We report an unusual case (never described) of a false aneurysm of the maxillary artery following irradiation and biopsy that ruptured into the nasopharynx in an 34-year-old man who presented with severe epistaxis 15 months after radiation therapy of the nasopharynx (80 Gy). Angiography revealed a fusiform aneurysm of the second portion of the maxillary artery, which was successfully embolized but the patient died from a pseudomonas septicemia three months later. False aneurysms of the maxillary artery following irradiation are exceptional complications. Despite a successful endovascular treatment, the absence of collateral revascularization did not allow to complete healing of the radionecrotic pharyngeal area and led to a lethal septicemia.
我们报告了一例罕见病例（此前从未有过描述）：一名34岁男性在接受鼻咽癌放疗（80 Gy）15个月后出现严重鼻出血，其在放疗及活检后发生上颌动脉假性动脉瘤并破裂入鼻咽部。血管造影显示上颌动脉第二段有一梭形动脉瘤，该动脉瘤成功栓塞，但患者三个月后死于铜绿假单胞菌败血症。放疗后发生上颌动脉假性动脉瘤是罕见的并发症。尽管血管内治疗成功，但由于缺乏侧支血管再通，放射性坏死的咽部区域未能完全愈合，导致致命的败血症。
