目的:分析颈静脉球瘤的DSA表现,评价栓塞治疗的作用。材料和方法:患者5例(男性3例,女性2例)。采用Seldinger技术,行超选择性动脉插管并造影;栓塞剂采用明胶海绵颗粒和/或真丝线段,分次缓慢注入栓塞材料,栓塞过程中监测肿瘤血管及供血动脉闭塞情况。结果:5例颈静脉球瘤。DSA动脉期表现为颈静脉孔、乳突区或后颅凹大片血管团块影,其间血管婉蜒迂曲,颈外动脉之咽升动脉、耳后动脉、枕动脉为主要供血动脉,颈内动脉脑膜垂体干、椎动脉之脑膜支、小脑后、前动脉可参与供血。实质期肿瘤呈湖状、巢状染色。静脉期2例肿瘤较大者见粗大的引流静脉丛向下引流至颈内静脉。栓塞后肿瘤的供血动脉大多被栓塞,肿瘤染色明显减少或消失。栓塞术后7天内行手术,肿瘤完全或大部分切除。结论:DSA是显示颈静脉球瘤供血动脉的最佳方法,根据DSA表现,可以准确确定肿瘤的位置和侵犯范围。术前栓塞为手术切除提供了良好条件。
Objective: To analyze the DSA appearance of jugular bulb tumors and evaluate the effect of embolization therapy. Materials and Methods: Five patients (3 males and 2 females). Seldinger technique was used to perform superselective arterial intubation and angiography. Gel plug particles and/or silk segments were used as embolic agents. The embolic material was slowly injected in several fractions. During the embolization process, tumor blood vessels and blood supply artery occlusion were monitored. Results: 5 cases of jugular glomus tumors. The DSA arterial phase shows a large vascular mass in the jugular foramina, mastoid region, or posterior fossa. The vasoconstriction occurs during this period. The pharyngeal ascending artery, posterior auricular artery, and occipital artery of the external carotid artery are the main blood supply arteries and the internal carotid artery. The meningeal pituitary, the meningeal branch of the vertebral artery, the posterior cerebellum, and the anterior artery may participate in blood supply. The parenchymal tumors were stained in lakes and nests. In the venous phase, 2 patients with larger tumors were found to have large drainage veins draining down to the internal jugular vein. After embolization, the blood supply artery of the tumor was mostly embolized, and the tumor staining was significantly reduced or disappeared. The operation was performed within 7 days after embolization, and the tumor was completely or mostly resected. Conclusion: DSA is the best way to display the arteries of the jugular bulbocele. According to the DSA findings, the location and range of the tumor can be accurately determined. Preoperative embolization provides good conditions for surgical resection.
