A comparison of antenatally and intraoperatively diagnosed cases of placenta accreta spectrum

Abstract

Objective: To assess the effect of antenatal diagnosis of placenta accreta spectrum (PAS) on fetomaternal outcomes. Material and Methods: This was a retrospective cohort study conducted from January 2017 to December 2018. Women with PAS diagnosed antenatally were designated as group A and those where diagnosis was suspected during operation and confirmed on histopathology (PAS diagnosed perioperatively) were designated as group B. Outcome in terms of uterine conservation, maternal death, admission of mother to intensive care unit (ICU), perinatal death and neonatal ICU (NICU) admission were recorded. Results: During the study, PAS was confirmed in 96 cases which were included. Out of these, 34 (35.4%) cases were included in group A while 62 (64.6%) were diagnosed intraoperatively (group B). The median number of units of blood transfused was lower in group A compared to group B (4 vs 6, p<0.001). The uterus was conserved more often in group A compared with group B (67.6% vs 43.5%, p=0.024) while admission to ICU occurred significantly more often in group B (26.5% vs 59.7%, p=0.002). Maternal death (p=0.038) and perinatal death (p=0.008) were also significantly higher in group B. More neonates delivered to mothers in group B were admitted to NICU (85.7% vs 24%, p=0.033). Survival analysis showed a statistically significant increase in uterine conservation rate in group A compared with group B (log rank, p=0.04). Conclusion: PAS diagnosed antenatally has better fetomaternal outcome than intraoperative detection of PAS. Diagnosing PAS antenatally is therefore crucial to improve management and achieve a better outcome. (

“…Penetrating PI can also cause secondary injuries during cesarean section or hysterectomy due to placenta invasion to surrounding tissues (ureter, bladder, etc.) [ 14 ]. Prenatal diagnosis and classification of PI have guiding value for perinatal planning, to reduce or avoid the corresponding complications.…”

Placenta accreta spectrum disorders—experience of management in a German tertiary perinatal centre

“…In contrast, placenta increta or percreta is associated with ultrasound signs such as loss of 'clear zone' or bladder wall interruption and evidence of increased vascularity [ 35 , 36 ]. Thus, studies that exclusively consider the latter show higher detection rates in comparison to all investigated cases [ 37 , 38 ]. This is also confirmed in our study cohort with 75% prenatally diagnosed placenta increta and percreta.…”

“…Así, por ejemplo, disminuye la cantidad del sangrado, las unidades de hemoderivados para transfusión, así como los días de hospitalización en el posoperatorio. De esta manera, al igual que la participación multidisciplinaria, la planificación y la anticipación de complicaciones en casos de acretismo placentario se asocia con mejores resultados (18).…”
