P09.15: Three‐ and four‐dimensional ultrasound: when and how to obtain the best images?

Abstract

We report the prenatal findings of cystic hygroma. Nuchal cystic hygromas are characterized by single or multiple congenital cystics of the lymphatic system, most found within the soft tissues of the neck. Embriology are the clinical consequence of a delay or absence of the communications that normally develop between the jugular lymph sacs and the internal jugular veins; the obstucted jugular lymph sacs dilate along the paths of least resistence into the posterior and lateral cervical areas. A 26-year-old woman, gravida 1, was referred at 24 weeks gestation to our department from another hospital where sonographic diagnosis of neck masses had been made. Twoand three-dimensional sonographic confirmed the presence of a large cystic areas with septa termed cystic hygroma develop within the skin in the right lateral aspect of the neck, without other malformations. Examination in utero using Magnetic resonance imaging (MRI) had been made to study this case. P09.14 Relationships between pregnancy rates following in vitro fertilization or intracytoplasmic sperm injection and endometrial thickness and pattern M. Sadeghi, B. Hossein Rashidi, M. Jafarabadi, E. Shahrokh Tehraninejad Valiasr Reproductive Health Research Center, Islamic Republic of IranObjective: To investigate the role of endometrial thickness and pattern on day of human chorionic gonadotropin (hCG) administration on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcome. Study Design: A total of 150 infertile women undergoing embryo transfer after IVF/ICSI cycles were studied in a prospective survey. Sonographic features of the endometrium (thickness and pattern) on the day of hCG administration, hormonal profile (progesterone, estradiol, FSH, LH) and various other variables (maternal age, causes and duration of infertility, duration of treatment, number of human menopausal gonadotropin (hMG) ampoules administered, and number of oocytes retrieved) were evaluated. These variables in pregnant and non pregnant patients were compared. Results: There was no difference between pregnant and non pregnant patients in mean endometrium thickness (10.1 ± 1 versus 10.2 ± 2, p = 0.79). Pregnancies occurred only in patients with an endometrial thickness of 9-12 mm (p = 0.036). Duration of treatment, number of hMG ampoules administered, and number of oocytes retrieved, estradiol concentration, and estradiol/progesterone ratio on the day of hCG administration differed significantly between pregnant and non pregnant patients. The receiver-operating characteristic (ROC) curve and multiple logistic regressions showed no significant effect of endometrial thickness in outcome of IVF/ICSI. Conclusion: The sonographic features of endometrium (thickness and pattern) on the day of hCG administration did not differ between pregnant and non pregnant patients. The pregnancy rate declined beyond two limits of endometrial thickness. P09.15Three-and four-dimensional ultrasound: when and how to obtain the best images?
