Pregnancy Evolution, Associated Complications and Perinatal Outcome in Patients with Placenta Previa and Placental Abruption

MOJ Womens Health 2017, 4(5): 00096 the umbilical cord briefness, uterine sudden decompression, deficiencies of folic acid, prolonged preterm membranes rupture, polyhydramnios and the former PA in the previous pregnancy [5]. Ananth et al. [6] conducted a meta-analysis recently and assessed the relationship between PA, prolonged rupture of the membranes and gestational hypertension. They found that the risk of PA is strongly associated with chronic high blood pressure, prolonged membranes rupture and specially the history of PA in a previous pregnancy. The former PA in the previous pregnancy seems to relate intimately with the probability of PA in future pregnancies, increasing the incidence of PA between 10 and 15 times [7]. In a cohort study conducted by Kramer et al. [8] on 36.875 births, relationship was found as etiologic determinants of PA to the following factors: severe intrauterine growth restriction, prolonged rupture of the membranes, chorioamnionitis, both gestational and pre-pregnancy hypertension, smoking, advanced maternal age, single mother and male fetal sex. We conducted a retrospective review of assisted patients at our Hospital in the last 10 years and we selected patients with PA whose medical record allowed us to get information about what happened (n: 111), patients with varying degrees of placenta praevia (PP) which also obtain information (n: 84) and comparison was made with the general population (PG) hospital assisted during 1996 (n (: 7.103). Epidemiological comparisons (maternal age, previous gestations), evaluation of associated maternal pathology, characteristics of the current pregnancy, perinatal outcomes and maternal complications also were made. In the case of PA, patients were selected for evaluation with clear description in the surgical record of presence of PA in different percentage, with compatible clinical signs (uterine hyperton basically with not attributable cause) and with the final pathology report which confirmed the diagnosis. In the case of PP, were selected for evaluation patients with Ultrasonographic diagnosis of PP and compatible clinical evolution, mainly attributable to PP: bleeding episodes. Recently, have been informed a case of PA diagnosed trough the suspicion because of a maternal hemoperitoneum [9]. The patients were treated according to the guide of procedures for each pathology, in the Emergency Department of the Hospital from 1.983 [10,11]. With the modifications made to 1.994 [12,13]. The statistical evaluation were used in tests of chi square, difference of proportions and Odds ratio.
