If I have deep vein thrombosis in my legs, is this condition alone enough to cause death?

Yes if it breaks off. Deep vein thrombosis (DVT) is a clot that has formed in one of the deep veins, typically in the legs. By itself the majority of cases do not cause death when treated properly. The clot however may become bigger or break loose, traveling to the heart and lungs where it becomes a more serious condition with a higher risk of death. Treatment usually is a blood thinner medication and close follow-up.
Not Directly. Fatalities from deep vein thrombosis occur when a blood clot deep in the body breaks off and travels to the heart and lungs and plugs up a blod vessel. It frequently starts in an arm or leg. It can stop yor heart or cause critical illness. The deep vein thrombosis itself can also cause other serious but not fatal complications.
Dvt. The risk of dvt is possible pulmonary embolism which can cause death Treatment with anticoagulation thins the blood to prevent worsening of the dvt.
Don't forget GCS. As dr. Hansen said, do not forget graduated compression stockings (gcs). They should have 30-40 mm hg compression and be knee high. Ted hose aren't adequate. Gcs need to be worn for at least 2 years to decrease the risk of post-thrombotic syndrome by 50%.

Can wrapping your legs around each other more than once cause varicose veins / deep vein thrombosis?

Unlikely. Very unlikely especially for short periods of time but for long periods and sitting like in airplanes then yes it can increase risk of dvt. Read more...
No. Despite what you might have heard many times before, crossing your legs doesn't cause varicose veins. It also probably isn't possible to cross your legs twice for long enough to give you a deep vein thrombosis, unless you were dehydrated and had an underlying inherited increased tendency to clot too easily in the first place. Your legs would likely fall asleep first. Read more...
No. Simply crossing your legs or wrapping your legs will not cause varicose veins or deep venous thrombosis. Varicose veins are typically gentically acquired and not related to leg positioning. Deep venous thrombosis can be caused by many things, including prolonged stationary state for too many hours without movement, but simply crossing the legs would not cause a DVT. Read more...
Wrapping legs. Wrapping legs has not been shown to increase the likelihood of causing varicose veins or acute deep vein thrombosis. You could get DVT if you crossed your legs "Indian style" for many many hours without getting up and walking. There is no hard data regarding this observation. Read more...
