作者们在5年内对15例搏动性耳鸣患者进行了选择性的血管造影检查,12例获得阳性结果。其中颈静脉球体瘤3例,动静脉畸形8例,颈外动脉狭窄1例,另3例检查结果阴性。血管造影是经股动脉或经颈动脉插入内径为1.1～1.4 mm的导管、10例用60％Isopaque Cerebral(Nyegaard),5例用Amipaque(Nyegaard)。栓塞物用可吸收性明胶海绵,将海绵剪成1×1×8mm小条,放在装有盐水的针头内,注入前后,立即注射对比剂,使在萤光屏下观察导管头的位置及效果。使用海绵小条的数目,按
In five years, the authors performed a selective angiographic examination of 15 patients with pulsatile tinnitus and 12 had positive results. Among them, 3 cases were jugular bulb tumor, 8 cases were arteriovenous malformation, 1 case was external carotid artery stenosis, and the other 3 cases were negative. Angiography was performed via a femoral artery or carotid artery with a 1.1-1.4 mm ID catheter, 60% Isopaque Cerebral (Nyegaard) in 10 cases and Amipaque (Nyegaard) in 5 cases. Embolization with absorbent gelatin sponge, the sponge cut into 1 × 1 × 8mm strip, placed in a saline needle, before and after injection of contrast agent, so that under the fluorescent screen to observe the location of the catheter head and effect. Use the number of sponge strips, press
