Background: The prevalence of thrombocytopenia in most studies ranges from 7 to 10% of all
pregnant females. Although pregnancy is associated with physiological changes that may affect
platelet count, several pathological conditions can cause thrombocytopenia which have a significant
impact on both the mother and her baby.
Objective: The aim of this study was to determine the prevalence of thrombocytopenia in pregnant
women attending an out-patient clinic in Al-Yarmouk Teaching hospital in Baghdad.
Material and Methods: A cross sectional study conducted at Al-Yarmouk Teaching Hospital from
1st October 2016 to 1st July 2017. Five hundred sixty pregnant women randomly selected as the study
group and another 100 non-pregnant women as the control group were enrolled in this study. A
complete blood count and blood film were done for both the selected groups.
Results: Thrombocytopenia was found in 7.1% of the cases. The most common cause of
thrombocytopenia was gestational thrombocytopenia seen in 19(47.5%) patients and PE & HELLP
syndrome 9 (22.5%) patients. Most of our cases were asymptomatic and only one case developed
heavy vaginal bleeding while there were 2 cases who had platelets below 50,000 considered as severe
thrombocytopenia without significant bleeding.
Conclusion: Thrombocytopenia is not a rare condition in pregnancy. Accurate etiological diagnosis is
essential for effective management. Most of the cases are mild, self-limiting and rarely cause with
complications
