Abstract
Acute idiopathic thrombocytopenic purpura (AITP) is a condition caused as a result of platelet aggregation due to antiplatelet antibodies, which transport platelets into the reticuloendothelial system. An 81-year-old female was diagnosed with AITP with nasal bleeding after endoscopic sinus surgery (ESS). No abnormal findings were seen in the preoperative testing and the previous history in this case, so the invasive surgery and treatment were examined as the cause of the decrease in platelets. A variety of treatment methods were examined to ameliorate the AIPT, and this case was successfully treated with a steroid and gamma globulin. As a result, the treatment response was excellent.
