Introduction: Thrombocytopenia can result from a wide range of conditions with several of them being pregnancy related. Obstetricians manage most cases of pregnancy-associated thrombocytopenia. Thus, a working knowledge of the clinical features and management of thrombocytopenia in pregnant women is important. The objective of the study was to evaluate the causes of thrombocytopenia and its effect on maternal and neonatal outcome in parturient women and also evaluate the obstetric risk factors, complications, and outcome of pregnancies complicated by thrombocytopenia. Materials and Methods: A prospective study of 100 antenatal women with thrombocytopenia who delivered at St John's Medical College Hospital during a one and a half year period. The blood samples of pregnant women in labor room were collected at the time of admission. These women were followed up till they deliver.
Results:The main causes of thrombocytopenia were hypertensive disorders: preeclampsia (15%), Hemolysis, elevated liver enzymes, and low platelets (24%) and eclampsia (4%); idiopathic thrombocytopenic purpura (16%), gestational thrombocytopenia (11%). Women with hypertensive disorders had higher rates of cesarean delivery (65%), intrauterine growth restriction (30%) and preterm deliveries (31%). Hemorrhagic complications are common in rarer causes of thrombocytopenia.
Conclusion:The adverse outcome is specifically attributed to preeclampsia, HELLP syndrome and rare causes. While the perinatal outcome of GT and ITP is basically favorable. Careful surveillance is required for these women in high-risk units for early detection and treatment of possible complications, in order to reduce adverse maternal and neonatal outcomes.
