Air bubble location inside the uterus after transfer: is the embryo really there?
2007
Objective To demonstrate that the location of the air bubble after embryo transfer (ET) does not necessarily indicate the final embryo location. Design Case report. Setting Private clinic. Patient(s) A couple with primary infertility for whom a diagnosis of bicornuate uterus with a very open angle between horns was confirmed. Intervention(s) Laparoscopy and hysteroscopy were performed before an IVF cycle in which a single embryo was replaced. Main Outcome Measure(s) Air bubble image immediately after ET and gestational sac location 3 weeks later. Result(s) Immediately after a single ET, the air bubble was seen in the left uterine horn. Three weeks later, a gestational sac was seen in the ri…
Improved accuracy of hysteroembryoscopic biopsies for karyotyping early missed abortions
2003
Abstract Objective To assess the potential of direct embryo and chorion biopsies obtained by hysteroembryoscopy for karyotyping early missed abortions. Design Clinical prospective descriptive study. Setting Instituto Valenciano de Infertilidad, Valencia, Spain. Patient(s) Sixty-eight women (71 gestational sacs) with missed abortions. The gestational age on ultrasound was 6.3 weeks (range, 4–10 weeks). Intervention(s) Transcervical hysteroembryoscopy before curettage. Main outcome measure(s) Comparison between the cytogenetic results from hysteroembryoscopic biospies and those of the curettage material. Result(s) Hysteroembryoscopic biopsies could be taken in 97.2% of the gestational sacs. D…
Posters Early pregnancy P01First trimester normograms for a wide variety of ultrasound, hemodynamic and serum parameters
2000
Background The aim of the study was to assess prospectively the evolution of multiple clinical parameters throughout the first trimester of pregnancy. Method A transvaginal ultrasound examination and a blood test was weekly performed until the 13th gestational week in a group of healthy volunteers. A total of 25 spontaneously conceived singleton pregnant women with good pregnancy outcome finally completed the study. The evolution of 10 transvaginal ultrasound parameters, 5 Doppler measurements and 6 serum parameters was studied. Results An increasing trend with advancing gestation was evident for the mean gestational sac (MSD) and amniotic sac (AS) diameters, trophoblastic rim, CRL and seru…
F117Hystero-embryoscopic findings in early nonviable pregnancies
2000
Background A high proportion of early pregnancy losses are associated to abnormal embryo development. However, chromosomal analysis of routine curettage samples are of limited value; and histopathological examinations of the embryos are rarely performed in clinical practice. Method A transcervical hystero-embryoscopy was performed prior to the curettage in 31 nonviable first-trimester pregnancies and a control group of 5 early terminations of pregnancy. In the study group, the estimated gestational age according to the ultrasound findings was 6.7 (4–9) menstrual weeks. Direct biopsies of different gestational structures were taken during the endoscopic procedure. Results In nonviable pregna…
Conservative treatment of ectopic pregnancies using a single echo-guided injection of methotrexate into the gestational sac
1991
The authors describe the possibility of the conservative treatment of five early ectopic pregnancies. A single injection of methotrexate into the tubal gestational sac was performed under vaginal ultrasound guidance. In all five cases, a clear ectopic gestational sac could be visualized. The pregnancies dated from the 5th to the 7th week of amenorrhea. Strict ultrasound follow-up following injection showed a gradual reduction in the size of the tubal gestational sac. At the same time, plasma beta-hCG gradually decreased to zero after a maximum time period of 25 days. Subsequent hysterosalpingography performed on all of the women demonstrated bilateral normal patent tubes. It is concluded th…
