Beyond the enhanced miscarriage and prematurity associated with the structurally abnormal uterus, we have found 14 examples of fetal deformation secondary to uterine malformation with its consequent uterine constraint. In several instances the constellation of deformations had been misinterpreted as a multiple malformation disorder. One patient died of pulmonary hypoplasia, but all the survivors showed restoration toward normal form postnatally. Recognition of the basic problem allows for surgical reconstruction of the uterus, which is generally accompanied by an improved outlook for subsequent pregnancies.
