[Phlebitis of the right upper limb and thromboembolic pulmonary hypertension. Apropos of a case of heart-lung transplantation].

The authors report the case of a 25 year old man with unexplained pulmonary hypertension during his first hospital admission. However, a past medical history suggesting right arm vein thrombosis was obtained. Venography showed signs of thoraco-brachial compression. After heart-lung transplantation, pathological studies of the explanted organs showed changes of thrombo-embolic pulmonary hypertension. A spontaneous right arm venous thrombosis occurred during convalescence. The possibility of post-embolic pulmonary hypertension caused by venous thrombosis of the upper limbs is discussed.
