Stuck situations in morbidly adherent placenta: how to tackle?

Background: Morbidly adherent placenta is associated with high maternal morbidity and mortality. Its increased prevalence seems to be proportional to the increasing number of caesarean sections. In this study the presentation and management of 32 cases was reviewed with morbidly adherent placenta and maternal and perinatal outcomes from 2014 to 2016, at the hospital.Methods: Study type was retrospective. We reviewed clinical information from patients’ case sheets regarding the risk factors, preparations prior to cesarean section, intraoperative and postoperative complications. Results were interpreted and conclusions were withdrawn.Results: Among the 32 cases, 28 were diagnosed prenatally while 4 were diagnosed intraoperatively. Out of 28 patients, 5 patients were diagnosed early between 14 and 18 weeks of gestational age and other 23 were diagnosed during third trimester by ultrasonography. Caesarean hysterectomy was required in 28 cases.4 were managed conservatively, out of which hysterectomy proved to be necessary in the postpartum period because of severe secondary postpartum hemorrhage in 2 cases. Average no of hospital stay is 10 days ranging from 8-18 days.Conclusions: Prenatal diagnosis of morbidly adherent placenta is essential to plan for the better maternal and perinatal outcome. The decision to perform a cesarean hysterectomy or conservation of uterus (using balloon tamponade or putting haemostatic sutures) is based on the extent of infiltration, the patient’s hemodynamic status, and her desire for future pregnancy. The risk of infection and severe hemorrhage remains high if conservative management is chosen and requires prolonged close monitoring postoperatively. Ideally all the cases should be electively planned and operated by senior surgeon and experienced assistants with senior anesthetist, urosurgeon and physician, with full backup of ICU and blood bank.

The morbidly adherent placenta / La placenta mórbidamente adherida

The incidence of morbidly adherent placentation has increased in the current era of obstetrics paralleling the cesarean rate. The problem of abnormal placental adherence is a significant contributor to maternal morbidity and requires multi-disciplinary care for management. The epidemiology, antenatal diagnosis, and a multidisciplinary care model are presented in this review. Multiple methods of imaging are reviewed in detail. In addition, both surgical and non-surgical interventions for management of the abnormally adherent placenta are evaluated.

La incidencia de placentación adherida mórbidamente ha aumentado en la era actual de la obstetricia, en paralelo con la tasa de cesárea. La adherencia placentaria anormal contribuye significativamente a la morbilidad materna y requiere un manejo multidisciplinario. En esta revisión se presenta la epidemiología, diagnóstico prenatal y un modelo de atención multidisciplinario. Se revisa en detalle los varios métodos de imágenes utilizados en el diagnóstico. Y se evalúa las intervenciones quirúrgicas y no quirúrgicas para el manejo de la placenta adherida anormalmente.

Placenta percreta with a vaginal fistula after successful management by uterine transverse fundal incision and subsequent cesarean hysterectomy

Placenta previa presents a highest risk to pregnancy, and placenta accreta is the most serious. Placenta accreta requires cesarean delivery and often results in massive obstetric hemorrhage and higher maternal morbidity. Challenges associated with cesarean delivery techniques may contribute to increased maternal blood loss and morbidity rates. Several recent obstetric studies reported the usefulness of transverse uterine fundal incision for managing placenta accreta. We present a case of placenta percreta that was treated by a transverse fundal incision. We successfully avoided cutting through the placenta and helped decrease maternal blood loss. After delivery, the patient underwent a cesarean hysterectomy. Postoperative day 48, she experienced watery discharge and was diagnosed with vaginal fistula. We present our case and review the literature.

Relationship between Initial Anesthetic methods and Perioperative Courses in Emergency Cesarean Hysterectomy / 대한산부인과학회지

OBJECTIVE: The Purpose of this study was to compare the perioperative variables in patients administered inhalation or regional anesthesia for the initial cesarean section following emergency hysterectomy under general anesthesia. METHODS: Emergency cesarean hysterectomies performed between January 1993 and December 2004 was analyzed retrospectively. There were 65 emergency cesarean hysterectomies during the period. General anesthesia for both delivery and following hysterectomy was employed 24 cases (General group) and regional anesthesia for the initial cesarean section following general anesthesia for emergency hysterectomy was employed 41 cases (Regional group). RESULTS: Most common indication of cesarean hysterectomy was placenta accreta in the both groups. Incidence of uterine atony without pathology was higher in the regional group than in the general group (34.1% vs. 4.2%). There was no difference in the intraoperative managements, estimated blood loss, and transfusions between the two groups. Total perioperative complications were found in 20 out of 65 cases (28.2%), and the incidence of disseminated intravascular coagulopathy (DIC) was higher in the regional group than in the general group (24.4% vs. 4.2%). CONCLUSION: The anesthetic method did not affect the intraoperative managements although the incidence of uterine atony without pathology was higher, and perioperative DIC was more in the regional group than in the general group.

Clinical Study on Cesarean Hysterectomy / 대한산부인과학회잡지

OBJECTIVE: This article was to review 10 years experience of cesarean hysterectomy at our hospital. To review risk factors, management & outcome of emergency peripartum hysterectomy performed in last 10 years at our hospital. MATERIAL & METHODS: The outcome of 33 cases of cesarean hysterectomy performed at St. Benedict hospital during 10 years from Jan. 1990 to Dec. 1999 was discussed & evaluated. RESULTS: During this time, there was 16014 deliveries, of which 5640 were cesarean section and 25 were cesarean hysterectomies, an incidence of 0.44%, and of which 10374 were vaginal deliveries 8 were. Cesarian hysterectomies are incidence of 0.08%. The age of patients varies from 18 to 42. The higher the age and the parity of patients, the higher incidence of cesarean hysterectomy was noted. The most common indication of cesarean hysterectomy was placental abnormal presentation [placenta accreta (30.3%), placenta previa (27.2%)], uterine atony (33.3%), uterine myoma with pregnancy (6.0%) and Uterine ruture (3.0%). The complication were febrile morbidity, disseminated intravascular coagulopathy and urinary tract injury. There was one maternal death. CONCLUSION: Postoperative complication still remain the causes of maternal morbidity. There careful prenatal care momentary judgement of right operation time, fresh whole blood transfusion and reduction of operation time must be conjunction with maternal life saving. Cesarean delivery, prior cesarean delivery placenta accreta and uterine atony were identified as risk factors for emergency peripartum hysterectomy and abnormal presentation was the primary cause of cesarean hysterectomy. Still, cesarean hysterectomy remains a potentially life saving procedure with which every obstetrician must be familiar.

Clinical Evaluation of Cesarean Hysterectomy / 대한산부인과학회잡지

OBJECTIVES: The aim of this study was to review 10 years' experience of cesarean hysterectomy at our hospital. METHODS: A retrospective study of 37 cases of cesarean hysterectomy between Jan, 1, 1989, and Dec, 31, 1998 was carried out and then method of delivery, maternal age, parity, indication for hysterectomy, amount of transfusion, factors associated with adhesive placenta, and complications of hysterectomy were analysed. RESULTS: The incidence of cesarean hysterectomy was 1 in 639 deliveries. Overall, 0.55% of cesarean sections and 0.02% of vaginal deliveries were followed by cesarean hysterectomy. The higher the age and the parity of patients, the higher incidence of cesarean hysterectomy(p=.000, respectively). The most common indication of cesarean hysterectomy was adhesive placenta(54%). Placenta previa and two more prior cesarean delivery were main risk factors for development of adhesive placenta (Odds ratio: 9.6, 6.1, respectively ; 95% Confidence interval: 2.1-43.5, 1.1-34.2, respectively). Although no maternal deaths occurred, maternal morbidity remained high, including need for transfusion in 29 patients(78%) intraoperative urologic injury in 10 patients(27%), and pulmonary congestion or edema in 7 patients(19%). CONCLUSION: As the incidence of cesarean section and its association with placenta previa and/or accreta continue to rise, we may encounter Cesarean hysterectomy with increasing frequency. Still, cesarean hystere ctomy remains a potentially life saving procedure with which every obstetrician must be familiar.

Clinical Study on Cesarean Hysterectomy / 대한산부인과학회잡지

OBJECTIVE: To study the prevalence, indications, and outcome of cesarean hysterectomy in women delivered at the Gil Medical Center, Gacheon Medical School. METHOD: This is a retrospective study of all cases of cesarean hysterectomy performed between January 1995 and December 1999. RESULTS: The incidence of cesarean hysterectomy was 0.4% (122/31,481). Cesarean hysterectomy was performed in 100 of 17,829 cesarean sections (0.6%) and in 22 of 13,652 vaginal deliveries(0.2%). The higher the age and the parity of patients, the higher the incidence of cesarean hysterectomy was noted. The most common indication of cesarean hysterectomy was uterine atony(50 cases, 41.9%), followed by 25 cases of placenta previa with adhesive placenta(20.5%), 14 cases of adhesive placenta(11.5%), 11 cases of uterine myoma with pregnancy(9.0%), 9 cases of uncontrolled bleeding with placenta previa(7.4%), 7 cases of uterine rupture(5.7%) and 6 cases of extension of uterine incision(4.9%). All patients who had cesarean hysterectomy received transfusion from 0 pint to 78 pints. Live births were 115 cases(94.3%) and 3 infants were still birth(2.5%). Four infants were dead during early neonatal period(3.3%), so perinatal mortality rate was 5.7%. The postoperative complications were bladder injury, ureteral injury, febrile morbidity, disseminated intravascular coagulopathy, hematoma, wound disruption, postpartum cardiomyopathy, and vaginal stump bleeding. There was two maternal deaths due to acute, severe hemorrhage and DIC. CONCLUSIONS: Cesarean hysterectomy remains a necessary procedure for life saving during abdominal and vaginal deliveries. The procedure itself is usually associated with considerable perioperative morbidity. Obstetricians should identify patients at risk and anticipate the procedure and complications.

A Study of Frequency, Indications and Complications on Peripartum Hysterectomy / 대한주산의학회잡지

By means of hospital-based data over 8 years we sought to evaluate the clinical indications and incidence of emergency peripartum hysterectomy by demographic characteristic and reproduction history. From the obstetric record of all deliveries at Chung Goo Hospital between Jan. 1, 1990, and Nov. 31, 1997, we identified all women undergoing emergency cesarean hysterectomy, calculated incidence rates, conducted statistical tests of linear trends and heterogenety, and observed the clinical indicatons preceding the onset of this procedure. There were 16731 deliveries during this period, Cesarean hysterectomy was performed in 24 of 5993 cesarean sections(0.40%) and in 10 of 10738 vaginal deleveries(0.09%), so more frequently after cesarean section than vaginal delivery. The age of patients varied from 22 to 40 years old. The higher the age and the parity of patients, the higher incidence of cesarean hysterectomy was noted. The most common indication of cesarean hysterectomy was uterine atony(52.94%) followed by placental disorders(41.18%), uterine myoma with pregnancy(2.9%) and uterine rupture (2.9%). All patients who had hysterectomy received transfusion from 1 pint to 57 pints. The postoperative complications were bladder injury, febrile morbidity, disseminated intravascular coaguolopathy and wound disruption. There were three maternal deaths, the cause was disseminated intravascular coaguolopathy and amniotic embolism. The data identifiy uterine atony as the primary cause for gravid hysterctomy. The data also illustrated how the incidence of emergency peripartum hysterectomy increases significantly with increasing parity, especially when influenced by a current placenta previa or a prior cesarean section. Maternal morbidity remained high.

A Clinical Survey of Cesarean Hysterectomy / 대한주산의학회잡지

Cesarean hysterectomy remains a necessary procedure for life saving during intractable obstetric hemorrhage. The procedure itself is usually associated with considerable perioperative morbidity, especially when performed under emergency conditions. In this study, the outcomes of 15 cases of cesarean hysterectomy performed at Catholic university of Taegu-Hyosung hospital for 5 years from January, 1993 to December, 1997 were reviewed. There were 22,251 deliveries during this period, cesarean hysterectomy was performed in 13 of 5,753 cesarean section(0.22%) and in 2 of 16,698 vaginal deliveries(0.12%), so more frequently after cesarean section than vaginal deliveries. The age of patients varied from 23 to 39 years old. The higher the age of patients, the higher incidence of cesarean hysterectomy was noted. The most common indication of emergency cesarean hysterectomy was in uterine atony(53.3%), followed by placental disorders(33.3%), uterine rupture(6.7%), and uterine myoma with pregnancy (6.7%). All patients who had cesarean hysterectomy received transfusion from 3 pints to 13 pints. In aspect of fetal outcomes, live birth were 12 cases(80%), one case was fetal death in utero(6.6%), 2 infants were dead during the early neonatal period(13.3%) due to prematurity and RDS (respiratory distress syndrome), so the perinatal mortality rate was 20.0%. The postoperative complications were wound disruption, hematoma, febrile morbidity and disseminated intravascular coagulopathy.

Incidence and risk factors of emergency cesarean hysterectomy.

To identify risk factors associated with emergency cesarean hysterectomy at Siriraj Hospital, medical records of 93 patients who underwent emergency cesarean hysterectomy from January 1986 through December 1995 were retrospectively compared with those of 372 selected controls who underwent cesarean section at the time close to the first group (case : control = 1:4). The incidence of emergency cesarean hysterectomy during the period was 4.07 / 1,000 cesarean sections. Multivariable analysis revealed that age > 35 years (OR=9.7,95% CI : 3.7-24.9), placenta preview (OR = 4.8, 95% CI : 2.2-10.6), age 31-34 years (OR=4.3,95% CI : 1.7-11.3) and parity >3 (OR=3.4,95% CI : 1.6-7.1) were independent factors significantly associated with emergency cesarean hysterectomy (P<0.01). Emergency cesarean hysterectomy remains a necessary procedure for life saving during abdominal delivery. Identification of patients at risk, knowledge of this operation and skill at its performance can be very helpful in reducing maternal morbidity and mortality.

A Clinical Study on Cesarean Hysterectomy / 대한산부인과학회잡지

This study analyzed the outcome of 26 cases of cesarean hysterectomy performed at Wonju Christian Hospital, College of medicine, Yonsei university during 15 years from January, 1982 to May, 1996. There were 27,602 deliveries during this period. Cesarean hysterectomy was performed in 11 of 10,373 cesarean section(0.11 %) and in 15 of 17,229 vaginal deliveries(0.09 %). The age of patients varied from 20 to 48. Indications for emergency cesarean hysterectomy were uterine atony (46.2 %), uterine rupture(26.9 %), and placenta accreta(19.2 %). The relative risk of emergency hysterectomy was 1.22(95 % confidence interval 0.56 to 2.65) for cesarean deliveries, 1.91(95 % confidence interval 0.73 to 4.98) for prior cesarean deliveries and 20.56(95 % confidence interval 10.85 to 38.95) for placenta previa. The patients who had cesarean hysterectomy received from 750 ml to 11,500 ml of blood transfusion with a mean of 3,500 ml. No significant differences in length of operating time, amount of blood loss and postoperative complications were found between total abdominal hysterectomy and subtotal abdominal hysterectomy. In about 1/2 of total patients (46.2 %), there were no operative complications. Maternal death was found in 1 case. Hemorrhage still remains main cause of maternal mortality, the decision of hysterectomy must be conjunction with maternal life saving and free from various dangerous sequalae. So in this study, clinical evaluation for cesarean hysterectomy and an attempt to identify risk factor that might pridict those patients likely to require emergency hysterectomy was made.

Clinical Study on Cesarean Hysterectomy / 대한주산의학회잡지

Cesarean hysterectomy is associated with high risks of severe blood loss, postoperative complication, and maternal morbidity. This study was undertaken to identify the risk factors of cesarean hysterectomy and to reduce the postoperative complications and maternal morbidity. There were 6,362 deliveries between January 1992 and December 1996 at department of obstetrics and gynecology, Inchon Christian Hospital. 1'he results of this study were as follows, 15 cases of cesarean hysterectomy were performed during this period. Cesarean hysterectomy was performed in 10 cases (0.32 %) among 3178 cesarean deliveries and in 5 cases (0.16 %) among 3184 vaginal deliveries. The incidence of cesarean hysterectomy was 0.24 % (15/6,362). The age of patients ranged from 24 to 38 years old. The maternal mortality and morbidity were 0 % (0/15) and 86.7% (13/15), respectively. Indications for cesarean hysterectomy were uterine atony (53.3 %), uterine myoma with pregnancy (20.0 %), placenta accreta and/or increta(20.0 %), and placenta previa (6.7 %) in orders. The associated risk factors of cesarean hysterectomy were prior cesarean delivery (46.7 %) and placenta previa (6.7 %). The postoperative complications were anemia (60.0%), febrile morbidity (13.3 %), paralytic ileus (6.7 %), and wound disruption (6.7 %). We concluded that risk factors of cesarean hysterectomy were cesarean delivery, prior cesarean delivery, uterine myoma with pregnancy, placenta accreta and/or increta, and placenta previa and that sufficient fresh blood and careful prenatal care were needed in risk group of postpartum bleeding.
