Anesthetic management of seven deliveries in three sisters with the May-Hegglin anomaly.

May-Hegglin anomaly is a rare genetic hematological disorder characterized by thrombocytopenia, but platelet function is usually normal. Three sisters with May-Hegglin anomaly and thrombocytopenia (platelet counts 14,000-100,000/mm(3)) were given neuraxial anesthesia for a total of 7 deliveries, 5 vaginal and 2 cesarean. None of the women had complications and no blood products were transfused.
