Insights
Venous thromboembolism (VTE) causes significant mortality and recurrence. This review details chronic VTE complications like postthrombotic syndrome and pulmonary hypertension, summarizing their epidemiology, diagnosis, and treatment.
Area of Science:
- Cardiovascular Medicine
- Hematology
Background:
- Venous thromboembolism (VTE) affects ~700 per 100,000 individuals annually.
- VTE is linked to high recurrence rates, chronic complications, and mortality up to 40% at 10 years.
- Current anticoagulant therapies have improved acute VTE treatment but not chronic complication management.
Purpose of the Study:
- To provide a comprehensive review of VTE-related chronic complications.
- To summarize the epidemiology, diagnosis, and treatment strategies for postthrombotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension (CTEPH).
Main Methods:
- Literature review of VTE chronic complications.
- Synthesis of epidemiological data on PTS and CTEPH.
- Analysis of current diagnostic and therapeutic approaches.
Main Results:
- Impaired thrombus resolution underlies VTE complications, including PTS and CTEPH.
- PTS affects up to 50% of patients post-deep vein thrombosis.
- CTEPH diagnosis is less defined, affecting a smaller patient subset post-pulmonary embolism.
Conclusions:
- Chronic complications significantly impact VTE patient morbidity and healthcare costs.
- Further research is needed for effective prevention and treatment of VTE-related chronic conditions.
- A unified approach to managing VTE complications is essential.
Abstract:
Venous thromboembolism (VTE) is a common disease (~700 per 100 000) that is associated with significant risk of recurrence, chronic complications, and substantial mortality, with reported death rates of up to 40% at 10 years. The development of novel anticoagulants has revolutionized the treatment of acute VTE, while strategies for prevention and treatment of chronic complications still seek for such a landmark change. Impaired thrombus resolution is the common denominator behind VTE complications, which are postthrombotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension (CTEPH). PTS and CTEPH are associated with substantial morbidity and high healthcare expenses. While PTS occurs in up to 50% of patients after symptomatic deep vein thrombosis, only a small and poorly defined number of patients are diagnosed with CTEPH after pulmonary embolism. This review is a comprehensive summary of VTE-related chronic complications, their epidemiology, diagnosis, and treatment.
