McArdle disease or glycogen storage disease (GSD) type V is a rare autosomal recessive inherited disorder in skeletal muscle metabolism leading to exercise intolerance, muscle cramps and in some cases to rhabdomyolysis and acute renal failure due to elevated serum myoglobin levels. Albeit the uterine smooth muscle is not affected, pregnancy and delivery can be physically strenuous and may require specific anesthesiologic care. However, data on pregnancy progress and outcome and on special implications linked to anesthesia in women with McArdle's disease is scarce, thus posing a challenge to pre- and peripartal management. We report a case of a pregnant woman with Morbus McArdle who was monitored during her pregnancy and delivered a healthy male via cesarean section under spinal anesthesia. Pregnancy, delivery and recovery were uneventful. Our findings, combined with a literature review, lead to the conclusion that uncomplicated pregnancy and delivery can be expected.
