Hospital Stockings Cut Problems From Leg Clot
But Expert Says Use Them Only If Other Methods Fail

Aug. 16, 2004 -- They're ugly and maybe even
uncomfortable. But those "hospital stockings" could prevent
complications after a blood clot in the leg, new research
However, one expert advises wearing them
only after trying other lifestyle changes.
DVT, or deep vein thrombosis, is a common
problem for anyone who stays off their feet for an extended period of time.
People who are hospitalized or immobile because of an injury often get them.
Even air travelers who sit in cramped seats for hours are at risk; then it's
called "economy class syndrome."
Typically, a person with a clot is put on a
blood thinner to prevent new clots from forming. But blood thinners don't
dissolve the existing clots.
One of every three to four DVT patients
develops a complication from the clots - lower leg swelling, skin
discoloration, numbness, chronic leg pain, hardening of the skin, or leg
Wearing compression stockings every day
dramatically cuts these complications for up to two years, reports Paolo
Prandoni, MD, PhD, with the University Hospital of Padua in Italy. His paper
appears in the Annals of Internal Medicine this month.
In his study, 180 patients hospitalized
with DVT were given blood thinning medication. Before they were discharged,
they were randomly assigned to wear or not wear elastic compression stockings
daily for two years.
The compression stocking group had better
results than the non-stocking group:
- After six months, 40% of the non-stocking group
developed complications, compared with 21% of the stocking group.
- After one year, 47% of the non-stocking patients had
problems, compared with 22% of the stocking group.
- After two years, 49% of the non-stocking patients had
complications, while only 25% of the stocking patients did.
Overall, the stockings did their job,
cutting DVT problems almost in half, reports Prandoni.
Are They Really Necessary?
The compression stockings admittedly
"are hot in the summer, relatively expensive, difficult for many patients
to put on in the morning, and cosmetically unappealing to many," writes
Jeffrey S. Ginsberg, MD, of McMaster University in Hamilton, Ontario, in an
Sometimes, a simple lifestyle change --
frequently elevating the affected leg, not sitting or standing for long periods
of time, using pain medications -- help control the symptoms, he explains.
Patients with swelling in their legs may want to try support hose. If things
get worse or if a skin ulcer develops, the full-strength compression stockings
However, if DVT symptoms subside, there's
no need to wear them, writes Ginsberg.
