Abstract
Careful and complete removal of vascular tumors is challenging because of the brisk bleeding during operation. Preoperatively we used Gelfoam embolization of the feeding artery in juvenile angiofibroma and in paranasal capillary hemangioma. The intraoperative blood loss averaged 1045ml.
Angiography is of value to confirm the diagnosis prior to excision and to delineate the extent of the tumor. Embolization may be performed at the same sitting as preoperative treatment. Artificial embolization is described in detail, and preoperative embolization is recommended to make the surgical procedure easier in cases of vascular tumor.
