RESUMO
BACKGROUND: Placenta previa accreta (PPA) is a severe obstetric condition that can cause massive postpartum hemorrhage and transfusion. Cesarean hysterectomy is necessary in some severe cases of PPA to stop the life-threatening bleeding, but cesarean hysterectomy can be associated with significant surgical blood loss and major complications. The current study is conducted to investigate the potential risk factors of excessive blood loss during cesarean hysterectomy in women with PPA. METHODS: This is a retrospective study including singleton pregnancies after 28 weeks of gestation in women with placenta previa and pathologically confirmed placenta accreta spectrum who received hysterectomy during cesarean sections. A total of 199 women from January 2012 to August 2023 were included in this study and were divided into Group 1 (estimated surgical blood loss (EBL) ≤ 3500 mL, n = 103) and Group 2 (EBL > 3500 mL, n = 96). The primary outcome was defined as an EBL over 3500 mL. Baseline characteristics and surgical outcomes were compared between the two groups. A multivariate logistic regression model was applied to find potential risk factors of the primary outcome. RESULTS: Massive surgical blood loss was prevalent in our study group, with a median EBL of 3500 mL. The multivariate logistic analysis showed that emergency surgery (OR 2.18, 95% CI 1.08-4.41, p = 0.029), cervical invasion of the placenta (OR 2.70, 95% CI 1.43-5.10, p = 0.002), and intraoperative bladder injury (OR 5.18, 95% CI 2.02-13.28, p = 0.001) were all associated with the primary outcome. Bilateral internal iliac arteries balloon occlusion (OR 0.57, 95% CI 0.34-0.97) and abdominal aortic balloon occlusion (OR 0.33, 95% CI 0.19-0.56) were negatively associated with the primary outcome. CONCLUSIONS: Emergency surgery, cervical invasion of the placenta, and intraoperative bladder injury were potential risk factors for additional EBL during cesarean hysterectomy in women with PPA. Future prospective studies are needed to confirm the effect of intra-arterial balloon occlusion in cesarean hysterectomy of PPA.

OBJECTIVES: To assess the reliability of placental magnetic resonance imaging measurements in predicting peripartum hysterectomy and neonatal outcomes in patients with total placenta previa. STUDY DESIGN: This retrospective cohort study, conducted at a single tertiary center, identified 372 pregnant women diagnosed with placenta previa. 277 singleton pregnancies that met the inclusion criteria and were diagnosed with total placenta previa in the third trimester were divided into two groups according to whether a placental MRI was performed. Two radiologists analyzed the MRI findings of 150 pregnant women with total placenta previa. Measurements were conducted for the placental volume of the upper and lower uterine sectors, cervical canal length, and cervical canal dilatation. A comparison was made between the surgical progression of these pregnant women and 127 pregnant women with total placenta previa who did not undergo an MRI. After pathological examination, 122 (63.2%) of 193 pregnant women diagnosed with placenta accreta spectrum underwent peripartum total abdominal hysterectomy. The results were compared using logistic regression analysis. RESULTS: Reduced placental volume in the upper uterine segment and increased volume in the lower uterine segment significantly correlated with a higher probability of peripartum hysterectomy (cut-off: ≤343.4 and ≥ 403.4 cm3; OR: 0.993, 95 % CI: 0.990-0.995 and OR: 1.007, 95 % CI: 1.005-1.009, respectively). Shortened cervical canal length and increased dilatation raise the risk of peripartum hysterectomy (cut-off: ≤34, ≥11 mm; OR: 0.82, 95 % CI: 0.77 - 0.88 and OR: 1.7, 95 % CI: 1.4 - 2.1, respectively). The risk of neonatal death is 32 times higher in those < 34 weeks than in those 34 weeks or higher (95 % CI: 4.2-250, p = 0.001). CONCLUSIONS: Placental MRI significantly contributes to predicting peripartum total abdominal hysterectomy and neonatal mortality in patients with total placenta previa associated with placenta accreta spectrum.

OBJECTIVES: Placenta previa-accreta spectrum disorders are a cause of obstetric hemorrhage that can lead to maternal fetal mortality and morbidity. We aimed to describe the use of a uterine isthmic tourniquet left in situ as a new uterus-preserving approach for patients with placenta previa-accreta. METHODS: In this retrospective comparative study, the patients who underwent surgery for placenta previa between 2017 and 2024 at our tertiary hospital were reviewed. Primary outcome of the study is to evaluate feasibility of uterine isthmic tourniquet left in situ for uterine preserving by preventing postpartum hemorrhage for patients with placenta previa-accreta. As a secondary outcome, group 1 (n=28) patients who were managed with uterine isthmic tourniquet left in place were compared with patients in group 2 (n=32) who were managed with only bilateral uterine artery ligation. RESULTS: This new approach uterine isthmic tourniquet technique prevented postpartum hemorrhage with a rate of 100 percent in group 1 patients, while uterine artery ligation prevented postpartum hemorrhage with a rate of 75â¯% in group 2. Postoperative additional interventions (relaparotomy hysterectomy, balloon tamponade application, uterine or vaginal packing) were performed for eight patients in group 2 (25â¯%) but not in group 1 (0â¯%) (p=0.015). The haemoglobin levels before caesarean section were similar in both groups (p=0.235), while the postoperative haemoglobin levels were lower in group 2 (9.69 ± 1.37 vs. 8.15 ± 1.32) (p=0.004). Erythrocyte suspension was given to two patients in group 1 and 12 patients in group 2 (2/28 7â¯% vs. 12/32 37â¯%, p=0.018). CONCLUSIONS: The uterine isthmic tourniquet left in situ technique is a safe, simple and effective for preventing postpartum hemorrhage and preserving uterus during placenta previa accreta surgery as superior to uterine artery ligation alone.

CASE PRESENTATION: A 35-year-old woman at 36 weeks and 4 days gestation with known complete anterior placenta previa and no other medical history presented for routine obstetric follow-up. She reported increasing fatigue in the prior week but otherwise endorsed no new concerns. She denied recent vaginal bleeding or discharge, abdominal pain, contractions, or extremity swelling. On evaluation, her BP was 126/74 mm Hg with a heart rate of 72 beats per min. The results from the physical examination were normal. There was a category II fetal heart rate tracing and a 6/10 biophysical profile (ie, no fetal breathing movements, nonreactive nonstress test), which prompted referral to the hospital. On admission, sonogram confirmed cephalic presentation and redemonstrated complete anterior placenta previa with no evidence of hemorrhage. She received antenatal steroids and was scheduled for a cesarean section delivery. She received bupivacaine spinal anesthesia for the procedure. The surgical procedure progressed with a low transverse uterine incision and subsequent delivery of the baby with no complications noted. Immediately after delivery of the baby and during gentle traction of the placenta, the patient experienced rapid cardiovascular collapse in the form of hypotension and bradycardia.

In the case of placenta previa-accreta when the placenta covers the entire anterior uterine wall, it is difficult to avoid transecting the placenta by traditional low-transverse cesarean section (CS), resulting in catastrophic hemorrhage and fetal anemia. To prevent this critical risk, we developed the CS with transverse uterine fundal incision (TUFI) and this technique has been widely used as a beneficial surgical method in clinical practice owing to its safety advantages for the mother and neonate since our first report. However, the risk of uterine rupture during a subsequent pregnancy remains unclear. Based on our 17 years of experience, patients who require TUFI do not need to avoid this beneficial operative method simply because of their desire to conceive again, as long as certain conditions can be met. To approve a post-TUFI pregnancy, an appropriate suture method, delay in conception for at least 12 months with evaluation of the TUFI scar, and cautious postoperative management are at a minimum essential. In this article, we showed our recommendation for operative procedure and discuss the current status of the management of post-TUFI pregnancies based on the evaluation of the TUFI wound scar and experience with postoperative pregnancies.

Background: This study is aimed at evaluating the conservative surgical treatment of patients with placenta accreta spectrum (PAS) disorder and at presenting the experience of a single surgeon. Materials and Methods: This retrospective study included 245 patients with placenta previa accompanied by PAS disorders operated at a university hospital between June 2013 and December 2023. The diagnosis of PAS was made by a single perinatologist using a combination of transvaginal and transabdominal ultrasonography. All patients were operated with conservative surgical technique by the same surgeon. The demographic and clinical characteristics of the patients, the anesthesia and incision types used, and the details of the surgical technique were evaluated. Results: Of the patients, 165 were operated on at the scheduled time, 80 were operated on under emergency conditions, and 232 (94.69%) of them were operated on under spinal anesthesia. All patients were operated on with a Pfannenstiel incision followed by a transverse incision to the upper border of the placenta to enter into the uterus. An average of 0.52 units of red blood cells per patient was transfused to all patients. Spontaneous intra-abdominal bleeding developed in five patients, and surgical complications occurred in eight patients. No cesarean hysterectomy was performed, and no maternal mortality was detected in any of the cases. The mean time duration of surgery was 54.44 ± 11.37 (30-90) min, and the mean length of hospital stay was 1.71 ± 1.30 (1-9) days. Conclusions: We recommend this procedure as a novel technique and a robust and safe alternative to peripartum hysterectomy and other conservative surgical management procedures for cases with complete PP accompanied with PAS. This technique preserves the uterus as well as reduces blood loss, and transfusion requirement, and thus maternal morbidity and mortality in PAS cases.

BACKGROUND: Births at advanced maternal ages (≥ 35 years) are increasing. This has been associated with a higher incidence of placenta previa, which increases bleeding risk. Hybrid operating rooms, designed to accommodate interventions and cesarean sections, are becoming more prominent because of their dual capabilities and benefits. However, they have been associated with increased postoperative hypothermia in pediatric settings; moreover, this has not been studied in pregnant women with placenta previa. METHODS: This retrospective cohort study included pregnant women diagnosed with placenta previa who underwent elective cesarean section under general anesthesia between May 2019 and 2023. The patients were categorized according to the operating room type. The primary outcome was to determine whether the hybrid operating room is a risk factor for immediate postoperative hypothermia, defined as a tympanic membrane temperature below 36.0°C. The secondary outcomes were the effects of immediate postoperative hypothermia on the durations of postanesthetic care unit and postoperative hospital stays and incidence of complications. RESULTS: Immediate postoperative hypothermia (tympanic membrane temperature < 36.0°C) was more prevalent in the hybrid than in the standard operating room group (20% vs. 36.6%, p = 0.033), with a relative risk of 2.86 (95% confidence interval 1.24-6.64, p < 0.001). Patients undergoing surgery in the hybrid operating room who experienced immediate postoperative hypothermia stayed longer in the postanesthetic care unit (26 min vs. 40 min, p < 0.001) and in the hospital after surgery (4 days; range 3-5 vs. 4 days; range 4-11, p = 0.021). However, the complication rates of both groups were not significantly different (11.3% vs 7.3%, p = 0.743). CONCLUSION: Hybrid operating rooms may increase the risk of postoperative hypothermia. Postoperative hypothermia is associated with prolonged postanesthetic care unit and hospital stays. Preventing hypothermia in patients in hybrid operating rooms is of utmost importance.

OBJECTIVES: We present the original technique of compression hemostatic sutures on the lower uterine segment due to early postpartum hemorrhage during cesarean section, with a literature review. METHODS: A retrospective clinical case study was conducted at the tertiary perinatal center. Twelve patients had nine planned and three urgent cesarean sections due to antenatally verified placenta previa and/or placenta accreta spectrum and defined early postpartum hemorrhage > 1000 mL during cesarean section. As the use of uterotonics failed to produce any effect and hemorrhage persisted, compression sutures of the lower uterine segment were made by our own technique, as follows: below the hysterotomy, a horizontal corrugated suture is placed from the right to the left corner and after 2-3 cm vertically and backwards at several sites from the left to the right corner, where it is tightened. RESULTS: Seven patients had one cesarean section, three patients had two cesarean sections, and seven patients had pregnancy from the in vitro fertilization procedure in their history. There were six patients with placenta previa and six patients with anterior invasive placenta accreta or increta. Original hemostatic procedure was applied successfully in ten cases, and after placement of O'Leary suture and persistent bleeding in two cases. In this group, no hysterectomy was performed, and patients received blood transfusion of 440-880 mL. Three patients later had spontaneous pregnancies. CONCLUSION: Our own hemostatic method with a simple technique, fast learning, and minimal logistics contributes to successful management of this currently global problem of morbidly adherent placenta previa.

BACKGROUND: Placenta accreta spectrum often leads to massive hemorrhage and even maternal shock and death. This study aims to identify whether cervical length and cervical area measured by magnetic resonance imaging correlate with massive hemorrhage in patients with placenta accreta spectrum. METHODS: The study was conducted at our hospital, and 158 placenta previa patients with placenta accreta spectrum underwent preoperative magnetic resonance imaging examination were included. The cervical length and cervical area were measured and evaluated their ability to identify massive hemorrhage in patients with placenta accreta spectrum. RESULTS: The cervical length and area in patients with massive hemorrhage were both significantly smaller than those in patients without massive hemorrhage. The results of multivariate analysis show that cervical length and cervical area were significantly associated with massive hemorrhage. In all patients, a negative linear was found between cervical length and amount of blood loss (r =-0.613), and between cervical area and amount of blood loss (r =-0.629). Combined with cervical length and cervical area, the sensitivity, specificity, and the area under the curve for the predictive massive hemorrhage were 88.618%, 90.209%, and 0.890, respectively. CONCLUSION: The cervical length and area might be used to recognize massive hemorrhage in placenta previa patients with placenta accreta spectrum.

BACKGROUND: The appropriate use of obstetric blood transfusion is crucial for patients with placenta previa and prenatal anemia. This retrospective study aims to explore the correlation between prenatal anemia and blood transfusion-related parameters in this population. METHODS: We retrieved the medical records of consecutive participants who were diagnosed with placenta previa and underwent cesarean section in our hospital. We compared the baseline demographics and clinical characteristics of patients with and without anemia. The correlation between prenatal anemia and obstetric blood transfusion-related parameters was evaluated using multivariate regression analysis. RESULTS: A total of 749 patients were enrolled, with a mean prenatal hemoglobin level of 10.87 ± 1.37 g/dL. Among them, 54.87% (391/749) were diagnosed with anemia. The rate of obstetric blood transfusion was significantly higher in the anemia group (79.54%) compared to the normal group (44.41%). The median allogeneic red blood cell transfusion volume in the anemia group was 4.00 U (IQR 2.00-6.00), while in the normal group, it was 0.00 U (IQR 0.00-4.00). The prenatal hemoglobin levels had a non-linear relationship with intraoperative allogeneic blood transfusion rate, massive blood transfusion rate, red blood cell transfusion units, and fresh plasma transfusion volume in patients with placenta previa, with a threshold of 12 g/dL. CONCLUSIONS: Our findings suggest that prenatal anemia is associated with a higher rate of blood transfusion-related parameters in women with placenta previa when the hemoglobin level is < 12 g/dL. These results highlight the importance of promoting prenatal care in placenta previa patients with a high requirement for blood transfusion.

OBJECTIVES: To compare delivery outcomes of pregnancies diagnosed with placenta-accreta-syndrome (PAS) who underwent conservative treatment to patients who underwent cesarean hysterectomy. METHODS: A retrospective study of all women diagnosed with PAS treated in one tertiary medical center between 03/2011 and 11/2020 was performed. Comparison was made between conservative management during cesarean delivery and cesarean hysterectomy. Conservative management included leaving uterus in situ with/without placenta and with/without myometrial resection. RESULTS: A total of 249 pregnancies (0.25â¯% of all deliveries) were diagnosed with PAS, 208 underwent conservative cesarean delivery and 41 had cesarean hysterectomy, 31 of them were unplanned (75.6â¯%). The median number of previous cesarean deliveries was significantly higher in the cesarean hysterectomy group. There was no difference in the duration from the last cesarean delivery, the presence of placenta previa, pre-operative hemoglobin or platelets levels between the pregnancies with conservative management and the cesarean hysterectomy. Significantly more pregnancies with sonographic suspicion of placenta percreta and bladder invasion had cesarean hysterectomy. Cesarean hysterectomy was significantly associated with earlier delivery, with bleeding and required significantly more blood products. There was no statistically significant difference in the rate of relaparotomy following cesarean delivery or the rate of infections. Multivariable-regression-analysis revealed a significant odds ratio of 3.38 of blood loss of >3,000â¯mL following cesarean hysterectomy. CONCLUSIONS: Conservative management in delivery of PAS pregnancies is associated with less bleeding complications during surgery compared to cesarean hysterectomy.

OBJECTIVES: The objective of study is to describe a new surgical approach to cesarean delivery in women with invasive placenta accreta spectrum (PAS) accompanied by placenta previa. MATERIAL AND METHODS: Cesarean delivery was initiated with a transverse abdominal (Pfannenstiel) incision. A transverse incision was made above the vascular area in the lower uterine segment, and the fetus was delivered. The uterine fundus was removed from the abdomen and wrapped. Placental removal was started at posteriorly, continuing toward the anterior region. If dense adhesions were encountered, dissection was performed by inserting a finger between the adhesions to carefully separate them. It was recognized that two types of vessels develop to supply blood to the placenta. First, a perforating vessel emerges from adjacent tissues, entering the placental bed by perforating the uterine wall. Second, a superficial vessel runs along the uterine wall to enter the placental bed. The new emerging vessels were identified and ligated. Uterine sparing surgery was performed if the hemorrhage ceased. A cesarean hysterectomy was performed if hemorrhage did not cease. RESULTS: Eight cesarean deliveries were performed using this new surgical approach. Cesarean hysterectomy was performed in three patients in who want to sterilization diser and don't mind fertility preservation. Severe maternal morbidity, invasive procedures, intensive care unit admission, and relaparotomy were not required. CONCLUSIONS: The described new surgical approach provide surgeon to perform cesarean delivery without causing increase maternal morbidity and mortality. Although the approach is new and the study population is small, the results have acceptable rationality and applicability.

OBJECTIVE: To explore the change trends in incidence and leading factors to peripartum hysterectomy (PH) at a regional tertiary medical center in northeast China. METHODS: This was a retrospective observational study of all PH cases conducted at Shengjing Hospital between January 1, 2012 and December 31, 2021. Information on maternal characteristics of pregnancy and delivery, indications of PH, inventions before hysterectomy, complications, and maternal and neonatal outcomes obtained from the Shengjing Hospital Information System were analyzed. RESULTS: Among a total of 157 553 deliveries, there were 127 cases of PH (overall PH incidence: 0.85/1000 deliveries); 120 patients (94.49%) underwent hysterectomy after cesarean section, and seven (5.51%) underwent vaginal delivery (P < 0.001). Abnormal placentation was the leading indication for PH (101, 79.53%), including placenta previa (PP) with placenta accreta spectrum (PAS) (93, 73.23%), PP alone (5, 3.94%), and PAS alone (3, 2.36%). Among the patients who underwent PH with abnormal placentation, 92.08% had at least one cesarean section (P < 0.001) and 20.19% had bladder injury (P = 0.044). All maternal deaths (n = 2) occurred in referral patients, and the maternal mortality rate was 1.57/100 hysterectomies. CONCLUSION: Abnormal placentation was the primary indication for PH. For such patients, adequate assessment of their condition and complete communication are strongly recommended. The identification of high-risk groups for postpartum hemorrhage, timely and effective rescue, and referral are equally important for avoiding PH.

OBJECTIVES: To compare maternal outcome measures in surgical management of placenta accreta spectrum (PAS)-the modified one-step conservative uterine surgery (MOSCUS), a new approach at Tu Du Hospital in Vietnam, versus cesarean hysterectomy, and to identify factors that appear to contribute to the successful outcome of the MOSCUS. METHODS: This retrospective study was conducted at Tu Du Hospital in southern Vietnam between January 2019 and December 2020. The study enrolled all pregnant women at more than 28 weeks of pregnancy with a diagnosis of PAS who underwent either a cesarean hysterectomy or a uterus-preserving approach using the MOSCUS method. RESULTS: The prevalence of PAS at our single tertiary referral hospital was 0.4% (619 PAS cases/132 518 births) in 2 years. Among 296 patients, the surgical time duration, estimated blood loss, and red blood cell transfusion in the MOSCUS group (n = 217) were all significantly less than in the cesarean hysterectomy group (n = 79) (152.72 ± 42.23 vs 185.13 ± 58.22 min, 1000 vs 1500 mL, and 500 vs 710 mL, respectively). Intraoperatively, the rate of visceral injuries in the hysterectomy group was higher than that in the MOSCUS group (P < 0.001). However, the rate of postoperative infection was higher in the MOSCUS group than in the cesarean hysterectomy group (P = 0.012). Of a total of 217 cases managed using the MOSCUS management, 24 required a secondary hysterectomy; the success rate was 88.9% (95% confidence interval [CI] 84.3%-93.1%). Some of the primary factors associated with the success of MOSCUS included maternal age less than 35 years, planned surgery, severity of PAS, and estimated blood loss during surgery (odds ratio [OR] 5.16, 95% CI 1.96-13.59; OR 3.05, 95% CI 1.08-8.62; OR 3.62, 95% CI 1.19-10.98; and OR 49.66, 95% CI 11.16-221.02, respectively; P < 0.05). CONCLUSION: MOSCUS is an acceptable alternative to cesarean hysterectomy in many patients diagnosed with PAS. This new surgical management of PAS resulted in the preservation of the uterus, and a favorable outcome in nearly 9 out of 10 pregnant women. We believe that MOSCUS can be safely offered for the management of PAS in referral hospital settings.

INTRODUCTION: The study aims to evaluate and report on the clinical characteristics, incidence, risk factors and associated complications of emergency and planned peripartum hysterectomy in a single training and research tertiary health care centre in Malaysia. MATERIALS AND METHODS: We conducted a 6-year retrospective cross-sectional study from the 1st January 2016 until 31st December 2021. Clinical, demographic characteristics, perioperative parameters, operative indications, blood loss, maternal/neonatal outcomes and complications were analysed. Patients were subdivided, analysed and studied in two subgroups- emergency hysterectomy (EH) and planned hysterectomy (PH). RESULTS: There were 65 cases of peripartum hysterectomy out of total 100,567 deliveries, with a prevalence rate of 0.06%. Overall, the majority of patients were multiparous (96.9%), having previous caesarean scar (73.8%) or diagnosed with placenta praevia (75.4%). More than half of the total patients (61.5%) have both previous caesarean scar and concomitant placenta praevia. EH was carried out in 39(60%) patients while 26(40%) patients underwent PH. The only indication for surgery in the PH group (100%) was abnormal placentation while the most common indication for surgery in the EH group (53.8%) was postpartum haemorrhage related to abnormal placentation. Patients who underwent EH were more likely to have massive blood loss (p=0.001), require ICU admissions (p=0.001), have DIVC cycles transfused (mean [SD] regime: 1.35 [0.95] vs 0.54 [0.99]; p=0.002), have lower postoperative haemoglobin level (mean [standard deviation, SD] haemoglobin: 9.23g/l [SD1.8] vs. 10.8 g/l [SD1.86]; p=0.001) and have higher difference between pre/post operative haemoglobin level (mean [SD] haemoglobin difference: 1.78g/l [SD6.34] vs 0.32g/l [SD1.7]; p=0.008) compared to patients with PH. Red blood cell transfusion, operating time, length of stay, weight of babies and Apgar score between two groups showed no significant differences. A significant reduction of blood loss between the first and the second half duration of the study (mean [SD] blood loss: 6978 ml [SD 4999.45] vs. 4100ml [SD2569.48]; p=0.004) was also observed. In the emergency group, 'non-placental cause' EH required significantly more red blood cell transfusion than 'placental cause' (p<0.05) while in the PH group, no significant difference was observed between the occlusive internal iliac artery 'balloon' and 'no balloon' subgroup in terms of operating time, total blood loss or blood transfusion. Overall complications showed more cases of post operative fever and relaparotomy in the EH group (18.4% vs. 7.6%) while urinary tract injuries including injuries to bladder and ureter occurred only in the PH group (9.4% vs. 0%). CONCLUSION: The majority of peripartum hysterectomy cases are due to placenta accreta spectrum disorders. Planned peripartum hysterectomies have a lower morbidity rate compared to emergency hysterectomies. Therefore, early identification of placenta accreta spectrum disorders and timely planning for elective procedures are crucial to minimise the need for emergency surgery.
