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.展开更多

Study Design: ...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.展开更多

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.展开更多

Some researchers think that the timing of primary cesarean delivery is associated with placenta accreta in subsequent pregnancies. The aim of this study was to investigate the risk of placenta accreta following primary CS without labor, also called primary elective CS, in a pregnancy complicated with placenta previa. Methods: A retrospective, single-center, case-control study was conducted at Peking University Third Hospital. Relevant clinical data of singleton pregnancies between January 2010 and September 2017 were recorded. The case group included women with placenta accreta who had placenta previa and one previous CS. Control group included women with one previous CS that was complicated with placenta previa. Maternal age, body mass index, gestational age, fetal birth weight, gravity, parity, induced abortion, the rate of women received assisted reproductive technology, other uterine surgery, and primary elective CS were analyzed between the two groups. Results: The rate of primary elective CS (90.1% vs. 69.9%, P 〈 0.001 ) was higher, and maternal age was younger (32.7 ± 4.7 years vs. 34.6 ± 4.0 years, P 〈 0.001) in case group, compared with control group. Case group also had higher gravity and induced abortions compared with the control group (both P 〈 0.05). Primary CS without labor was associated with significantly increased risk of placenta accreta in a subsequent pregnancy complicated with placenta previa (odds ratio: 3.32; 95% confidential interval: 1.68-6.58). Conclusion: Women with a primary elective CS without labor have a higher chance of developing an accreta in a subsequent pregnancy that is complicated with placenta previa.展开更多

文摘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.
文摘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.

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.

文摘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.
文摘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.
文摘目的系统评价剖宫产术中不同时机行血管介入阻断对凶险性前置胎盘患者及胎儿的影响。方法采用计算机检索PubMed、Embase、Medline、Web of Science、维普、万方数据库、中国知网、中国生物医学文献数据库等中不同时机行血管介入阻断对凶险性前置胎盘的相关研究。检索时限为建库至2024年3月1日,由两名研究员独立筛选随机对照或回顾性文献、提取数据,选用Review Manager 5.4.1软件分析,参照Cochrane协作网提供的偏倚风险评估工具对文献质量进行评估。结果共纳入12篇目标文献,1030例凶险性前置胎盘患者。Meta分析结果显示,胎儿娩出前阻断可降低术后子宫切除率(OR=0.54,95%CI:0.33~0.89)和术后入住ICU病房率(OR=0.34,95%CI:0.19~0.63),但不能降低序贯子宫动脉栓塞率(OR=0.61,95%CI:0.28~1.32)。此外,对胎儿1 min Apgar评分(MD=0.11,95%CI:-0.23~0.46)、5 min Apgar评分(MD=0.10,95%CI:-0.04~0.24)、1 min Apgar评分≤7分(OR=0.81,95%CI:0.36~1.85)、5 min Apgar评分≤7分(OR=0.93,95%CI:0.33~2.63)无明显影响。结论胎儿娩出前介入阻断的临床价值更高,且不会增加胎儿不良结局。
文摘目的荟萃分析回收式自体输血(IOCS)在前置胎盘剖宫产术中的安全性和有效性。方法计算机检索PubMed、Web of Science、Embase、the Cochrane Library of clinical trials、中国知网(CNKI)及万方数据知识服务平台。检索时限设定为建库至2022年12月。采用R 4.1.2与Stata 12.0软件计算IOCS组和异体输血(ABT)组之间的标准化均数差(SMD)或相对危险度(RR)及95%置信区间(CI)和预测区间(PI)。结果本次Meta分析共纳入5项随机对照试验和10项回顾性队列研究。队列研究的合并结果显示,与ABT组相比,接受IOCS的前置胎盘孕产妇术后血红蛋白(Hb)浓度(SMD=0.626,95%CI:0.103~1.149;95%PI:-1.320~2.572)与红细胞压积较高(SMD=0.617,95%CI:0.130~1.104;95%PI:-1.084~2.317)。在随机对照试验中,接受IOCS的前置胎盘孕产妇发生不良事件的风险比ABT组低72.7%(RR=0.273,95%CI:0.082~0.904)。IOCS组和ABT组术后凝血酶原时间(PT)、活化凝血酶原时间(APTT)、纤维蛋白原(Fib)浓度、血尿素氮(BUN)和肌酐(Cr)差异均无无统计学意义。结论接受IOCS的前置胎盘孕产妇术后Hb浓度和Hct均高于接受ABT的妇女。IOCS对术后凝血参数和肾功能参数无显著影响。在接受剖宫产术的前置胎盘孕产妇中,IOCS与较低的输血相关不良事件发生风险有关。
文摘Background: Cesarean section (CS) is an independent risk factor for placenta accreta. Some researchers think that the timing of primary cesarean delivery is associated with placenta accreta in subsequent pregnancies. The aim of this study was to investigate the risk of placenta accreta following primary CS without labor, also called primary elective CS, in a pregnancy complicated with placenta previa. Methods: A retrospective, single-center, case-control study was conducted at Peking University Third Hospital. Relevant clinical data of singleton pregnancies between January 2010 and September 2017 were recorded. The case group included women with placenta accreta who had placenta previa and one previous CS. Control group included women with one previous CS that was complicated with placenta previa. Maternal age, body mass index, gestational age, fetal birth weight, gravity, parity, induced abortion, the rate of women received assisted reproductive technology, other uterine surgery, and primary elective CS were analyzed between the two groups. Results: The rate of primary elective CS (90.1% vs. 69.9%, P 〈 0.001 ) was higher, and maternal age was younger (32.7 ± 4.7 years vs. 34.6 ± 4.0 years, P 〈 0.001) in case group, compared with control group. Case group also had higher gravity and induced abortions compared with the control group (both P 〈 0.05). Primary CS without labor was associated with significantly increased risk of placenta accreta in a subsequent pregnancy complicated with placenta previa (odds ratio: 3.32; 95% confidential interval: 1.68-6.58). Conclusion: Women with a primary elective CS without labor have a higher chance of developing an accreta in a subsequent pregnancy that is complicated with placenta previa.
文摘目的:探讨髂内动脉球囊预置阻断术在植入型凶险性前置胎盘中的临床价值。方法:选取2021年7月—2024年1月阳江市人民医院收治的60例植入型凶险性前置胎盘患者。根据随机数表法将其分为对照组与观察组,各30例。两组均行剖宫产,对照组应用常规止血措施,观察组应用双侧髂内动脉球囊预置术。比较两组围手术期指标、新生儿情况、子宫切除率、并发症。结果:观察组术中出血量少于对照组,手术时间与住院时间均短于对照组,差异有统计学意义(P<0.05)。两组新生儿出生1 min、5 min、10 min Apgar评分比较,差异无统计学意义(P>0.05)。观察组子宫切除率、并发症发生率均低于对照组,差异有统计学意义(P<0.05)。结论:双侧髂内动脉球囊预置术应用于植入型凶险性前置胎盘患者中效果显著,能够减少产妇术中出血量,降低大出血风险,缩短手术时间和住院时间,降低患者子宫切除率与术后并发症发生率。
