📄 Report Sample Line - Single FDIU in Stuck Twin Syndrome

Diamniotic monochorionic twin gestation. One twin (Twin A) shows no detectable fetal cardiac activity or movements, with measurements corresponding to a gestational age of approximately 15 weeks. Twin A appears compressed against the uterine wall with oligohydramnios, consistent with "stuck twin" appearance. The amniotic sac is severely reduced in volume, and fetal anatomy is difficult to assess due to crowding. The co-twin (Twin B) with measurements corresponding to a gestational age of approximately 20 weeks demonstrates normal cardiac activity and active movements with adequate amniotic fluid volume and biometric parameters appropriate for gestational age. Placenta is single and shared. Twin-Twin Transfusion Syndrome (TTTS) Stage II–III features may be present.

Conclusion: 📋 Findings suggestive of Single Fetal Demise (FDIU) in Monochorionic Diamniotic Twin Pregnancy, with features of Stuck Twin Syndrome. Twin A: FDIU; Twin B: Viable.

Recommendation: Evaluate for complications such as anemia, neurological sequelae, or TTTS progression.

1. "Stuck twin" syndrome typically refers to: 1. "स्टक ट्विन" सिंड्रोम सामान्यतः किसे दर्शाता है?

B. A twin stuck in the birth canal during delivery
C. Both twins with polyhydramnios
D. A twin with placental abruption only

2. The major factor that determines risk to the surviving twin after single FDIU in stuck twin syndrome is: 2. स्टक ट्विन सिंड्रोम में सिंगल FDIU के बाद जीवित जुड़वाँ के जोखिम को निर्धारित करने वाला प्रमुख कारक क्या है?
A. Chorionicity and presence of placental vascular anastomoses (monochorionic vs dichorionic)
B. Maternal age
C. Fetal sex
D. Maternal BMI

3. In monochorionic twins with placental anastomoses, demise of one twin commonly risks: 3. प्लेसेंटल एनोस्तोमोसिस वाले मोनोकोरियोनिक जुड़वां में, एक भ्रूण की मृत्यु आमतौर पर किस जोखिम से जुड़ी है?
A. Maternal hypertension only
B. No risk to surviving twin
C. Acute haemodynamic shift through anastomoses causing ischemic brain or organ injury in survivor
D. Guaranteed term delivery without complications

4. Immediate steps after diagnosis of single FDIU in stuck twin syndrome should include: 4. स्टक ट्विन सिंड्रोम में सिंगल FDIU के निदान के बाद तत्काल कदमों में क्या शामिल होना चाहिए?
A. Confirm chorionicity, perform detailed ultrasound with fetal Dopplers, consider fetal MRI and infection screen; counsel parents
B. Immediate cesarean delivery in all cases
C. Start maternal chemotherapy
D. No evaluation required

5. Fetoscopic laser photocoagulation in TTTS aims to: 5. TTTS में फेटोस्कोपिक लेज़र फोटोकोएगुलेशन का उद्देश्य क्या है?
A. Increase amniotic fluid in donor twin directly
B. Ablate placental vascular anastomoses to stop transfusion imbalance
C. Deliver the babies immediately
D. Always prevent fetal demise

6. After single fetal demise in stuck twin syndrome, best surveillance for the surviving twin includes: 6. स्टक ट्विन सिंड्रोम में एक भ्रूण मृत्यु के बाद जीवित जुड़वाँ के लिए सर्वश्रेष्ठ निगरानी में क्या शामिल है?
A. Serial ultrasound for growth, umbilical and middle cerebral artery Dopplers, CTG/NST as indicated; consider fetal MRI if neurological concern
B. Single ultrasound only
C. Immediate delivery at any gestation
D. No monitoring required

7. Which finding increases the likelihood of adverse neurodevelopmental outcome in the surviving twin? 7. किस खोज से जीवित जुड़वाँ में प्रतिकूल नयूरोविकासात्मक परिणाम की संभावना बढ़ जाती है?

B. Abnormal cerebral findings on MRI or abnormal MCA/umbilical Dopplers
C. Late-term delivery only
D. Maternal skin rash

8. Indication for earlier delivery of the surviving twin would be: 8. जीवित जुड़वाँ के जल्दी जन्म का संकेत क्या होगा?
A. Evidence of fetal distress, abnormal Dopplers, maternal sepsis or coagulopathy
B. Parental anxiety alone without clinical abnormality
C. Change in maternal eye color
D. None — always wait until term

B. Rare but possible, especially with prolonged retention, infection or large dead fetus
C. Impossible
D. Only occurs after 42 weeks

10. Key counseling point for parents after single FDIU in stuck twin syndrome is: 10. स्टक ट्विन सिंड्रोम में सिंगल FDIU के बाद माता‑पिता के लिए प्रमुख परामर्श क्या है?
A. There is no risk to the surviving twin and no monitoring needed
B. Explain increased risk of neurological injury and preterm delivery (especially if monochorionic); outline close surveillance plan, discuss fetal MRI and neonatal care possibilities
C. Immediate termination of pregnancy is mandatory
D. No obstetric follow‑up until term
