Objective: to evaluate pregnancy outcomes in pregnant women with placenta previa (PP) and to correlate these with the different types of PP.Methods: review of the clinical files of 67 gestations complicated with PP who delivered at our department between October 2003 and July 2009. Data extracted included demographic characteristics, risk factors for PP, number of vaginal bleeding episodes, need for and duration of hospitalization, gestational age at delivery, need for an urgent intervention, maternal morbidity (post-partum hemoglobin < 8.0 g/dl, need for blood transfusion, surgical intervention for post-partum haemorrhage) and mortality.Results: a total of 36 women (53.7%) had a complete PP, 8 (11.9%) had a parcial type, and 23 (34.3%) had a marginal PP. At least one risk factor was present in 57 women (85%), and 33 (58%) had two or more risk factors. Thirty-nine (58%) women were hospitalized due to vaginal bleeding and 29 (43.3%) required an urgent/emergent cesarean delivery. Sixteen women (23.8%) had significant morbidity. Except for gestational age at delivery (which was lower for complete PP) and duration of hospital stay (which was higher for complete PP), no statistically significant difference in outcomes was seen with the different types of PP. Conclusions: PP is associated with a significant risk of maternal morbidity, irrespective of its type.
