Objective: To evaluate the application of different uterine artery embolization procedures under balloon occlusion of the abdominal aorta in patients with Placenta Accreta Spectrum (PAS) undergoing cesarean section. Materials and Methods: A retrospective analysis was performed on clinical data from 72 patients who underwent uterine artery embolization for hemostasis during cesarean section with PAS. The patients were divided into two groups according to the embolization method used during surgery: group A (n = 43) underwent uterine artery embolization by withdrawing the balloon and inserting a Cobra catheter into the uterine artery for embolization, while group B (n = 29) underwent uterine artery embolization with a Cobra catheter inserted via contralateral puncture of the femoral artery and balloon occlusion. General information, surgical data, and postoperative recovery were compared between the 2 groups. Results: The bleeding and transfusion volumes were lower in group B than in group A and the differences between the 2 groups were statistically significant. There were no significant differences in surgical duration, number of embolized vessels, length of hospital stay, postoperative complications, or menstrual recovery between the 2 groups. Conclusion: For patients with PAS undergoing cesarean section, uterine artery embolization for hemostasis is preferably performed by inserting a Cobra catheter via contralateral puncture of the femoral artery under abdominal aortic balloon occlusion.

Aim: This retrospective study aimed to investigate the value of exome sequencing (ES) in fetuses with isolated first‐trimester increased nuchal translucency (NT) and normal chromosomes. Methods: ES was performed on 103 fetuses with isolated first trimester increased NT and normal chromosomes. The detection rate of monogenic conditions was analyzed. Results: Diagnostic variants were detected in nine cases in which phenotypes and genotypes correlated well, two positive cases were Thanatophoric dysplasia type I, and one case was Kabuki syndrome, which had been detected in previous studies. Eight of the nine cases with diagnostic variants developed additional structural malformations later in pregnancy. Among the nine positive cases, six had a NT thickness between 95th percentile (95th–3.4 mm), and three cases with an increased NT of 3.5 mm or greater. Also, there was no statistical difference in the diagnosis of diagnostic variants in cases with or without a thickened nuchal fold (NF). Conclusions: The diagnostic yield of prenatal ES is low for fetuses with an isolated increased NT. In addition to Noonan syndrome, there are additional genetic syndromes such as Kabuki syndrome and Thanatophoric dysplasia type I that are potentially associated with an increased NT. A cut‐off of greater than the 95th percentile may be useful in case selection for ES. Whether it is clinically meaningful to monitor NF values for fetuses with isolated increased NT and normal chromosomes worth considering. [ABSTRACT FROM AUTHOR]

To compare conservative management and cesarean hysterectomy in patients with placenta increta or percreta. In this multicenter retrospective study, we recorded data on 2219 patients with placenta increta or percreta from 20 tertiary care centers in China from 1 January 2011 to 31 December 2015. Propensity score analysis was used to control for baseline characteristics. We divided patients into conservative management (C) and hysterectomy (H) groups. The primary outcome was operative/postoperative maternal morbidity; secondary outcomes were maternal–neonatal outcomes. In total, 17.9% (398/2219) of patients had placenta increta and percreta; 82.1% (1821/2219) of the patients were in group C. After propensity score matching, 140 pairs of patients from the two groups underwent one-to-one matching. Group C showed less average blood loss within 24 h of surgery (1518 ± 1275 vs. 4309 ± 2550 ml in group H, p<.001). There were more patients with blood loss >1000 ml in group H than in group C (93.6% [131/140] vs. 61.4% [86/140], p<.001). More patients received blood transfusions in group H than in group C (p=.014). There was no significant difference between the groups in terms of bladder injury, postoperative anemia, fever, and disseminated intravascular coagulation. Neonatal outcomes in the two groups were similar. Either conservative management or hysterectomy should be considered after thorough evaluation and detailed discussion of risks and benefits. A balance between bleeding control and fertility can be achieved. [ABSTRACT FROM AUTHOR]
