On Friday, former American Idol contestant Michael Johns suddenly died at age 35, allegedly from a blood clot that formed in his ankle. No official details have been released, but TMZ is reporting that Michael Johns twisted his ankle. Other celebrities who have made relatively recent headlines for suffering from DVT include Real Housewives of Atlanta star, Nene Leakes, and Tennis Star Serena Williams. Other well known figures such as
Richard Nixon, Dan Quayle, Dick Cheney and David Bloom have all suffered a potentially fatal deep venous thrombosis (DVT).
Deep venous thrombosis (DVT) mainly affects the large veins in the lower leg and thigh. The clot can block blood flow and cause swelling and pain. When a clot breaks off and moves through the bloodstream, this is called an embolism. An embolism can get stuck in the brain, lungs, heart, or other area, leading to severe damage.
Blood clots may form when something slows or changes the flow of blood in the veins. Risk factors include:
- Cigarette smoking
- Family history of blood clots
- Fractures in the pelvis or legs
- Giving birth within the last 3 months
- Heart Failure
- Recent surgery (especially hip, knee, or female pelvic surgery)
- Too many blood cells being made by the bone marrow
You’re also more likely to develop DVT if you have any of the following conditions:
- Blood that is more likely to clot (hypercoagulability)
- Taking estrogens or birth control pills.
- Long airplane flights: London’s Heathrow Airport reports one passenger death a month from DVT. One nearby hospital recorded thirty passenger deaths from DVT in the past three years including a 28-year-old man. To reduce the risk of DVT during air travel, passengers are advised to wear compression stockings on flights, frequent moving aroudnt he cabinand pumping the calf muscles, leg elevation and avoidance of sedentary positions for long periods of time without moving.
If you might have a DVT, it is important to see a doctor. Signs of a DVT may be sudden leg pain and swelling. It can be diagnosed by ultrasound imaging. See our other blogs about ultrasound imaging and DVT detection.
