What are the complications of hydatidiform mole?

Answer

Perforation of the uterus during suction curettage sometimes occurs because the uterus is large and boggy. If perforation is noted, the procedure should be completed under laparoscopic guidance.

Hemorrhage is a frequent complication during the evacuation of a molar pregnancy. For this reason, intravenous oxytocin should be started at the initiation of the suctioning. Methergine and/or Hemabate should also be available. Blood for possible transfusion should be readily available.

Malignant trophoblastic disease develops in 20% of molar pregnancies. For this reason, quantitative hCG should be serially monitored as described below (long-term monitoring).

Factors released by the molar tissue could trigger the coagulation cascade. Patients should be monitored for disseminated intravascular coagulopathy (DIC).

Trophoblastic embolism could cause acute respiratory insufficiency.^[27] The greatest risk factor for this complication is a uterus larger than that expected for a gestational age of 16 weeks. The condition may be fatal.
