Prospective Comparative Cohort Study of Premium Versus Economy Cabin Travel and Popliteal Vein Diameter After Long-Haul Flight After an Aesthetic Surgery
Sponsor: Research Inc
Summary
This prospective cohort study will compare popliteal vein diameter changes in international travelers who independently fly to Bogota in premium business/first class or economy class. Standardized bilateral ultrasound will be performed before flight, within 2 hours after arrival, and at 24 and 48 hours. The primary outcome is the adjusted between-group difference in change from preflight diameter to arrival. Travel behavior and venous-risk confounders will be measured prospectively.

Conditions
Interventions
Premium Cabin Air Travel Exposure
Preexisting travel exposure defined by the cabin actually flown. Seat pitch, recline, lie-flat capability, aisle/window position, and ambulation opportunities will be recorded. Linked arm/group(s): Premium Cabin Travelers.
Economy Cabin Air Travel Exposure
Preexisting economy-cabin exposure with documentation of seat characteristics, position, movement, hydration, and other travel behaviors. Linked arm/group(s): Economy Cabin Travelers.
Standardized Bilateral Popliteal Vein Ultrasound
Triplicate anteroposterior and transverse diameter and cross-sectional-area measurements in both legs after a standardized resting period, with compressibility and flow assessment. Linked arm/group(s): Premium Cabin Travelers, Economy Cabin Travelers.
