Functional impact of pediatric postthrombotic syndrome

Area of Science:

• Pediatric Medicine
• Vascular Health
• Rehabilitation Science

Background:

• Postthrombotic syndrome (PTS) is a frequent complication following deep vein thrombosis (DVT) in pediatric populations.
• Understanding the functional consequences of PTS in children is crucial for effective management and improving quality of life.

Purpose of the Study:

• To evaluate the impact of pediatric PTS on various aspects of functioning, including movement ability, mobility, functional disability, and physical activity.
• To determine the association between the severity of PTS and these functional outcomes in children diagnosed with limb DVT.

Main Methods:

• A cross-sectional study involving 87 children (aged 8-21 years) with a history of limb DVT.
• Functioning was assessed using validated self-reported questionnaires measuring movement ability, mobility, functional disability, and physical activity levels.
• PTS severity was quantified using the index for the Clinical Assessment of PTS in children, with linear models used for analysis.

Main Results:

• Increased PTS severity correlated with reduced current movement ability and a greater discrepancy between current and preferred movement.
• Children with more severe PTS exhibited lower mobility scores and slightly increased functional disability.
• No significant association was found between PTS severity and moderate-to-strenuous physical activity levels.

Conclusions:

• In pediatric patients, greater PTS severity is linked to diminished movement ability and impaired mobility.
• Strategies aimed at reducing the gap between perceived and desired movement ability are important components of managing PTS in children.
