Objective: The majority of previa-related bleeding is due to an adhesive placenta. The risk factors are already well known. Although antenatal bleeding in women with placenta previa is another problem, the risk factors have not been identified. Our aim is to investigate the risk factors for antenatal bleeding in women with placenta previa. Methods:This was a retrospective study of postpartum women who received an ultrasound diagnosis of placenta previa. Included women were divided into two groups based on whether they had antenatal bleeding or not. Sonographic images were reviewed. Parameters assessed included loss of the retroplacental clear zone, irregularity of uterine-bladder interface, number of lacunar spaces, vasa previa and increased vascularity around placenta. We also assessed the type of placenta previa, placenta location, cervical length at third trimester and obstetric histories. Statistical analyses were performed using a t-test, X 2 test and logistic regression test. Results:Of 109 patients included, 55 (50.5%) experienced antenatal bleeding. There was no significant difference in maternal age between the two groups (P=0.903). Obstetric histories, cervical length at third trimester and sonographic findings were not significantly different. Conclusion:Prediction of antenatal bleeding in placenta previa using obstetrical history and sonographic finding is difficult.

Aim:We evaluated the effectiveness of intraoperative wireless ultrasonography in determining the location of uterine incision during cesarean delivery in patients with placenta previa who have sonographic adherence findings in order to assess intraoperative blood loss and maternal morbidity. Methods: A prospective study using wireless sonography, including 15 patients with previa, was conducted among women with singleton pregnancies who delivered by cesarean section between August 1, 2017, and August 30, 2019. Retrospective study for the control group included 32 patients with placenta previa who underwent cesarean section between January 1, 2016, and July 31, 2017, without wireless sonography. Patients with previa who had adherence findings in prenatal sonography were included in both groups. Logistic regression was used to identify the association between massive intraoperative bleeding loss and use of wireless ultrasound sonography. Results: Intraoperative blood loss was significantly reduced in the study group compared to that in the control group (P = 0.009). The hospital stay was significantly shorter in the study group compared to the control group (5 days vs 6 days, P < 0.001). The use of intraoperative wireless sonography (P = 0.01) had a significant association with massive intraoperative hemorrhage in multivariable analysis. Conclusion: Our study is the first study to apply a wireless ultrasound sonography device in women with placenta previa during cesarean section to examine maternal morbidity. This latest wireless ultrasound sonography device is advantageous for uterine incision guidance in women with placenta previa and improves maternal morbidity by reducing intraoperative hemorrhage.

Placenta previa and maternal hemorrhagic morbidity

Abstract: Placenta previa is an independent risk factor for maternal hemorrhagic morbidity. Some risk factors are modifiable, but many are intrinsic to the clinical scenario.
