Embolization was performed in two cases of angioma in the nasal cavity prior to surgery in order to minimize the amount of bleeding. In case 1, the injected embolizing substance (Ivalon) was insufficient, because the amount of bleeding during surgery was as much as 500 ml. Higher dosage of injected substance, however, sometimes leads to less bleeding and higher risk of complication. Since the optimum amount of injected substance has not been discussed further investigation of the standard injectable level should be carried out. In case 2, the amount of bleeding was very little. Thus, embolization is useful as a method of peroperative blood loss prophylaxis in some cases.
