title: [CMV infection: when should medical termination of pregnancy be discussed?].
abstract: OBJECTIVE
  To determine in which circumstances termination of pregnancy (TOP) could be proposed in case of CMV infection.
  
  
  METHODS
  An inquiry was conducted concerning the practice of doctors working in French foetal medicine units in case of CMV infection. The question asked was: "What is your attitude if confronted to a CMV seroconversion at 23 weeks of amenorrhoea with positive PCR at 28 WA, and normal MRI and ultrasound scan at third trimester?"
  
  
  RESULTS
  Thirty-five obstetricians answered. Forty-nine percent do not perform foetal blood sampling (FBS). Among them 1/17 would accept TOP. Fifty-one percent do perform FBS. In this group, 33% would accept TOP in case of negative FBS and 83% if FBS shows foetal infection.
  
  
  CONCLUSIONS
  Techniques available for diagnosis and prognosis of foetal infections are based on PCR on amniotic fluid, ultrasound, MRI and FBS. To date correlation of those tests with foetal outcome has not been fully validated. TOP could therefore be an option in 2 circumstances: when signs of certain severe foetal disease with positive PCR and ultrasound abnormalities; on statistical arguments: if positive PCR, and normal ultrasound, the risk of handicap is approximately 10%, the severity of the handicap being impossible to predict. In this last hypothesis, it is tempting to use additional arguments such as FBS even if the interpretation of the results of this test has not been scientifically validated. Such cases with positive PCR and normal ultrasound in which inconsistent decisions are made are likely to be more frequent because of routine serologic screening policy.
