Randomized Assessor-Masked Trial of Moderate Graduated Compression Stockings for Popliteal Vein Dilation During Long-Haul Economy-Class Air Travel After Aesthetic Surgery
Sponsor: Research Inc
Summary
This randomized assessor-masked trial will evaluate whether knee-high moderate graduated compression stockings reduce popliteal vein dilation during long-haul economy-class air travel to Bogota. Participants will be assigned to stockings or no stockings and will undergo bilateral ultrasound before flight, within 2 hours after arrival, and at 24 and 48 hours. The primary outcome is the between-group difference in change in mean bilateral popliteal vein diameter from preflight baseline to arrival.

Knee-High Graduated Compression Stockings
PROPOSED pressure class: 20-30 mmHg at the ankle, appropriately sized according to calf and ankle circumference, worn from approximately 1 hour before boarding until completion of the arrival ultrasound. The final product, pressure class, fitting method, and wear instructions must be confirmed. Linked arm/group(s): Moderate Compression Stockings.
Standardized Bilateral Popliteal Vein Ultrasound
Triplicate bilateral diameter and cross-sectional-area measurements after a standardized rest period, with compressibility and flow assessment by an assessor masked to allocation. Linked arm/group(s): Moderate Compression Stockings, No Compression Stockings.
