[The ordeal of perinatal bereavement : what roles for the liaison psychiatrist ?].

Perinatal grief should be given special attention for bereaved parents. In the hospital, multidisciplinary support is provided at different times of care. The loss of a pregnancy or a baby can permanently destabilize the couple's relationship and give rise to psychiatric complications in the presence of risk factors, such as pathological bereavement, a major depressive disorder, an anxiety disorder or a post-traumatic stress disorder. For subsequent pregnancies, there are risks of developing antenatal anxiety, attachment disorder, or parenting disorder. Multidisciplinary support and personalized psychotherapeutic and psychiatric care provided by liaison psychiatry when indicated, aim to reduce these risks.
