What is a venous thrombosis ?

Called “a superficial one” when affecting the small veins between the skin and the muscle, and “profound” when affecting a more important vein.

Situated most often of this profound phlebitis within the lower limbs (legs, thighs, the groin). The clog can being detached and then provokes a pulmonary embolism (obstruction of the pulmonary artery). Profound thrombosis needs urgently a consultation.


Which are the factors of risk ?

Obesity, cardiac insufficiency, tobacco (especially when associated to contraceptive drugs), some cancer cases (chest, abdomen, pelvis). Surgical intervention demands a particular surveillance: These factors are favouring the small vascular lesions which are a fertile ground for developing a thrombosis.
Also a pregnancy, a travel with a long plane flight can heighten the risk of getting a thrombosis.

Which are the symptoms of a venous thrombosis  ?

A superficial thrombosis can cause severe pain and a reddening of the zone around, which is lasting (hardening).

Its profound form, sometimes coming with the superficial signs is associated to :

  1. A more widespread pain
  2. An inflammation
  3. A bluish colour of the concerned zone
  4. Awarming of the skin and an expansion of the superficial veins.

Therefore, an urgent consultation is needed.

Which are the treatments needed ?

For giving a diagnosis, the doctor has the choice of different exams: venous Echo-Doppler, veinography (detailed X-Ray of the zone where a clog is esteemed to be).

The treatment is based on the administration of anicoagulants (heparin, VKA).
