Recurrent Thromboembolism (recurrent + thromboembolism)
Selected AbstractsPost-thrombotic syndrome, recurrence, and death 10 years after the first episode of venous thromboembolism treated with warfarin for 6 weeks or 6 monthsJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 4 2006S. SCHULMAN Summary.,Background: The influence of the duration of anticoagulant therapy after venous thromboembolism (VTE) on the long-term morbidity and mortality is unclear. Aim: To investigate the long-term sequelae of VTE in patients randomized to different duration of secondary prophylaxis. Methods: In a multicenter trial comparing secondary prophylaxis with vitamin K antagonists for 6 weeks or 6 months, we extended the originally planned 2 years follow-up to 10 years. The patients had annual visits and at the last visit clinical assessment of the post-thrombotic syndrome (PTS) was performed. Recurrent thromboembolism was adjudicated by a radiologist, blinded to treatment allocation. Causes of death were obtained from the Swedish Death Registry. Results: Of the 897 patients randomized, 545 could be evaluated at the 10 years follow-up. The probability of developing severe PTS was 6% and any sign of PTS was seen in 56.3% of the evaluated patients. In multivariate analysis, old age and signs of impaired circulation at discharge from the hospital were independent risk factors at baseline for development of PTS after 10 years. Recurrent thromboembolism occurred in 29.1% of the patients with a higher rate among males, older patients, those with permanent triggering risk factor , especially with venous insufficiency at baseline , signs of impaired venous circulation at discharge, proximal deep vein thrombosis, or pulmonary embolism. Death occurred in 28.5%, which was a higher mortality than expected with a standardized incidence ratio (SIR) of 1.43 (95% CI 1.28,1.58), mainly because of a higher mortality than expected from cancer (SIR 1.83; 95% CI 1.44,2.23) or from myocardial infarction or stroke (SIR 1.28; 95% CI 1.00,1.56). The duration of anticoagulation did not have a statistically significant effect on any of the long-term outcomes. Conclusion: The morbidity and mortality during 10 years after the first episode of VTE is high and not reduced by extension of secondary prophylaxis from 6 weeks to 6 months. A strategy to reduce recurrence of VTE as well as mortality from arterial disease is needed.

By percutaneous closure of PFO, surgical closure or permanent oral anticoagulation can be avoided. So far, published series included different occluder systems and various indications and regimens of postprocedural anticoagulation. The aim of the present study was to evaluate the short- and long-term results after implantation of the Starflex® occluder in patients with PFO using an intensified anticoagulation regimen. Methods and Results:154 patients with PFO (94 men; age: 44 ± 13 years) and >1 thromboembolic event were included. Other causes for embolism were excluded. PFO closure was successful in 147 patients (95.5%). All patients were treated with phenprocoumon (INR 2.5) and aspirin (100 mg/die) for 6 months. Transesophageal echocardiography (TEE) was repeated at 6 months. Mean clinical follow-up period was 26 ± 18 months. After 6 months, five patients had a significant residual shunt, and five patients had suspected thrombus formation on the occluder. In three of these five patients, the occluder was surgically removed and foreign body reaction was noted. During follow-up, nine patients suffered from neurological events (two strokes, seven transient ischemic attacks [TIA]), though complete closure of the PFO was documented by TEE. Two patients died during follow-up; three patients had bleeding complications. Conclusion:Percutaneous closure of PFO in symptomatic patients by Starflex® occluder represents an effective therapy with a low incidence of periinterventional complications and recurrent thromboembolism. However, thrombus formation at the occluder system may occur in some patients despite an aggressive anticoagulation regimen.
