Successful urokinase treatment of massive pulmonary embolism in pregnancy.

BACKGROUND

Thrombolytic agents have been used successfully to treat patients with massive pulmonary embolism and cardiorespiratory insufficiency, but experience with these drugs in pregnancy is limited.

CASE

A 20-year-old woman at 21 weeks' gestation was admitted with a massive pulmonary embolism. She was initially given intravenous heparin therapy but because of worsening clinical condition, urokinase was used. After two 12-hour periods of therapy, the urokinase was discontinued and the heparin restarted. She remained on subcutaneous heparin therapy for the remainder of her pregnancy, which was otherwise uncomplicated. She delivered a healthy male infant at term without complications and was discharged on warfarin therapy.

CONCLUSION

Thrombolytic therapy can be life-saving and should be considered in the treatment of hemodynamically significant pulmonary embolism in pregnancy.
