Two cases of pregnancy with Achondroplasia

Abstract

 Two cases of pregnancy complicated with achondroplasia（ACH）are described. We performed cesarean section in both cases for cephaloplelvic disproportion. In addition, we chose general anesthesia because spinal anesthesia was difficult for thoracolumbar junction kyphosis in both cases. Case1 needed the management of the threatened premature delivery, but was able to continue the pregnancy until 36 weeks. In Case2, fetus was suspected to have ACH because of recognition of disproportionate small stature on ultrasonography. It is reported that there are various obstetric complications in ACH for its characteristic features. In those cases, vaginal delivery is difficult and choose cesarean section due to small and contracted pelvis. In the case of pregnancy with achondroplasia, it is necessary to manage carefully in facilities which can cooperate with anesteologists because there is a difficult case about the anesthesia.
