顽固性鼻衄指后鼻道填塞不能止血,须进一步处理者。从1988年～1990年用血管造影和血管内法治疗30例。其中,男21例,女9例,年龄28～83岁,平均62岁。除两例用全麻外,余均用安定止痛法。各例均经股动脉途径,皮肤用硝酸甘油,插管前不取前后鼻道填塞物。用5F导管插入鼻衄侧颈外动脉,先行血管造影,一旦确定颈外动脉无血管异常,就将一硬度可变导管插入上颌动脉的翼突腭段,作血管造影看其与颈内动脉或眼动脉有无大的交通。然后用切碎的明胶海绵混合50%盐水和50%造影剂栓塞上颌动脉翼突腭段。栓塞的进程用透视和对照血管造影监控。完成本期栓塞后,再通过该导管向上颌动脉终端送入几块较大的明胶
Stubborn epistaxis after nasal packing can not stop bleeding, to be further processed. From 1988 to 1990 with angiography and endovascular treatment of 30 cases. Among them, 21 males and 9 females, aged 28 to 83 years, mean 62 years. In addition to two cases of general anesthesia, I have used analgesic stability method. All cases were via the femoral artery, the skin with nitroglycerin, before and after intubation take nasal packing. 5F catheter inserted into the epistaxis side of the external carotid artery, angiography, once identified without external carotid artery vascular abnormalities, it will be a variable hardness catheter inserted into the maxillary artery of the wing palate, angiography to see it with the internal carotid artery or Eye artery with or without big traffic. The maxillary artery was then embolized with 50% saline and 50% contrast medium with chopped gelatin sponge. Embolization was monitored by fluoroscopy and contrast angiography. After the completion of the current embolism, and then through the catheter to the maxillary artery terminal into a few larger gelatin
