title: [Development of pulmonary embolism].
abstract: The authors have made a study of the fate of 118 patients with pulmonary embolism. The mortality (21.8%) is related not only to the embolus itself (especially to the recurrent types) but also to the condition of the affected area. Recurrence is common (34%), serious (9 deaths out of 25), and early (during the first three months.). No treatment or inadequate treatment are the main causes. Treatment works effectively on the pulmonary circulation, which becomes reestablished in the majority of cases, but it carries the risk of a high incidence of haemorrhage (29%) which is severe (2 deaths and 10 tranfusions of more than one litre of blood). In the long term, the prognosis is linked to the developments in the lower limbs, in which there is a progressive failure of venous drainage (46 cases out of 57), even in cases in which there was no local sign of phlebitis at the time of the original embolus.
