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.","PeriodicalId":23453,"journal":{"name":"Ultrasound in Obstetrics and Gynecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90323656","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}

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.

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.","PeriodicalId":23453,"journal":{"name":"Ultrasound in Obstetrics and Gynecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84355777","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}
