The paper presents the preliminary experience with digital subtraction angiography (DSA) in otorhinolaryngology. This series included racemose hemangioma of the auricle in 3 cases, juvenile angiofibroma of nasopharynx in 4 cases, angioma in the retropharyngeal space in 1 case, tympanic body tumor in 1 case, traumatic epistaxis in 1 case, traumatic pseudoaneurysm in 1 case. The site, supply arteries, drainage veins of vascular tumors were shown with DSA. The intraoperative bleeding was reduced significantly by preoperative embolization of supply arteries to vascular tumors. The broken arteries of the traumatic epistaxis and the traumatic pseudoaneurysm were not only discovered but embolized. The indications and complications of DSA and measures for preventing and reducing complications were discussed.
本文介绍了数字减影血管造影（DSA）在耳鼻咽喉科的初步应用经验。该系列包括3例耳廓蔓状血管瘤、4例鼻咽部青少年血管纤维瘤、1例咽后间隙血管瘤、1例鼓室体瘤、1例创伤性鼻出血、1例创伤性假性动脉瘤。DSA显示了血管肿瘤的部位、供血动脉和引流静脉。通过术前对血管肿瘤的供血动脉进行栓塞，术中出血明显减少。不仅发现了创伤性鼻出血和创伤性假性动脉瘤的破裂动脉，还对其进行了栓塞。讨论了DSA的适应证、并发症以及预防和减少并发症的措施。
