Am I a candidate for fetal therapy? How eligibility is assessed

Eligibility for fetal therapy is not determined by the name of a condition alone. It is a structured judgement about whether a particular procedure is technically possible, supported by evidence for that stage and severity, acceptable for the mother, and likely to offer more benefit than the alternatives.

Diagnostic criteria

The diagnosis must be sufficiently secure. Expert ultrasound may change an outside label, identify associated abnormalities, or show that the disease is less or more advanced than first thought. Genetic and infection testing can alter prognosis and the expected value of treatment.

Severity and timing

Many fetal conditions have a spectrum. Mild disease may be safer to monitor, while advanced disease may have already caused irreversible injury. Gestational age can determine whether intervention, delivery, or postnatal treatment is the realistic option. Some procedures have narrow windows because anatomy, membrane risk, or evidence changes as pregnancy advances.

Maternal and technical factors

Maternal health, anaesthetic considerations, previous surgery, placental position, fetal position, cervical length, membrane status, uterine anatomy, and accessibility of the target all matter. A technically possible procedure is not necessarily clinically advisable.

Outcomes that matter

Counselling should not focus only on survival. It should address the chance of reaching a later gestation, neurological or organ function, maternal complications, repeat procedures, preterm birth, mode and place of delivery, neonatal surgery or intensive care, and longer-term uncertainty.

The comparison is between complete pathways:

• continued surveillance with defined escalation criteria;
• prenatal intervention plus its maternal and pregnancy risks;
• planned early delivery and neonatal treatment;
• postnatal treatment at term where safe;
• or comfort-focused care when the condition is not treatable and the prognosis is very poor.

A second opinion

A second opinion is reasonable when the diagnosis is uncertain, the condition is rare, the proposed procedure is high risk, or the family needs a clearer explanation of alternatives. Send original imaging rather than only written summaries. The purpose is to improve the decision, not to guarantee access to a procedure.

The dated programme-status panel gives the current classification and qualification for fetal transfusion, TTTS laser, FETO, and fetoscopic spina-bifida assessment. No programme status replaces individual eligibility, governance, or informed consent.
