Fertility rate and subsequent pregnancy outcomes after conservative surgical techniques in postpartum hemorrhage: 15 years of literature

Clinical outcomes and future fertility after uterine artery embolization for postpartum and post-abortion hemorrhage

BACKGROUND

Postpartum hemorrhage (PPH) and post-abortion hemorrhage (PAH) are life-threatening conditions.

PURPOSE

To evaluate the efficacy and safety of uterine arterial embolization (UAE) for PPH and PAH and to investigate future fertility after UAE.

MATERIAL AND METHODS

This study included 57 consecutive patients (mean age = 34 years) who underwent UAE for PPH (n = 46) and PAH (n = 11) at our institution between January 2011 and December 2022. Technical success, non-visualization of the peripheral portion of bilateral uterine arteries on angiography, and clinical success, complete hemostasis after UAE, were assessed. UAE-associated complications and factors related to clinical success were analyzed. Pregnancy outcomes after UAE and complications during subsequent pregnancy were investigated in 16 patients who desired fertility and were followed up for >1 year.

RESULTS

The technical and clinical success rates were 100% and 84.2%, respectively. Sepsis (n = 1) and uterine empyema (n = 1) were observed as severe complications. Placental disorder, bleeding within 24 h after delivery or abortion, ≥1.5 shock index, ≥6 units of transfusion erythrocytes, and ≥8 obstetrical disseminated intravascular coagulation score were significantly associated with unfavorable clinical outcomes. In total, 16 pregnancies were observed in 12 patients after UAE, three of which were miscarriages and 13 were successful live births. During pregnancy, uterine rupture (n = 1) and accreta (n = 1) were observed.

CONCLUSION

UAE is an effective treatment for PPH and PAH. Although UAE could preserve future fertility, careful attention should be paid to perinatal management for unusual complications.

Efficacy and Safety Analyses of Recombinant Factor VIIa in Severe Post-Partum Hemorrhage

Background: Despite a range of available treatments, it is still sometimes challenging to treat patients with severe post-partum hemorrhage (sPPH). Objective: This study evaluated the efficacy and safety of recombinant activated factor VIIa (rFVIIa) in sPPH management. Methods: An open-label, multi-center, randomized controlled trial (RCT; NCT00370877) and four observational studies (OS; OS-1 (NCT04723979), OS-2, OS-3, and OS-4) were analyzed regarding efficacy (need for subsequent invasive procedures, including uterine compression sutures, uterine or iliac artery ligations, arterial embolization, or hysterectomy) and safety (incidence of thromboembolic events (TE) and maternal mortality) of rFVIIa for sPPH. The RCT, and OS-1 and OS-2, included a control group of women who did not receive rFVIIa (with propensity score-matching used in OS-1 and OS-2), whereas OS-3 and OS-4 provided descriptive data for rFVIIa-exposed women only. Results: A total of 446 women exposed to rFVIIa and 1717 non-exposed controls were included. In the RCT, fewer rFVIIa-exposed women (50% [21/42]) had an invasive procedure versus non-exposed women (91% [38/42]; odds ratio: 0.11; 95% confidence interval: 0.03-0.35). In OS-1, more rFVIIa-exposed women (58% [22/38]) had an invasive procedure versus non-exposed women (35% [13.3/38]; odds ratio: 2.46; 95% confidence interval: 1.06-5.99). In OS-2, 17% (3/18) of rFVIIa-exposed women and 32% (5.6/17.8) of non-exposed women had an invasive procedure (odds ratio: 0.33; 95% confidence interval: 0.03-1.75). Across all included women, TEs occurred in 1.5% (0.2% arterial and 1.2% venous) of rFVIIa-exposed women and 1.6% (0.2% arterial and 1.4% venous) of non-exposed women with available data. Conclusions: The positive treatment effect of rFVIIa on the RCT was not confirmed in the OS. However, the safety analysis did not show any increased incidence of TEs with rFVIIa treatment.

Fertility after Transcatheter Arterial Embolization for Obstetric Hemorrhage: An Urban Health Care System Observational Study

OBJECTIVE

 This study aimed to investigate pregnancy rate, pregnancy outcomes, and resumption of menses after transcatheter arterial embolization (TAE) for obstetric hemorrhage (OH).

STUDY DESIGN

 Sixty-seven patients who underwent TAE for OH from 2006 to 2020 within an urban, multihospital health care system were identified retrospectively. Selected patients were interviewed by phone to complete a survey with a primary outcome of self-reported pregnancy in those seeking pregnancy. Secondary outcomes included pregnancy outcomes and resumption of menses. Univariate testing of association of pregnancy and miscarriage rate with embolic agent was performed using Fisher's exact test.

RESULTS

 Thirty-three of 50 patients (66%) meeting the inclusion criteria completed the survey on fertility, a median of 47 (range, 13-123) months after TAE for OH. Of the 13 patients who attempted pregnancy, there was a pregnancy rate of 77% and miscarriage rate of 38%. Those who delivered live newborns conceived spontaneously, carried to term, and delivered a healthy newborn via cesarean section at a weight appropriate for gestational age. Thirty (91%) patients resumed menstruation, and the majority with unchanged frequency. Most patients underwent bilateral uterine artery embolization with radial artery access (54%). The most common embolic agents used were gelfoam only (30%) and glue only (24%). There was no statistically significant association between embolic agent and pregnancy or miscarriage rate.

CONCLUSION

 Spontaneous pregnancy with live birth and resumption of menses can occur in a majority of patients after TAE for OH.

KEY POINTS

· Most patients who attempted pregnancy after TAE for OH achieved pregnancy.. · Most patients who became pregnant conceived spontaneously and delivered healthy newborns at term.. · Most patients resumed menstruation after TAE for OH.. · There was no significant association between type of embolic and pregnancy or miscarriage rate..

Subsequent pregnancy in women who have undergone bilateral uterine artery ligation during cesarean section: A case series

Bilateral uterine artery ligation (BUAL) serves as an effective surgical devascularization procedure in obstetric emergencies. However, concerns regarding the impact of uterine devascularization have evoked dispute. Here, the fetal growth index and obstetrical outcomes during the subsequent pregnancy of women who had undergone BUAL during cesarean section are reported. The case series of women who underwent BUAL during cesarean section and had another delivery later at the Xiamen Women and Children's Hospital between 2011 and 2020 is described. Pregnancies that did not continue beyond 20 weeks of gestation were excluded. Cases were identified from neonatal and obstetric databases and the clinical data of all cases were extracted. A total of 12 cases were identified retrospectively. Fetal biometric parameters of subsequent pregnancies in all cases including biparietal diameter, head circumference, abdominal circumference, and femur length are presented graphically across the different gestational ages and were all within the range of the 3rd-97th percentile. No maternal or neonatal morbidity was observed. BUAL did not appear to compromise a woman's subsequent obstetric outcomes. As a safe and simple surgical technique, it is safe to recommend BUAL in clinical practice.

Pregnancy rate and outcomes after uterine artery embolization for women: a systematic review and meta-analysis with trial sequential analysis

Objective

The assessment of the relative impacts of uterine artery embolization (UAE) treatment for female patients is a critical field that informs clinical decisions, yet there is a noticeable scarcity of high-quality, long-term comparative studies. This meta-analysis aimed to focus on the pregnancy rate and outcomes in female patients following UAE and to conduct subgroup analyses based on different patient populations or various control treatments.

Methods

A systematic literature search was conducted on 2 August 2023 through the Web of Science, PubMed, Embase, and the Cochrane Library of Clinical Trials for all potential studies. Relative risks (RRs) with 95% confidence intervals (CIs) were applied to compare pregnancy rates and outcomes between the UAE group and the control group. Heterogeneity was evaluated statistically by using the chi-square-based Cochran's Q test and Higgins I2 statistics, and 95% prediction interval (PI). Software R 4.3.1 and Stata 12.0 were used for meta-analysis. The trial sequential analysis (TSA) was performed with TSA v0.9.5.10 Beta software.

Results

A total of 15 eligible studies (11 cohort studies, 3 randomized controlled trials, and 1 non-randomized clinical trial) were included in this meta-analysis. The overall results revealed that UAE significantly decreased postoperative pregnancy rate [RR (95% CI): 0.721 (0.531-0.979), 95% PI: 0.248-2.097] and was associated with an increased risk of postoperative PPH [RR (95% CI): 3.182 (1.319-7.675), 95% PI: 0.474-22.089]. Analysis grouped by population indicated that UAE decreased the risk of preterm delivery [RR (95% CI): 0.326 (0.128-0.831), p = 0.019] and cesarean section [RR (95% CI): 0.693 (0.481-0.999), p = 0.050] and increased the risk of placenta previa [RR (95% CI): 8.739 (1.580-48.341), p = 0.013] in patients with UFs, CSP, and PPH, respectively. When compared with myomectomy, HIFU, and non-use of UAE, UAE treatment was associated with the reduced risks of preterm delivery [RR (95% CI): 0.296 (0.106-0.826)] and cesarean section [(95% CI): 0.693 (0.481-0.999), p = 0.050] and increased placenta previa risk [RR (95% CI): 10.682 (6.859-16.636)], respectively.

Conclusion

UAE treatment was associated with a lower postoperative pregnancy rate and increased risk of PPH. Subgroup analysis suggested that UAE was shown to decrease the risk of preterm delivery and cesarean section and increase placenta previa risk.Systematic review registration:https://www.crd.york.ac.uk/prospero/, Identifier CRD42023448257.

Hysteroscopy after conservative surgical treatment of severe postpartum hemorrhage due to uterine atony: A systematic literature review

OBJECTIVE

To assess the prevalence of intrauterine anomalies, primarily intrauterine adhesions (IUAd), after conservative surgical treatment of severe postpartum hemorrhage with uterine atony (SPPH-UA) and determine patient eligibility for hysteroscopy.

METHODS

PubMed and the Cochrane Library were searched by combining keywords "postpartum hemorrhage", "uterine atony", and "hysteroscopy" to perform a literature review. Articles in French and English with more than five cases of hysteroscopy following SPPH-UA were selected. All cases that had hysteroscopy after conservative surgical treatment of SPPH-UA were collected. A blinded statistical analysis revealed IUAd risk factors.

RESULTS

In all, 83% of patients agreed to hysteroscopy and 38% of 71 cases had an IUAd. Age was not a risk factor (P = 0.950). Other factors included multiparity (odds ratio [OR] 1.93, P = 0.039), cesarean delivery (OR 3.58, P = 0.584) and postpartum infection (OR 3.33, P = 0.04). Risk was at 57% after uterine padding with multiple transfixing square stitches (Cho-technique) (P = 0.001), 6% after non-transfixing uterine folding brace suture (B-Lynch technique) when used alone, 29% after uterine artery embolization and after internal iliac artery ligation (OR 0.98, P = 0.645); uterine vascular ligation (OR 0.69, P = 0.253) and more than two procedures (OR 0.69, P = 2.53). Disparity between authors was observed (P = 0.015) and concerned only the surgical techniques used.

CONCLUSION

A classification is proposed for deciding post-SPPH hysteroscopy. Further studies are required to determine appropriateness.

Obstetrical and Fertility Outcomes Following Transcatheter Pelvic Arterial Embolization for Postpartum Hemorrhage: A Cohort Follow-Up Study

Objectives: Management of severe postpartum hemorrhage (PPH) includes transcatheter pelvic arterial embolization (TAE). Data regarding subsequent fertility and obstetrical outcomes is limited, as most fertility outcomes derive from TAE in uterine fibroma. The purpose of our study was to evaluate the long-term outcomes of patients undergoing TAE, particularly concerning subsequent fertility and following pregnancies. Material and methods: We included 28 patients who underwent TAE for PPH at our institution between 2009 and 2018 in a retrospective cohort study. Data were assessed by reviewing patients’ charts and by contacting the patients. Results: Ten patients had prophylactic balloon occlusion before cesarean section because of anticipated PPH, with planned hysterectomy by placenta increta/percreta. All these patients were excluded from the analysis regarding fertility. 16 (73%) patients reported having regular menstruation after TAE. In total, 11 women had no desire for subsequent pregnancy. Seven of the remaining 11 patients (63.6%) had a total of 13 spontaneous pregnancies, nine of these resulted in miscarriages. Four patients delivered a live baby (36.4%). Two of these (50%) had recurrent PPH and treatment was conservative. Of the patients with infertility (n = 4, 36.4%), two (18.1%) underwent assisted infertility treatment without success. Conclusion: Our study suggests that the fertility of patients undergoing TAE due to PPH is limited. In women who conceive, the risk for first trimester miscarriage as well as recurrent PPH seems to be increased. If this is a consequence of the underlying cause of PPH or the TAE remains unknown. Larger follow-up cohorts are needed. In the meantime, patients who desire pregnancy after TAE should be counseled accordingly.

Postpartum haemorrhage and risk of long-term hypertension and cardiovascular disease: an English population-based longitudinal study using linked primary and secondary care databases

OBJECTIVE

To investigate the long-term risk of developing hypertension and cardiovascular disease (CVD) among those women who suffered a postpartum haemorrhage (PPH) compared with those women who did not.

DESIGN

Population-based longitudinal open cohort study.

SETTING

English primary care (The Health Improvement Network (THIN)) and secondary care (Hospital Episode Statistics (HES)) databases.

POPULATION

Women exposed to PPH during the study period matched for age and date of delivery, and unexposed.

METHODS

We conducted an open cohort study using linked primary care THIN and HES Databases, from 1 January 1997 to 31 January 2018. A total of 42 327 women were included: 14 109 of them exposed to PPH during the study period and 28 218 matched for age and date of delivery, and unexposed to PPH. HRs for cardiovascular outcomes among women who had and did not have PPH were estimated after controlling for covariates using multivariate Cox regression models.

OUTCOME MEASURES

Risk of hypertensive disease, ischaemic heart disease, heart failure, stroke or transient ischaemic attack.

RESULTS

During a median follow-up of over 4 years, there was no significant difference in the risk of hypertensive disease after adjustment for covariates (adjusted HR (aHR): 1.03 (95% CI: 0.87 to 1.22); p=0.71). We also did not observe a statistically significant difference in the risk of composite CVD (ischaemic heart disease, heart failure, stroke or transient ischaemic attack) between the exposed and the unexposed cohort (aHR: 0.86 (95% CI: 0.52 to 1.43; p=0.57).

CONCLUSION

Over a median follow-up of 4 years, we did not observe an association between PPH and hypertension or CVD.

Subsequent pregnancy outcome after uterine compression suture placement for postpartum hemorrhage

OBJECTIVE

To evaluate the subsequent obstetrical outcome in women who received a uterine compression suture.

METHODS

This is a retrospective cohort study of women who received a uterine compression suture for postpartum hemorrhage (PPH) between January 2009 and December 2018 and had a subsequent pregnancy at a tertiary care hospital in India. Women who had PPH but did not receive uterine compression sutures and had a subsequent pregnancy were taken as controls.

RESULTS

Sixty-two women had a subsequent pregnancy after uterine compression suture and were included in this study. There were no significant differences in the subsequent pregnancy outcome between the study and control groups. However, women with a history of uterine compression suture were found to have a higher incidence of dense omental adhesions (15% versus 2.8%; P < 0.001), more intrapartum blood loss (740.5 ± 491.8 ml versus 638.8 ± 194 ml; P = 0.02), and were more likely to need repeat uterine compression suture (6.7% versus 0%; P = 0.004).

CONCLUSION

Women who received uterine compression sutures had similar obstetrical outcomes in their subsequent pregnancy compared with those who did not receive a suture for PPH management. However, they had a higher risk of dense omental adhesions, repeat uterine compression suture application, and intrapartum blood loss.

The Emergent Pelvic Artery Embolization in the Management of Postpartum Hemorrhage: A Systematic Review and Meta-analysis

Importance

Postpartum hemorrhage (PPH) is an emergent obstetric complication and the leading cause of maternal mortality. Pelvic arterial embolization (PAE) is an effective treatment for intractable PPH. However, a unique protocol has not been accepted in obstetrical practice.

Objective

To evaluate its efficiency, safety, complications, and outcomes, we conducted a systematic review and meta-analysis of PAE for PPH in the literature.

Evidence Acquisition

The Medline, the database of abstract of reviews, the index to allied health literature, and the Chinese database Sino-Med were searched on March 31, 2020, for studies on PAE for PPH. The data for PAE indication, agents, arteries, success rate, complications, and outcomes were extracted and syncretized for meta-analysis.

Results

From 1075 identified articles, 113 abstracts or full articles were retrieved and 43 studies were finally identified as meeting the including criteria. The results demonstrated that the indications for PAE were as follows: uterine atony, placental abnormality, delivery tract injury, disseminated intravascular coagulation, arteriovenous malformation, and vaginal hematoma. The embolization agents mostly in order were gelatin sponge particles, polyvinyl alcohol particles, Gelfoam, N-butyl cyanoacrylate, microcoil, and glue; for arteries, they were mostly uterine artery and internal iliac artery. The clinical success rate was 90.5%, whereas the technical success rate was 99.3%. The most common complications of PAE were postembolization syndrome and menstrual abnormality.

Conclusions and Relevance

The emergent PAE is a safe and effective method with high success rate in life-threatening PPH management. Gelatin sponge granules measuring 500 to 1000 μm in diameter have safe results. Pelvic arterial embolization may affect the recovery of menses and increase PPH in the subsequent pregnancy, but there was no noted correlation with fetal growth restriction.

Removable retropubic uterine compression suture for controlling postpartum hemorrhage

OBJECTIVE

To minimize the adverse events of uterine compression suture in controlling postpartum hemorrhage (PPH) and to search for a prophylactic approach to potential PPH.

METHODS

A retrospective analysis was performed in 39 women with removable retropubic uterine compression suture (RRUCS) to stop PPH due to uterine atony during cesarean section (CS). The procedure was to suspend and compress the uterus to the retropubic abdominal wall using an absorbable suture.

RESULTS

The technique was sufficient to stanch bleeding immediately in 36 patients (92.31%, 36/39). No morbidity or abnormalities occurred in women who underwent RRUCS. Subsequent pregnancies occurred in 10 cases, but the others lacked the desire for future pregnancy.

CONCLUSION

RRUCS is a simple, safe, and effective technique in controlling atonic PPH; it is also used as a prophylactic application in patients with potential PPH after CS.

Efficacy of Intra-Uterine Tamponade Balloon in Post-Partum Hemorrhage after Cesarean Delivery: An Impact Study

Invasive therapies (surgery or radiological embolization) are used to control severe post-partum hemorrhage. The intra-uterine tamponade balloon is a potential alternative, well documented after vaginal delivery. However, available data on its use after cesarean delivery remain scarce. This study assessed the efficacy of the intra-uterine tamponade balloon during post-partum hemorrhage in a cesarean delivery setting. Using a retrospective impact design, post-partum hemorrhage-related outcomes before (“pre-balloon” period) versus after implementation of intra-uterine tamponade balloon (“post-balloon” period) were compared. All women with post-partum hemorrhage requiring potent uterotonic treatment with prostaglandins after cesarean delivery over a 9-year period were eligible. The primary outcome was the rate of invasive procedure (conservative surgery, radiological embolization and/or hysterectomy). p < 0.05 was considered statistically significant. A total of 279 patients were included (140 vs. 139). Most baseline characteristics were comparable between the two studied periods. The success rate of the intra-uterine tamponade balloon was 82%, and no related complications occurred. Rates of invasive procedures and transfusion were significantly reduced (28.6% vs. 11.5%, p < 0.001 and 44.3% vs. 28.1%, p = 0.006 respectively) during the “post-balloon” period, and length of hospital stay was shorter (p < 0.001). Implementation of intra-uterine tamponade balloon during post-partum hemorrhage after cesarean delivery appears to be safe and effective, with a decrease in both invasive procedures and transfusion rates.

Recurrence of post-partum hemorrhage in women with a history of uterine artery embolization

AIM

To evaluate pregnancy outcome and complications in subsequent pregnancies after severe post-partum hemorrhage (PPH) between women with and without a history of uterine artery embolization (UAE).

METHODS

Women who had a history of severe PPH, and delivered newborns at ≥22 gestational weeks in subsequent pregnancies were enrolled. Severe PPH was defined as blood loss volume of more than 2000 mL.

RESULTS

The blood loss volume (median 1581 mL) in women with UAE (n = 14) was significantly more than that in women without UAE (median 1021 mL, n = 32, P < 0.01), and the recurrence rate of severe PPH in women with UAE (n = 5, 35.7%) was significantly higher than that in women without UAE (n = 3, 9.4%, P < 0.05). There were no significant differences in frequencies of premature delivery, hypertensive disorders of pregnancy, fetal growth restriction, or placenta previa/low lying placenta. Of 14 women with UAE, 7 (50.0%) had abnormally invasive placenta, whereas of 32 women without UAE, none had abnormally invasive placenta.

CONCLUSION

Subsequent pregnancies after UAE for severe PPH had high risks for recurrence of severe PPH.

Menstrual and reproductive outcomes after use of balloon tamponade for severe postpartum hemorrhage

BACKGROUND

The use of intrauterine balloon tamponade to manage postpartum hemorrhage is increasing. However, there is lack of studies on the menstrual and reproductive outcomes after such treatment. The purpose of this study is to explore the menstrual and reproductive outcomes for patients who had been managed by intrauterine balloon tamponade for severe postpartum hemorrhage in her index pregnancy.

METHODS

All patients who had delivered in United Christian Hospital from January 2011 to June 2016 with severe postpartum hemorrhage (PPH) (blood loss> = 1 L) were identified by the labour ward delivery registry and a comprehensive obstetric database. Patients who had intrauterine balloon tamponade inserted were compared with those managed solely by uterotonic agents as controls. Patients who had hysterectomy or additional procedures performed, such as compression sutures or uterine artery embolization were excluded from both groups. A questionnaire on menses, fertility and reproductive outcomes was mailed to both groups of patients. Those that had not replied within 4 weeks would receive a telephone survey.

RESULTS

A total of 39 patients in the balloon tamponade group and 161 patients in the control group were recruited, which represented 87.0% of all eligible patients within the study period. The median follow up period was 45 months. All patients in the balloon tamponade group had return of menses after delivery. The majority of the patients (87.2%) in the balloon tamponade group had normal menstrual patterns in the 12 months after the index delivery as well as in the most recent 12 months. After excluding the patients with contraception, the subsequent pregnancy rate was 42.9% (9/21) in the balloon tamponade group compared to 45.9% (28/61) in the control group (p = 0.81). Among the 9 subsequent pregnancies in the balloon tamponade group, there were two miscarriages, one scar pregnancy, one induced abortion, while the remaining five were normal pregnancies with full term deliveries without intrauterine growth restriction. The majority of patients replied that they were satisfied with using Bakri balloon for PPH management in their index pregnancy.

CONCLUSIONS

Intrauterine balloon tamponade for the management of severe PPH appeared to pose little adverse effects on subsequent menstrual and reproductive function.

Cesarean Scar Ectopic Pregnancy: Current Management Strategies

Importance

Cesarean scar ectopic pregnancy (CSEP) has a high rate of morbidity with nonspecific signs and symptoms making identification difficult. The criterion-standard treatment of CSEP has been subject to debate.

Objective

This review defines CSEP, discusses pathogenesis and diagnosis, and compares treatment options and outcomes.

Evidence Acquisition

A literature review was performed utilizing the term cesarean scar ectopic pregnancy and subsequently selecting only meta-analyses and systematic reviews. Only articles published in English were included. Relevant articles within the reviews were analyzed as necessary.

Results

Five basic pathways have been identified in treatment of CSEP: expectant management, medical therapy, surgical intervention, uterine artery embolization, or a combination approach. Expectant management has the highest probability of morbid outcomes, including hemorrhage, uterine rupture, and preterm delivery. Medical management often requires further treatment with additional medication or surgery. Different surgical methods have been explored including uterine artery embolization; dilation and curettage; surgical removal via vaginal, laparoscopic, or laparotomic approach; and hysterectomy. Each method has various levels of success and depends on surgeon skill and patient presentation.

Conclusions

Recent research supports any method that removes the pregnancy and scar to reduce morbidity and promote future fertility. Laparoscopic and transvaginal approaches are options for CSEP treatment, although continued research is required to identify the optimal approach.

Relevance

As cesarean delivery numbers rise, a subsequent increase in CSEPs can be anticipated. The ability to accurately diagnose and treat this morbid condition is vital to the practice of any specialist in general obstetrics and gynecology.

Effects of prophylactic uterine artery embolization on second-trimester induced abortions in patients with placenta previa

OBJECTIVE

To evaluate the effects of prophylactic uterine artery embolization (UAE) on second-trimester induced abortions in patients with placenta previa.

METHODS

The present study was a retrospective review of second-trimester induced abortions in the presence of placenta previa that conducted between January 1, 2008, and October 31, 2017, at a university hospital in Hangzhou, China. Pregnancy outcomes including intraoperative blood loss, transfusion, dilatation and evacuation, hysterotomy delivery, and hysterectomy were compared between patients with and without prophylactic UAE.

RESULTS

There were 54 patients included in the study. In patients with partial placenta previa (n=15), the volume of intraoperative blood loss and the frequency of dilatation and evacuation were not significantly different between the UAE and non-UAE groups (P>0.05). No patient had a transfusion, hysterotomy delivery, or hysterectomy. Among patients with complete placenta previa (n=39), the volumes of intraoperative blood loss (P=0.014) and transfusion (P=0.046) were significantly lower in the UAE group compared with the non-UAE group. The rates of dilatation and evacuation, and hysterotomy delivery did not differ between the groups (P>0.05), but were numerically higher in the non-UAE group. No patient was treated with hysterectomy.

CONCLUSION

Prophylactic UAE before a second-trimester induced abortion had significant advantages in women with complete placenta previa, but it did not improve the pregnancy outcome in patients with partial placenta previa.

Delayed surgical and non-surgical treatment of placental remnants: no difference was found in the clinical efficacy and long-term pregnancy outcomes

Purpose

In a tertiary hospital, patients facing delayed treatment with placental remnants were common. The aim of this study was to assess the clinical efficacy and long-term pregnancy outcomes of the delayed surgical/non-surgical treatment for placental remnants.

Patients and methods

The records of referral patients with placental remnants after second/third-trimester delivery/termination of pregnancy were retrospectively analyzed. A long-term follow-up was made by phone to inquire about the future pregnancy outcomes. The measurements of clinical efficacy included the postpartum intervals for Doppler ultrasound to become normal and for menstrual cycle to return to normal. Conception rate, interval for future pregnancy and obstetric outcomes were used to assess future pregnancies.

Results

A total of 65 patients, who were clinically diagnosed with placental remnants after termination of pregnancy at the second or third trimester from 2000 to 2016, were included in this study. Delayed surgical treatments employed at a median interval (MI) of 2.7 months after termination of pregnancy had a similar interval for ultrasound (P=0.353) and menstrual cycle (P=0.751) to return to normal compared with non-surgical treatments. For non-lactating patients who accepted expectant treatments, the postpartum interval for ultrasound to return to normal was significantly longer than that for menstrual cycle to become normal (MI=3.6, 1.5 months, respectively, P=0.000). For all of the patients successfully treated, the conception rate (P=1.00), the interval for a second pregnancy (P=0.771), ongoing-pregnancy/live birth rate (P=0.419) and the recurrence rate of placenta accrete (P=1.00) there was no significant difference between non-surgical and surgical treatments. Assisted selective uterine artery embolization at an MI of 23 days after the termination of pregnancy had a longer interval for ultrasound to become normal than single expectant treatment (P=0.017). For all patients after expectant treatments, 94.1% of patients conceived after an MI of 12.5 months with the ongoing-pregnancy/live birth rate of 66.7% and a 33.3% recurrence rate of placenta accreta.

Conclusion

According to our experience, delayed surgeries at a postpartum interval of 2.7 months might have similar clinical efficacy and long-term pregnancy outcomes with expectant treatment in treating placental remnants.

Recent Update of Embolization of Postpartum Hemorrhage

Postpartum hemorrhage (PPH) is a life-threatening condition and remains a leading cause of maternal mortality. Transcatheter arterial embolization (TAE) is an effective therapeutic strategy for PPH with the advantages of fast speed, repeatability, and the possibility of fertility preservation. We reviewed the vascular anatomy relevant to PPH, the practical details of TAE emphasizing the timing of embolization, and various clinical conditions of PPH according to a recent literature review.

Pelvic Artery Embolization for Treatment of Postpartum Hemorrhage

Postpartum hemorrhage (PPH) is the leading cause of maternal perinatal morbidity and mortality worldwide. Defined as greater than 500 mL blood loss after vaginal delivery, and greater than 1,000 mL blood loss after cesarean delivery, PPH has many causes, including uterine atony, lower genital tract lacerations, coagulopathy, and placental anomalies. Correction of coagulopathy and identification of the cause of bleeding are mainstays of treatment. Medical therapies such as uterotonics, balloon tamponade, pelvic artery embolization, and uterine-sparing surgical options are available. Hysterectomy is performed when conservative therapies fail. Pelvic artery embolization is safe and effective, and is the first-line therapy for medically refractory PPH. A thorough knowledge of pelvic arterial anatomy is critical. Recognition of variant anatomy can prevent therapeutic failure. Pelvic embolization is minimally invasive, has a low complication rate, spares the uterus, and preserves fertility.

Work load and management in the delivery room: changing the direction of healthcare policy

Nurse staffing, increased workload and unstable nursing unit environments are linked to negative patient outcomes including falls and medication errors on medical/surgical units. Considering this evidence, the aim of our study was to overview midwives' workload and work setting. We created a questionnaire and performed an online survey. We obtained information about the type and level of hospital, workload, the use of standardised procedures, reporting of sentinel and 'near-miss' events. We reported a severe understaffing in midwives' work settings and important underuse of standard protocols according to the international guidelines, especially in the South of Italy. Based on our results, we strongly suggest a change of direction of healthcare policy, oriented to increase the number of employed midwives, in order to let them fulfil their duties according to the international guidelines (especially one-to-one care). On the other hand, we encourage the adoption of standardised protocols in each work setting.

Early pregnancy serum neopterin concentrations predict spontaneous preterm birth in asymptomatic pregnant women

OBJECTIVE

To investigate if early pregnancy serum neopterin concentrations (EPSN) could predict spontaneous preterm birth (SPB).

METHODS

EPSN was measured in 92 sera collected from 46 pregnant women with birth at term and 40 sera from 20 pregnant women with preterm birth. Two sera were collected for each case: in the first and early second trimester.

RESULTS

EPSN concentrations correlate with gestational age (ρ=0.275, P=0.001), a correlation which was present in both groups: term and preterm birth. EPSN were higher in pregnancies with SPB compared with normal pregnancies (6.27±1.03 vs. 6.04±0.15, P=0.039). Patients with SPB showed a considerable increase of EPSN in the second trimester compared with patients with birth at term (7.30±1.53 vs. 6.16±0.23, P=0.043). A sharper increase was found in the group with SPB before 32 weeks of pregnancy (wp) (9.83±4.36 vs. 6.16±0.23, P=0.016). Pregnant women with an early second trimester serum neopterin value of above 8 nmol/L are associated with a risk of SPB before 32 wp (odds ratio=14.4, P=0.01) and of SPB before 34 wp (odds ratio=3.6, P=0.05), respectively.

CONCLUSIONS

EPSN increases with the gestational age and predicts SPB in asymptomatic pregnant women.

Prevention of primary caesarean delivery: comprehensive management of dystocia in nulliparous patients at term

PURPOSE

Dystocia is the leading indication for primary caesarean sections. Our aim is to compare two approaches in the management of dystocia in labor in nulliparous women with a singleton fetus in cephalic presentation at term in spontaneous or induced labor.

METHODS

Prospective cohort study. Four hundred and nineteen consecutive patients were divided into two groups: the standard management group (SM), in acceleration of labor was commenced at the "action line" in the case of arrested or protracted labor, and the comprehensive management group (CM) in which arrested or protracted labor was considered as a warning sign promoting further diagnostic assessment prior to considering intervention.

RESULTS

Caesarean sections rate was 22.2 % in the SM group (216 patients) and 10.3 % in the CM group (203 patients) (p = 0.001). The rate of oxytocin use decreased from 33.3 % in SM group to 13.8 % in the CM group (p < 0.0005). The rate of amniotomy decreased from 41.7 % in the SM group to 7.4 % in the CM group (p < 0.0005). The percentage of newborns with 5-min Apgar score <7 and/or umbilical cord arterial pH ≤ 7.00 decreased from 2.3 % in SM cohort to 0.5 % in CM cohort (p = ns). The average length of labor did not differ between the two groups of patients (264 vs 277 min; p = ns).

CONCLUSION

Comprehensive management of dystocia enabled us to achieve a reduction in iatrogenic interventions in labor while maintaining good neonatal outcomes.

Uterine artery embolization, not cesarean section, as an option for termination of pregnancy in placenta previa

OBJECTIVE

To summarize our experiences in the treatment of labor induction in placenta previa using uterine artery embolization.

CASE REPORT

We retrospectively analyzed the clinical data of seven patients with placenta previa who underwent antepartum uterine artery embolization before vaginal delivery. After antepartum embolization, five patients with placenta previa had successful vaginal deliveries and two cases of placenta previa with accreta underwent emergency hysterectomy. Some complications were reported in this experience. The follow-up study showed that most patients resumed their normal menstruation and some of them were able to conceive.

CONCLUSION

For the management of placenta previa, uterine artery embolization is a minimally invasive technique that helps to avoid cesarean section. The impact on menstruation and fertility is yet to be seen.

An Update on Maternal Hydration Strategies for Amniotic Fluid Improvement in Isolated Oligohydramnios and Normohydramnios: Evidence from a Systematic Review of Literature and Meta-Analysis

OBJECTIVE

Several trials aimed at evaluating the efficacy of maternal hydration (MH) in increasing amniotic-fluid-volume (AFV) in pregnancies with isolated oligohydramnios or normohydramnos have been conducted. Unfortunately, no evidences support this intervention in routine-clinical-practice. The aim of this systematic-literature-review and meta-analysis was to collect all data regarding proposed strategies and their efficacy in relation to each clinical condition for which MH-therapy was performed with the aim of increasing amniotic-fluid (AF) and improving perinatal outcomes.

MATERIALS AND METHODS

A systematic literature search was conducted in electronic-database MEDLINE, EMBASE, ScienceDirect and the Cochrane-Library in the time interval between 1991 and 2014. Following the identification of eligible trials, we estimated the methodological quality of each study (using QADAS-2) and clustered patients according to the following outcome measures: route of administration (oral versus intravenous versus combined), total daily dose of fluids administered (<2000 versus >2000), duration of hydration therapy: (1 day, >1 day but <1 week, >1 week), type of fluid administered (isotonic versus hypotonic versus combination).

RESULTS

In isolated-oligohydramnios (IO), maternal oral hydration is more effective than intravenous hydration and hypotonic solutions superior to isotonic solutions. The improvement in AFV appears to be time-dependent rather than daily-dose dependent. Regarding normohydramnios pregnancies, all strategies seem equivalent though the administration of hypotonic-fluid appears to have a slightly greater effect than isotonic-fluid. Regarding perinatal outcomes, data is fragmentary and heterogeneous and does not allow us to define the real clinical utility of MH.

CONCLUSIONS

Available data suggests that MH may be a safe, well-tolerated and useful strategy to improve AFV especially in cases of IO. In view of the numerous obstetric situations in which a reduced AFV may pose a threat, particularly to the fetus, the possibility of increasing AFV with a simple and inexpensive practice like MH-therapy may have potential clinical applications. Considering the various strategies of maternal hydration implemented in the treatment of IO, better results were observed when treatment was based on a combination of intravenous (for a period of 1 day) and oral (for a period of at least 14 days) hypotonic fluids (≥2000ml).

The Effect of Gum Chewing, Early Oral Hydration, and Early Mobilization on Intestinal Motility After Cesarean Birth

AIM

The aim of the study was to investigate the effect of gum chewing, early oral hydration, and early mobilization after cesarean birth on intestinal sounds, passing gas, and intestinal evacuation.

DESIGN

Randomized controlled study.

SETTING

This study was conducted at the Obstetrics Service of the one Obstetrics and Child Diseases Hospital.

PARTICIPANTS

A total of 240 females divided into 8 groups of 30 subjects each were included within the scope of the sample.

METHODS

The women who underwent cesarean birth were divided into eight groups by using 2(3) factorial test levels, depending on the use of three different methods of gum chewing, early oral hydration, and early mobilization. No intervention was applied to the women in the control group. For the other seven groups, the intestinal sounds were checked every 30 minutes with a stethoscope over the abdomen and the first time of passing gas and the first evacuation time were recorded by asking the mother. The data were evaluated with numbers, mean, and percentage calculations, Student's t test, one-way variance analysis, correlation, and Tukey HSD test.

RESULTS

The intestinal sounds were heard earlier, gas was passed earlier, and bowel movements were earlier in the first group that received all interventions compared to the other groups (p < .05). The patient could not be discharged before 48 hours had passed after the cesarean birth according to the hospital protocol and the time of discharge was therefore not affected by interventions.

LINKING EVIDENCE TO ACTION

All of the three different interventions, such as gum chewing, early oral hydration, and early mobilization after cesarean birth, increase intestinal motility. The interventions are recommended during postoperative routine care to shorten hospital stay and prevent postoperative ileus.

Outcome of pregnancies after pelvic artery embolization for postpartum hemorrhage: retrospective cohort study

OBJECTIVE

The effects of pelvic artery embolization (PAE) for postpartum hemorrhage (PPH) on subsequent pregnancies have been explored in small case series and one case-control study by mailed questionnaire with uncomplicated pregnancies as controls. We conducted a single-center retrospective cohort study using women with PPH without PAE for comparison.

STUDY DESIGN

From a cohort of 103 women undergoing PAE for primary PPH between January 1999 and December 2012 (exposed) and 189 pregnancies with PPH not requiring PAE between January 2008 and December 2012 (unexposed), we queried the electronic medical records for readmissions to labor and delivery in subsequent years. Outcomes of subsequent pregnancies continuing past 20 weeks were obtained by chart review.

RESULTS

Repeat pregnancies were documented in 17 of 103 exposed women (16.5%) and 18 of 189 unexposed women (9.5%). At delivery complicated by PPH, the groups did not differ in demographics, gestational age, units of blood transfused, or PPH cause. At the time of subsequent deliveries, there was a greater interdelivery interval in women exposed to PAE than those unexposed (1710 ± 938 days vs 904 ± 358 days; P = .002), and the 2 groups were similar in terms of gestational age and birthweight. However, there was a significantly higher rate of placenta accreta in exposed than unexposed women (23.5 % vs 0%; P = .04), with 3 of 17 sustaining total abdominal hysterectomy and 1 requiring repeat PAE for severe PPH.

CONCLUSION

Pregnancies following PAE for PPH were more likely than those not receiving PAE for treatment to be complicated by placenta accreta. Pregnancies following PAE should be followed up for imaging evidence of placenta accreta.

Use of Monsel solution to treat obstetrical hemorrhage: a review and comparison to other topical hemostatic agents

Peripartum hemorrhage accounts for 8% of maternal deaths in the United States, and nearly 27% worldwide. A growing need exists for tactics to spare morbidity given a rise of abnormal placentation that contributes to excessive blood loss at the time of delivery. Approaches such as compression sutures, balloon tamponade, and pelvic artery embolization are not without side effects and potential implications for future fertility. The use of topical hemostatic agents has become widespread in gynecologic and obstetric surgery despite a paucity of distinct studies in the field, and may allow providers to increasingly avoid cesarean hysterectomy. A variety of topical hemostatic agents exist along a wide cost continuum, each characterized by specific efficacy, advantages, drawbacks, and often gaps in long-term data to support safety and impact on future fertility. Herein, we comprehensively review these agents and illustrate a nontraditional use of Monsel solution applied directly to the placental bed in a case of focal placenta accreta. This ultimately contributed to successful uterine preservation with no known adverse sequelae. Monsel solution may have a role in establishing hemostasis in the setting of abnormal placentation, and may be a particularly attractive alternative in resource-poor nations.

Carbetocin versus intra-umbilical oxytocin in the management of retained placenta: a randomized clinical study

AIM

This study aimed to compare the hemodynamic profile and efficacy of carbetocin versus intra-umbilical oxytocin in the management of retained placenta following vaginal delivery.

MATERIAL AND METHODS

In this randomized clinical study, women with retained placenta for more than 30 min were assigned to receive either an i.v. bolus of 100-µg carbetocin (n = 38) or an intra-umbilical vein injection of 50 IU oxytocin in 30 mL saline (n = 40). The main parameters evaluated were the success rate for expulsion of the placenta and the effects of these drugs on maternal blood pressure.

RESULTS

The success rate in the carbetocin group was 86.84% compared to 77.5% in the intra-umbilical oxytocin group. Notably, 57.7% of the participants had prior induction of labor or augmentation during labor. There were no significant differences between the two groups regarding the estimated blood loss, drop of hemoglobin within the first 48 h, additional uterotonic injection or the need for manual removal of the placenta. Systolic blood pressure was significantly lower in the intra-umbilical oxytocin group at 30 and 60 min after injection (P = 0.008, 0.026, respectively). Nonetheless, diastolic blood pressure was significantly lower in the intra-umbilical oxytocin group than in the carbetocin group at 30 min (P = 0.036).

CONCLUSION

A single i.v. bolus of carbetocin and umbilical vein injection of 50 IU oxytocin are similarly effective in reducing the need for manual removal of the placenta. Carbetocin seems to have an acceptable hemodynamic safety profile and can be used as an alternative choice to the conventional oxytocic agents in the management of retained placenta.

How I treat postpartum hemorrhage

Worldwide, ∼800 women die every day from preventable causes related to pregnancy or childbirth. The single most common cause is severe bleeding, which can kill a healthy woman within hours if care is substandard or delayed. Improved antenatal practices have led to the early identification of at-risk women and modern technology and new techniques have enabled effective management strategies so that now, in the western world, most of the morbidity and mortality arises from those cases which occur unexpectedly and could not have been predicted. Prompt and effective management and multidisciplinary involvement is paramount to save the lives of these women. We use a case report to illustrate and discuss the main elements of management of this condition.

Update on best available options in obstetrics anaesthesia: perinatal outcomes, side effects and maternal satisfaction. Fifteen years systematic literature review

PURPOSE

In modern obstetrics, different pharmacological and non-pharmacological options allow to obtain pain relief during labour, one of the most important goals in women satisfaction about medical care. The aim of this review is to compare all the analgesia administration schemes in terms of effectiveness in pain relief, length of labour, mode of delivery, side effects and neonatal outcomes.

METHODS

A systematic literature search was conducted in electronic databases in the interval time between January 1999 and March 2013. Key search terms included: “labour analgesia”, “epidural anaesthesia during labour” (excluding anaesthesia for Caesarean section), “epidural analgesia and labour outcome” and “intra-thecal analgesia”.

RESULTS

10,331 patients were analysed: 5,578 patients underwent Epidural-Analgesia, 259 patients spinal analgesia, 2,724 combined spinal epidural analgesia, 322 continuous epidural infusion (CEI), 168 intermittent epidural bolus, 684 patient-controlled infusion epidural analgesia and 152 intra-venous patient-controlled epidural analgesia. We also considered 341 women who underwent patient-controlled infusion epidural analgesia in association with CEI and 103 patients who underwent patient-controlled infusion epidural analgesia in association with automatic mandatory bolus.

CONCLUSION

No significant differences occurred among all the available administration schemes of neuraxial analgesia. In absence of obstetrical contraindication, neuraxial analgesia has to be considered as the gold standard in obtaining maternal pain relief during labour. The options available in the administration of analgesia should be known and evaluated together by both gynaecologists and anaesthesiologists to choose the best personalized scheme and obtain the best women satisfaction. Since it is difficult to identify comparable circumstances during labour, it is complicate to standardize drugs schemes and their combinations.

Fertility-preserving management of a uterine arteriovenous malformation: a case report of uterine artery embolization (UAE) followed by laparoscopic resection

Herein is presented a fertility-preserving approach in the management of a uterine arteriovenous malformation (AVM) resistant to endovascular management. The patient had a documented AVM and underwent 2 uterine artery embolization procedures, with subsequent recurrence of symptoms. Doppler ultrasound demonstrated recanalization of the AVM. Ultimately, laparoscopic resection of the AVM was performed after laparoscopic ligation of the uterine arteries. Postoperatively, the patient has remained asymptomatic. Laparoscopic resection of a uterine AVM may offer a fertility-preserving alternative to hysterectomy in patients in whom endovascular management has failed.

Transcatheter arterial embolization for secondary postpartum hemorrhage: outcome in 52 patients at a single tertiary referral center

PURPOSE

To assess the safety and efficacy of transcatheter arterial embolization (TAE) for the management of secondary postpartum hemorrhage (PPH) and to determine the factors associated with the clinical outcomes.

MATERIALS AND METHODS

A retrospective analysis of 52 patients (mean age, 31.6 y; range, 25-40 y) undergoing TAE for secondary PPH was performed. Clinical data, including maternal characteristics, delivery details, embolization details, and transfusion requirements, were obtained. Univariate analyses were performed to determine the factors related to clinical outcomes.

RESULTS

The major cause of bleeding was retained placental tissue (44.2%; 23 of 52). Actively bleeding foci were observed in 25 (48.1%) patients. Technical and clinical successes were achieved in 100% and 90.4% (47 of 52) of patients, respectively. Gelatin sponge particles with (n = 10) or without (n = 38) permanent embolic materials, such as microcoils or N-butyl cyanoacrylate, were most commonly used (92.3%; 48 of 52), whereas permanent embolic materials alone were used in 7.7% (4 of 52) of patients. In five patients, embolization failed, and these patients were managed by hysterectomy (n = 3), repeat TAE (n = 1), or conservative management (n = 1). Bleeding control was eventually achieved in all five patients. No maternal risk factors were related to clinical results. The median and mean follow-up periods were 3 months and 12.6 months (range, 1-62 mo). Regular menstruation resumed in all 44 patients with available follow-up, and 5 of the patients became pregnant.

CONCLUSIONS

TAE for secondary PPH is safe and effective and showed technical and clinical success in 100% and 90.4% of patients, respectively. Approximately half of these patients showed a positive bleeding focus, and the use of permanent embolic materials was also common.

Women's choice of positions during labour: return to the past or a modern way to give birth? A cohort study in Italy

Background. Childbirth medicalization has reduced the parturient's opportunity to labour and deliver in a spontaneous position, constricting her to assume the recumbent one. The aim of the study was to compare recumbent and alternative positions in terms of labour process, type of delivery, neonatal wellbeing, and intrapartum fetal head rotation. Methods. We conducted an observational cohort study on women at pregnancy term. Primiparous women with physiological pregnancies and single cephalic fetuses were eligible for the study. We considered data about maternal-general characteristics, labour process, type of delivery, and neonatal wellbeing at birth. Patients were divided into two groups: Group-A if they spent more than 50% of labour in a recumbent position and Group-B when in alternative ones. Results. 225 women were recruited (69 in Group-A and 156 in Group-B). We found significant differences between the groups in terms of labour length, Numeric Rating Scale score and analgesia request rate, type of delivery, need of episiotomy, and fetal occiput rotation. No differences were found in terms of neonatal outcomes. Conclusion. Alternative maternal positioning may positively influence labour process reducing maternal pain, operative vaginal delivery, caesarean section, and episiotomy rate. Women should be encouraged to move and deliver in the most comfortable position.
