The aim of our study was to measure the volume of gestational sac and amniotic sac in physiological pregnancies and missed abortion. We wanted to create nomograms for individual weeks of gestation.

Retrospective cohort study.

Institute for the Care of Mother and Child, Prague.

The study randomized 413 women after spontaneous conception. The patients were divided into two groups: women with physiological pregnancy and childbirth in the period (374), and women with pregnancy terminated by missed abortion. Both groups were performed measurement volume of gestational and amniotic sac in the first trimester of pregnancy. Analysis was performed using 4D View software applications, and volume calculations were performed using VOCAL (Virtual Organ Computer Aided anaLysis).

We have created the first in the Czech Republic nomograms volumes of gestational and amniotic sac in physiological pregnancies and missed abortion. We performed a correlation between the size of gestational sac and prosperity pregnancy.

In our study we found no correlation between the volume of gestational sac and the development of the pregnancy.
