Ruling out deep vein thrombosis in patients with superficial vein thrombosis: external validation of the ICARO score
Value of a Planned Compression Ultrasonography after an Isolated Superficial Vein Thrombosis: Results from a Prospective Multicentre Study
AbstractObjectivesTo assess the efficiency of a systematically planned compression ultrasonography (SP-CUS) to detect venous thrombotic complications (VTCs) in patients with symptomatic isolated superficial vein thrombosis (SVT).DesignPost hoc analysis of a prospective, multicentre, cohort study (POST).PatientsAs many as 537 patients with CUS-confirmed isolated SVT undergoing an SP-CUS 8â15 days after the initial CUS.OutcomesAsymptomatic VTC (extension or recurrence of SVT, deep-vein thrombosis (DVT) of the lower limbs) diagnosed by the SP-CUS and symptomatic thromboembolic complications (VTC and pulmonary embolism (PE)) up to 3 months.ResultsVTC was suspected before or on the day of the SP-CUS in 18 patients (3.0%). Among the 519 asymptomatic patients (97%) undergoing SP-CUS, this revealed asymptomatic VTC in 12 patients (2.3%; 4 DVT, 4 SVT recurrences, 4 SVT extensions), none of whom subsequently experienced symptomatic thromboembolic events up to 3 months. Among the 507 patients with a normal SP-CUS, 29 (5.7%) presented symptomatic thromboembolic events during follow-up: 2 PE, 7 DVT, 9 SVT recurrences and 11 SVT extensions.ConclusionsIn this study, the SP-CUS detected a few asymptomatic VTC, but failed to identify patients at risk of thromboembolic events during follow-up. Use of an SP-CUS was therefore neither efficient nor cost effective

Value of a Planned Compression Ultrasonography after an Isolated Superficial Vein Thrombosis: Results from a Prospective Multicentre Study
Fondaparinux for the treatment of superficial-vein thrombosis in the legs.
BACKGROUND: The efficacy and safety of anticoagulant treatment for patients with acute, symptomatic superficial-vein thrombosis in the legs, but without concomitant deep-vein thrombosis or symptomatic pulmonary embolism at presentation, have not been established.
METHODS: In a randomized, double-blind trial, we assigned 3002 patients to receive either fondaparinux, administered subcutaneously at a dose of 2.5 mg once daily, or placebo for 45 days. The primary efficacy outcome was a composite of death from any cause or symptomatic pulmonary embolism, symptomatic deep-vein thrombosis, or symptomatic extension to the saphenofemoral junction or symptomatic recurrence of superficial-vein thrombosis at day 47. The main safety outcome was major bleeding. The patients were followed until day 77.
RESULTS: The primary efficacy outcome occurred in 13 of 1502 patients (0.9%) in the fondaparinux group and 88 of 1500 patients (5.9%) in the placebo group (relative risk reduction with fondaparinux, 85%; 95% confidence interval [CI], 74 to 92; P<0.001). The incidence of each component of the primary efficacy outcome was significantly reduced in the fondaparinux group as compared with the placebo group, except for the outcome of death (0.1% in both groups). The rate of pulmonary embolism or deep-vein thrombosis was 85% lower in the fondaparinux group than in the placebo group (0.2% vs. 1.3%; 95% CI, 50 to 95; P<0.001). Similar risk reductions were observed at day 77. A total of 88 patients would need to be treated to prevent one instance of pulmonary embolism or deep-vein thrombosis. Major bleeding occurred in one patient in each group. The incidence of serious adverse events was 0.7% with fondaparinux and 1.1% with placebo.
CONCLUSIONS: Fondaparinux at a dose of 2.5 mg once a day for 45 days was effective in the treatment of patients with acute, symptomatic superficial-vein thrombosis of the legs and did not have serious side effects. (Funded by GlaxoSmithKline; ClinicalTrials.gov number, NCT00443053.
