  • Application value of lower abdominal aorta compression in hysterectomy for pernicious placenta previa

    Objective To explore the value of lower abdominal aorta compression in emergent hysterectomy during cesarean section because of pernicious placenta previa. Method We retrospectively analyzed the clinical data of four patients who underwent hysterectomy for pernicious placenta previa with the assistance of lower abdominal aorta compression between January 2016 and March 2017 in Sichuan Provincial Hospital for Women and Children. Result The four patients were cured successfully, and the mothers and babies were all well with no pelvic organ damage or complications related to lower abdominal aorta compression. Conclusions Lower abdominal aorta compression in hysterectomy for pernicious placenta previa during cesarean section is a feasible procedure; it can effectively reduce the amount of bleeding, less affect maternal blood circulation, make surgery area clear, and give the operators the chance to do hysterectomy calmly. Lower abdominal aorta compression presents more and more advantages to treat pernicious placenta previa and may be an effective emergency measure to reduce hemorrhage during perioperative period especially under the circumstances of no chance to carry out vascular intervention treatment.

  • The value of ultrasound combined with MRI in the diagnosis of pernicious placenta previa

    ObjectiveTo explore the significance of ultrasound combined with magnetic resonance imaging (MRI) in the diagnosis of pernicious placenta previa (PPP).MethodsA total of 101 patients with suspected PPP admitted to Chengdu Women’s and Children’s Central Hospital from January 2016 to February 2019 were retrospectively analyzed. The surgical results were used as the gold standard, and the diagnostic value of ultrasound, MRI, ultrasound combined with MRI was compared.ResultsSurgery results showed that among the 101 patients with suspected PPP, 79 patients had positive PPP diagnosis and 22 patients had negative PPP diagnosis. There was no significant difference in the diagnostic sensitivity, negative predictive value, or diagnostic coincidence rate of PPP among ultrasound, MRI, and ultrasound combined with MRI (P>0.05). The diagnostic specificity of the series combination of ultrasound and MRI (86.36%) was higher than that of ultrasound (59.10%), MRI (59.10%), and the parallel combination of ultrasound and MRI (31.32%), and the differences were statistically significant (P<0.05). The diagnostic coincidence rates of abnormal placental attachment of MRI (96.20%) and the parallel combination of ultrasound and MRI (96.20%) were higher than that of ultrasound (87.34%) and the series combination of ultrasound and MRI (87.34%) (P<0.05).ConclusionsUltrasound combined with MRI has a high diagnostic value for PPP. If necessary, ultrasound combined with MRI can be considered to improve the diagnostic efficiency.
