Evaluation of Gestational Sac Diameter, Crown Rump Length, Yolk Sac Diameter and Fetal Heart Rate in Early Detection of Congenital Fetal Malformation

Congenital abnormalities impact 3% to 5% of allpregnancies, and they are the leading cause newborndeath. The majority caused by unknown factors, withpregnancy being sole risk factor. However, in bothaffluent developing nations, responsible forrising newborn fatalities.Aim study: purpose this study was seewhether there a link between Gestational sac diameter,crown rump length, yolk diameter fetal heart ratein detection early congenital malformation.Patients methods:our research included 100 pregnantwomen who were scanned using 2d ultrasonographybeginning first trimester, with scan takingplace 6 8 weeks. at 18-22 weeks, followup performed. trimester's outcome wasdocumented.Results: Among cases, 77 (77%) had normal pregnancy,20 (20%) an miscarriage, 3 (3%) congenitalfetal malformation. statistically highly significantdifference normal, miscarriage andcongenital malformation results regardingyolk shape (p < 0.001). our research, small,irregular, calcified, or big significantpredictive factor pregnancy outcome.Conclusion: strong gestationalsac diameter, CRL, andfetal rate pregnancies that ended firsttrimester.
