Post-thrombotic syndrome after upper extremity deep vein thrombosis: An international Delphi consensus study.

ABSTRACT:

Objectives

Primary deep vein thrombosis of the upper extremity (UEDVT) is a rare condition but up to 60% of patients may develop post-thrombotic syndrome in the upper extremity (UE-PTS) with significant morbidity and decreased quality of life. However, there is no universally accepted method to diagnose and classify UE-PTS, hampering scientific research on UEDVT treatment. Through this international Delphi consensus study we aimed to determine what a clinical score for diagnosing UE-PTS should entail.

Methods

An online focus group survey among 20 patients treated for UEDVT was performed to provide clinical parameters before the start of a four round electronic Delphi consensus study among 25 international experts. The CREDES recommendations on Conducting and Reporting Delphi Studies were applied. Open text questions, multiple selection questions, and 9-point Likert scales were used. Consensus was set at 70% agreement.

Results

After four rounds, agreement was reached on a composite score of five symptoms and three clinical signs, combined with a functional disability score. The signs and symptom will each be scored on a severity scale of 0-3 and the total score expressed as an ordinal variable; no/mild/moderate/or severe PTS. The functional disability portion measures the impact of the signs and symptoms on the functionality of the patient's arm.

Conclusion

Consensus was reached on a composite score of signs and symptoms of UE-PTS combined with a functional disability score. Clinical validation of the UE-PTS score in a large patient cohort is mandatory to facilitate application in future research.

Project description:BackgroundData on complications after upper extremity vein thrombosis (UEVT) are limited and heterogeneous.MethodsThe aim of the present study was to evaluate the pooled proportions of venous thromboembolism (VTE) recurrence, bleeding, and post-thrombotic syndrome (PTS) in patients with UEVT. A systematic literature review was conducted of PubMed, Embase, and the Cochrane Library databases from January 2000 to April 2023 in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. All studies included patients with UEVT and were published in English. Meta-analyses of VTE recurrence, bleeding, and of PTS after UEVT were performed to compute pooled estimates and associated 95% confidence intervals (CIs). Subgroup analyses of cancer-associated UEVT and catheter-associated venous thrombosis were conducted. Patients with Paget-Schroetter syndrome or effort thrombosis were excluded.ResultsA total of 55 studies with 15,694 patients were included. The pooled proportions for VTE recurrence, major bleeding, and PTS were 4.8% (95% CI, 3.8%-6.2%), 3.0% (95% CI, 2.2%-4.0%), and 23.8% (95% CI, 17.0%-32.3%), respectively. The pooled proportion of VTE recurrence was 2.7% (95% CI, 1.6%-4.6%) for patients treated with direct oral anticoagulants (DOACs), 1.7% (95% CI, 0.8%-3.7%) for patients treated with low-molecular-weight heparin (LMWH), and 4.4% (95% CI, 1.5%-11.8%) for vitamin K antagonists (VKAs; P = .36). The pooled proportion was 6.3% (95% CI, 4.3%-9.1%) for cancer patients compared with 3.1% (95% CI, 2.1%-4.6%) for patients without cancer (P = .01). The pooled proportion of major bleeding for patients treated with DOACs, LMWH, and VKAs, was 2.1% (95% CI, 0.9%-5.1%), 3.2% (95% CI, 1.4%-7.2%), and 3.4% (95% CI, 1.4%-8.4%), respectively (P = .72). The pooled proportion of PTS for patients treated with DOACs, LMWH, and VKAs was 11.8% (95% CI, 6.5%-20.6%), 27.9% (95% CI, 20.9%-36.2%), and 24.5% (95% CI, 17.6%-33.1%), respectively (P = .02).ConclusionsThe results from this study suggest that UEVT is associated with significant rates of PTS and VTE recurrence. Treatment with DOACs might be associated with lower PTS rates than treatment with other anticoagulants.

Project description:The cumulative incidence, risk factors, rate of subsequent venous thromboembolism (VTE) and bleeding and impact on mortality of isolated upper extremity deep vein thrombosis (UE DVT) in acute leukemia are not well-described. The California Cancer Registry, used to identify treated patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) diagnosed between 2009 and 2014, was linked with the statewide hospitalization database to determine cumulative incidences of UE DVT and subsequent VTE and bleeding after UE DVT diagnosis. Cox proportional hazards regression models were used to assess the association of UE DVT on the risk of subsequent pulmonary embolism (PE) or lower extremity deep vein thrombosis (LE DVT) and subsequent bleeding, and the impact of UE DVT on mortality. There were 5,072 patients identified: 3,252 had AML and 1,820 had ALL. Three- and 12-month cumulative incidences of UE DVT were 4.8% (95% confidence interval [CI]: 4.1-5.6) and 6.6% (95% CI: 5.8-7.5) for AML and 4.1% (95% CI: 3.2-5.1) and 5.9% (95% CI: 4.9-7.1) for ALL, respectively. Twelve-month cumulative incidences of subsequent VTE after an incident UE DVT diagnosis were 5.3% for AML and 12.2% for ALL. Twelve-month cumulative incidences of subsequent bleeding after an incident UE DVT diagnosis were 15.4% for AML and 21.1% for ALL. UE DVT was associated with an increased risk of subsequent bleeding for both AML (hazard ratio [HR]: 2.07; 95% CI: 1.60-2.68) and ALL (HR: 1.62; 95% CI: 1.02-2.57) but was not an independent risk factor for subsequent PE or LE DVT for either leukemia subtype. Isolated incident UE DVT was associated with increased leukemia-specific mortality for AML (HR: 1.42; 95% CI: 1.16-1.73) and ALL (HR: 1.80; 95% CI: 1.31-2.47). UE DVT is a relatively common complication among patients with AML and ALL and has a significant impact on bleeding and mortality. Further research is needed to determine appropriate therapy for this high-risk population.
