头颈部高血运肿瘤术前栓塞

目的 探讨头颈部高血运肿瘤术前栓塞的作用和适应征。方法 采用经皮穿刺插管选择性全脑血管造影和颈外肿瘤供血动脉术前３￣５天血管内栓塞２３０例，所用栓塞材料为自制明胶海绵微粒，３．６￣５Ｆ造影导管，２ｍｌ注射器不断注入造影剂观察，直至肿瘤血管染色消失，。结果 栓塞后肿瘤手术出血明显减少，平均每例手术输血量减少１／３。栓塞后无永久性并发症发生。结论 头颈部高血运肿瘤手术切除前均应争取全脑血管造影，肿瘤供

Preoperative Embolization Therapy for Hypervascular Tumors in Head- Neck

Objective To evaluate the effect and indication of preoperative embolization in the treatment of head-neck hy-pervascular tumors. Method Data of 230 patients with hypervascular head-neck tumors, who received cerebral angiography and subsequently underwent selective cathetering embolization, were retrospectively analyzed. Results The average blood loss of patients , in whom the supplying arteries of the trmor had been embolized 3-5 days before operation, was significandy reduced than those in the patients who were not embolized. There were no permanent compcications after operation in this series of patients. Conclusions The authors concluded that angiography should be carried out as often as possible in patients with hypervascular tumors in the head-neck region and the preoperative embolization can not only minimize blood loss during surgery, but also facibtate complete removal of the tumor.
