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.

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 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 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.

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.

Comparison of cell salvage with one and two suction devices during cesarean section in patients with placenta previa and/or accrete: a randomized controlled trial

Background:Cell salvage has recently been recommended for obstetric use in cases with a high risk of massive hemorrhage during cesarean section(CS).However,limited data are available to support the use of one suction device to collect lost blood.This study aimed to investigate the volume of red blood cells(RBCs)salvaged and the components of amniotic fluid(AF)in blood salvaged by one suction device or two devices during CS in patients with placenta previa and/or accrete.Methods:Thirty patients with placenta previa and/or accrete undergoing elective CS in the Women's Hospital of Zhejiang University School of Medicine were recruited for the present study from November 1,2017 to December 1,2018.The patients were randomly assigned to one of the two groups according to an Excel-generated random number sheet:Group 1(w=15),in which only one suction device was used to aspirate all blood and AF,and Group 2(w=15),in which a second suction device was mainly used to aspirate AF before the delivery of the placenta.Three samples of blood per patient(pre-wash,post-wash,and post-filtration)were collected to measure AF components.The salvaged RBC volumes were recorded.Continuous data of pre-wash,post-wash,and postfiltration samples were analyzed by using one-way analysis of variance with Tukey5s test for multiple comparisons,or Kruskal-Wallis test with Dunn test for multiple comparisons.Comparisons of continuous data between Group 1 and Group 2 were conducted using Student's t test or Mann-Whitney U test.Results:The salvaged RBC volume was significantly higher in Group 1 than that in Group 2(401.6±77.2 mL vs.330.1土53.3 mL,?=4.175,P<0.001).In both groups,squamous cells,lamellar bodies,and fat were significantly reduced by washing(all P<0.001)and squamous cells were further reduced by filtering(P<0.001).Squamous cells were found in six post-filtration samples(three from each group).Lamellar bodies and fat were completely removed by filtering.Insulin-like growth factor binding protein 1,alphafetoprotein,albumin,lactate dehydrogenase,and potassium were significantly reduced post-wash(all P<0.05),with no further significant reduction after filtration in either group(all P>0.05).The mean percentage of fetal RBCs post-filtration was(1.8±0.8)%with a range of 1.0%to 3.5%and(1.9±0.9)%with a range of 0.7%to 4.0%in Groups 1 and 2,respectively,showing no significant difference between the two groups(U=188.5,P=0.651).Conclusion:Cell salvage performed by one suction device could result in higher volume of salvaged RBCs and can be used safely for CS in patients with placenta previa and/or accrete when massive hemorrhage occurs.Trial registration number:ChiCTR-INR-17012926,http://www.chictr.org.cn/Chinese Clinical Trial Registry.

目的探讨凶险性前置胎盘与新生儿窒息相关的超声检查、高危因素及妊娠结局。方法回顾性分析2016年5月~2020年7月华中科技大学同济医学院附属同济医院收治的144例凶险性前置胎盘孕产妇的临床资料,根据新生儿情况分为未窒息组(n=91)和窒息组(n=53)。主要通过产前超声检查、术中诊断等方法,采用单因素及多因素Logistic回归分析新生儿窒息的高危因素,并比较两组新生儿的结局。结果与未窒息组比较,窒息组前壁胎盘为主、完全性前置胎盘、早产、羊水过多、胎盘穿透的发生率更高,差异均有统计学意义(P<0.05)。多因素Logistic回归分析结果显示,前壁胎盘为主、早产、羊水过多、胎盘穿透是新生儿窒息的的独立危险因素(P<0.05,OR>1)。与未窒息组比较,窒息组出生孕周及出生体重更低,入住新生儿科的发生率更高(P<0.05)。结论凶险性前置胎盘与新生儿窒息相关的高危因素为前壁胎盘为主、早产、羊水过多、胎盘穿透。凶险性前置胎盘与新生儿窒息相关的妊娠结局更差。
