目的 :探讨数字减影血管造影 (DSA)在耳鼻咽喉科疾病诊治中的应用前景。方法 :回顾性分析我科 1995年 11月至1999年 12月应用 DSA诊治严重鼻出血 10例、鼻咽纤维血管瘤 3例、咽部及咽旁间隙占位性病变各 1例的诊断和治疗情况。结果 :10例严重鼻出血中 9例在 DSA下行血管栓塞治疗 ,8例成功 ,有效率为 88.89% ;3例鼻咽纤维血管瘤术前栓塞肿瘤供血动脉均获成功 ,减少了术中出血量 ;2例占位性病变经 DSA得以明确诊断。所有行 DSA的患者均未发生严重并发症。 结论 :DSA不仅是诊断和治疗严重鼻出血的安全、有效的方法 ,且能对占位性病变作鉴别诊断。术前选择性栓塞瘤体供血动脉 ,能有效地减少术中出血量。
Objective: To explore the application prospect of digital subtraction angiography (DSA) in the diagnosis and treatment of otorhinolaryngology diseases. Methods: A retrospective analysis of our department from November 1995 to December 1999 DSA diagnosis and treatment of severe nasal bleeding in 10 cases, 3 cases of nasopharyngeal hemangiomas, pharyngeal and parapharyngeal space-occupying lesions in 1 case of diagnosis and treatment Happening. Results: Nine of 10 cases of severe epistaxis were treated by DSA with vascular embolization, and 8 cases were successful, with an effective rate of 88.89%. Three cases of preoperative embolization of tumor-supplying artery of nasopharyngeal fibroadenoma were successfully treated, which reduced the intraoperative blood loss Two cases of space-occupying lesions were confirmed by DSA. None of the patients in DSA had any serious complications. Conclusion: DSA is not only a safe and effective method for diagnosis and treatment of severe epistaxis, but also can make a differential diagnosis of mass lesions. Preoperative selective embolization of the donor artery, can effectively reduce the amount of intraoperative bleeding.
