OBJECTIVE To determine the influence of the position of the fetal neck on nuchal translucency measurement. DESIGN A prospective cross-sectional study. POPULATION One hundred and ninety-six. METHODS Nuchal translucency was measured in the mid-sagittal plane, with the fetal neck in the flexed, neutral and extended positions. Measurements were made to(More)
OBJECTIVE To determine the value of early pregnancy sonography in detecting fetal abnormalities in an unselected obstetric population. DESIGN Prospective cross-sectional study. All women initially underwent transabdominal sonography and when the anatomical survey was considered to be incomplete, transvaginal sonography was also performed (20.1%). Nuchal(More)
The increasing use of laparoscopic surgery with more complicated procedures means that the use of multiple and larger ports is becoming commonplace. One well-known risk associated with the use of ports more than 10 mm in diameter is the development of an incisional hernia unless the deep fascia is closed adequately. This complication is estimated to follow(More)
OBJECTIVES To assess the sonographic screening for anencephaly in the first trimester in a low-risk obstetric population. METHODS Since 1994, 5388 women attended our clinic for a first-trimester scan (11-14 weeks of gestation) and screening for structural and chromosomal abnormalities. The patients underwent transabdominal scanning, and transvaginal(More)
Primary retroperitoneal ectopic pregnancy represents an extremely unusual entity with a rather obscure pathogenesis. Implantation in the retroperitoneal space has been reported to occur both spontaneously and with use of assisted reproduction techniques. The pelvic and the upper retroperitoneum have both been involved, and implantation in the most unusual(More)
Objective. The aim of this study was to investigate the extent of placental lesions associated with blood pressure (BP) levels in pregnancies complicated by hypertension. Methods. 55 singleton pregnancies complicated by mild hypertension were recruited and compared to 55 pregnancies complicated by severe hypertension. The histological assessment was carried(More)
We conducted this prospective cohort study to standardize our laparoscopic technique of excision of posterior deep infiltrating endometriosis (DIE) nodules, according to their size, location, and geometry, including 36 patients who were grouped, according to principal pelvic expansion of the nodule, into groups with central (group 1) and lateral (group 2)(More)
OBJECTIVE To determine the significance of certain soft ultrasonographic markers for chromosomal abnormalities in the first trimester. DESIGN This was a prospective cross-sectional study. SETTING University Department of Obstetrics and Gynaecology, London, UK. METHODS A total of 5385 women from an unselected population underwent a detailed assessment(More)
OBJECTIVE To analyze the value of second trimester ultrasound examination among those women whose fetuses were indicated to be at low risk of chromosomal anomalies on the basis of both first trimester nuchal translucency measurement and second trimester biochemical screening. METHODS A retrospective study of 5500 pregnancies carried out at the fetal(More)
OBJECTIVE To analyze the incidence of negative cone biopsies and evaluate the significance of the findings. STUDY DESIGN The study population consisted of women who underwent cervical conization at a university teaching hospital from February 1996 to December 2001. Three modalities were used for conization: CO2 laser, large loop excision of the(More)
