Screening ultrasound for deep vein thrombosis detection in high-risk pediatric trauma
Topic overview
Multi-center study of 460 high-risk pediatric trauma patients found that screening ultrasound at 7 days post-injury detected asymptomatic DVT in 15.6% of patients, with 90% associated with central lines. Most DVTs occurred in patients without timely chemical prophylaxis, though clinical significance of asymptomatic detection remains unclear.
Key takeaways
- Screening ultrasound at 7 days post-injury detected DVT in 15.6% of high-risk pediatric trauma patients, mostly asymptomatic.
- 90% of detected DVTs were associated with central venous lines, highlighting catheter-related thrombosis risk.
- DVTs occurred more frequently when chemical prophylaxis was delayed >24 hours or not given at all.
- Most DVTs in high-risk pediatric trauma occur within the first week of injury.
- Clinical significance of asymptomatic DVT detection by screening ultrasound remains uncertain.
