The treatment and prognosis of cervical cancer depends on the clinical stage based on the FIGO classification and the presence of lymph node metastases. Clinical staging of cervical cancer does not attain a good diagnostic performance, since it is incorrect in approximately one‐third of patients who undergo surgical staging. Magnetic resonance (MR) imaging resulted to be superior to clinical evaluation and computed tomography (CT) in parametrial evaluation and in the staging of uterine cervical carcinoma. Endoluminal ultrasound was introduced to analyse the cervix but no improvement in the diagnostic accuracy with respect to clinical staging was obtained. Color Doppler velocimetry was proposed as a non‐invasive tool in the examination of cervical cancer. Cervical cancers with detectable intratumoral blood flow were associated with larger size, invasion of parametrium, pelvic lymph node metastases and greater microvessel density. A ‘vascularity index’ resulted to be correlated with staging and lymph node metastases. The aims of our study were to assess color Doppler characteristics of 48 cervical cancers at different stages and to analyse the correlation between Doppler parameters and clinical–pathological features of the tumors. Three‐dimensional color power Doppler technique was used to investigate the vascular architecture of the neoplastic tissue. Three‐dimensional vascular images were compared to magnetic resonance results. The actual clinical application of the three‐dimensional vascular analysis in the evaluation of cervical cancers remains still to be defined.
宫颈癌的治疗和预后取决于基于FIGO分类的临床分期和是否存在淋巴结转移。宫颈癌的临床分期不能获得良好的诊断表现,因为大约三分之一接受手术分期的患者的临床分期是不正确的。在参数评价和宫颈癌分期方面,磁共振成像优于临床评价和计算机断层扫描。采用腔内超声对宫颈进行分析,但在临床分期方面没有提高诊断的准确性。彩色多普勒测速仪被认为是一种检查宫颈癌的无创工具。可检测到瘤内血流的宫颈癌与体积较大、参数浸润、盆腔淋巴结转移和微血管密度增大有关。“血管指数”与分期和淋巴结转移相关。我们的研究目的是评估48例不同阶段宫颈癌的彩色多普勒特征,并分析多普勒参数与肿瘤临床病理特征的相关性。采用三维彩色功率多普勒技术观察肿瘤组织的血管结构。三维血管图像与磁共振结果进行比较。三维血管分析在宫颈癌评估中的实际临床应用仍有待确定。

Background:  Nuchal translucency (NT) has been used successfully in screening for chromosomal abnormalities at 11–14 weeks of gestation. Increased NT thickness is also associated with lots of fetal anomalies in chromosomally normal fetuses. We report a case of osteogenesis imperfecta (OI), type II, presenting with increased NT thickness. A 26‐year‐old Taiwanese woman, gravida 2, para 1, without medical or family history was scanned for confirmation of menstrual gestational age at 13 weeks of gestation. Crown‐rump length was compatible with menstrual age. Increased NT thickness was noted (3.6 mm). Follow up scan 2 weeks later revealed hypomineralization of skull, multiple fractures of long bones and ribs and severe micromelia. A presumptive diagnosis of OI type II was made based on sonographic findings. After counseling, the parents decided to terminate the pregnancy. A stillborn weighing 70 g was delivered after intravaginal misoprostol application. Postmortem radiograph and autopsy confirmed the diagnosis of OI.
背景:颈透明(NT)已成功用于筛查染色体异常在妊娠11-14周。在染色体正常的胎儿中,NT厚度的增加也与许多胎儿异常有关。我们报告一例II型成骨不全症,表现为NT厚度增加。一位26岁台湾女性,妊娠2期,第1段,无病史或家族史,在妊娠13周时扫描确认月经胎龄。冠臀长度与月经年龄一致。NT厚度增加(3.6 mm)。2周后的随访扫描显示颅骨矿化程度低,长骨和肋骨多处骨折,伴有严重的小骨裂。根据超声检查结果推定为II型成骨不全。经过咨询,父母决定终止妊娠。阴道内应用米索前列醇后产下一名体重70克的死胎。死后x光片和尸检证实为成骨不全。

Thromboelastography (TEG) is a method of monitoring global homeostatic function as a dynamic process, involving the interaction between the protein coagulation cascade and platelets, as opposed to the isolated end points measured by conventional coagulation screens. The purpose of this study is to determine whether TEG variables can be used in the second trimester to predict the development of adverse pregnancy outcomes such as pre‐eclampsia and intrauterine growth restriction (IUGR defined as birth weight below the 5th centile for gestational age).
血栓弹性成像(TEG)是一种监测全局稳态功能作为一个动态过程的方法,涉及蛋白凝血级联和血小板之间的相互作用,而不是传统凝血筛查测量的孤立终点。本研究的目的是确定TEG变量是否可以在妊娠中期用于预测不良妊娠结局的发展,如先兆子痫和宫内生长受限(IUGR定义为出生体重低于胎龄第5百分位)。

Background:  Highly vascular fetal tumors can lead to death before viability as a result of vascular steal syndrome. Open fetal surgery is associated with significant risks for prematurity and maternal morbidity. Various local ablative techniques have been tried to reduce tumor vascularity, with variable success. Radiofrequency ablation has been performed for sacrococcygeal teratoma, but cervical teratoma poise further significant challenges with its proximity to vital neck structures.

The importance of fluid analysis in the evaluation of intraperitoneal cysts in female fetuses is demonstrated. Case 1: A 30‐year‐old woman had an unremarkable pregnancy until 29 gestational weeks, when a routine US examination revealed an anechoic cyst of 4.0 cm in diameter located in the lower abdomen of a female fetus. At 33 weeks of gestation the cyst enlarged to 6.5 cm. Intrauterine aspiration of the cyst was performed. A volume of 75 mL of yellow fluid was obtained and collapse of the cyst was noted. Fluid biochemistry revealed estradiol >200000 pg/mL, progesterone 1648 ng/mL, creatinine undetectable. A fetal ovarian cyst was diagnosed. At 34 weeks of gestation the cyst enlarged again to 6 cm and 78 mL of yellow fluid was obtained on intrauterine aspiration. Again, collapse of the cyst was noted on US. Repeated scans until birth showed an anechoic cyst of 4.0 cm. Postnatal abdominal US confirmed the diagnosis and a complete disappearance of the cyst after 2 weeks. Case 2: A 28‐year‐old woman had an unremarkable pregnancy until 34 gestational weeks, when a routine US examination revealed an anechoic cyst of 6.0 cm in diameter located in the lower abdomen of a female fetus. Intrauterine aspiration of the cyst was performed. A volume of 147 mL of yellow fluid were obtained and collapse of the cyst was noted. Fluid biochemistry revealed estradiol 781 pg/mL, progesterone 37 ng/mL, and creatinine 4 mg/dL. An unusual urinary tract malformation was diagnosed. Repeated scans until birth showed an anechoic cyst of 6 cm. After delivery a fistula between the urinary bladder and the upper vagina, and an imperforated hymen, were diagnosed. In cases of prenatal needle aspiration, fluid biochemistry may be helpful to establish the origin of intraperitoneal cysts in the female fetus, especially when recurrence occurs, and prevent unnecessary attempt of decompression of intraperitoneal cysts.
液体分析在评估女性胎儿腹膜内囊肿的重要性被证明。病例1:一名30岁的女性在妊娠29周之前妊娠情况平平,在一次常规的超声检查中发现一个位于女性胎儿下腹直径4.0 cm的无回声囊肿。在妊娠33周时,囊肿增大到6.5厘米。行囊肿宫内抽吸术。体积为75 mL的黄色液体,囊肿塌陷。液体生化显示雌二醇>200000 pg/mL,孕酮1648 ng/mL,肌酐未检出。诊断为胎儿卵巢囊肿。妊娠34周,囊肿再次增大至6cm,宫内吸出黄色液体78 mL。再一次,超声显示囊肿塌陷。反复扫描直到出生显示一个4.0厘米的无回声囊肿。产后腹部超声证实了诊断,2周后囊肿完全消失。病例2:一名28岁的女性在妊娠34周之前妊娠情况不明显,在一次常规超声检查中发现一个女性胎儿下腹直径6.0 cm的无回声囊肿。行囊肿宫内抽吸术。检出147ml黄色液体,囊肿塌陷。液体生化显示雌二醇781 pg/mL,孕酮37 ng/mL,肌酐4 mg/dL。诊断为不寻常的尿路畸形。反复扫描直到出生显示一个6厘米的无回声囊肿。分娩后,膀胱和上阴道之间的瘘管和处女膜未穿孔被诊断出来。在产前针吸的情况下,液体生物化学可能有助于确定女性胎儿腹膜内囊肿的起源,特别是当发生复发时,并防止不必要的腹膜内囊肿减压尝试。

In cases of prenatal needle aspiration, fluid biochemistry may be helpful to establish the origin of intraperitoneal cysts in the female fetus, especially when recurrence occurs, and prevent unnecessary attempt of decompression of intraperitoneal cysts.","PeriodicalId":23453,"journal":{"name":"Ultrasound in Obstetrics and Gynecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83453917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction:  Preterm delivery has been faced in all delivery with a 7–11% and it keeps its importance by causing perinatal mortality and morbidity. Therefore it is important to define preterm delivery risk during the earlier period of the delivery.
前言:早产在所有分娩中所占的比例为7-11%,早产对围产期的死亡率和发病率有着重要的影响。因此,在分娩早期确定早产风险是很重要的。
