“…This issue was also the focus of the work of a Nationwide Cohort Study in The Netherlands [9] that identified a prevalence of PPH of 7.4% in women with PE compared to a prevalence of 4.2% in women without PE, even after adjusting for confounders. These findings, in addition to the results obtained by Naruse and colleagues [1], increase the awareness of the risks of hemorrhagic events in women with PE in clinical practice.…”

“…However, many cases of GA at less than 34 GA weeks are managed with an expectant approach due to prematurity. The findings from Naruse and colleagues [1] suggest an additional risk for abruption of the placenta in expectant patients with PE admitted at <34 weeks GA (OR, 3.77; 95% CI, 3.13-4.53) and contribute to clinical practice by adding an important element to be considered in expectant patients.…”

“…Abruption of the placenta is an obstetric emergency that is usually catastrophic and requires prompt diagnosis and immediate intervention, usually by emergency cesarean section, to save the fetus and reduce the risk of bleeding complications in the mother. The results from Naruse et al [1] highlight that this serious condition has occurred after hospital admission in expectant patients with early onset PE at a GA less than 34 weeks.…”

“…In a very interesting paper, Naruse et al [1] analyzed a retrospective cohort from a Japanese database, identifying a higher incidence of placental abruption in women with severe preeclampsia (PE) when admitted at less than 34 weeks gestational age (GA). Abruption of the placenta is an obstetric emergency that is usually catastrophic and requires prompt diagnosis and immediate intervention, usually by emergency cesarean section, to save the fetus and reduce the risk of bleeding complications in the mother.…”

Aim: To investigate whether placental abruption without fetal distress could be assessed by apparent diffusion coefficient (ADC) values in magnetic resonance imaging (MRI). Methods: We conducted a retrospective case-control study at a single center. ADC values at the lesions of placental abruption in the abruption group (n = 8) were compared to those in the control group (n = 32). In the abruption group, ADC values at the sites of abruption were also compared to those at the nonabruption sites within the same placenta. Results: The ADC values in the placental area above the abruption site in the abruption group showed lower values than those in the control group when the slice containing the umbilical cord insertion site was set as the reference, and those values were compared in each corresponding slice. Compared with average ADC values, those above the abruption site in the abruption group were also significantly lower than those in the control group (p < 0.001). Furthermore, ADC values at the area above abruption were lower than those at the nonabruption area of all planes in the abruption group. Conclusions: ADC values at the lesions above the placental abruption site were reduced compared to those in the normal placenta and those in the nonabruption area. Thus, it would be helpful to understand the pathophysiology of placental abruption in expectant management, although further investigations would be needed.
