[Venous thrombosis. Experience in treatment, problems and perspectives]

Venous thromboembolic disease is a recurring reason for death, it is often well-known but sometimes misunderstood. The right treatment for this pathology should not follow one approach only, but several strategies with respect to the seriousness and extension of the several clinical pictures. In particular the pharmacological therapy tries to find the balance between risks and benefits. It is well-known that a weak treatment may cause an increase in the risk of the pathology extension or of recurrence; on the other hand, a therapy exceeding the well known ranges exposes to important hemorrhagic risk.

This work presents the personal seven years' experience in patients affected by limb venous thrombosis, in some cases combined with pulmonary embolism. For all patients the pathology seriousness has been assessed by echoduplex scanner and angio-CT, and routine serum electrolite and enzymes analysis and blood counts have been carried out. Different therapies have been investigated, their evolution over the years (on the basis of international and personal experience) and the follow-ups.

The foudamental implications of this experience are: the more remarkable use of vena cava filters do not improve clinical findings' follow-up. On the contrary, it can cause the extension of pathology; heparin therapy must start early and the therapeutic range must be reached as soon as possible. Any delay, together with immobilization, can cause the extension of the pathology; diagnosis research cannot stop at the acuity moment but it should study also the etiopathogenetic picture. This affects the future therapeutic strategy in the follow-up; fibrinolitic therapy, once recommended for extended femoral-iliac thrombosis, should be used for serious levels of the same pathology and only for patients with low haemorrhage risk, or for patients affected by periodic pulmonary thromboembolism which may compromise haemodynamic system.
