The Dangers of Deep Vein Thrombosis
Copyright 2005 Anne Wolski
A deep vein thrombosis is a blood clot developing in a deep
vein, usually in the leg. They also can occur in other parts of
the body. Blood clots in the veins in the thigh are usually more
serious than blood clots that happen in veins in your lower leg.
A DVT causes pain, and possible complications if it reaches the
lungs. If a clot in a vein breaks off and travels through your
bloodstream, it can lodge in your lung. This is called a
pulmonary embolism which is a very serious condition that can
cause death.
DVTs are known to occur in about 1 out of 1000 people in the
general population from all causes. DVTs are more common in
obese people and those aged over 40. Causes include
long-distance air travel and long journeys by car, train or
coach, because of prolonged immobility.
Symptoms of Deep vein thrombosis include: Swelling of the leg;
Pain or tenderness in the leg-the pain is usually in one leg and
may only be present when standing or walking ; Feeling of
increased warmth in the area of the leg that is swollen or that
hurts ; Red or discolored skin.
The main goals in treating deep vein thrombosis are to: Stop the
clot from getting bigger; Prevent the clot from breaking off in
your vein and moving to your lungs ; Reduce your chance of
having another blood clot.
Exercising the legs once an hour can reduce risk. Take regular
breaks if driving, or walk up and down the coach, train or plane
aisle.
Lower leg muscles can be exercised while sitting by pulling the
toes towards the knees then relaxing, or by pressing the balls
of the feet down while raising the heels.
Other preventative measures include: Avoid sleeping pills. These
cause immobility, increasing the risk of DVT; Wear loose
clothing; Keep legs uncrossed.; Keep hydrated by drinking.;
Avoid alcohol to prevent dehydration. ; Wear graduated
compression stockings or socks - particularly important for
travelers with other DVT risk factors. Compression stockings are
worn on the legs from the arch of the foot to just above or
below the knee. These stockings are tight at the ankle and
become looser as they go up the leg. This causes a gentle
compression (or pressure) up your leg. They have some side
effects: They can be uncomfortable when worn all day They can be
hot They may be difficult to put on, especially for older adults
and overweight people.
Some doctors recommend aspirin because of its blood thinning
effects. This is unsuitable for children and can have side
effects, so seek professional advice.
