Pregnancy-Related Hysterectomy for Peripartum Hemorrhage: A Literature Narrative Review of the Diagnosis, Management, and Techniques

Predictive model for postpartum hemorrhage requiring hysterectomy in a minority ethnic region

BACKGROUND

Postpartum hemorrhage (PPH) is a leading cause of maternal mortality, and hysterectomy is an important intervention for managing intractable PPH. Accurately predicting the need for hysterectomy and taking proactive emergency measures is crucial for reducing mortality rates.

AIM

To develop a risk prediction model for PPH requiring hysterectomy in the ethnic minority regions of Qiandongnan, China, to help guide clinical decision-making.

METHODS

The study included 23490 patients, with 1050 having experienced PPH and 74 who underwent hysterectomies. The independent risk factors closely associated with the necessity for hysterectomy were analyzed to construct a risk prediction model, and its predictive efficacy was subsequently evaluated.

RESULTS

The proportion of hysterectomies among the included patients was 0.32% (74/23490), representing 7.05% (74/1050) of PPH cases. The number of deliveries, history of cesarean section, placenta previa, uterine atony, and placenta accreta were identified in this population as independent risk factors for requiring a hysterectomy. Receiver operating characteristic curve analysis of the prediction model showed an area under the curve of 0.953 (95% confidence interval: 0.928-0.978) with a sensitivity of 90.50% and a specificity of 90.70%.

CONCLUSION

The model demonstrates excellent predictive power and is effective in guiding clinical decisions regarding PPH in the ethnic minority regions of Qiandongnan, China.

Peripartum Subtotal Hysterectomy in Multifetal Gestation

Peripartum hysterectomy (PH) is usually undertaken in cases of life-threatening obstetric haemorrhage to prevent the death of the mother. Obstetric haemorrhage, a leading indication for PH, is a major cause of maternal deaths globally, particularly in regions with limited access to advanced medical care. The cause of the per vaginal bleeding was due to the patient in labour with a cervical stitch, and immediate action was taken in the form of a lower segment caesarean section. After the patient's abdominal drain is noticed with fresh blood collection, an emergency obstetric hysterectomy is done.

Reflections on peripartum hysterectomy: A 10-year retrospective observational study in Northeast China

OBJECTIVE

To explore the change trends in incidence and leading factors to peripartum hysterectomy (PH) at a regional tertiary medical center in northeast China.

METHODS

This was a retrospective observational study of all PH cases conducted at Shengjing Hospital between January 1, 2012 and December 31, 2021. Information on maternal characteristics of pregnancy and delivery, indications of PH, inventions before hysterectomy, complications, and maternal and neonatal outcomes obtained from the Shengjing Hospital Information System were analyzed.

RESULTS

Among a total of 157 553 deliveries, there were 127 cases of PH (overall PH incidence: 0.85/1000 deliveries); 120 patients (94.49%) underwent hysterectomy after cesarean section, and seven (5.51%) underwent vaginal delivery (P < 0.001). Abnormal placentation was the leading indication for PH (101, 79.53%), including placenta previa (PP) with placenta accreta spectrum (PAS) (93, 73.23%), PP alone (5, 3.94%), and PAS alone (3, 2.36%). Among the patients who underwent PH with abnormal placentation, 92.08% had at least one cesarean section (P < 0.001) and 20.19% had bladder injury (P = 0.044). All maternal deaths (n = 2) occurred in referral patients, and the maternal mortality rate was 1.57/100 hysterectomies.

CONCLUSION

Abnormal placentation was the primary indication for PH. For such patients, adequate assessment of their condition and complete communication are strongly recommended. The identification of high-risk groups for postpartum hemorrhage, timely and effective rescue, and referral are equally important for avoiding PH.

Procedural techniques to control postpartum hemorrhage

Postpartum hemorrhage can occur unexpectedly and with high dynamics. The mother's life often depends on quick action and good communication within an interdisciplinary team. Knowledge of each other's therapeutic options plays a major role. Treatment procedures include obstetric, surgical, and radiologic techniques. In addition to availability and experience with the techniques, two important aspects must be considered in the selection process: the type of delivery and the cause of the hemorrhage. In particular, the distinction between pregnancies with or without disturbed placentation from the placenta accreta spectrum is crucial. From these two points of view, we discuss here different uterus-preserving and uterus-removing techniques. We describe in detail the advantages and disadvantages of each procedure. Because most therapeutic options are based on small case series and uncontrolled studies, local circumstances and physician experience are critical in setting internal standards.

Prevalence and Factors Associated with Peripartum Hysterectomy among Iranian Pregnant Women: A Retrospective Study

BACKGROUND

Peripartum hysterectomy (PPH) is one of the effective treatment modalities which is increasingly performed to save the life of pregnant women with uncontrollable severe postpartum hemorrhage. The aim of this study was to assess the prevalence and factors associated with PPH among Iranian pregnant women.

METHODS

In a retrospective study, 33 pregnant women with PPH referred to Imam Khomeini Hospital in Sari, Mazandaran province, northern Iran were enrolled. Data were collected using census sampling from March 2017 to 2020. Patients' sociodemographic and clinical characteristics were collected. Fisher's exact test, Kruskal-Wallis, and Mann-Whitney tests were used to evaluate the study variables.

RESULTS

The prevalence of PPH among Iranian pregnant women was 2.81 per 1000 deliveries. The mean length of stay in the hospital and intensive care unit (ICU) was 6.15 (SD=2.91) and 3.17 (SD=1.50) days, respectively. Of the participants, 90.9% had a cesarean section, 51.6% had emergency PPH, 88.2% had emergency PPH in 24 hours after delivery, 9.1% had an induction, and 60.6% had PPH due to placental abnormalities. The mean duration of PPH procedure was 2.51 (SD=1.14) hours. The most common post-operative complication in participants was fever. Participants with older gestational age had more elective PPH (P=0.029). The length of ICU stay was more in patients with total PPH procedure compared to the supracervical (P<0.017). The induction rate was higher in emergency PPH after vaginal delivery compared to cesarean section (P=0.005).

CONCLUSION

This study showed a high prevalence of PPH among pregnant women. Also, there was a significant relationship between the PPH and length of ICU stay, especially after supracervical hysterectomy. The results of this study can help obstetrician-gynecologist to provide a better intervention for managing patients with postpartum hemorrhage requiring PPH.
