报道一例10岁男孩在行右鼓膜切开术和中耳“肿瘤”活检后发生大出血。X线断层照相术示颈动脉管异常。经股动脉颈动脉造影示双侧颈内动脉在中耳内径路变异;活检部位有假动脉瘤;前交通动脉未闭,左颈动脉注射时可见流到右大脑半球的交叉血流。将一不漏的定量漏泄的气囊与连接着的2F硅胶导管置于假动脉瘤上方右颈内动脉岩部段,阻断逆行血流。然后去手术室分离右颈内动脉。切开动脉,用小金属夹夹闭充了气的气囊导管。然后将动脉切断结扎,以便将导管固定在颈动脉内。剪断导管,将近侧部分经股动脉退出。术后
A 10-year-old boy reported bleeding after a right tympanotomy and a “tumor” biopsy of the middle ear. X-ray tomography showed abnormalities of the carotid artery. The femoral artery carotid artery angiography showed bilateral internal carotid artery in the middle ear pathways variation; biopsy sites have false aneurysms; anterior communicating artery patent, the left carotid artery can be seen flowed into the right hemisphere of the cross cerebral blood flow. A leaky, quantitatively leaked balloon and a connected 2F silicone catheter were placed over the section of the right internal carotid artery above the false aneurysm to block the retrograde flow. Then go to the operating room to separate the right internal carotid artery. Cut the artery and clamp the inflated balloon catheter with a small metal clip. The artery was then ligated to fix the catheter in the carotid artery. Cut the catheter, the proximal part of the femoral artery exit. After surgery
