“…The histological grade was determined by hematoxylin and eosin (HE) staining. The specimens were classified into low-(grade 1 and 2) and high-grade (grade 3) groups based on the International Federation of Gynecology and Obstetrics (FIGO) grading system (23). For the Ki-67 index, a murine Ki-67 monoclonal antibody (M3G4; Celnovte, Rockville, MD, USA) was used to stain tissue fragments, and then the positive cells were counted at 400× magnification in 10 hotspots (areas with more positive cells).…”

Background: Noninvasive identification of the histological features of endometrioid adenocarcinoma is necessary. This study aimed to investigate whether amide proton transfer-weighted imaging (APTWI) and multimodel (monoexponential, biexponential, and stretched exponential) diffusion-weighted imaging (DWI) could predict the histological grade of endometrial adenocarcinoma (EA). In addition, we analyzed the correlation between each parameter and the Ki-67 index.Methods: A total of 90 EA patients who received pelvic magnetic resonance imaging (MRI) were enrolled.The magnetization transfer ratio asymmetry [MTRasym (3.5 ppm)], apparent diffusion coefficient (ADC), diffusion coefficient (D), pseudo-diffusion coefficient (D*), perfusion fraction (f), distributed diffusion coefficient (DDC), and water molecular diffusion heterogeneity index (α) were measured and compared.Correlation coefficients between each parameter and histological grade and the Ki-67 index were calculated.Statistical methods included the independent samples t test, Spearman's correlation, and logistic regression. Results: MTRasym (3.5 ppm) [(3.72%±0.31%) vs. (3.27%±0.48%)], f [(3.15%±0.36%) vs. (2.69%±0.83%)], and α [(0.89±0.05) vs. (0.81±0.09)] were higher and ADC [(0.82±0.08) vs. (0.89±0.10) ×10 −3 mm 2 /s], D [(0.67±0.09) vs. (0.81±0.11) ×10 −3 mm 2 /s], and DDC [(1.04±0.09) vs.(1.13±0.13) ×10 −3 mm 2 /s] were lower in high-grade EA than in low-grade EA (P<0.05). MTRasym (3.5 ppm) and D were independent predictors for the histological grade of EA. The combination of MTRasym (3.5 ppm) and D were better able to identify high-and low-grade EA than was each parameter. MTRasym (3.5 ppm) and α were moderately and weakly positively correlated, respectively, with histological grade and the r=0.514, r=0.395, and r=0.367; P<0.05). D was moderately negatively correlated with histological grade and the Ki-67 index (r=-0.540 and r=-0.529; P<0.05). DDC was weakly and moderately negatively correlated with histological grade and the Ki-67 index, respectively (r=-0.473 and r=-0.515; P<0.05). ADC was weakly negatively correlated with histological grade and the Ki-67 index (r=-0.417 and r=-0.427; P<0.05). f was weakly positively correlated with histological grade and the Ki-67 index (r=0.294 and r=0.355; P<0.05).

The aim of this study was to evaluate the efficacy and safety of prophylactic intraoperative bilateral uterine or internal iliac artery embolization in planned cesarean for pernicious placenta previa in the third trimester of pregnancy. The patients with pernicious placenta previa were retrospectively included from January 2011 to May 2018, being divided into embolization group and control group. Intraoperative uterine artery embolization (UAE) or internal iliac artery embolization (IIAE) was undertaken to stop intrapartum and postpartum hemorrhage in embolization group. There were no significant differences on age, pregnancy times, gestational age, neonatal weight, neonatal asphyxia, prenatal bleeding, placental implantation, and mortality between embolization group and control group (P > .05). The amount of intraoperative and postoperative bleeding in embolization group was significantly greater than that in control group (P < .05). However, the hysterectomy rate in the embolization group was significantly lower than that in the control group (P < .05). Two (6.25%, 2/32) cases had undergone the second time embolotherapy after 8 hours of cesarean surgery because of severe vaginal bleeding. One case (3.13%, 1/32) died of diffuse intravascular coagulation because of hemorrhagic shock in embolization group. Transient and self-remitted lumbosacral pain was present in 28 (95%, 28/32) patients and no other severe interventional complications were reported in embolization group. All babies in 2 groups were healthy at half to 5 years’ follow-up. The prophylactic intraoperative embolization of bilateral UAE or IIAE may be an effective strategy to treat intractable peripartum hemorrhage and preserve the fertility in patients with pernicious placenta previa.

Comparison of selective and non‐selective internal iliac artery embolization for abnormal placentation with major postpartum hemorrhage

Abstract: Non‐selective internal iliac artery embolization for abnormal placentation and postpartum hemorrhage resulted in ischemic skin necrosis whereas selective embolization did not; unilateral embolization was ineffective.
