Deep Venous Thrombosis

Deep Venous Thrombosis (DVT) or “economy class syndrome” is a term used to describe a partial or near full clot of a major blood vessel. It occurs most often as a result of prolonged immobility in a limb, leading to stasis of circulation, giving it opportunity to coagulate or clot.

The danger of a DVT is its potential to dislodge. It can then travel to the smaller pulmonary vessels close to the lungs, creating a pulmonary embolism (blockage of lung vessels). Blood is no longer able to pass through the lungs and oxygen/carbon dioxide exchange is compromised. Immediate sharp stabbing pain is felt in the chest. If emergency medical intervention is delayed, it can be potentially fatal. This can occur over a space of days, and at times, even a week.

Although the majority of DVTs occur in the leg, it has been seen clinically in the upper limbs. Nevertheless, DVT does occur more in the leg, of which 95% is in the thigh (femoral vein) while 5% in the calf (saphenous vein).

The risk factors of developing DVT include smoking, obesity (overweight), sedentary lifestyle, prolonged immobility, elderly, past history of DVT, and long surgical procedures.

Once a DVT is found, it can be treated effectively through anti-coagulant medication and physiotherapy exercises. If this fails, then surgery would be indicated.

Like most conditions, prevention is always better than treatment, and involves:

  1. Reducing possible risk factors
  2. Keeping mobile (eg: walk every thirty minutes on long flights)
  3. Wearing compressive stockings to assist circulation
