Dichorionic Diamniotic Twin

Figer-1

📄 Report Sample Line- Dichorionic Diamniotic Twin
Two distinct placental masses are visualized (or a single fused placenta with a thick intertwin membrane), with the presence of the ‘twin peak’ (lambda) sign at the intertwin membrane insertion site, confirming dichorionicity. Each fetus is housed in a separate amniotic sac with independent and normal amniotic fluid volumes. Both fetuses demonstrate appropriate biometric measurements for gestational age with no evidence of growth discordance, structural anomalies, or amniotic fluid abnormalities. Umbilical artery Doppler studies for both twins are within normal limits.


Conclussion: 📋 Findings are consistent with an uncomplicated dichorionic diamniotic twin pregnancy. Fetal growth is appropriate for gestational age, with no current sonographic evidence of growth restriction, fluid imbalance, or twin-related complications
Recommendation: Serial growth monitoring every 4 weeks

1. Dichorionic diamniotic (DCDA) twins are characterized by: 1. डाइकोरियोनिक डाइएमनिओटिक (DCDA) जुड़वाँ किस तरह पहचाने जाते हैं?
A. Each twin has its own chorion and amnion (separate placentas or fused placentas); intertwin membrane present
B. Shared single sac without membrane
C. Always conjoined twins
D. Only seen in triplet pregnancies

2. The ultrasound sign most helpful to identify dichorionicity in the first trimester is: 2. प्रारंभिक तिमाही में डाइकोरियोसिटी की पहचान के लिए सबसे सहायक अल्ट्रासाउंड संकेत क्या है?
A. Lambda (twin peak) sign at the placental junction
B. T‑sign (no lambda)
C. Visualization of cord entanglement
D. Only maternal serum test

3. Compared with monochorionic twins, DCDA twins have which relative risk profile? 3. मोनोकोरियोनिक जुड़वाँ की तुलना में DCDA जुड़वाँ का जोखिम प्रोफ़ाइल कैसा होता है?
A. Lower risk of twin‑to‑twin transfusion syndrome (TTTS) and intertwin vascular complications
B. Higher risk of TTTS
C. Guaranteed normal outcome
D. Always lethal

4. When is chorionicity best determined by ultrasound? 4. अल्ट्रासाउंड द्वारा चोरियोसिटी कब सबसे अच्छी तरह निर्धारित की जाती है?
A. First trimester (ideally 6–13 weeks) when membranes and placenta are most distinct
B. Only after 30 weeks
C. At delivery only
D. Chorionicity cannot be determined

5. A common management recommendation for uncomplicated DCDA twins is: 5. अनसुस्पष्ट DCDA जुड़वाँ के लिए एक सामान्य प्रबंधन सिफारिश क्या है?
A. Routine antenatal surveillance with growth scans and individualized care; delivery usually later than monochorionic twins (often 37–38 weeks if stable)
B. Immediate delivery at 28 weeks always
C. No antenatal scans needed
D. Routine cord entanglement checks

6. Which complication is still more common in twin pregnancies (including DCDA) than in singletons? 6. जुड़वाँ गर्भधारणों (DCDA सहित) में कौन‑सी जटिलता एकल गर्भधारण की तुलना में अभी भी अधिक सामान्य है?
A. Preterm birth and growth discordance
B. Lower risk of preterm birth than singletons
C. Always normal placental function
D. No need for maternal care

7. The presence of two separate placentas on ultrasound always guarantees dichorionicity. True or false? 7. अल्ट्रासाउंड पर दो अलग प्लेसेंटास की उपस्थिति क्या हमेशा डाइकोरियोसिटी की गारंटी देती है? सच्चा या गलत?
A. Generally true — two separate placentas indicate dichorionicity, but fused placentas can rarely appear as single placental mass; early scan is best
B. Always false
C. Only maternal blood test can tell
D. Placental number is irrelevant

8. Which twin complication is uncommon in DCDA but common in monochorionic twins? 8. कौन‑सी जुड़वाँ जटिलता DCDA में असामान्य है परन्तु मोनोकोरियोनिक जुड़वाँ में आम है?
A. Twin‑to‑twin transfusion syndrome (TTTS)
B. Preterm birth
C. Cesarean delivery
D. Maternal nausea

9. Counseling points for parents expecting DCDA twins should include: 9. DCDA जुड़वाँ की उम्मीद करने वाले माता‑पिता के लिए परामर्श बिंदुओं में क्या शामिल होना चाहिए?
A. Explain chorionicity, risks higher than singletons (preterm birth, growth discordance), surveillance schedule, and likely delivery timing; reassure lower risk of TTTS compared with monochorionic twins
B. Assure no extra risk and no special scans
C. Immediate recommendation for termination
D. Only maternal diet changes

10. Typical surveillance schedule for uncomplicated DCDA twins often includes: 10. अनकंप्लिकेटेड DCDA जुड़वाँ के लिए विशिष्ट निगरानी अनुसूची में सामान्यतः क्या शामिल होता है?
A. Growth scans every 3–4 weeks from mid‑trimester and antenatal visits with individualized frequency; consider delivery ~37–38 weeks if stable
B. No scans after booking
C. Daily fetal MRI
D. Immediate delivery at 28 weeks
