Abstract
We retrospectively analyzed the clinical data of 21 patients (22 proce dures) with histologically proven nasopharyngeal angiofibromas. Eleven patients underwent preoperative intra-arterial digital subtraction an giography (IADSA) and embolization with Gelfoam. Embolization reduced the intraoperative blood loss from an average of 1136 mi in the non-em bolized patients to 677 mi in the embolized cases (P < 0.05) and trans fusions from an average of 836 mi to 400 mi (P < 0.01). Results again show that preoperative embolization is effective in reducing intraoper ative blood loss.
