超声检查剖宫产术后子宫瘢痕妊娠的临床价值分析

目的探讨超声在诊断剖宫产术后子宫瘢痕妊娠中的临床价值。方法对剖宫产术后子宫瘢痕妊娠患者27例行阴道超声联合腹部超声检查,其中又以阴道超声检查为主,腹部超声检查为辅,对其临床资料及影像学资料进行回顾性分析。结果本组患者中共有25例患者与临床诊断结果一致,其诊断符合率为(92.59%),超声诊断结果与临床诊断结果对比无明显差异(P0.05)。结论超声在剖宫产术后子宫瘢痕妊娠中具有良好的诊断价值,可有效确定患者的妊娠囊着床部位。     

剖宫产瘢痕部位妊娠病因及诊疗研究进展

剖宫产瘢痕部位妊娠是指于前次剖宫产术后子宫切口瘢痕处发生的妊娠,是一种特殊类型的异位妊娠。近年来,随着剖宫产率的上升,瘢痕部位妊娠发生率也在随之升高。目前,有关剖宫产瘢痕部位妊娠的形成机制尚不明确,多数学者倾向于"窦道形成学说",认为其发生与子宫内膜层和肌层连续被破坏,局部子宫肌层窦道形成有关。另有研究表明,多次剖宫产史、子宫下段厚度及剖宫产缝合技术等因素,也可能影响剖宫产瘢痕部位妊娠的发生。本病诊断主要依靠超声检     

剖宫产术后瘢痕处妊娠的彩色多普勒超声

目的:探讨剖宫产术后子宫瘢痕处妊娠的彩色多普勒超声声像图特征,了解彩色多普勒超声在子宫瘢痕处妊娠诊断、鉴别诊断以及监测治疗效果中的意义.方法:回顾性分析2000年1月～2007年12月我院诊治的13例剖宫产术后瘢痕处妊娠病人的超声图像、治疗及预后情况.结果:剖宫产术后子宫瘢痕处妊娠具有特异的彩色多普勒超声声像图特征,彩色多普勒超声可监测经甲氨蝶呤治疗后瘢痕处妊娠物二维图像及血流信号变化情况.结论:彩色多普勒超声对剖宫产术后子宫瘢痕处妊娠的早期诊断具有重要意义,而早期诊断和及时治疗能减少或避免大出血的发生,并可有效地监测治疗效果.     

经阴道彩色多普勒超声对剖宫产切口瘢痕妊娠的诊断价值

剖宫产切口瘢痕妊娠是一种少见特殊类型的异位妊娠,是孕囊着床于子宫下段剖宫产瘢痕处的异位妊娠。随着剖宫产率的升高,发病率有所提高,对子宫瘢痕妊娠（cesarean searpregnancy,CSP）的报道也逐渐增多。剖宫产切口瘢痕妊娠处理不当,容易发生难以控制的大出血。对该病的早期诊断是决定预后的关键。本文就超声诊断剖宫产切口子宫瘢痕妊娠进行分析,探讨其诊断价值。     

剖宫产瘢痕部位妊娠误诊1例

剖宫产瘢痕部位妊娠（ CSP ）是指有剖宫产史的孕妇,胚胎着床于子宫下段剖宫产切口瘢痕处,是一种特殊部位的异位妊娠,为剖宫产的远期并发症之一［1］。但由于本病的早期诊断困难,初诊误诊率高,而且瘢痕处肌壁薄弱且纤维组织多,若处理不及时或不恰当,易导致难以控制的阴道大出血或子宫破裂,危及患者生命。将收治的1例剖宫产瘢痕部位妊娠的诊治经过及误诊原因分析如下。     

彩色多普勒超声在剖宫产后子宫瘢痕处妊娠诊断与治疗中的价值

<正> 剖宫产术后子宫瘢痕妊娠(caesarean scarpregnancy,CSP)是指孕卵着床于剖宫产后子宫瘢痕部位并在此生长发育,被归属于异位妊娠,是剖宫产术后的远期并发症之一,以往临床少见,但随着剖宫产率的逐年提高而呈上升趋势。如果不及时诊断和正确处理,将有子宫破裂和大出血,甚至切除子宫的可能。早在1997年,Codin等就首次描述了剖宫产术后子宫瘢痕妊娠时超声检查的诊断标准。此后国内很多学者也相继报道了彩色多普勒超声(color Doppler flow imaging,CDFI)在早期诊断CSP中的重要作用。本文通过查阅近年来文献,回顾分析CSP患者CDFI的声像图及血流频谱     

阴式超声在剖宫产瘢痕处妊娠检查中的临床应用

剖宫产术后子宫瘢痕处妊娠是一种特殊类型的宫内异位妊娠,临床上比较少见,近年来其发病率随着剖宫产术的不断增加而上升。对剖宫产术后子宫瘢痕处妊娠的早期诊断,选择治疗的方法及对保守治疗疗效的评价已越来越受到妇产科医生的重视。本文总结2004年10月～2008年12月收治我院妇产科住院的子宫瘢痕处妊娠7例患者进行回顾性分析,旨在探讨彩色多普勒超声在剖宫产子宫瘢痕处妊娠检查中的临床应用价值。     

彩色多普勒超声在子宫瘢痕妊娠诊断中的临床价值

目的：探讨彩色多普勒超声在子宫瘢痕妊娠诊断中的价值。方法选择妇产科收治的剖宫产手术后子宫瘢痕妊娠患者31例,所有患者均行经腹彩色多普勒超声以及经阴道彩色多普勒超声,分析总结子宫瘢痕妊娠的超声声像图特点。结果按声像图表现分为孕囊型10例,混合性包块型18例及部分位宫腔型3例,其中血流信号丰富者25例,少血流信号者6例。结论子宫瘢痕妊娠有特征性超声表现,彩色多普勒超声能根据其特征性超声表现做出较准确的定位及定性诊断,对治疗方案的制定,疗效评估有重要的指导意义。     

剖宫产瘢痕妊娠超声早期诊断价值

目的：分析剖宫产瘢痕妊娠超声早期诊断价值。方法分析诊治的42例剖宫产瘢痕妊娠患者临床资料,所有患者分别进行超声检查,并将检查结果与手术、病理检查结果进行比较分析。结果超声早期诊断剖宫产瘢痕妊娠患者40例,准确率为95．23％;超声早期诊断与手术病理结果对比,差异无统计学意义（ P＞0．05）。结论临床采用彩色多普勒超声诊断早期剖宫产瘢痕妊娠超准确率较高,并且对患处无创伤,重复性高,是临床早期诊断剖宫产瘢痕妊娠的常规手段。     

剖宫产术后子宫瘢痕处早期妊娠的超声图像分析

目的:探讨剖宫产术后子宫瘢痕处早期妊娠的超声图像特征。材料和方法:对7例剖宫产术后子宫瘢痕处早期妊娠超声图像进行回顾性分析。结果:剖宫产术后子宫瘢痕处早期妊娠的超声图像表现为子宫下段前壁向外凸出,其内可见包块影像,包块与膀胱之间子宫肌层变薄。包块回声大致分混合回声包块和囊性包块两种类型:前者其内及其周围血运丰富,后者部分囊内可见胎芽组织。结论:剖宫产术后子宫瘢痕处早期妊娠的超声图像比较有特异性,可为对该病的诊断提供有价值的信息。     

Optimization of the system of medical service of students of Cadet Schools of the Ministry of Defense of the Russian Federation

One of the factors of the successful military career guidance Cadet schools students is preserving and promoting their health. Medical support of children and adolescents aged 10-17 years should include the full range of medical and preventive measures defined for this group. The state of providing outpatient care for pupils at the Cadet School in St. Petersburg was studied. These results show that full medical care in accordance with the standards can be based only on children's health clinics. It is important that the organization of medical support pupils cadet schools should be cooperate with civilian health care.

Estimation of accumulated dose of radiation by method of ESR-spectrometry of dental enamel of mammals

ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P_1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. ‘Dose-response’ dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of ‘radiosensitivity’ enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method.     

Analysis of the results of the international comparison of activity measurements of a solution of Fe

The results of an international comparison of activity measurements of a solution of ⁵⁵Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a ⁵⁵Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.

The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison.     

Evaluation of the results of various technics of non-surgical therapy of varicocele

A new method of non-surgical treatment of varicocele syndrome is described: it consists in sclerotherapy of spermatic vein by trans-femoral percutaneous catheterization with balloon-catheters. In 8 cases venous thrombosis has been induced by direct electric clotting. The techniques and a 6 months follow-up are discussed. It is pointed out that this procedure should be considered as the method of choice for tubular lesions and sub-fertility prophylaxis in young people and in childhood.
