Insights
Catheter-directed thrombolysis (CDT) offers a more effective treatment for acute lower extremity deep vein thrombosis (DVT), leading to better outcomes. This approach significantly reduces the incidence of post-thrombotic syndrome (PTS) and improves vessel patency rates.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Cardiology
Background:
- Acute lower extremity deep vein thrombosis (DVT) poses significant risks, including post-thrombotic syndrome (PTS) and reduced limb function.
- Current treatment strategies aim to prevent clot propagation, reduce acute symptoms, and minimize long-term complications.
- Catheter-directed thrombolysis (CDT) is an emerging endovascular technique for acute DVT management.
Purpose of the Study:
- To systematically evaluate case series on catheter-directed thrombolysis (CDT) for acute lower extremity deep vein thrombosis (DVT).
- To compare the efficacy of CDT versus anticoagulation in managing acute lower extremity DVT.
- To assess key outcomes including patency rates, complete lysis, rethrombosis, and PTS incidence.
Main Methods:
- A comprehensive literature search was conducted across major databases (PubMed, Embase, Cochrane, Ovid MEDLINE, Scopus) up to January 2017.
- Inclusion criteria focused on acute lower extremity DVT patients treated with CDT or anticoagulation.
- Pooled estimates for efficacy outcomes and odds ratios for comparative studies were calculated using meta-analysis techniques.
Main Results:
- Analysis of 25 articles (2254 patients) revealed pooled outcomes for CDT: patency rate 0.87, complete lysis 0.58, rethrombosis 0.11, and PTS 0.10.
- Comparative studies (6 articles) demonstrated CDT significantly reduced PTS (OR 0.38) and increased patency rates (OR 4.76) compared to anticoagulation.
- These findings indicate a statistically significant benefit of CDT in managing acute DVT.
Conclusions:
- Catheter-directed thrombolysis (CDT) is an effective treatment for acute lower extremity DVT.
- CDT is associated with a lower incidence of post-thrombotic syndrome (PTS) and higher patency rates compared to anticoagulation.
- These results support the consideration of CDT as a primary treatment modality for selected patients with acute lower extremity DVT.
Objectives:
To evaluate case series studies that quantitatively assess the effects of catheter-directed thrombolysis (CDT) and compare the efficacy of CDT and anticoagulation in patients with acute lower extremity deep vein thrombosis (DVT).
Methods:
Relevant databases, including PubMed, Embase, Cochrane, Ovid MEDLINE and Scopus, were searched through January 2017. The inclusion criteria were applied to select patients with acute lower extremity DVT treated with CDT or with anticoagulation. In the case series studies, the pooled estimates of efficacy outcomes for patency rate, complete lysis, rethrombosis and post-thrombotic syndrome (PTS) were calculated across the studies. In studies comparing CDT with anticoagulation, summary odds ratios (ORs) were calculated.
Results:
Twenty-five articles (six comparing CDT with anticoagulation and 19 case series) including 2254 patients met the eligibility criteria. In the case series studies, the pooled results were a patency rate of 0.87 (95% CI: 0.85-0.89), complete lysis 0.58 (95% CI: 0.40-0.75), rethrombosis 0.11 (95% CI: 0.06-0.17) and PTS 0.10 (95% CI: 0.08-0.12). Six studies comparing the efficacy outcomes of CDT and anticoagulation showed that CDT was associated with a reduction of PTS (OR 0.38, 95%CI 0.26-0.55, p<0.0001) and a higher patency rate (OR 4.76, 95%CI 2.14-10.56, p<0.0001).
Conclusion:
Acute lower extremity DVT patients receiving CDT were found to have a lower incidence of PTS and a higher incidence of patency rate. In our meta-analysis, CDT is shown to be an effective treatment for acute lower extremity DVT patients.
