Unveiling the complexities of catheter-related thrombosis: risk factors, preventive strategies, and management

Area of Science:

• Vascular Medicine
• Thrombosis Research
• Clinical Guidelines

Background:

• Catheter-related deep venous thrombosis (CR-DVT) is a frequent complication of central venous catheters.
• Current prophylactic and treatment strategies for CR-DVT lack definitive evidence and standardized guidelines.

Purpose of the Study:

• To review the epidemiology, risk factors, and current management strategies for CR-DVT.
• To discuss diagnostic, prophylactic, and treatment options, including novel anticoagulants.
• To propose an individualized approach to CR-DVT prevention and management.

Main Methods:

• Comprehensive literature review of CR-DVT, including observational studies and randomized trials.
• Analysis of existing guideline recommendations for CR-DVT treatment.
• Exploration of future research directions and advances in anticoagulation.

Main Results:

• Data on CR-DVT prophylaxis and treatment are heterogeneous, often from small studies or extrapolated from lower extremity DVT trials.
• Guidelines suggest limited anticoagulation post-catheter removal or continuous anticoagulation if the catheter remains functional.
• A significant need exists for large, randomized controlled trials to establish optimal management, particularly for high-risk bleeding patients.

Conclusions:

• Optimal strategies for CR-DVT prevention and treatment require further definition through robust clinical trials.
• An individualized approach, considering patient-specific factors and bleeding risk, is crucial for current management.
• Novel anticoagulants may offer future therapeutic options for CR-DVT.
