O-37: Yolk Sac Diameter and Embryonic Heart Rate As Prognostic Factors of First Trimester Spontaneous Miscarriage
Background: During the past 20 years a lot of information is achieved about the first trimester of pregnancy through ultrasound and intrauterine fertilization. Many researchers tried to use the symptoms of ultrasound in early pregnancy like measuring the gestational sac and yolk sac of the pregnancy to predict the continuation of pregnancy. Aim of the recent study is to predict the risk of spon...
متن کاملNormal ranges of embryonic length, embryonic heart rate, gestational sac diameter and yolk sac diameter at 6-10 weeks.
OBJECTIVES To construct normal ranges for embryonic crown-rump length (CRL), heart rate (HR), gestational sac diameter (GSD) and yolk sac diameter (YSD) at 6-10 weeks of gestation. METHODS We examined 4,698 singleton pregnancies with ultrasound measurements of CRL, HR, GSD and YSD at 6-10 weeks and CRL at 11-13 weeks resulting in the live birth after 36 weeks of phenotypically normal neonates...
متن کاملEvaluation of Yolk Sac Diameter and Embryonic Heart Rate as Prognostic Factors of Gestational Outcome in Early Singleton Pregnancies
It has been previously suggested that abnormal yolk sac characteristics and slow embryonic foetal heart rate are associated with poor gestational outcome and these parameters can be used to assess foetal viability in first trimester of pregnancies. However there is paucity of evidence in Indian medical literature. The purpose of present study was to examine the role of yolk sac characteristics ...
متن کاملYOLK SAC TUMOR OF VAGINA
Malignant germ-cell tumors (MGCT) are rare tumors of childhood accounting for less than 3% of pediatric malignancies. Endodermal sinus tumor (EST) forms the most common histologic subtype of MGCT. The vagina is an extremely rare site for GCTs. An 8-month-old female was admitted with a short history of vaginal bleeding, and a mass protruding from the vagina. She was pale and a mass was palpab...
متن کاملYolk Sac Cultivation of Tumors
Some months ago there was published from this laboratory a brief preliminary report of a method whereby tumors could be cultivated in the yolk sacs of developing chick embryos (4). Neoplasms were first injected into the yolk sac with the idea that the tumor cells would die and disintegrate, thus releasing any virus that might be present. It was hoped that if such a release occurred the medium p...
