Leg vein size changes in the first two days after long flights to Bogota
Part of Blood & lymphatic, Heart & circulation clinical trials.
This study measures the size of a vein in your leg before, during, and after a long flight to Bogota. It aims to understand how flying affects that vein, which may help prevent blood clots. You must be flying to Bogota for at least 4 hours and be willing to have several vein ultrasounds.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You are flying to Bogota, and the flight lasts 4 hours or more.
- You are available for leg ultrasound exams before your flight, within 2 hours after arrival, and at 24 and 48 hours after arrival.
- You do not have a current blood clot in your leg or lungs.
- You are not taking blood-thinning medication (anticoagulants).
- You have not had major leg surgery, have no active leg infection, and have no condition that prevents an ultrasound of your leg.

This study looks at how flying in premium versus economy class affects the size of a leg vein (the popliteal vein) after a long flight, which may help understand blood clot risk during travel. It compares people who fly in either cabin class before having an aesthetic surgery.
This study looks at how different seating classes (business/first vs. economy) and wearing compression stockings on long flights affect leg vein swelling after cosmetic surgery. Participants will have an ultrasound to check the veins before and after the flight.
This trial tests whether wearing a certain type of compression stocking during a long economy-class flight helps prevent veins in the legs from widening after plastic surgery. If you are planning such a trip, the study may help you recover more safely and comfortably.
This study measures the properties of human saphenous and popliteal veins. If you’re having certain lower-leg procedures, your care team may collect information to better understand vein function and support future treatment.
This study uses a device that gently presses on your calf to check blood flow in leg veins, along with an ultrasound you already had. It may help doctors better understand vein blockages.
This study uses an ultrasound to measure the size of a vein in your leg before surgery to see if it can predict a drop in blood pressure during the procedure. If you are over 60 and having planned lower-limb surgery with spinal anesthesia, this non-invasive test might help your doctors prepare for your care.
