Essential thrombocythemia and pregnancy: a report of six normal pregnancies in five untreated patients

To report our experience with essential thrombocythemia complicating pregnancy. METHODS: Over a 5-year period, we studied 21 women of reproductive age affected by essential thrombocythemia. Diagnoses were based on previously published Polycythemia Vera Study Group criteria. RESULTS: Five of our 21 patients became pregnant (total six pregnancies). All pregnancies were carried to term, with uncomplicated deliveries of normally formed infants. No thrombotic or hemorrhagic complications were encountered. CONCLUSION: Normal pregnancy and delivery is readily possible in patients with essential thrombocythemia.
