目的：观察数字减影血管造影（ Ｄ Ｓ Ａ）及栓塞在鼻咽纤维血管瘤外科中的应用。方法：对１２例鼻咽纤维血管瘤患者术前行 Ｄ Ｓ Ａ 检查，同时对供应血管进行栓塞。结果：栓塞后３～５ ｄ 进行肿瘤切除，收到了术中出血少、术野清楚的效果，给彻底切除肿瘤创造了条件。结论： Ｄ Ｓ Ａ 及栓塞术在鼻咽纤维血管瘤外科有广泛的应用前景，同时也适用于耳鼻咽喉科其他种类出血性疾病。
Objective: To observe the application of digital subtraction angiography (D S A) and embolization in the surgical treatment of nasopharyngeal hemangioma. Methods: Twelve patients with nasopharyngeal fibroadenoma underwent preoperative DSA examination and embolization of the supplying blood vessels. Results: Three to five days after embolization, tumor resection was performed, and less bleeding was found and the operative field was clear, which provided the conditions for radical resection of the tumor. CONCLUSIONS: DSA and embolization are widely used in the surgical treatment of nasopharyngeal hemangiomas and are also suitable for other hemorrhagic diseases of otolaryngology.
