作者以选择性颌内动脉栓塞术治疗难制止的鼻腔后部出血5例:其中3例按Seldinger 氏法自右股动脉插管,管径6.5F;高龄者2例,70～75岁,考虑有动脉硬化而自颈总动脉插管,管径5F。均先做出血侧颈外动脉造影,然后将导管送入颌内动脉。在透视下将小片明胶海绵约1×2×5mm 混于造影剂中,作颌内动脉造影的同时将之栓塞。有出血性素质、造影剂过敏、严重高血压或肾功能不良者禁用。本组5例原因不明特发性鼻出血经血管栓塞后观察2～9个月,无一例再出血。本法无需外科手术,颈外动脉造影尚可发现异常血管找到出血点。上颌窦术后、上颌窦发育不良者作颌内动脉结扎有困难,采用本法则简便有效。但将导管插入颌内动脉需专门训练。合并症有面神经部分麻痹、牙关紧闭、面部疼痛
The author of selective intra-artery embolization in the treatment of refractory nasal hemorrhage in 5 cases: 3 cases by Seldinger’s method from the right femoral artery, diameter 6.5F; elderly 2 cases, 70 to 75 years old, consider Atherosclerosis from the common carotid artery, diameter 5F. First make a blood-based external carotid artery angiography, and then the catheter into the maxillary artery. In the perspective of a small piece of gelatin sponge about 1 × 2 × 5mm mixed with contrast agent for the same time as the maxillary artery embolization embolization. Hemorrhagic quality, contrast agent allergy, severe hypertension or renal dysfunction disabled. This group of 5 patients with unexplained idiopathic epistaxis observed after embolism 2 to 9 months, no case of rebleeding. This law without surgery, external carotid angiography can still find abnormal blood vessels to find the bleeding point. Maxillary sinus surgery, maxillary sinus dysplasia for the ligation of the internal carotid artery has difficulty, the use of this rule is simple and effective. However, the catheter into the internal carotid artery should be specialized training. Complications of facial nerve paralysis, teeth closed, facial pain
