Determinants of Late Venous Thromboembolic Events After Acute Isolated Superficial Vein Thrombosis in Daily Practice: 12 Month Results of the INSIGHTS-SVT Study.
Long term incidence of symptomatic venous thromboembolism (VTE) and bleeding events in patients with superficial vein thrombosis (SVT) was investigated.. In this prospective, observational study, patients with acute SVT were treated at the discretion of the responsible physician. The primary efficacy outcome was symptomatic VTE including deep vein thrombosis (DVT), pulmonary embolism (PE), and recurrent or extending SVT. The primary safety outcome was clinically relevant bleeding, recorded at periodic clinic visits over a 12 month period.. The mean age of 872 patients with 12 month follow up was 60.6 ± 14.5 years, 64.5% were female, 80.1% had chronic venous disease (defined as chronic venous insufficiency and or varicose veins), and 41.9% had a history of VTE. They were receiving fondaparinux in 62.1% (mean duration 34.9 ± 15.7 days), low molecular weight heparin (LMWH) in 25.0% (mean duration 26.2 ± 23.2 days), any other anticoagulants in 6.2%, and no anticoagulant in 6.7%. At 12 months, 108 patients (14.3%) achieved the primary efficacy outcome. The most common VTE event was recurrent or extending SVT in 11.0%, followed by symptomatic DVT in 2.7%, symptomatic PE in 2.4%, hospitalisation due to VTE in 1.8%, and death in 1.1%. Clinically relevant bleeding events occurred in 2.1% of patients, and major bleedings in 0.3%. By drug, the rate of the primary efficacy outcome was highest in the LMWH group (22.4%) and lowest in the fondaparinux group (10.4%). In a multivariable model, patients with events between three months and 12 months were significantly more likely to have higher BMI (hazard ratio [HR] 1.06; p = .002), history of VTE (HR 2.89; p = .002), and severe systemic infections (HR 7.59; p = .006).. The risk of symptomatic VTE remained elevated over 12 months of follow up. Therefore, anticoagulation beyond 45 days may be considered in patients with risk factors.

Management and Outcomes of Patients with Isolated Superficial Vein Thrombosis under Real Life Conditions (INSIGHTS-SVT).
Management and outcomes of superficial vein thrombosis (SVT) are highly variable and not well described. Therefore, the INvestigating SIGnificant Health TrendS in the management of SVT (INSIGHTS-SVT) study collected prospective data under real life conditions.. Prospective observational study of objectively confirmed acute isolated SVT. The primary outcome was a composite of symptomatic deep vein thrombosis (DVT), pulmonary embolism (PE), and extension or recurrence of SVT at three months. The primary safety outcome was clinically relevant bleeding.. A total of 1 150 patients were included (mean age 60.2 ± 14.7 years; 64.9% women; mean BMI 29.4 ± 6.3 kg/m. At three month follow up, patients with isolated SVT are at risk of thromboembolic complications (mainly recurrent or extended SVT), despite anticoagulation. In this real life study, about one third had received either heparins, oral anticoagulants, or no anticoagulation.

Duration of pharmacological thromboprophylaxis after outpatient endovenous laser ablation: a propensity score-matched analysis.
The objective of this study was to identify the optimal duration of pharmacological thromboprophylaxis after outpatient endovenous laser ablation (EVLA).. In this multicentre retrospective study in a university hospital, regional hospital and private practices, we collected the demographic, procedural and outcome data of all consecutive patients with varicose veins class C2 to C6 undergoing outpatient EVLA of truncal and accessory veins between February 2009 and December 2015. The cumulative primary efficacy endpoint consisted of endovenous heat-induced thrombosis (EHIT) class 2–4, deep vein thrombosis (DVT) and pulmonary embolism (PE) diagnosed with duplex ultrasound or computed tomography angiography after 1 and 4 weeks of follow-up. Cumulative secondary endpoints were complete ablation of the treated veins and major bleeding, skin burns and infection.. A total of 864 patients were treated with EVLA as an outpatient procedure. Of those, 35 patients were omitted because of therapeutic anticoagulation or dual antiplatelet therapy. Another 36 cases were excluded as the patients received pharmacological thromboprophylaxis for 5 days. A total of 793 were included in the final analysis. Of those, 225 patients (28.4%) received fondaparinux 2.5 mg s.c. for 3 days, 166 patients (20.9%) received rivaroxaban 10 mg p.o. for 3 days and 402 patients (50.7%) received rivaroxaban 10 mg for 10 days. The incidence of EHIT class 2–4 was 0.8% (n = 6) in total, 1.3% (n = 6) in group 1 (treated for 3 days) and 0.3% (n = 1) in group 2 (treated for 10 days) (odds ratio [OR] 0.19, confidence interval [CI] 0.02–1.66, p = 0.133). The cumulative primary composite endpoint at 4-week follow-up was 1.1% (n = 9) and was 2.1% (n = 8) in group 1 and 0.3% (n = 1) in group 2 (OR 0.0.12, CI 0.01–0.96, p = 0.046). Propensity score-matched analysis revealed no significant difference in the composite primary endpoint (CI −0.074 to 0.26). Complete occlusion rate was 99.2% in group 1 and 98.8% in group 2 (OR 0.61, CI 0.15–2.59, p = 0.506). No PE or major bleeding events occurred in either group. Propensity score-matched analysis showed no significant difference in the secondary endpoints.. Using propensity score-matched analysis we showed that pharmacological thromboprophylaxis after EVLA seems to be equally effective with 3 days or 10 days of treatment with a similar success rate and safety profile. Undoubtedly, a large randomised control trial, ideally including a group without pharmacological thromboprophylaxis, is needed to draw more definitive conclusions on the optimal duration of pharmacological post-EVLA thromboprophylaxis.

Rivaroxaban versus fondaparinux for thromboprophylaxis after endovenous laser ablation.
Endovenous heat-induced thrombosis (EHIT) and deep venous thrombosis (DVT) are well-known complications after superficial endovenous thermoablation. We investigated the efficacy of rivaroxaban in preventing EHIT and DVT after endovenous laser ablation (EVLA).. We retrospectively analyzed a consecutive series of patients presenting with truncal varicosis class C. Between February 2009 and December 2015, 391 patients (473 limbs) were treated with EVLA of the truncal saphenous vein. The primary end point occurred in 13 of 166 (7.8%) and 14 of 225 (6.2%) after 1 week and in 13 of 166 (7.8%) and 15 of 225 (6.7%) after 4 weeks comparing the rivaroxaban and fondaparinux groups (P = .659). EHIT class 1 was observed in 20 patients (5.1%) and EHIT class 2 in five (1.3%). No patients had EHIT class 3 or 4. The incidence of DVT was one of 166 (0.6%) in the rivaroxaban group and two of 225 (0.9%) in the fondaparinux group (P = .750). Minor bleeding events occurred in 17 of 166 patients (10.2%) and in 20 of 225 patients (8.9%), respectively (P = .652). No major bleeding events were observed. Paresthesia was observed in 12.5% in the rivaroxaban group and in 17.8% in the fondaparinux group. No skin burns were observed.. Rivaroxaban offers an oral medication approach showing no difference in preventing EHIT and DVT compared with fondaparinux, without increased bleeding risk.
