Blighted ovum is :
Correct Answer: Avascular villi
Description: Ans. is b i.e. Avascular villi According to the clinical and echographic findings, it is possible to separate early pregnancy losses into two groups : alighted ova : Those early pregnancy losses in which foetal development is not observed with ultrasound (so that only a gestational sac is present with or without a yolk sac) and fetal tissue is absent on histologic examination of the products of conception. * Early Fetal demise Those early pregnancy losses in which fetal development is clearly observed by ultrasound and feta! tissue is found on the histologic examination. The difference between these two types of aboion is of fundamental impoance. The lack of development of fetal structures defines a subset of aboions of genetic origin. In contrast, the early interruption of fetal life is a complex phenomenon with multiple etiologies. Therefore, the patients with blighted ova do not require extensive work up, whereas patients who have aboed cytogenetically normal fetuses need an extensive search for non genetic factors responsible for the pregnancy loss.
