Bleeding during mastoidectomy usually occurs because of injury to the dura mater and/or sigmoid sinus, which, in most cases, can be controlled easily. The other important cause is damage to the internal carotid artery during its course in the middle ear. Bleeding from the external carotid artery or a branch of it is very rare and unknown. We hereby report an extremely rare and first case of delayed torrential bleeding after modified radical mastoidectomy, which was because of infective necrosis and subsequent blowout of the anterior tympanic branch of superficial temporal artery and its management using microcoils via an endovascular approach.
乳突切除术中的出血通常是由于硬脑膜和/或乙状窦损伤引起的，在大多数情况下，这些损伤很容易控制。另一个重要的原因是颈内动脉在中耳内走行时受损。来自颈外动脉或其分支的出血非常罕见且未知。我们在此报告一例极为罕见的改良根治性乳突切除术后迟发性大出血的首例病例，其原因是感染性坏死和随后的颞浅动脉前支破裂，并通过血管内途径使用微线圈进行治疗。
