We retrospectively analyzed the clinical data of 21 patients (22 procedures) with histologically proven nasopharyngeal angiofibromas. Eleven patients underwent preoperative intra-arterial digital subtraction angiography (IADSA) and embolization with Gelfoam. Embolization reduced the intraoperative blood loss from an average of 1136 ml in the non-embolized patients to 677 ml in the embolized cases (P < 0.05) and transfusions from an average of 836 ml to 400 ml (P < 0.01). Results again show that preoperative embolization is effective in reducing intraoperative blood loss.
我们回顾性分析了21例（22次手术）经组织学证实为鼻咽血管纤维瘤患者的临床资料。11例患者术前行动脉内数字减影血管造影（IADSA）并使用明胶海绵栓塞。栓塞使术中失血量从未栓塞患者的平均1136 ml减少至栓塞患者的677 ml（P < 0.05），输血量从平均836 ml减少至400 ml（P < 0.01）。结果再次表明，术前栓塞在减少术中失血量方面是有效的。
