[Prenatal Diagnostics and Postnatal Complications in a Case of Extremely Rare Tetra-Amelia].

Tetra-amelia is extremely rare with an incidence of 2.4 per 10,000,000 births. It describes the absence of all 4 outer extremities and can be associated with other malformations. The boy presented here was diagnosed at 22 1/7 weeks of gestation by sonography in 2D and 3D mode. The parents decided to continue the pregnancy; vaginal birth occurred after external rotation at 38 1/7 weeks of pregnancy. Postnatally, surgical closure of a cleft of the soft palate was performed. External abnormalities manifested themselves increasingly in the area of the spine and the face. The anatomically limited psychomotor development of the child is supported by physiotherapy, occupational therapy, and speech therapy. Various aids enable the child to participate in activities appropriate to his age.
