Control del embarazo y manejo intraparto en la enfermedad de McArdle

We describe the pregnancy course and labor in a woman with myophosphorylase deficiency (McArdle's disease or glycogen storage disease type V). McArdle's disease is an uncommon hereditary disorder characterized by symptoms of muscular fatigue and pain, as well as by muscle cramps during heavy and continuos exercise. We feared that the increase in muscular effort during labor might complicate delivery, necessitating cesarean section.
