Idiopathic thrombocytopenic purpura is an autoimmune disorder characterized by a low platelet count. Onset usually occurs during adolescence with episodes of cutaneous and mucosal bleeding. Thrombocytopenia during pregnancy is associated with many diseases, of which idiopathic thrombocytopenic purpura is the most common in the first trimester. The need for treatment will depend on the platelet count and whether there is bleeding. At the end of pregnancy, however, whether delivery is vaginal or by cesarean, more aggressive therapeutic measures are required. Anesthetic management in this type of patient will be determined by coagulation status and platelet count, and local or regional anesthesia may be contraindicated. We report the case of a pregnant woman with idiopathic thrombocytopenic purpura who was admitted to the emergency department of our hospital with suspected preeclampsia.
