[Myasthenia gravis and pregnancy: review of the literature and report of 2 cases].

Two cases of women with myasthenia gravis are presented. These women had three pregnancies followed by the authors, and description is made of clinical follow-up, therapeutic complications, termination of pregnancy, puerperal and perinatal outcome. A review of the literature is made due to the rarity of this condition and emphasis is given to the specialized knowledge required to adequately manage these cases. Myasthenia gravis, when associated to pregnancy, presents aspects that make it a high risk disease, decompensations of myasthenia being more common. Aspects relative to diagnosis and therapy of myasthenia in pregnancy and in the newly-born are reviewed, and considerations about anesthesia in the myasthenic pregnant woman.
