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 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 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 کاملLong-term outcome and prognostic factors for yolk sac tumor of the ovary.
Yolk sac tumors of the ovary (YST) are rare and highly malignant tumors occurring in children and young adults. Because of its rarity, YST prognostic factors remain unclear. Our purpose was to evaluate the prognostic factors in YST. We performed a retrospective review of 36 patients with pure YST from 1986 to 2006. The 5-year overall survival and progression-free survival were 66.6% and 68.8%, ...
متن کاملQuantitative assessment of gestational sac shape: the gestational sac shape score.
OBJECTIVE To develop a quantitative method for characterizing gestational sac shape. METHODS Twenty first-trimester gestational sacs in normal pregnancies were studied with three-dimensional (3D) ultrasonography. The 3D coordinates of surface-point sets were obtained for each sac using 30-, 15- and six-slice sampling. Cubic spline interpolation was used with the 15- and six-slice surface-poin...
