介入放射学在颈静脉球瘤术前应用的价值

目的:评价介入放射学在颈静脉球瘤术前应用的价值.方法:本组9例颈静脉瘤患者均经手术病理证实,所有患者于术前行双侧颈内、外动脉和椎动脉造影检查,对其中7例患者行术前供血动脉栓塞及患侧颈内动脉球囊阻断试验以了解Willis'环功能.结果:9例颈静脉球瘤患者术前造影及7例供血动脉栓塞均获成功,肿瘤切除术中出血明显减少;6例通过颈内动脉球囊阻断试验,术中施行颈内动脉结扎术,术后随访均未出现神经系统症状或体征.结论:颈静脉球瘤术前供血动脉栓塞及颈内动脉球囊阻断试验是安全可靠的,可作为常规术前检查.

Clinical Value of Interventional Radiology for Jugular Paragangliomas

Objective:To evaluate the value of pre-operative interventional managements for jugular paragangliomas.Methods:9 surgically and pathologically proven cases of jugular paragangliomas were retrospectively studied.In all the 9 cases,DSA of both internal and external jugular veins as well as vertebral arteries were performed.For checking the functions of Willis circle,embolization of the feeding artery and internal carotid artery(ICA) balloon occlusive test were undergone in 7 of the 9 cases.Results:The pre-operative DSA for showing the angiographic features of the tumors in all the 9 cases and the interventional procedures of embolizing the feeding arteries of the tumors in the 7 cases were all successfully performed.In the excision of the tumors,remarkably less bleeding happened.In the 6 patients who had passed the carotid artery balloon occlusive tests,the operation of carotid artery ligation was engaged.In these 6 patients,symptoms and signs of the nervous system had not been found in the follow-up observation.Conclusion:The preoperative interventional procedures of tumor feeding artery embolization and balloon occlusive test of ICA were proved to be reliable and safe,therefore,they might be recommended as regular pre-operative examinations in the cases of jugular paragangliomas.
