Insights
Deep vein thrombosis (DVT) classification into isolated distal (iDDVT), isolated proximal (iPDVT), or mixed types showed similar long-term outcomes. Baseline characteristics did not significantly predict DVT type, with leg injury being higher in iDDVT.
Area of Science:
- Medical research
- Vascular medicine
- Thrombosis
Background:
- Deep vein thrombosis (DVT) is a significant cause of mortality and morbidity.
- DVT classification includes isolated distal DVT (iDDVT), isolated proximal DVT (iPDVT), and mixed DVT.
- Understanding differences in baseline characteristics and outcomes across DVT types is crucial for patient management.
Purpose of the Study:
- To investigate the baseline characteristics of patients with different DVT classifications.
- To assess and compare clinical outcomes, including recurrent DVT, major bleeding, rehospitalization, and mortality, among iDDVT, iPDVT, and mixed DVT groups.
Main Methods:
- Retrospective study analyzing data from 493 patients experiencing their first DVT event.
- Patients were categorized into iDDVT, iPDVT, or mixed DVT groups based on clot location and extent.
- Outcomes assessed included recurrent DVT, major bleeding (MB), VTE-related rehospitalization, and DVT-related inpatient mortality at 12 months.
Main Results:
- The study included 273 (55.4%) iPDVT, 25 (5.1%) iDDVT, and 195 (39.6%) mixed DVT patients.
- Leg injury was a significantly more common etiology in iDDVT (24%) compared to iPDVT (6.2%) and mixed DVT (5.6%).
- At 12 months, overall recurrent DVT was 9.9%, with similar rates across groups (iPDVT 9.2%, iDDVT 12.0%, mixed DVT 10.8%). Rates of MB, re-hospitalization, and DVT-related death were also similar.
Conclusions:
- No significant association was found between baseline characteristics and the development of specific lower extremity DVT types.
- Clinical outcomes, including recurrence, bleeding, rehospitalization, and mortality, are comparable across isolated distal, isolated proximal, and mixed DVT classifications.
Abstract:
Background: Deep vein thrombosis (DVT) is a leading cause of death disability. DVT can be classified based on the location and extent of the clot into isolated distal DVT (iDDVT), isolated proximal DVT (iPDVT), or mixed DVT. The aim of this study is to explore the baseline characteristics and clinical outcomes of patients with different types of DVT. Methods: This was a retrospective study of patients who experienced their first DVT event and received an anticoagulant for management. The outcomes of this study include evaluating patients' characteristics for patients with DVT and assessing the incidence of recurrent DVT, major bleeding (MB), VTE-related rehospitalization, and DVT-related inpatient mortality across different types of DVT. Results: A total of 493 patients were included in the study. Of those, 273 (55.4%) had iPDVT, 25 (5.1%) had iDDVT, and 195 (39.6%) had mixed DVT. The VTE etiology was similar across the groups except for the leg injury, which was significantly higher in patients with iDDVT (24%) compared to iPDVT (6.2%) and mixed DVT (5.6%) (P = .002). At 12 months, a total of 49 patients (9.9%) had a recurrent DVT event; 25 (9.2%) in the iPDVT group, 3 (12.0%) in the iDDVT group, and 21 (10.8%) in the mixed DVT group (P = .797). Rates of MB, re-hospitalization, and death from DVT were similar between the groups. Conclusion: Baseline characteristics were not significantly linked to the risk of developing a specific type of lower extremity DVT. Long-term outcomes were similar across all DVT types.
