颅底富血供肿瘤术前超选择性颈外动脉插管栓塞9例报告

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。

The preoperative application of selective catheterization and embolism of the external carotid artery in treating tumors with enriched blood supply in the base of skull

Objective:Embolizing the feeding vessels of the tumors with enriched blood supply in the base of skull in order to reduce the bleeding during operation.Method:Under digital subtraction angiographic control,superselectively catheterizing the external carotid artery,thus occluding the terminal branches of the feeding arteries of the tumor with particles of liquidized gelfoam.Result:Nine cases studied showed that the angiograh of the feeding vessels of the tumor disappeared relatively.The bleeding decreased significantly during operation.The postoperative pathological findings showed that the entity of the tumor was congested with gelfoam.Conclusion:After figuring out the blood supply of the tumor,superselective catheterization of the external carotid artery followed by occlusion of the feeding vessels can reduce the size of the tumor and diminish the bleeding during operation,thus can improve the safety of the operation.It should be one of the crucial preoperation measures.
