Moderate knee-high compression stockings for reducing popliteal vein dilation during long-haul flights after cosmetic surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, assessor-masked trial compares wearing knee-high graduated compression stockings versus no stockings in adults undergoing long-haul economy-class travel to Bogota after aesthetic surgery. Participants are assigned before departure and receive standardized preflight and postarrival duplex ultrasounds to measure popliteal vein diameter and cross-sectional area at baseline, arrival, 24 hours, and 48 hours. An intention-to-treat analysis with mixed models will estimate immediate and persistent effects of compression on venous dilation, while also recording adherence, movement, hydration, symptoms, and skin effects. The study uses enoxaparin, stockings, and standardized ultrasound protocols to assess whether compression reduces venous dilation during air travel in this setting.
