Thrombolysis for pulmonary embolism during pregnancy . About four cases.

Pregnancy is correlated with a significant increase in the risk of pulmonary embolism (PE) given the physiological changes in fibrinolysis and mechanical stress induced by the pregnant uterus. Our goal is to demonstrate through four cases of massive bilateral PE occurred during pregnancy, the possibility of thrombolysis in pregnant women. We report the observation of four pregnant patients, between 28 and 38 years old and whose term varies between nine and 36 last menstrual period, hospitalized for serious PE complicated by cardiorespiratory arrest in one case and haemodynamic instability in other cases.
