Earlier this year1 we discussed the prevention and treatment of venous thrombosis and concluded that heparin in low dosage seemed the most promising drug for preventing deep-vein thrombosis postoperatively, although the optimum regimen was not yet known. Sharnoff and his associates who began this work 10 years ago claim to have shown that this treatment largely prevents fatal pulmonary embolism.2

ObjectivesTo evaluate the short-term (12 weeks) safety and utilisation of rivaroxaban prescribed to new-user adult patients for the treatment of deep vein thrombosis and pulmonary embolism and for the prevention of recurrent deep vein thrombosis and pulmonary embolism in a secondary care setting in England and Wales.DesignAn observational cohort study using the technique of Specialist Cohort Event Monitoring.SettingThe Rivaroxaban Observational Safety Evaluation study was conducted across 87 participating National Health Service secondary care trusts in England and Wales.Participants1532 patients treated with rivaroxaban for the prevention and treatment of deep vein thrombosis/pulmonary embolism from September 2013 to January 2016.InterventionsNon-interventional postauthorisation safety study of rivaroxaban.Primary and secondary outcome measures(1) Risk of major bleeding in gastrointestinal, intracranial, and urogenital sites and (2) risk of all major and clinically relevant non-major bleeds.ResultsOf a total of 4846 patients enrolled in the study from September 2013 to January 2016, 1532 were treated with rivaroxaban for the prevention and treatment of deep vein thrombosis/pulmonary embolism. The median age of the deep vein thrombosis/pulmonary embolism cohort was 63 years, and 54.6% were men. The risk of major bleeding within the gastrointestinal, urogenital and intracranial primary sites was 0.7% (n=11), 0.3% (n=5) and 0.1% (n=1), respectively. The risk of major bleeding in all sites was 1.5% (n=23) at a rate of 8.3 events per 100 patient-years.ConclusionsIn terms of the primary outcome risk of major bleeding in gastrointestinal, intracranial and urogenital sites, the risk estimates in the population using rivaroxaban for deep vein thrombosis/pulmonary embolism were low (<1%) and consistent with the risk estimated from clinical trial data and in routine clinical practice.Trial registration numbersClinicalTrials.gov Registry (NCT01871194); ENCePP Registry (EUPAS3979).

SummaryThe use of heparin as the most potent anticoagulant for the prevention of deep vein thrombosis and pulmonary embolism is nevertheless limited, because it is available to patients only by parenteral administration. Toward overcoming this limitation in the use of heparin, we have previously developed an orally active heparin-deoxycholic acid conjugate (LMWH-DOCA) in 10% DMSO formulation. The present study evaluates the anti-thrombogenic effect of this orally active LMWH-DOCA using a venous thrombosis animal model with Sprague-Dawley rats. When 5 mg/kg of LMWH-DOCA was orally administered in rats, the maximum anti-FXa activity in plasma was 0. 35 ± 0. 02, and anti-FXa activity in plasma was maintained above 0. 1 IU/ml [the minimum effective anti-FXa activity for the prevention of deep venous thrombosis (DVT) and pulmonary embolism (PE)] for five hours. LMWH-DOCA (5 mg/kg, 430 IU/kg) that was orally administered reduced the thrombus formation by 56. 3 ± 19. 8%;on the other hand, subcutaneously administered enoxaparin (100 IU/kg) reduced the thrombus formation by 36. 4 ± 14. 5%. Also, LMWH-DOCA was effectively neutralized by protamine that was used as an antidote. Therefore, orally active LMWH-DOCA could be proposed as a new drug that is effective for the longterm prevention of DVT and PE.

In recent years it has been repeatedly shown that low-dose subcutaneous heparin reduces the incidence of deep vein thrombosis (D.V.T.) after major general surgery. By comparison, the prevention of thrombosis in medical patients has been little studied. A randomised trial was undertaken in one hundred patients with heart failure and/or chest infection to determine whether low-dose subcutaneous heparin reduced the frequency of D.V.T. in the legs. Heparin (5000 units 8 hourly), started within 12 hours of admission to hospital and continued until the patient was fully mobile, significantly reduced the frequency of D.V.T. diagnosed by the 125I- fibrinogen scan technique, from 26% to 4% (p<0.01). Heparin did not cause bleeding problems except for a 20% incidence of injection site bruising. We therefore recommend prophylaxis with low dose subcutaneous heparin in patients with heart failure or chest infection who require more than 3 days’ bed rest.

Acute deep venous thrombosis (DVT) of iliofemoral segment is one of the most dreaded presentations of venous thromboembolism, as it can not only compromise the function of the extremity but may also result in pulmonary embolism and even death. There are many causes for acute iliofemoral DVT, including underdiagnosed May-Thurner syndrome, hypercoagulable syndrome, and external compression on iliocaval segment. The available treatment depends on the acuity of the symptoms. Acute iliofemoral DVT can be treated with medical anticoagulation, pharmacomechanical therapy, including thrombolysis or surgical thrombectomy. Chronic iliofemoral occlusion may be treated with recanalization of the occluded segments with angioplasty stenting. This review contains 4 Figures, 4 Tables and 63 references Key Words: acute, angioplasty, deep venous thrombosis, iliofemoral, inferior vena cava, pharmacomechanical therapy, occlusion, stent
