【摘要】 目的:探讨严重鼻出血的选择性血管造影诊断和超选择性血管栓塞治疗。方法:用Seldinger技术经股动脉穿刺,送入5FCobra导管,入颈总动脉,行选择性血管造影,对出血血管进行分析、诊断,采用直径为140～250μm的真丝线段超选择性栓塞出血血管。结果:全部病例止血效果确切,术后随访2月～1年无复发,8例患者1周内行耳鼻喉手术,均明显减少了术中出血,降低了手术难度,提高了手术成功率。结论:本组资料表明:选择性血管造影的诊断,超选择性的栓塞治疗,相应大小的栓塞物质和颗粒,适当的栓塞速度是成功的关键。上颌动脉栓塞治疗是一种安全、有效、简便的止血与治疗方法,并为耳鼻喉的部分手术开辟了良好的新途径。更多还原

【Abstract】 Objective To evaluate selective angiographic diagnosis and superselective embolization of intractable epistaxis in 21cases.Methods The seldinger technique was used in a ll patients.The catheter was introd uced via femoral artery on the right side.Selective angiographic analysis and di agnosis were performed.Superselective an-giographic embolization with silk t hread in diamend form 140to 250um was performed in bleeding vessels.Results All cases achieved satisfactory effect.During the follow -up 2to 12mont h,no patients recurrence nose bleed ing.8cases were operated in 1week.Bleedi ng reduced sharply in operation,and difficulty of operation cut down and success rate of operation was increa sed.Conclusions Selective angiographic diagnosis,and Superselective angio-graphic embolization,and suitive s ilk thread granular,and appropriate embolic speed is critical for successful treat-ment of massive epistais,Maxillary artery embolization is safe,effective,and uncomplicated Interventio nal em-bolization has afforded a new methed for acoustic -nasola -larynxologic operation.更多还原
