Thrombosis long-term sequelae

By long-term sequelae we mean those symptoms or signs that persist for months or years after an illness.

One year after a DVT, one in two patients have permanent discomfort in the leg, either pain, cramping, tingling, itching, heaviness or swelling, or a combination of these. This is known as post-thrombotic syndrome and is the most common complication following thrombosis.

It is a discomfort that can significantly alter the patient’s life. The ankles swell, the skin hardens, changes colour, cramps, pruritus (tingling) and paraesthesia (burning or prickling sensation) may occur.

If this continues, ulcers may appear which are usually not painful, but they can easily become infected and ooze.

Scientific studies have shown that ulcers are more common in men, people with varicose veins, people who have already suffered from thrombosis and diabetics.

To prevent such complications, doctors recommend that patients walk frequently, do not sit cross-legged, and whenever possible, slightly raise their leg when seated. In standing, a strong compression stocking must be worn.
