Dichorionic Placentation

Figer-1

📄 Report Sample Line- Dichorionic Placentation
Two separate placental masses are identified (or a single bilobed placenta with a thick inter-twin membrane), with a clearly visualized thick dividing membrane and twin peak (‘lambda’) sign at the placental insertion site, confirming dichorionicity. Each fetus lies in a separate amniotic sac with independent amniotic fluid volumes. Both fetuses exhibit appropriate growth parameters for gestational age, with no evidence of growth discordance or structural anomalies. Doppler studies are within normal limits for both twins.


Conclussion: 📋 Findings are consistent with a dichorionic diamniotic twin pregnancy with appropriate fetal growth, normal amniotic fluid volumes, and unremarkable Doppler assessments. No evidence of twin-related complications at the time of scan.
Recommendation: Routine follow-up scans every 4 weeks to monitor fetal growth and well-being.

D. Two fetuses sharing one amniotic sac

2. Which ultrasound sign favors dichorionicity? 2. कौन सा अल्ट्रासाउंड संकेत डाइकॉरिओनिसिटी की ओर इशारा करता है?
A. Lambda (twin peak) sign at the inter-twin membrane
B. Thin T-sign
C. Single placenta with vascular anastomoses

B. Lower risk of vascular complications like TTTS
C. Always fused placentas
D. Require laser therapy routinely

B. T-sign at membrane insertion
C. Single placenta only
D. Identical fetal sex always

6. If two placentas are seen and well separated, this suggests: 6. यदि दो प्लेसेंटा दिखाई देते हैं और अच्छे से अलग हैं, तो यह क्या संकेत देता है?
