What Significance: Stagnant Sac, Increased Yolk?

Published on, 07 February, 2024. Answered by Dr. Mini Sood and Verified by Dr.Galen Team
Patient Question

Hello Doctor,


Could the lack of growth in gestational sac diameter despite an increase in yolk sac size, along with the absence of a fetal pole or cardiac activity, indicate a blighted ovum in my 6-week pregnancy, despite my HCG levels being 9217 miu/ml?

Answered by Dr. Mini Sood


Thank you for reaching out to Dr.Galen. Please find the below response to your query.


Interpreting Ultrasound Findings:

1. The lack of significant change in gestational sac diameter over a 7-day period is concerning.

2. An increased yolk sac size without corresponding fetal pole development raises potential red flags.


Potential Concern: Blighted Ovum

1. The absence of a visible fetal pole or cardiac activity despite advancing gestational age may indicate a blighted ovum.

2. A blighted ovum occurs when a fertilized egg implants in the uterus but doesn't develop into a viable embryo.
