Objectives: To evaluate whether endometrial or ovarian parameters as measured using 3-D power Doppler ultrasound can predict the outcome in frozen embryo transfer (FET) cycles. Methods: 30 women with no known gynecological pathology (e.g. endometriosis, fibroids, any operation to gynecological organs) undergoing FET were recruited. FET was carried out in natural menstrual cycle 3–4 days after the first positive LH test result. A transvaginal 3-D ultrasound examination (Voluson Expert 730, Kretz Zipf, Austria) was performed on the day of FET and repeated about one week later, at the time of expected implantation. The outcome measures were endometrial pattern, thickness, volume, vascularization index (VI), subendometrial volume and VI, dominant and non-dominant ovarian volume and VI. The subendometrial region was considered to be 5 mm beneath the border between endometrium and myometrium. At the second visit no power Doppler was used to examine the endometrium. Results: The demographic, clinical and embryological characteristic were similar between pregnant (15/30) and nonpregnant groups (15/30) (Table). There were no differences between the groups in endometrial/subendometrial thickness, volume or VI. The endometrial triple line pattern was more often present in the pregnant group on the day of FET (93.3% vs. 40.0%, 95% CI 25.5–81.2%). No differences in the ovaries were observed on the day of FET (Table). At the second visit the triple line pattern was also more often present in those patients who conceived (91.7% vs. 42.9%, 95% CI 18.5–79.1%), but still no differences were observed in the dominant ovarian vasculature (Table). Conclusions: According to our results, measurement of power Doppler indices using 3-D ultrasound on the day of FET does not provide us any additional information concerning the outcome of the cycle. The existence of triple line pattern on the day of FET seems to be prognostic sign of a prosperous outcome after FET.
目的:评价三维功率多普勒超声测量子宫内膜或卵巢参数是否可以预测冷冻胚胎移植(FET)周期的结局。方法:选取30例未见妇科病理(如子宫内膜异位症、子宫肌瘤、任何妇科器官手术)的女性进行FET手术。在首次LH阳性后的自然月经周期3-4天进行FET。在FET当天进行经阴道三维超声检查(Voluson Expert 730, Kretz Zipf, Austria)，并在大约一周后预期植入时重复检查。结果测量为子宫内膜形态、厚度、体积、血管化指数(VI)、子宫内膜下体积和VI、优势和非优势卵巢体积和VI。子宫内膜下区域被认为是子宫内膜和子宫肌层之间边界以下5mm。在第二次就诊时，未使用功率多普勒检查子宫内膜。结果:妊娠组(15/30)和非妊娠组(15/30)的人口学、临床和胚胎学特征相似(表)。各组间子宫内膜/子宫内膜下厚度、体积或VI均无差异。子宫内膜三线模式在妊娠组FET当天更为常见(93.3% vs. 40.0%， 95% CI 25.5-81.2%)。FET当天卵巢未见差异(表)。在第二次就诊时，怀孕的患者也更常出现三线模式(91.7%对42.9%，95% CI 18.5-79.1%)，但在优势卵巢脉管系统中仍未观察到差异(表)。结论:根据我们的研究结果，在FET当天使用三维超声测量功率多普勒指数并没有为我们提供任何关于周期结果的额外信息。三线模式在FET当天的存在似乎是FET后预后良好的预兆。

We report here an epigastric heteropagus conjoined female twins case which was characterized by a completely formed fetus with an omphalocele and an adjacent second body consisting with a pelvis and two lower extremities. There was not a bowel or bony connections and there was a thin vascular pedicle between twins. The diagnosis was made with three dimensional ultrasonography at 18 weeks of gestation.

Objectives: To explore the diagnostic value of antenatal ultrasound combining with in utero magnetic resonance imaging (MRI) in multiplets malformations, and analyze their advantages and limitations. Methods: In the period between 2004 and 2007, 105105 fetuses received ultrasound examination in our hospital. 268 cases were multifetation, including 64 multiplets malformations. And of them 11 multiplets malformations (gestational age ranged from 14–31 weeks), including 8 cases of twin pregnancy and 3 of triplet pregnancy, received MRI examination within 48 hours after ultrasound, all confirmed by autopsy. Retrospectively analyzed, the results of antenatal ultrasound and in utero MRI were compared. Results: In 11 multiplets malformations, there were 6 conjoined twins and 5 acardiac twins with twin-reversed arterial perfusion (TRAP). MRI gave identical diagnostic results with ultrasound, but each had different advantages. (1) MRI was superior to ultrasound in the following aspects: 1. the large view with visualization 2 or 3 fetal organs, even the whole fetus, placenta and amniotic sac simultaneously; 2. visualizing diprosopy of cephalopagus and identifying complex intracranial structures clearly; 3. identifying internal organs of conjoined twins; 4. demonstrating the insertion of umbilical core and the connection with fetus and placenta in acardiac twin.; 5. It showed ‘‘leopard stripe sign’’ in placenta of acardiac twin. (2) Ultrasound was superior to MRI in two aspects: 1. detecting hemodynamic change in TRAP; 2. evaluating cardiac function and finding cardiac anomalies, such as hemicardia of acardiac twin. Conclusions: Ultrasound and MRI are complement with each other in diagnosing multiplets malformations, The combining application of ultrasound and MRI could improve the diagnostic accuracy on multiplets malformations

as maternal age, ovarian reserve, serum estradiol concentrations, follicular number and size are being investigated as possible prognostic factors of success. In regard to the oocyte quality at the time of retrieval, a relationship between follicular vascularization and the IVF outcome has been established. Conventional pulsatility indices of intra-ovarian arteries are very difficult to use routinely. The aim of this study was to investigate the accuracy of power Doppler ultrasonography for assessment of follicular vascularization during IVF attempts, as well as a prognostic factor of IVF outcome. Methods: 35 patients undergoing IVF treatment were prospectively recruited. Using power Doppler ultrasound, we assessed individual follicular vascularization of about three follicules in each ovary, by a subjective graduation, at the time of oocyte collection. Using a validated system, follicles were determined to be at high or low grade on regard with the extension of vascularization. Subsequent follicular and oocyte quality parameters were collected: mean follicular diameter, presence and maturity of the corresponding oocyte, quality of zygotes and cleaved embryos whether transferred or not. Results: A total of 187 follicles were studied. The assessment of perifollicular vascularization, although highly subjective, was feasible in 92.51% of cases. Vascularization grade was not dependent on follicular size. There was no significant difference in any of the analysed follicular and oocyte quality parameters between high and low grade follicles. Conclusion: Power Doppler assessment of perifollicular vascularization does not seem to be a useful procedure to evaluate follicular and oocyte quality.

After birth three children showed neurological handicaps in two cases due to postnatally detected syndromes: one Sotos syndrome and one Goldenhar syndrome and one case related to progression of the ventriculomegaly. Conclusions: The outcome of fetuses with isolated mild ventriculomegaly is mostly favorable. Chromosomal anomalies should be excluded in all cases with MVM since in 4.1% of the fetuses trisomy 21 was proven. The risk for a chromosomal anomaly is higher when additional soft markers for aneuploidy are present. Previously published studies on this topic did not take the role of soft markers into consideration. In cases with MVM accompanied by normal karyotype the risk for prenatal and postnatal mortality and morbidity is increased as compared to sonographically normal fetuses.

and relate the results to studies on ultrasound diagnosis in view of necessity of surgical intervention. Material and Methods: Two-hundred and thirty-four ovaries of postmenopausal women, who had died from non-gynaecological diseases, were examined prospectively and consecutively, by the pathologist (G.P. Blom), for cystic structures. The results were compared to recent ultrasound studies of adnexal cysts. Results: Ovarian cysts were found in 15.4% of the women. Paraovarian cysts were found in 4.7% of the women. All cysts were benign, except for one woman, who had bilateral serous cystadenoma of borderline type. Macroscopically the borderline cysts were multilocular with mean diameters of 60 mm and 15 mm, respectively. Conclusions: The results were in agreement with diagnostic ultrasound studies. The fact that we found benign ovarian and paraovarian cysts in 21.1% of the women should in our opinion make the gynecologists reconsider the need for surgical intervention in favor of follow-up.
