Jan. 14, 2009 – The risk of long-term complications from deep phlebitis affects more people than previously thought, researchers at McGill University have found. And conventional treatment with anticoagulants does not prevent these complications called post-thrombotic syndrome.
According to the results of the study143% of the 387 participants who had deep phlebitis experienced post-thrombotic syndrome during the two years of the study. In one third of these patients, moderate or severe symptoms were noted.
The researchers were very surprised to find that almost half of the patients experienced complications that manifested in persistent pain and swelling in the legs and, in more severe cases, the formation of painful ulcers. “The symptoms are identical to those of deep phlebitis, but slower and less constant,” explains Dr.D Susan Kahn, Director of the Thrombosis Clinic at McGill University.
“People with deep phlebitis need long-term follow-up to avoid developing post-thrombotic syndrome,” adds Dr.D Kahn. She also recommends that these people wear medical compression stockings to prevent long-term complications.
Deep phlebitis is the third most common cardiovascular disease in Canada, after heart attack and stroke. It is caused by a blood clot forming in a vein that completely or partially blocks blood flow.
