Q. Are long flights dangerous? I'm flying next week to my vacation, and the flight is going to be rather long (almost 16 hours non-stop). Several years ago, my 75 years-old aunt had blood clot in her lung after a flight of similar length. I also heard that during flight the blood in the legs clots and that it can cause after that problems with the lungs and breathing. Does this mean it's dangerous for me to fly? Should I change my ticket to shorter connection flights?

A. Do other relatives of yours have blood clotting problems too, like your aunt? You should tell a doctor about the problem your aunt had and ask if it's genetic.

A la fecha se sabe que si bien la superposicion de los vasos es anatomicamente normal, en algunos pacientes el efecto que genera la compresion posterior de la vena con el cuerpo vertebral y la compresion anterior con la arteria iliaca induce dos mecanismos, el primero la obstruccion mecanica al flujo y el segundo la hiperplasia intimal y la formacion de membranas o bandas de elastina y colageno (1, 6) como consecuencia de la transmision de la fuerza pulsatil cronica desde la arteria que ocasiona friccion entre las paredes de la vena (7).
