Successful treatment of massive pulmonary embolism with recombinant tissue type plasminogen activator (rt-PA) in a pregnant woman with intact gravidity and preterm labour.

We report a patient with massive pulmonary embolism and circulatory shock during pregnancy (31st gestational week) and preterm labour who has been successfully treated with recombinant tissue type plasminogen activator. Thrombolysis was performed using 10 mg.h-1 over 4 h followed by 2 mg.h-1 for 1 h 30 min resulting in complete resolution of cardio-respiratory symptoms. Except for slight bleeding from one puncture site no complications occurred. At 48 h after the end of thrombolytic therapy the patient was delivered spontaneously of a male preterm healthy infant. The relevance of this new thrombolytic agent in the treatment of massive life-threatening pulmonary embolism during pregnancy is discussed.
