目的 :探讨超选择性颈外动脉插管栓塞术在颅底富血供肿瘤手术治疗中的作用。方法 :对 9例颅底富血供肿瘤患者术前先作双侧颈内、颈外及椎动脉造影后再行栓塞治疗。结果 :9例栓塞后 ,肿瘤供血网显影消失 ,术中出血量明显减少。术后病理检查 ,镜下均见瘤体微血管及血窦内充满大量明胶海绵。结论 :超选择性颈外动脉插管造影 ,在明确肿瘤血供类型后辅以术前栓塞治疗 ,既可缩小瘤体又能减少术中出血 ,是肿瘤围手术期处理的重要手段之一
Objective : To explore the role of superselective external carotid artery catheterization in the treatment of tumor-rich blood supply for tumors. Methods : Nine cases of tumors with rich blood supply to the skull base were subjected to embolization before bilateral internal and external cervical and vertebral arteriography. Results: After 9 cases of embolization, the tumor blood supply network developed and disappeared, and the amount of intraoperative blood loss was significantly reduced. Postoperative pathological examination showed that all the microvessels and sinusoids of the tumor were filled with gelatin sponges. Conclusion: Ultra-selective external carotid artery cannulation angiography, after defining the type of tumor blood supply and supplemented with preoperative embolization, can both reduce the size of the tumor and reduce intraoperative blood loss. It is one of the important means for perioperative management of tumors.
