DVT is otherwise known as "Coach-Class Syndrome" because of its ability to attack otherwise healthy individuals after long flights (over three hours). During long plane flights, move around as much as possible, even if it is limited to wiggling your toes and ankles. If you are expecting surgery, quitting smoking may greatly reduce your risk of deep vein thrombosis. Depending on your risk factors, a doctor may put you on blood thinning agents or anti-coagulants (anti-clotting agents) prior to surgery.
