[Preterm delivery by cesarean section in patient with polycythemia vera]. / Przedwczesne ukonczenie ciazy cieciem cesarskim u pacjentki z czerwienica prawdziwa.

Polycythemia vera is a myeloproliferative disease most commonly diagnosed in male 60-70 years old patients. It is associated with a higher risk of thrombosis and bleeding. It is very rarely diagnosed in young patients, and thus only few cases of pregnant women have been reported in the literature. These reports show that polycythemia vera may have a detrimental effect on outcome of the pregnancy (PIH, spontaneous miscarriages, preterm delivery, and stillbirth). We report a 33-year-old woman with polycythemia vera who underwent caesarean delivery in 34 weeks gestation. This case demonstrates fully successful result of our intensive perinatal care.
