Compression garments for the management of pediatric post-thrombotic syndrome: A prospective longitudinal study.

Background: Graduated compression garments (CG) are a standard form of management of post-thrombotic syndrome (PTS) in adults, but data in children are lacking.

Objectives: We aimed to study the attitudes toward CG and change in PTS severity score in children who were prescribed CG for PTS management.

Methods: Children with PTS were enrolled in this longitudinal prospective study at the time of CG prescription. PTS severity was measured at baseline and follow-up using CAPTSure ; attitude toward CG was registered at follow-up.

Results: Forty-five patients were enrolled (median age 13 years, 25th-75th percentile 8-15 years; 53% male patients); 71% were prescribed socks and 29% sleeves; pressure was 15-20 mmHg in 84% of CG. Median baseline PTS CAPTSure score was 31 points (25th-75th percentile 21-45 points). At follow-up, 49% of patients found CG helpful, 27% found CG not helpful, and 16% did not buy or wear the CG. Eight percent of enrolled patients did not return for study follow-up. Ninety-five percent of the children who found CG helpful wore them for ≥3 days/week. Hours of CG wear at the time of follow-up were associated with lower PTS scores at follow-up in a non-linear manner (e.g., wearing 12 vs. 0 h/day was associated with a 16-point reduction in PTS scores at follow-up, 95% CI -29 to -2 points).

Conclusion: Nearly half the patients who were prescribed CG found them helpful. We observed non-linear improvement in PTS severity with the use of low-pressure CG for 8-12 h/day and ≥3 days/week, providing guidance in their prescription.
