Emergency peripartum hysterectomy: experience at a community teaching hospital

OBJECTIVES: To estimate the incidence, indications, risk factors, and complications associated with emergency peripartum hysterectomy at a community-based academic medical center. METHODS: We analyzed retrospectively 47 of 48 cases of emergency peripartum hysterectomy performed at Winthrop-University Hospital from 1991 to 1997. Emergency peripartum hysterectomy was defined as one performed for hemorrhage unresponsive to other treatment less than 24 hours after delivery. Fisher exact test, Wilcoxon rank sum test, and Cochran-Armitage exact trend test were used for analysis. RESULTS: There were 48 emergency peripartum hysterectomies among 34,241 deliveries for a rate of 1.4 per 1000. Most frequent indications were placenta accreta (48.9%, 12 with previa, 11 without previa), uterine atony (29.8%), previa without accreta (8.5%), and uterine laceration (4.3%). Placenta accreta was the most common indication in multiparous women (58.8%, 20 of 34), uterine atony the most common in primiparas (69.2%, nine of 13). Twenty-two of 23 (95.6%) women with placenta accreta had a previous cesarean delivery or curettage. The number of cesarean deliveries or curettages increased the risk of placenta accreta proportionally. Thirty-eight (80.9%) of the hysterectomies were subtotal. Postoperative febrile morbidity was 34%; other morbidity was 26.3%. CONCLUSION: Placenta accreta has become the most common indication for emergency peripartum hysterectomy.     

Peripartum cesarean hysterectomy: critical analysis of risk factors and trends over the years

Objective.?To investigate time trends and risk factors for peripartum cesarean hysterectomy.

Methods.?A population-based study comparing all deliveries that were complicated with peripartum hysterectomy to deliveries without this complication was conducted. Deliveries occurred during the years 1988–2007 at a tertiary medical center. A multiple logistic regression model was constructed to find independent risk factors associated with peripartum hysterectomy.

Results.?Emergency peripartum cesarean hysterectomy complicated 0.06% (n?=?125) of all deliveries in the study period (n?=?211,815). The incidence of peripartum hysterectomy increased over time (1988–1994, 0.04%; 1995–2000, 0.05%; 2001–2007, 0.095%). Independent risk factors for emergency peripratum hysterectomy from a backward, stepwise, multivariable logistic regression model were: uterine rupture (OR?=?487; 95% CI 257.8–919.8, p?<?0.001), placenta previa (OR?=?66.4; 95% CI 39.8–111, p?<?0.001), postpartum hemorrhage (PPH) (OR?=?40.8; 95% CI 22.4–74.6, p?<?0.001), cervical tears (OR?=?22.3; 95% CI 10.4–48.1, p?<?0.001), second trimester bleeding (OR?=?6; 95% CI 1.8–20, p?=?0.003), previous cesarean delivery (OR?=?5.4; 95% CI 3.5–8.4, p?<?0.001), placenta accreta (OR?=?4.7; 95% CI 1.9–11.7, p?=?0.001), and grand multiparity (above five deliveries, OR?=?4.1; 95% CI 2.5–6.6, p?<?0.001). Newborns of these women had lower Apgar scores (<7) at 1 and 5?min (32.7% vs.4.4%; p?<?0.001, and 10.5% vs. 0.6%; p?<?0.001, respectively), and higher rates of perinatal mortality (18.4% vs. 1.4%; p?<?0.001) as compared to the comparison group.

Conclusion.?Significant risk factors for peripartum hysterectomy are uterine rupture, placenta previa, PPH, cervical tears, previous cesarean delivery, placenta accreta, and grand multiparity. Since the incidence rates are increasing over time, careful surveillance is warranted. Cesarean deliveries in patients with placenta previa-accreta, specifically those performed in women with a previous cesarean delivery, should involve specially trained obstetricians, following informed consent regarding the possibility of peripartum hysterectomy.     

Peripartum hysterectomy and associated factors

OBJECTIVE: To identify the risk factors associated with peripartum hysterectomy. STUDY DESIGN: The charts of 101 cesarean hysterectomies performed at Severance Hospital from January 1986 to April 2001 were reviewed. The patients were categorized into 2 groups. One was patients who underwent vaginal delivery followed by peripaRtum hysterectomy. The other was those who had cesarean section followed by peripartum hysterectomy. Paired t test and one-way ANOVA were used for statistical analysis. RESULTS: During the study period there were 31,044 deliveries. Peripartum hysterectomy was performed in 54 of 11,924 cesarean sections (0.45%) and 18 of 19,120 vaginal deliveries (0.09%). The most common indication for peripartum hysterectomy was uterine atony (41.58%), followed by placenta previa accreta (23.76%), placenta accreta (16.83%) and placenta previa (11.88%). Placenta previa accreta patients received the highest volume of transfusions, 1,734 +/- 688 mL (P < .05). More cesarean hysterectomies (55.93%) occurred in emergency cesarean section cases than in elective ones (44.06%). CONCLUSION: The risk factors associated with peripartum hysterectomy were placental abnormalities and previous cesarean deliveries. Hemorrhage remained the main cause of maternal mortality. Therefore, peripartum hysterectomy must be performed to save the life of the mother and must be free of dangerous sequelae.     

Incidence of emergency peripartum hysterectomy in Ain-shams University Maternity Hospital,Egypt: a retrospective study

Purpose

To estimate the incidence of emergency peripartum hysterectomy over 6 years in Ain-shams University Maternity Hospital.

Methods

Detailed chart review of all cases of emergency peripartum hysterectomy, 2003–2008, including previous obstetric history, details of the index pregnancy, indications for emergency peripartum hysterectomy, outcome of the hysterectomy and infant morbidity.

Results

The overall rate of emergency peripartum hysterectomy was 149 of 66,306 or 2.24 per 1,000 deliveries. The primary indications for hysterectomies were placenta accreta/increta 59 (39.6 %), uterine atony 37 (24.8 %), uterine rupture 35 (23.5 %) and placenta previa without accreta 18 (12.1 %). After hysterectomy, 115 (77 %) women were admitted to the intensive care unit. Women were discharged home after a mean 11.2 day length of stay. Using multifactorial logistic regression analysis, we found that woman’s age, atonic uterus, placenta accreta/increta, previous cesarian section and ruptured uterus were independent predictors for peripartum hysterectomy

Conclusion

Abnormal placentation was the main indication for peripartum hysterectomy. The risk factors for peripartum hysterectomy were morbid adherence of placentae in scared uteri, uterine atony and uterine rupture. The most important step in prevention of major postpartum hemorrhage is recognizing and assessing women’s risk. The risk of peripartum hysterectomy seems to be significantly decreased by limiting the number of cesarean section deliveries, thus reducing the occurrence of abnormal placentation in the form of placenta accreta, increta or percreta.     

Peripartum hysterectomy in 38 hospitals in China: a population-based study

Objective

To investigate the incidence, indications, risk factors and transfusions of peripartum hysterectomy in China.

Methods

A population-based study was conducted using inpatient records of 38 hospitals between 1 January 2011 and 31 December 2011; multivariate logistic regression analysis was used to identify independent risk factors for peripartum hysterectomy.

Results

During the study period, there were 43 peripartum hysterectomy cases out of 114,420 deliveries (0.38 ‰). Abnormal placentation was major indication for peripartum hysterectomy. Several factors significantly increased the risk of peripartum hysterectomy in this population: placenta previa/accreta [adjusted odds ratio (aOR) 49.7, 95 % CI 25.0–98.9], maternal age ≥35 years (aOR 8.1, 95 % CI 4.0–16.0), preeclampsia/eclampsia (aOR 7.5, 95 % CI 2.6–21.7), cesarean delivery (aOR 3, 95 % CI 1.1–8.0), and multiparity (aOR 2.7, 95 % CI 1.2–5.4). In contrast, multiple gestations did not.

Conclusions

Placenta previa/accreta, maternal age ≥35 years, preeclampsia/eclampsia, cesarean delivery and multiparity were risk factors of peripartum hysterectomy.     

Abnormal placentation: twenty-year analysis

OBJECTIVE: This study was undertaken to determine whether the rate of abnormal placentation is increasing in conjunction with the cesarean rate and to evaluate incidence, risk factors, and outcomes. STUDY DESIGN: Cases from 1982-2002 were identified by histopathologic or strong clinical criteria. Risk factors were assessed in a matched case-control study, and analyzed using conditional logistic regression models. RESULTS: There were 64,359 deliveries, with cesarean rates increasing from 12.5% (1982) to 23.5% (2002). The overall incidence of placenta accreta was 1 in 533. Significant risk factors for placenta accreta in our final analysis included advancing maternal age (odds ratio [OR] 1.13, 95% CI 1.089-1.194, P < .0001), 2 or more cesarean deliveries (OR 8.6, 95% CI 3.536-21.078, P < .0001), and previa (OR 51.4, 95% CI: 10.646-248.390, P < .0001). CONCLUSION: The rate of placenta accreta increased in conjunction with cesarean deliveries; the most important risk factors were previous cesarean delivery, previa, and advanced maternal age.     

Placenta previa accreta

OBJECTIVES: The purpose of our study was to assess the relationship between previous cesarean section and placenta previa accreta and to estimate the incidence of placenta accreta et previa accreta as the indication for peripartum hysterectomy. MATERIALS AND METHODS: The records of all patients delivered with the diagnosis of placenta previa accreta during the period from 1992-2002 at Hospital in Chojnice were reviewed. Statistical analyses were carried out to determine the relationship between previous cesarean section and subsequent development of placenta previa accreta. We conducted a retrospective analysis of indications for peripartum hysterectomy. RESULTS: From a total 28,177 women, who delivered at the Chojnice Hospital, 15(0.05%) patients had placenta accreta, 63(0.2%) placenta previa. Among placenta previa deliveries 22(34.9%) patients had previous cesarean section. Out of 15 patients with placenta accreta 10(66.7%) had placenta previa. Incidence of placenta accreta per case of placenta previa was 158.7 per 1000. The incidence of placenta previa accreta significantly increased in those with previous post cesarean scars. This incidence increased as the number of previous cesarean sections increased. The most common indication for peripartum hysterectomy was placenta accreta--48.4%, incidence of placenta previa accreta was accounts for 32.3% of all indications. CONCLUSIONS: The association between placenta previa accreta and prior cesarean section was confirmed. The incidence of placenta accreta increased as the number of previous cesarean sections increased. Patients with an antepartum diagnosis of placenta previa, who have had a previous cesarean section should be considered at high risk for developing placenta accreta. The most common indication for peripartum hysterectomy in this study was placenta previa accreta.     

Prediction of peripartum hysterectomy and end organ dysfunction in major obstetric haemorrhage

Objectives

The aims of this study are to determine the incidence and aetiology of major obstetric haemorrhage (MOH) in our population, to examine the success rates of medical and surgical interventions and to identify risk factors for peripartum hysterectomy and end organ dysfunction (EOD).

Study design

This prospective study from 2004 to 2007 was carried out in three Dublin maternity hospitals. Women were identified as having MOH if they received ≥5 units of red cell concentrate (RCC) acutely. Risk factors for hysterectomy or end organ dysfunction were calculated using logistic regression.

Results

One hundred and seventeen cases of MOH in 93,291 deliveries were identified (1.25/1000). The predominant cause was uterine atony. Haemostasis was achieved with medical therapy alone in 15% of cases. The hydrostatic balloon and the B-Lynch suture arrested bleeding in 75% and 40% of cases utilised respectively. Hysterectomy was required to arrest bleeding in 24% of women and 16% of women developed end organ dysfunction (11 had both). There was one maternal death. Independent risk factors for hysterectomy included the number of previous caesarean sections (OR 3.28, 95% CI 1.95-5.5), placenta praevia (OR 13.5, 95% CI 7.7-184), placenta accreta (OR 37.7, 95% CI 7.7-184), uterine rupture (OR 7.25, 95% CI 1.25-42) and the number of units of RCC transfused (OR 1.31, 95% CI 1.13-1.5). Independent risk factors for end organ dysfunction (EOD) were placenta accreta (OR 5, 95% CI 1.5-16.5), uterine rupture (OR 13.86, 95% CI 2.32-82), the number of RCC transfused (OR 1.31, 95% CI 1.13-1.5) and the minimum haematocrit recorded (OR 5.53, 95% CI 1.7-18).

Conclusions

MOH is complicated by hysterectomy in 24% and end organ dysfunction in 16% of cases. The risk of peripartum hysterectomy is increased with the number of previous caesarean sections, the aetiology of the bleed, namely placenta praevia/accreta or uterine rupture and the volume of blood transfused. Critically, failure to maintain optimal haematocrit during the acute event was associated with end organ dysfunction.     

Indication of emergency peripartum hysterectomy: review of 17 cases

OBJECTIVES: The objectives were to determine the incidence, indications, associated risk factors and complications with emergency peripartum hysterectomy at King Abdulaziz University Hospital, Saudi Arabia. METHODS: This is a retrospective analysis of 17 cases of emergency peripartum hysterectomy done from January 1, 1991 to December 31, 2002. RESULTS: Seventeen patients of emergency peripartum hysterectomy were identified among 34,379 deliveries and the incidence rate was 0.5 per 1,000. Uterine atony 11 (64.7%, 9 without previa and 2 with previa) and followed by morbid adherent placenta with previa 6 (35.3%, 1 complete placenta accreta and 5 partial adherent placenta) was the most common indication of hysterectomy. Of the atonic group, 3 were primigravidae, 2 of 3 induced and 1 placenta previa. In morbid adherent placenta group the gravidity, previous abortions and prior cesarean deliveries were higher compared to the atonic group and were statistically significant. Conservative surgery performed in 6 (35.3%) patients before proceeding to hysterectomies, 3 (17.7%) patients had uterine artery ligation and 3 (17.7%) internal iliac ligation. Eight (47.1%) hysterectomies were subtotal. Nine (53%) patients developed disseminated intravascular coagulopathy (DIC) and one case (6%) had bilateral ureteric ligation and bladder injury. No maternal deaths occurred. CONCLUSION: Uterine atony still is the leading cause of primary postpartum hemorrhage and the main indications of emergency peripartum hysterectomy. The combination of high parity, cesarean section, prior cesarean delivery and current placenta previa were identified as risk factors, and should alert the obstetrician that an emergency peripartum hysterectomy may needed. Although no maternal mortality occurred morbidity remained high.     

Placenta previa: obstetric risk factors and pregnancy outcome.

OBJECTIVE: To determine the incidence, obstetric risk factors and perinatal outcome of placenta previa. STUDY DESIGN: All singleton deliveries at our institution between 1990 and 1998 complicated with placenta previa were compared with those without placenta previa. RESULTS: Placenta previa complicated 0.38% (n = 298) of all singleton deliveries (n = 78 524). A back-step multiple logistic regression model found the following factors to be independently correlated with the occurrence of placenta previa: maternal age above 40 years (OR 3.1, 95% CI 2.0-4.9), infertility treatments (OR 3.1, 95% CI 1.8-5.6), a previous Cesarean section (OR 1.8, 95% CI 1.4-2.4), a history of habitual abortions (OR 1.3, 95% CI 1.3-2.7) and Jewish ethnicity (OR 1.3, 95% CI 1.1-1.8). Pregnancies complicated with placenta previa had significantly higher rates of second-trimester bleeding (OR 156.0, 95% CI 87.2-277.5), pathological presentations (OR 7.6, 95% CI 5.7-10.1), abruptio placentae (OR 13.1, 95% CI 8.2-20.7), congenital malformations (OR 2.6, 95% CI 1.5-4.2), perinatal mortality (OR 2.6, 95% CI 1.1-5.6), Cesarean delivery (OR 57.4, 95% CI 40.7-81.4), Apgar scores at 5 min lower than 7 (OR 4.4, 95% CI 2.3-8.3), placenta accreta (OR 3.6, 95% CI 1.1-9.9) postpartum hemorrhage (OR 3.8, 95% CI 1.2-10.5), postpartum anemia (OR 5.5, 95% CI 4.4-6.9) and delayed maternal and infant discharge from the hospital (OR 10.9, 95% CI 7.3-16.1) as compared to pregnancies without placenta previa. In a multivariable analysis investigating risk factors for perinatal mortality, the following were found to be independent significant factors: congenital malformations, placental abruption, pathological presentations and preterm delivery. In contrast, placenta previa and Cesarean section were found to be protective factors against the occurrence of perinatal mortality while controlling for confounders. CONCLUSION: Although an abnormal implantation per se was not an independent risk factor for perinatal mortality, placenta previa should be considered as a marker for possible obstetric complications. Hence, the detection of placenta previa should encourage a careful evaluation with timely delivery in order to reduce the associated maternal and perinatal complications.     

Placenta previa: obstetric risk factors and pregnancy outcome

Objective: To determine the incidence, obstetric risk factors and perinatal outcome of placenta previa. Study design: All singleton deliveries at our institution between 1990 and 1998 complicated with placenta previa were compared with those without placenta previa. Results: Placenta previa complicated 0.38% ( n = 298) of all singleton deliveries ( n = 78 524). A back-step multiple logistic regression model found the following factors to be independently correlated with the occurrence of placenta previa: maternal age above 40 years (OR 3.1, 95% CI 2.0-4.9), infertility treatments (OR 3.1, 95% CI 1.8-5.6), a previous Cesarean section (OR 1.8, 95% CI 1.4-2.4), a history of habitual abortions (OR 1.3, 95% CI 1.3-2.7) and Jewish ethnicity (OR 1.3, 95% CI 1.1-1.8). Pregnancies complicated with placenta previa had significantly higher rates of second-trimester bleeding (OR 156.0, 95% CI 87.2-277.5), pathological presentations (OR 7.6, 95% CI 5.7-10.1), abruptio placentae (OR 13.1, 95% CI 8.2-20.7), congenital malformations (OR 2.6, 95% CI 1.5-4.2), perinatal mortality (OR 2.6, 95% CI 1.1-5.6), Cesarean delivery (OR 57.4, 95% CI 40.7-81.4), Apgar scores at 5 min lower than 7 (OR 4.4, 95% CI 2.3-8.3), placenta accreta (OR 3.6, 95% CI 1.1-9.9) postpartum hemorrhage (OR 3.8, 95% CI 1.2-10.5), postpartum anemia (OR 5.5, 95% CI 4.4-6.9) and delayed maternal and infant discharge from the hospital (OR 10.9, 95% CI 7.3-16.1) as compared to pregnancies without placenta previa. In a multivariable analysis investigating risk factors for perinatal mortality, the following were found to be independent significant factors: congenital malformations, placental abruption, pathological presentations and preterm delivery. In contrast, placenta previa and Cesarean section were found to be protective factors against the occurrence of perinatal mortality while controlling for confounders. Conclusion: Although an abnormal implantation per se was not an independent risk factor for perinatal mortality, placenta previa should be considered as a marker for possible obstetric complications. Hence, the detection of placenta previa should encourage a careful evaluation with timely delivery in order to reduce the associated maternal and perinatal complications.     

Multiple cesarean section morbidity.

OBJECTIVE: To quantify maternal risk associated with multiple cesarean sections (CSs) and determine whether the third CS defines a threshold for increased morbidity. METHODS: From January 1997 to January 2002, the clinical records of 3191 women who were delivered by CS at our referral maternity center were examined for selected indicators of maternal morbidity. The women were assigned to groups based on number of CSs and the frequency of each indicator was determined. A composite score for each indicator among women grouped by number of consecutive CSs was then derived to compare risk between groups and against the third CS. RESULTS: By all indicators studied, morbidity increased with successive CSs before and through the third CS. However, compared with the third, the risk of major morbidity was significantly increased with the fifth, and much worse at the sixth CS for placenta previa (odds ratio [OR]=3.8, 95% confidence interval [CI]=1.9-7.4), placenta accreta (OR=6.1, 95% CI=2.0-18.4) and hysterectomy (OR=5.9, 95% CI=1.5-24.4). But the third and fourth CSs had the same risk of major morbidity for placenta previa (OR=1.4, 95% CI=0.8-2.2), placenta accreta (OR=1.0, 95% CI=0.3-2.9) and hysterectomy (OR=0.3, 95% CI=0.0-2.7). CONCLUSIONS: The third CS does not define a threshold for increased risk to the mother. Instead, overall morbidity rises continually with each successive CS. However, specifically for major morbidity from the triad of placenta previa, placenta accreta and hysterectomy during CS, the fourth CS carries the same risk as the third.     

Emergency peripartum hysterectomy in a tertiary London hospital

Objective The objective was to review all emergency peripartum hysterectomies performed at a tertiary hospital in London, UK, and to identify the risk factors for emergency peripartum hysterectomy.Method A retrospective case control study. The cases consisted of all women who had emergency peripartum hysterectomy between 1 January 1993 and 31 December 2003. Controls were women who delivered immediately before and after the indexed case. Demographic data, medical and surgical histories, pregnancy, intrapartum and postpartum data were collected. Differences between cases and controls were compared with ², Fisher exact and Student t tests. Multiple logistic regression analysis was performed to identify independent risk factors for emergency peripartum hysterectomy.Results There were 15 cases of emergency peripartum hysterectomy in 31,079 deliveries, giving a rate of 0.48 per 1,000. Women who had emergency peripartum hysterectomy were significantly older (mean age 37 years vs. 29 years, P<0.001) and multiparous (P=0.02). More of the cases had a history of uterine surgery (67 vs. 30%, P=0.01), placenta praevia (60 vs. 3%, P<0.0001) and were delivered by caesarean section (86.7 vs. 30%, P=0.003). Eighty percent of the hysterectomies were performed in the daytime and all were done by consultants. Haemorrhage due to placenta praevia was the main indication for emergency peripartum hysterectomy (47%). Independent risk factors for emergency peripartum hysterectomy were older age (odds ratios [OR] 1.2, 95% confidence interval [95% CI] 1.2–1.6), multiparity (OR 2.6, 95% CI 1.3–10.2), history of previous caesarean section (OR 13.5, 95% CI 2.7–65.4), caesarean delivery in index pregnancy (OR 11.6, 95% CI 2.1–68.6) and caesarean delivery in index pregnancy for placenta praevia (OR 18, 95% CI 3.6–69).Conclusion Caesarean deliveries, especially repeat caesareans in women with placenta praevia, significantly increase the risk of emergency peripartum hysterectomy.     

Emergency peripartum hysterectomy: a 9-year review

Objective: To determine the incidence, indications, risk factors, and complications of emergency peripartum hysterectomy. Study design: A retrospective study of the patients requiring an emergency peripartum hysterectomy of a 9-year period was conducted. Emergency peripartum hysterectomy was defined as one performed for hemorrhage unresponsive to other treatment less than 24 h after delivery. Demographic and clinical variables were obtained from the maternal records. Results: There were 34 emergency peripartum hysterectomies out of 117,095 deliveries for a rate of 0.29 per 1,000. Of the 16 cases that were delivered by cesarean section, seven had a previous cesarean section and 18 cases were delivered vaginally, including two using vacuum extraction. Total hysterectomy was performed in 24 patients, and subtotal hysterectomy in ten patients. The indications for hysterectomy were uterine rupture (n=12), placenta accreta (n=10), uterine atony (n=7), and hemorrhage (n=5). There were two maternal deaths, six stillbirths, and two early neonatal deaths. Conclusion: This study identified surgical deliveries, uterine rupture, placenta accreta, and uterine atony as risk factors for emergency peripartum hysterectomy. The most common reason for abnormal placental adherence was a previous cesarean section. Multiparity and oxytocin use for uterine stimulation were among the risk factors for uterine atony that necessitated emergency peripartum hysterectomy.     

Emergency peripartum hysterectomy in a tertiary hospital in Ankara, Turkey: a 5-year review

Purpose

To determine the incidence, indications and the risk factors of emergency peripartum hysterectomy (EPH).

Methods

We analyzed retrospectively 30 cases of emergency peripartum hysterectomy performed at the Obstetrics Department of a tertiary, research and education hospital between the years of 2006 and 2010. Demographic, medical and clinical data of the patients were recorded. Data stored were expressed as mean?±?standard deviation.

Results

There were 30 cases of EPH among 82,363 deliveries. The overall incidence of EPH was 0.364 per 1,000 deliveries from 2006 to 2010. Nine hysterectomies were performed after vaginal delivery (0.16/1,000 vaginal deliveries) and the remaining 21 hysterectomies were performed after cesarean section (0.78/1,000 cesarean sections). Two cases (6.7?%) were performed as subtotal and remaining 28 cases (93.3?%) were performed as total hysterectomy. Indications of EPH were uterine atony (43.3?%, 13/30), placenta accreta (40.0?%, 12/30) and uterine rupture (16.7?%, 5/30). All patients [7/7 (100?%)] with placenta previa and 11 of 12 patients (91.7?%) with placenta accreta had previously cesarean sections. There were two maternal deaths due to coagulopathy and pulmonary embolism. Two stillbirths (6.6?%) and 2 early neonatal deaths (6.6?%) were recorded.

Conclusions

It should be kept in mind that cases of placenta previa and/or placenta accreta with previous cesarean sections have a very high probability of EPH. The delivery should be performed in suitable clinical settings with experienced surgeons when the risk factors like placenta previa and/or placenta accreta are determined so as to achieve optimal outcome.     

Obstetric hysterectomy: Ramathibodi's experience 1969-1987.

Obstetric hysterectomy was performed on 121 women at Ramathibodi Hospital, Bangkok, between 1969 and 1987, an incidence of 1:875 deliveries. Of 88 women whose records were available, 91% had emergency hysterectomy, with uterine atony as the most common indication (32.5%), followed by placenta accreta (26.2%), uterine rupture (10.0%), extension of cervical tear to the lower uterine segment (8.7%), broad ligament hematoma (6.2%) and placenta previa (5.0%). The intraoperative and postoperative problems included febrile morbidity (52%), intraoperative hypotension (41%), and disseminated intravascular coagulation (5.7%). Late complications included Sheehan's syndrome (3.4%), post-transfusion hepatitis (2.3%), hematoma (2.3%) and wound infection (2.3%).     

Emergency peripartum hysterectomy at the Princess Badeea Teaching Hospital in north Jordan.

OBJECTIVE: To study the prevalence, indications and outcome of emergency peripartum hysterectomy in women delivered at the Princess Badeea Teaching Hospital in North Jordan. METHOD: This is a retrospective study of all cases of emergency peripartum hysterectomy performed between 1st of January 1994 and 31 August 1998. RESULTS: During the study period there were a total of 21 emergency peripartum hysterectomy were performed. The overall incidence was 0.5/1,000 deliveries. The mean age of patients was 34.7 +/- 3.9 years, the median parity was 6 and the mean gestational age was 36.9 +/- 2.01 weeks. There were 19 cases of caesarean hysterectomy. The leading indication for caesarean section was previous caesarean section (89.5%), placenta previa alone (10.5%). It should be noted that 7 cases with previous caesarean section also had placenta previa (41.2%). The main indications for emergency hysterectomy were, abnormally adherent placenta was the leading indication (38.1%), followed by rupture uterus (33.3%), haemorrhage and uterine atony occurred in 14.3% of cases each, maternal complications occurred in 42.9% of cases postoperatively. There were 4 cases of stillbirths and 2 cases of neonatal deaths. CONCLUSION: Peripartum hysterectomy remains a necessary procedure for life saving during abdominal and vaginal deliveries. The procedure itself is usually associated considerable perioperative morbidity. Obstetricians should identify patients at risk and anticipate the procedure and complications.     

Risk Factors and Pregnancy Outcome in Different Types of Placenta Previa

ObjectiveTo compare risk factors and pregnancy outcome between different types of placenta previa (PP).Materials and MethodsWe conducted a retrospective study of 306 women presenting with PP over a 10-year period from January 1996 to December 2005. Differences between women with major and minor PP regarding age, parity, history of Caesarean section, antepartum hemorrhage, preterm deliveries, placenta accreta, Caesarean hysterectomy, operative complications, and neonatal outcome were identified using Mann-Whitney U test, chi-square test, and multivariate logistic regression.ResultsThe overall incidence of PP was 0.73%. Major PP (complete or partial PP) occurred in 173 women (56.5%) and minor PP (marginal PP or low-lying placenta) in 133 women (43.5%). There were no differences between women with major and minor PP regarding age, parity, and previous miscarriages. After controlling for confounding factors, women with major PP showed a significantly higher incidence of antepartum hemorrhage (OR 3.18; 95% CI 1.58–6.4, P = 0.001), placenta accreta (OR 3.2; 95% CI 1.22–8.33, P = 0.017), and hysterectomy (OR 5.1; 95% CI 1.31–19.86, P = 0.019). Antepartum hemorrhage in women with PP was associated with premature delivery (OR 14.9; 95% CI 4.9–45.1, P < 0.001), more commonly in women with major PP. The only significant difference between women with major and minor PP regarding neonatal outcome was that major PP was associated with a higher incidence of admission to the neonatal intensive care unit (P = 0.014).ConclusionComplete or partial placenta previa is associated with higher morbidity than marginal placenta previa or low-lying placenta.     

Peripartum hysterectomy in Taiwan

OBJECTIVE: To investigate the incidence and associated risk factors for peripartum hysterectomy in singleton pregnancies. METHODS: A retrospective cohort study of all women with singleton pregnancies admitted for delivery in 2002 taken from the National Healthcare Insurance database. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for maternal and hospital characteristics using logistic regression. RESULTS: There were 287 peripartum hysterectomies in 214 237 singleton pregnancies (0.13%). Cesarean delivery, vaginal birth after cesarean (VBAC), and repeat cesarean delivery had higher hysterectomy rates than vaginal delivery, with adjusted ORs of 12.13 (95% CI 8.30-17.74), 5.12 (95% CI 1.19-21.92), and 3.84 (95% CI 2.52-5.86), respectively. Pregnancies complicated with placenta previa, gestational diabetes mellitus (GDM), and premature labor were associated with significantly increased risks for peripartum hysterectomy (P<0.05). CONCLUSION: Risk factors for peripartum hysterectomy included cesarean delivery, VBAC, repeat cesarean, placenta previa, GDM, and premature labor. VBAC and repeat cesarean had a similar risk.
