Twin to Twin Transfusion Syndrome |
Procedure: Fetoscopic Selective Laser Photocoagulation |
| Study Type: | Interventional |
| Study Design: | Allocation: Randomized Endpoint Classification: Safety/Efficacy Study Intervention Model: Parallel Assignment Masking: Open Label Primary Purpose: Treatment |
| Official Title: | A Prospective, Randomized Multicenter Trial of Amnioreduction Vs Selective Fetoscopic Laser Photocoagulation for the Treatment of Severe Twin-Twin Transfusion Syndrome |
- Survival of donor twin at 30 days after birth and no treatment failure
- Survival of recipient twin at 30 days after birth and no treatment failure
- Survival times of each twin in utero or after birth (which may be censored at 30 days after birth)
- Gestational age at delivery
- Placental insufficiency
- Cardiac outcome: echocardiographic evidence of cardiac compromise
- Neurologic outcome: evidence of brain injury preceding birth by MRI
- Postnatal comorbidity
| Estimated Enrollment: | 150 |
| Study Start Date: | March 2002 |
| Estimated Study Completion Date: | May 2007 |
We hypothesize that treatment of the underlying chorioangiopagus by selective fetoscopic laser photocoagulation will not only improve the survival of twins but will reduce the incidence of neurologic, cardiac, and developmental sequelae of twin-twin transfusion syndrome (TTTS). We propose to test this hypothesis by a prospective randomized multicenter trial to compare serial amnioreduction with selective fetoscopic laser photocoagulation in cases of severe (stage II-IV) twin-twin transfusion syndrome (TTTS). Primary Outcomes: Survival of donor twin at 30 days after birth and no treatment failure; Survival of recipient twin at 30 days after birth and no treatment failure; Secondary Outcomes: Survival times of each twin in utero or after birth (which may be censored at 30 days after birth); Gestational age at delivery; Placental insufficiency; Cardiac outcome: echocardiographic evidence of cardiac compromise; Neurologic outcome: evidence of brain injury preceding birth by MRI; Postnatal comorbidity
Eligibility| Ages Eligible for Study: | 18 Years and older |
| Genders Eligible for Study: | Female |
| Accepts Healthy Volunteers: | Yes |
Inclusion Criteria:
- Both twins are alive
- TTTS diagnosed prior to 22 weeks gestation
- Monochorionic diamniotic gestation
- Like sex twins
- Single placental mass
- Thin intertwin membrane
- Oligohydramnios in donor twin (deepest vertical pocket of ≤ 2 cm)

- Decompressed bladder in donor not seen to fill during the ultrasound examination (stage II, III, or IV), unless Doppler velocimetry changes (absent end-diastolic umbilical artery flow, abnormal ductus venosus waveform), and/or echocardiographic changes (valvular insufficiency, ventricular hypertrophy) are already present
