Balloon displacement during caesarean section with pernicious placenta previa: A case report

BACKGROUND For the past few years,preventive interventional therapy has been widely used domestically and overseas,bringing great benefits to pregnant women at high-risk for complications,such as pernicious placenta previa(PPP)and placenta accreta.Nevertheless,there are still few reports on surgical complications related to interventional therapy,and its safety should be a concern.CASE SUMMARY We report a 36-year-old pregnant woman with PPP who underwent balloon implantation in the lower segment of the abdominal aorta before caesarean section.However,the balloon shifted during the operation,which damaged the arterial vessels after filling,resulting in severe postpartum haemorrhage in the patient.Fortunately,after emergency interventional stent implantation,the pa-tient was successfully relieved of the massive haemorrhage crisis.CONCLUSION It seems that massive postoperative bleeding has been largely avoided in preventive interventional therapy in high-risk pregnant women with placenta-related diseases,but surgical complications related to intervention therapy can also cause adverse consequences.It is equally important for clinical doctors to learn how to promptly identify and effectively treat these rare complications.

Risk Factors and Pregnancy Outcomes： Complete versus Incomplete Placenta Previa in Mid-pregnancy

This prospective study was conducted to compare risk factors and pregnancy outcomes between women with complete placenta previa and those with incomplete placenta previa diagnosed in mid-pregnancy. The study was carried out from April 2014 to December 2015, during which 70 patients with complete previa and 113 with incomplete previa between 20＋0 weeks and 25＋6 weeks of gestation were included. Maternal demographics and pregnancy outcomes were compared between the two groups. Comparisons between categorical variables were tested by chi-squared test and those between continuous variables by Student t test. Resolution ofprevia occurred in 87.43% of the studied women. The mean gestational age at resolution was 32.1＋4.4 weeks. Incidence of maternal age ≥35 years and incidence of prior uterine operation 〉3 were high in women with complete previa （28.6% vs. 8.8%, P=0.003; 28.6% vs. 8.8%, P=0.003）. Resolution ofprevia occurred less often in complete previa group （74.3% vs. 95.6%, P=0.001）. Women with complete previa admitted earlier （37.3±2.0 weeks vs. 38.1±1.4 weeks, P=0.011） and delivered earlier （37.7±1.2 weeks vs. 38.3±1.4 weeks, P=0.025）. Maternal age ≥35 years and prior uterine operation 〉3 increase the risk of complete previa in mid-pregnancy. Placenta previa is more likely to persist in women with complete previa than those with incomplete previa diagnosed in mid- pregnancy. What is more, women with complete previa in mid-pregnancy delivers earlier.

Relationship between Placenta Location and Resolution of Second Trimester Placenta Previa

This prospective study was conducted to assess the rate of resolution of second trimester placenta previa in women with anterior placenta and posterior placenta, and that in women with and without previous cesarean section. In this study, placenta previa was defined as a placenta lying within 20 mm of the internal cervical os or overlapping it. We recruited 183 women diagnosed with previa between 20+0 weeks and 25+6 weeks. They were grouped according to their placenta location(anterior or posterior) and history of cesarean section. Comparative analysis was performed on demographic data, resolution rate of previa and pregnancy outcomes between anterior group and posterior group, and on those between cesarean section group and non-cesarean section group. Women with an anterior placenta tended to be advanced in parity(P=0.040) and have increased number of dilatation and curettage(P=0.044). The women in cesarean section group were significantly older(P=0.000) and had more parity(P=0.000), gravidity(P=0.000), and dilatation and curettage(P=0.048) than in non-cesarean section group. Resolution of previa at delivery occurred in 87.43% women in this study. Women with a posterior placenta had a higher rate of resolution(P=0.030), while history of cesarean section made no difference. Gestational age at resolution was earlier in posterior group(P=0.002) and non-cesarean section group(P=0.008) than in anterior group and cesarean section group correspondingly. Placenta location and prior cesarean section did not influence obstetric outcomes and neonatal outcomes. This study indicates that it is more likely to have subsequent resolution of the previa when the placenta is posteriorly located for women who are diagnosed with placenta previa in the second trimester.

Evaluation of “J”-shaped Uterine Incision during Caesarean Section in Patients with Placenta Previa:A Retrospective Study

This study evaluated the efficacy and safety of ＂J＂-shaped uterine incision for caesarean section for patients diagnosed with placenta previa. A total of 55 consecutive cases of placenta previa treated in Union Hospital were retrospectively analyzed over a period of two years and 10 months. The subjects were divided into two groups with respect to the uterine incision. Twenty-four pregnant women with placenta previa who were indicated for caesarean section underwent the procedure using a new ＂J＂-shaped uterine incision and 31 pregnant women with placenta previa received caesarean section that used the traditional transverse incision. The two groups were compared in terms of operation time, estimated blood loss, infant expulsion time, exhaust time and postoperative recovery. Meanwhile, comparison was also made in neonatal clinical data between the two groups. Compared with the ＂J＂-shaped incision group, the traditional incision group had a lower Apgar scores （P〈0.05）. However, there existed no statistically significant differences in the overall time of operation and postoperative period of breaking wind （P〉0.05）. It is concluded that, with caesarean section for placenta previa patients, the ＂J＂-shaped uterine incision significantly decreases intraoperative blood loss and facilitates the fetal delivery.

Long-term follow-up of abdominal aortic balloon occlusion for the treatment of pernicious placenta previa with placenta accreta

Objective:To evaluate the efficacy and safety of balloon occlusion of the abdominal aorta for the treatment of pernicious placenta previa with placenta accreta.Methods:The clinical data of 623 patients with pernicious placenta previa combined with placenta accrete,who were admitted to our hospital from January 2013 to January 2019 were retrospectively analyzed.All patients underwent abdominal aortic balloon occlusion combined with cesarean section,and 78 patients underwent sequential bilateral uterine artery embolization.We analyzed the operation time,intraoperative blood loss,blood transfusion volume,intraoperative and postoperative complications,fetal radiation exposure time and dose,and the Apgar score of the newborns.We also performed other evaluations to ascertain the efficacy and safety of abdominal aortic balloon occlusion treatment for dangerous placenta previa with placenta accrete.Results:Of the 623 patients,545 underwent only abdominal aortic balloon occlusion,and 78 underwent uterine artery embolization due to intraoperative or postoperative bleeding.The uterus was successfully preserved in all patients.Except for five cases of right lower extremity arterial thrombosis,the remaining patients did not have postoperative lower extremity arteriovenous thrombosis,renal insufficiency,late postpartum hemorrhage,ectopic embolism,spinal cord or peripheral nerve damage,pelvic infection,or other serious complications.The mean operative time was 65.3(±14.5)min.The mean intraoperative blood loss was620(±570)ml.Ninety-six patients(15.4%,96/623)were treated with blood transfusion,and the average amount of blood transfused was 750(±400)ml.The average number of hospitalization days was 6.8(±3.4)days,the average time of fetal ray exposure was 5.2(±1.6)s,and the average radiation dose was 4.1(±2.7)m Gy.The neonatal Apgar score,was 8.4(±0.6)points at 1 min,and 9.6(±0.4)points at 5 min.In the follow-up to May 31,2019,29 patients were lost to follow-up,96 were lactating,and 498 were menstruating.Except for the cases lost to follow-up,the remaining 596 surviving newborns(including 2 twins)showed no abnormalities at the 42-day postnatal outpatient follow-up examination.Conclusion:Balloon occlusion of the abdominal aorta is a safe and effective method for the treatment of pernicious placenta previa with placenta accreta.

Application of ultrasound-guided balloon occlusion in cesarean section in 130 cases of sinister placenta previa

Objective:To investigate the clinical utility of ultrasound-guided balloon occlusion in cesarean section in patients with sinister placenta previa.Methods:The Interventional and Ultrasound Departments of the authors’center assisted obstetrics to complete cesarean section in cases of sinister placenta previa.A total of 130 patients with implanted sinister placenta previa were diagnosed using obstetrical ultrasound and magnetic resonance imaging(MRI).Before cesarean section,the balloon was positioned in the bilateral radial or abdominal aorta.Immediately after delivery of the fetus,the balloon was temporarily filled to transiently seal the target vessel.According to the obstetrician’s assessment of hemostasis,the balloon was withdrawn at the appropriate time.Among the 130 patients,there was one case of abdominal aortic occlusion,with 129 cases blocked by the bilateral common iliac artery.Results:All 130 cases were successfully blocked,with an average blocking time of<15 min,while intraoperative blood loss was 800–1500 ml.Conclusion:Ultrasound-guided balloon blocking treatment before cesarean section can mitigate the dangers of placenta previa and significantly reduce blood loss with no exposure to X-ray radiation.Thus,the technique merits serious consideration.

A Different Method in the Treatment of Placenta Previa:A Comparison of Lower Uterine Segment Transverse Suture Technique and Bakri Balloon Application

Objective: The incidence of placenta previa (PP) has been increasing due to the rise in cesarean rates. The aim of this study is to determine the success of lower uterine segment compression suture and bakri balloon applications in patients diagnosed with placenta previa. Materials and Methods: 257 patients who underwent cesarean section due to placenta previa totalis (PPT) between the years of 2010-2018 in Ondokuz Mayis University were screened retrospectively. The patients were evaluated in four groups according to their treatment method: medical treatment, bakri balloon application, compression suture and hysterectomy. Results: In the study, between the years 2010-2015, postpartum hysterectomy was performed in the cases of adherent placenta previa, and hysterectomy was performed in 33 patients. Between the years of 2015-2018, first, bakri balloon or compression suture was applied;and if bleeding control was not achieved despite these, then, hysterectomy was performed. Between 2015 and 2018, a total of 27 patients underwent compression suture and 1 patient had a hysterectomy after all. The success rate was 96.3% with compression suture and 91.7% for bakri balloon application. Totally, 24 patients were treated with bakri balloon and yet, two patients underwent hysterectomy. When all the cases were examined, complications caused by urinary bladder and ureteral injury were seen in 5.6% of patients, and all of these complications were also seen in hysterectomy patients. Conclusion: Lower uterine segment transverse suture technique and bakri balloon application should be considered as a good alternative to prevent hysterectomy in patients with placenta previa totalis. In addition, they are effective treatment methods that can be used without increasing maternal morbidity.

Placenta Previa at Souro Sanou Teaching Hospital, Burkina Faso (About 142 Cases)

Introduction: Placenta previa is an obstetric emergency that can be life-threatening for both mother and foetus. Despite the progress made in diagnosis and treatment, it continues to be feared by obstetricians because of high maternal and perinatal mortality and increased morbidity. This study aims to investigate the diagnostic, therapeutic and prognostic aspects of placenta previa at the Sourô Sanou University Hospital in Bobo-Dioulasso. Method: This was a descriptive cross-sectional study with retrospective data collection from January 1, 2016 to December 31, 2018. Included were 142 pregnant women admitted to the maternity ward of the Sourô Sanou University Hospital (CHUSS) and diagnosed with placenta previa during pregnancy, labor, or in the postpartum period. Result: The frequency of placenta previa was 0.89%;the average age of patients was 28.51 years with extremes of 16 and 44 years. The multigestations represented 28.17% and the pauciparous 31.69%. Patients with a uterine scar represented 15.49%. Ultrasound diagnosis was made in 38 patients (26.76%). Placenta previa was recovered in 56.34% of cases. Patients with severe anaemia were 28.87%, and 57.04% of the anaemic cases received blood transfusion. Caesarean section was performed in 93.66% of patients. Four maternal deaths (2.81%) and 30 stillbirths (27.02%) were reported. Conclusion: Placenta previa remains a fairly frequent pathology with a non-negligible lethality rate and perinatal mortality in the maternity ward of the Sourô Sanou University Hospital.

Clinical Analysis of Placenta Previa Complicated with Previous Caesarean Section

Objective To investigate the clinical features and treatment of placenta previa complicated with previous caesarean section. Methods The clinical data of 29 patients with placenta previa complicated with a previous caesarean section (RCS group) admitted in Peking Union Medical College Hospital during a period from 2003 to 2011 were retrospectively reviewed and compared with those of 243 patients with placenta previa without a previous caesarean section (FCS group) during the same period. Results There was no difference in the mean age (28.9±3.6 vs. 28.1±4.5 years) and the average gravidity (2.35±1.48 vs. 2.21±1.53) between RCS group and FCS group (all P>0.05). The RCS group had more preterm births (24.1% vs. 13.2%), complete placenta previa (55.2% vs. 4.9%), placenta accreta (34.5% vs. 2.5%), more blood loss during caesarean section (1412±602 vs. 648±265 mL), blood transfusion (51.7% vs. 4.9%), disseminated intravascular coagulation (13.8% vs. 2.1%), and obstetric hysterectomy (13.8% vs. 0.8%) than the FCS group (all P<0.05). The preterm infant rate (30.0% vs. 13.0%), neonatal asphyxia rate (10.0% vs. 4.9%), and perinatal mortality rate (6.7% vs. 0.4%) of the RCS group were higher than those of the FCS group (all P<0.05). Conclusions More patients had complete placenta previa and placenta accreta, postpartum hemorrhage, transfusion, uterine packing, obstetric hysterectomy, and perinatal morbidity in the placenta previa patients with previous caesarean section. The patient should be informed of the risk and unnecessary first cesarean sections should be avoided.

Application of abdominal aortic balloon occlusion followed by uterine artery embolization for the treatment of pernicious placenta previa complicated with placenta accreta during cesarean section

Objective:This study aimed to investigate the clinical effects of abdominal aortic balloon occlusion followed by uterine artery embolization for the treatment of pernicious placenta previa complicated with placenta accreta during cesarean section.Methods:We performed a retrospective analysis of the clinical data for 623 patients who experienced pernicious placenta previa complicated with placenta accreta and received treatment in our hospital from January 2013 to January 2019.All patients underwent abdominal aortic balloon occlusion before their cesarean section.Seventyeight patients received bilateral uterine artery embolization,and among them,placenta accreta was found at the opening of the cervix in 13 patients.Due to suturing difficulty after the removal of the placenta,gauze packing was used to temporarily compress the hemorrhage.As soon as the uterus was sutured,emergent bilateral uterine artery embolization was performed.Active bleeding was noted in the remaining 65 patients when the lower part of the uterus was pressed after the placenta was removed and the uterus was sutured,therefor,bilateral uterine artery embolization was performed urgently.Results:Of the 623 patients,545 patients underwent only abdominal aortic balloon occlusion and 78 patients underwent additional emergent bilateral uterine artery embolization due to hemorrhaging during or after their cesarean section.No hysterectomies were performed.In the 78 patients,the amount of bleeding was 800-3,200 ml with an average of 1,650 ml during the operation;the volume of blood transfused was 360-1,750 ml(average:960 ml).The fetal fluoroscopy time was 3–8 s(average:5 s).The dose of radiation exposure was(4.2±2.9) m Gy.Fetal appearance,pulse,grimace,activity,and respiration(Apgar) score were normal.No serious complications were observed during or after the operation in the follow-up visits.Conclusion:For patients with pernicious placenta previa complicated with placenta accreta who experience active bleeding after cesarean section and abdominal aortic balloon occlusion,bilateral uterine artery embolization can effectively reduce blood loss and requirement of blood transfusion during the operation,and lowers the risk of hysterectomy.

Clinical analysis of 322 cases of placenta previa

In recent years, the incidence of placenta previa has been increasing. According to the literature, it is mainly related to induced labor, artificial abortion, cesarean section, high aging pregnancy, multipara or smoking. The placenta previa is the chief cause of bleeding in late pregnancy and threatens the lives of mother and infant, resulting in a high risk problem in obstetrics. This article studies 322 cases of placenta previa from my hospital and Dalian Obstetrics and Gynecological Hospital from January, 2002 to July, 2009, on the basis of clinicretrospective analysis, in order to deepen our understanding and art of treating placenta previa. The study revealed that: 1. With 322 cases of placenta previa, the incidence was 0.73%. It was higher than the incidence 0.3% reported abroad and lower than the incidence 0.94% reported in our country. The data were from sampling survey and did not prove relations between placenta previa and ages, different from the result obtained abroad in which placenta previa had relation with pregnancy ages. The outcome needs further study. But artificial abortion, induced labor, cesarean section and multipara clearly influence the incidence. The study did not analyze the relation between smoking and placenta previa, but there was external data proving that smoking was related to placenta previa; 2. Ultrasound-B is a better method for examination at present; 3. In cases of vaginal childbirth there was a higher incidence of lateral placenta previa and partial placenta previa. The conservative temporization and timely cesarean section can greatly decrease the mortality of mother and infant.

Clinical Analysis on the Effectiveness of Conservative Compression Suture Technique to Conserve Fertility on Pernicious Placenta Previa

Objective: To evaluate the effectiveness of conservative compression surgical suture techniques used for the management of pernicious placenta previa to conserve fertility in the subsequent pregnancies. Study Design: This was a non-comparative retrospective study of 188 patients diagnosed with pernicious placenta previa who underwent cesarean section in The First Hospital of Jilin University, China, from 1 January 2013 to 1 January 2018. Successful group was defined as those in which the intraoperative bleeding was managed by either modified CHO or by B-lynch suture technique and those who had further intervention including hysterectomy were designated as failure group. Results: Out of 217 patients, 188 met inclusion criteria and 29 patients were excluded. In 188 cases, 183 (97.34%) cases successes and 5 (2.65%) cases had hysterectomy. Among included group, 118 patients (62.76%) had undergone emergency cesarean section and 70 patients (37.23%) underwent elective cesarean section. The emergency group had significantly lesser gestation period of gestation at the time of cesarean section (P = 0.021) and lower neonatal weight (P = 0.001) than that of elective group. The estimated blood loss during surgery was 500 - 3200 ml (mean: 925 ml). Additionally, the amount of bleeding was found to be significantly more in patient with intraoperative complication (P = 0.007) and in patient with implanted placenta (P 0.001). Conclusion: The conservative compression suture technique including modified CHO and B-lynch suture technique during the cesarean delivery is a feasible, safe and effective alternative conservative surgical technique for the management of bleeding in case of pernicious placenta previa. Besides good surgical outcome and proper neonatal result this technique also reduces the rate of hysterectomy, thus conserving the fertility.

Detecting Accuracy of Three Dimensional Power Doppler (3DPD) Vascular Indices for Prenatal Diagnosis of Morbidly Adherent Placenta in Patients with Placenta Previa

Objective:?The study’s objective was to assess the accuracy of using prenatal 3-dimensional power Doppler analysis of vascular placental indices to accurately diagnose morbidly adherent placenta objectively. Background:?Traditionally, 2D ultrasound was used for the diagnosis of a suspected morbidly adherent placenta (MAP) previa. More objective techniques like 3D power Doppler haven’t been well studied. Study Design:?A prospective cohort study?is?designed for women with gestational age between 28 and?32 weeks with suspected placenta previa. Patients were examined by 2D ultrasound which was used in management decisions.?3D Power Doppler’s VI, FI and VFI were measured during the same examination after manual tracing of placenta;data were blinded to obstetricians. Histopathology was performed to confirm MAP. Results: Our results showed that the 3D power Doppler VI ≥ 16 predicted the diagnosis of MAP with 100% sensitivity, 100% specificity which is better than those of 2D ultrasound. While VI > 33.1 measured by 3D Doppler predicted severe MAP with a sensitivity of 73.9% and specificity of 86.4%, which was superior to 2D ultrasound. Conclusion:?In patients with placenta previa, the 3D Doppler’s vascular index accurately predicts MAP. Furthermore, vascular and vascular flow indices of 3D Doppler were more predictive of severe cases of MAP compared to 2D ultrasound.

Maternal Outcome of Cases of Placenta Previa with and without Morbidly Adherent Placenta at King Abdul-Aziz University Hospital, Saudi Arabia

Introduction:?Worldwide increasing cesarean section rates are expected to have a parallel increase in the number of cases of Placenta Previa with all the expected complications, including pathologically adherent placenta. This morbidly adherent placenta constitutes a serious and possibly a life threatening complication. An efficient team capable for managing possible complicated situations will be able to reduce mortality and morbidity. Objectives: The aim of our study was to evaluate maternal outcome in cases of Placenta Previa with and without morbidly adherent placenta. Methods: Analysis of all pregnancies complicated by antepartum hemorrhage during the period from January 2013 to September 2017 at King Abdul-Aziz University Hospital (KAUH), Jeddah, Kingdom of Saudi Arabia (KSA) was done. Cases of Placenta Previa with gestational age > 28 weeks were included. They were classified into 2 groups;Group (A) included Placenta Previa cases without morbidly adherent placenta and Group (B) included cases with morbidly adherent placenta. Maternal outcomes were recorded. Results: Placenta Previa was the leading cause of antepartum hemorrhage constituting 76.8%, out of them 52% were unbooked. Morbidly adherent placenta constituted 13.5% of total Placenta Previa cases and was diagnosed prenatally in only 1 case. Morbidity rate in placenta previa patients with adherent placenta (Group B) was higher than in placenta previa without adherent placenta (Group A). We considered the occurrence of intrapartum hypovolemic shock, Intensive care unit admission, surgical complications and peripartum hysterectomy as parameters for morbidity. P value for hypovolemic shock was insignificant (P = 0.580), significant for Intensive care unit admission (P = 0.008), significant for surgical complications (P = 0.009) and significant for peripartum

Frequency of Placenta Previa and Maternal Morbidity Associated with Previous Cesarean Delivery

Background: Placenta previa (P.P) is a rare pregnancy complication where a placenta particularly or completely covers the internal cervical os thereby preventing normal vaginal delivery. This study was conducted to evaluate the relationship between repeated cesarean deliveries and subsequent development of placenta previa. Methods & Materials: This cross-sectional study was held in Imam Reza Hospital Kermanshah-Iran during 2008-2011. This study included all pregnant women with repeated cesarean sections while nullipara and patients with placenta previa without previous surgery were excluded. Diagnosis was made on ultrasound and at surgery. Results: among 2696 Women, 98 cases had P.P (3.63%). The mean age was 30 years, 76.5% (75 cases) had gravidity 2 and 3 and 87.8% (86 cases) had parity 1 - 3. Anterior location of placenta was 44.9% while posterior was 55.1%. 48% were complete P.P, 32.7% low lying P.P, 13.3% marginal P.P, and 6% Partial P.P. 26.5% of patients had history of abortion. 55.1% of patients had male fetus. There was an increase in frequency of placenta previa with just one previous C-section (74.5%). Frequency of accreta P.P 32% (n = 7), increta (14.3%, n = 3) and percreta 28% (n = 6). Among those who underwent emergency hysterectomy (21 cases) 23.8% cases had no abnormal placentation. 30.6% of newborns had birth weight < 2500 g. Conclusion: we concluded that patients with history of one pervious cesarean delivery had more Placenta previa and need to hysterectomy were more than those with history of 2 and 3 previous cesarean delivery. The most common type of abnormal placentation was accreta, percreta and increta respectively.

Application of Modified Cesarean Hysterectomy for Patients with Placenta Previa Complicated with Placenta Percreta

Objective::To evaluate the efficacy and safety of a modified cesarean hysterectomy(MCH)procedure in controlling hemorrhage in patients with placenta previa complicated with placenta percreta.Methods::A retrospective analysis was conducted on 23 patients with placenta previa complicated with placenta percreta from January 2016 to December 2018 in the Union Hospital.The patients’age ranged from 24 to 41 years,and had gestational durations of 32-38 weeks.Nine of them underwent MCH and 14 underwent conventional cesarean hysterectomy(CCH).In the MCH group,the bladder was not mobilized,deliberately.The uterus was excised horizontally above the tourniquet level.Placental tissue around the cervical os was cleaned thoroughly,and hemostatic suturing was performed under direct vision.In the CCH group,the uterus was removed gradually after programmed hemostasis and dissection of adhesions of the vesicouterine peritoneal fold and mobilization of the bladder.Results::There were no significant differences in general conditions between the two groups.The blood loss was significantly less in the MCH group(P<0.05).The operation time was also decreased dramatically and hospital stay(in days)was shorter than in the CCH group(P<0.05).There were no bladder or ureter injuries in the MCH group,compared with three cases in the CCH group.There were no statistically significant differences in neonatal birth weight,Apgar score,or intensive care unit admittance rates between the two groups(P>0.05).Conclusion::This MCH procedure reduced blood loss,avoided bladder injury,and had no long-term complications.It is a safe,rapid,and effective way to control fatal hemorrhage during surgery for women with placenta previa complicated with placenta percreta.

Precision Surgery for Placenta Previa Complicated with Placenta Percreta

Objectives:To investigate whether a precise circular resection of the uterine tissue at the placental attachment part is effective in cases with placenta previa complicated with placenta percreta (PPWPP).Methods:Patients diagnosed with PPWPP were assessed for pregnancy termination at 34-36 weeks of gestation.During the operation,we performed circular resection of the uterine tissue at the placental attachment part.Then the characteristics of the operation and the follow-ups were recorded.Results:During the operation,the vital signs were stable.The mean intraoperative blood loss,packed red blood cells units transfusion,fresh frozen plasma transfusion,and operation time were 2140 mL,6 U,440 mL,and 179.8 minutes,respectively.There was no bowel,ureter,or bladder injury.And there was no patient transferred to the ICU after operation.The mean postoperative blood loss was 458.6mL.There was no fever,infection,intestinal obstruction,or other complications after operation during the hospitalization.The shape and the blood flow of the uterus were normal.After the patients were discharged,one had developed cesarean scar diverticulum.The mean lochia duration was 30 days.The menstrual cycle and volume were as before.The shape and the blood flow of the uterus and the ovarian were normal.Conclusions:The circular resection following end-to-end anastomosis is an effective precision surgical approach for PPWPP.It can achieve the purpose of hemostasis while maximizing the protection of organ function and reducing surgical trauma.
