[Chronic pulmonary hypertension caused by left axillary vein thrombosis. Report of a clinical case].

Deep venous thrombosis (DVT) of the upper extremity is infrequent, occurring with an incidence estimated at 1-3% of that of DVT of the lower extremity; acute pulmonary embolism following upper extremity DVT is very uncommon; thromboembolic chronic hypertension is quite rare. Therefore a case of chronic thromboembolic pulmonary hypertension due to a non-traumatic ("spontaneous") left axillary vein thrombosis is described: in this case only the double lung transplantation has been shown to be effective in the treatment of advanced cardiopulmonary disorder.
