Forceps delivery after molar malignancy in a woman with arteriovenous malformation. A case report.

BACKGROUND

An arteriovenous (AV) fistula in the female pelvis is a rare finding. This report describes a successful pregnancy after selective embolization of a postmolar vascular malformation.

CASE: At 5 weeks of pregnancy, a 27-year-old, white female, gravida 3, para 0, was discovered on ultrasound examination to have an AV malformation along with a fetal pole. The patient was asymptomatic and had previously received two courses of chemotherapy for a previous nonmetastasized malignant molar pregnancy. Doppler ultrasonography uncovered a vascular malformation extending from the margin of the fetal pole to the margin of the uterus. The pregnancy ended at 8 weeks with a spontaneous abortion. The patient underwent angiography and embolization of extensive right-sided uterine vessels. She resumed normal menstrual periods six weeks after the embolization and became pregnant. The pregnancy concluded in low forceps vaginal delivery of a healthy, female infant at 34 weeks.

CONCLUSION

Vaginal delivery following postmolar pregnancy and a uterine AV malformation may be considered a viable delivery option.
