTE) affects about 50 to 80% of the patients after total hip replacement (THR), total knee replacement (TKR), or hip fracture surgery. Since stratification of patients in those who will become symptomatic and those who will not, is not possible, primary high risk thromboprophylaxis should be provided to all patients undergoing major orthopedic surgery of the lower extremity. Various non-pharmacologic and pharmacologic thromboprophylactic measures have been evaluated. With regard to pharmacologic thromboprophylaxis unfractionated heparin has now almost completely been replaced by low molecular weight heparin (LMWH) for VTE prophylaxis. The use of acetylsalicylic acid for thromboprophylaxis in patients undergoing major orthopedic surgery of the lower extremities is not recommended. The optimal beginning of LMWH thromboprophylaxis is either 2 hours preoperatively or 6 to 8 hours postoperatively. Extended thromboprophylaxis (beyond 7 to 10 days after surgery) is recommended for high-risk patients. New antithrombotics, such as fondaparinux or (xi)melagatran, significantly reduce the risk of asymptomatic but not of symptomatic VTE compared to LMWH. In the light of other potential side effects (e.g., an increased bleeding risk) and high costs the role of these new drugs in the prophylaxis of VTE in patients undergoing major orthopedic surgery of the lower extremities remains to be established. 相似文献

下肢深静脉血栓形成(deep vein thrombosis of the lower extremity,DVT)是常见病、多发病,致残率高并有一定的死亡率。预防肺动脉栓塞,清除血栓,恢复下肢深静脉的通畅血流,保存静脉瓣膜功能,预防血栓复发是治疗急性DVT的理想目标。要达到这一目标,除卧床休息,抬高患肢等一般治疗外,还需采用抗凝、溶栓和手术取栓等多种方法治疗。 相似文献
