Polycythemia vera and pregnancy: a case report with the use of hydroxyurea in the first trimester.

Polycythemia vera (PV) is rarely associated with pregnancy. A 34-year-old patient treated with hydroxyurea for PV became pregnant and was referred to our clinic. At the patient's request, pregnancy was continued. The patient's hematocrit level remained below 45% without any treatment throughout her pregnancy, and a healthy male infant (without any congenital malformations or complications) was delivered at 37 weeks. This case report suggests that normal pregnancy and delivery is possible in patients with PV.
