Analysis of noncatheter-associated upper extremity deep venous thrombosis from the RIETE registry.

We sought to determine the risk factors for subsequent bleeding and recurrent venous thromboembolism (VTE) events following isolated noncatheter-associated upper extremity deep venous thrombosis (non-CA-UEDVT) to better inform future treatment decisions for this group of patients. The RIETE registry (Registro Informatizado de Enfermedad TromboEmbólica [Computerized Registry of Patients with Venous Thromboembolism]) is a prospective international registry of patients with objectively confirmed symptomatic VTE. Patients with a symptomatic, isolated, proximal UEDVT from March 2001 through March 2015 were analyzed. Any patient with an indwelling catheter or pacemaker lead at the DVT site and at the time of thrombosis was considered to have a CA-UEDVT and was excluded. Patient and treatment characteristics such as age, gender, comorbidities, VTE risk factors, treatment drug, and duration were collected. Outcomes examined included recurrent DVT, subsequent pulmonary embolism (PE), and hemorrhage. Multivariate analysis was performed using stepwise logistic regression. Of the 1100 patients who met the study criteria, 580 (53%) were male. The mean age of the patients was 50 ± 20 years, and overall patient survival at 1 year was 85%. Recurrent VTE occurred in 59 patients (5.4%). Of these, 46 patients (4%) had recurrent DVT, 10 (0.9%) had a PE following UEDVT diagnosis, and 3 (0.3%) had both. PE was fatal in three patients (0.3%). Bleeding occurred in 50 patients (4.5%), major bleeding in 19 patients (1.7%), and fatal bleeding in 6 patients (0.5%). On multivariate analysis, malignant disease was associated with VTE recurrence (odds ratio [OR], 2.00; 95% confidence interval [CI], 1.04-3.45; P < .04), whereas hemorrhage was associated with age (OR, 1.03; 95% CI, 1.01-1.05; P = .002) and malignant disease (OR, 2.53; 95% CI, 1.34-4.76; P < .005). Hemorrhage and recurrent VTE were also significantly associated (OR, 2.79; 95% CI, 1.16-6.76; P < .03). PE following non-CA-UEDVT is rare. Malignant disease was associated with VTE recurrence. Age and malignant disease were associated with hemorrhage, and VTE recurrence was associated with hemorrhage. Further prospective studies should be undertaken to best determine length of anticoagulation treatment for the varied populations of patients with UEDVT.

A RIETE registry analysis of recurrent thromboembolism and hemorrhage in patients with catheter-related thrombosis.

Few studies have investigated the treatment and the outcomes of patients with catheter-related thrombosis (CRT). The RIETE registry (Registro Informatizado de Enfermedad TromboEmbólica [Computerized Registry of Patients with Venous Thromboembolism]) is a prospective international registry of consecutive patients with objectively confirmed venous thromboembolism (VTE). We analyzed the characteristics, treatment, and outcomes of patients with CRT. Of 558 patients with CRT, 45 (8%) presented with a pulmonary embolism (PE) concomitantly. More patients had central line-associated thrombosis compared with port systems, but catheter type did not influence the risk of presenting with a PE. Patients with only CRT were more often prescribed low-molecular-weight heparin for the duration of their anticoagulant treatment compared with patients presenting with concomitant PE. VTE recurrences and major bleeding events occurred frequently during treatment with anticoagulation (7 per 100 patient-years and 8.9 per 100 patient years, respectively). The rates of fatal PE recurrences (1.85 per 100 patient-years) and fatal bleeding (2.32 per 100 patient-years) were similar. Patients with an additional transient risk factor for VTE had the lowest risk for VTE recurrences (odds ratio [OR], 0.07; 90% confidence interval [CI], 0.01-0.45) compared with patients with CRT and no additional transient risk factors. PE at presentation increased the risk of recurrent thrombosis by 2.4 times. Renal insufficiency was also an independent predictor of recurrent thrombosis (OR, 3.93; 90% CI, 2.0-7.7). The odds of recurrent thrombosis was decreased by 77% in patients who received anticoagulation therapy for >90 days compared with patients with a shorter treatment (OR, 0.23; 90% CI, 0.1-0.56). Concomitant PE occurs less frequently in CRT than lower extremity deep venous thrombosis, but it is associated with a worse outcome. CRT occurs in high-risk patients, and duration of anticoagulation must be predicated on balancing these risks.

Recurrence of venous thromboembolism in patients with recent gestational deep vein thrombosis or pulmonary embolism: Findings from the RIETE Registry.

The aim of this study was to investigate the recurrence rate of venous thromboembolism (VTE) and the prevalence of major bleeding or death in patients with previous VTE in pregnancy and puerperium. Risk factors for VTE recurrence were also assessed. We evaluated a cohort of patients enrolled in the international, multicenter, prospective Registro Informatizado de la Enfermedad Trombo-Embólica (RIETE) registry with objectively confirmed VTE. In the registry, 607 women were presenting with VTE that occurred during pregnancy or puerperium. The 2-year VTE recurrence rate was 3.3% (CI: 95 1.5-5.0%) and the recurrent VTE incidence rate was 2.28events/100 patients-year. Among the 16 cases of VTE recurrence 11 cases appeared during drug treatment while only five cases were diagnosed after therapy discontinuation. No significant difference was found in treatment duration among these two subgroups of VTE recurrence cases and women without recurrence. Furthermore, the use of thrombolytics and inferior vena cava filter in initial treatment was associated to an increased risk of VTE recurrence. The current study provides new insights on VTE recurrence rate in patients with deep vein thrombosis (DVT) or pulmonary embolism (PE) that occurred in pregnancy or postpartum period. These findings can contribute to risk assessment of thrombotic burden, thereby allowing for better decision making regarding antithrombotic management in this clinical setting.
