Vascular complications, including vessel occlusion and hemorrhage, can arise after radiosurgery; however, hemorrhage due to a ruptured de novo aneurysm after Gamma Knife radiosurgery (GKS) for tumor is extremely rare. To the authors' knowledge, only a single case of de novo aneurysm formation after GKS for vestibular schwannoma has been previously reported. In this study, they describe their experience with the treatment of a 74-year-old woman with subarachnoid hemorrhage limited to the cerebellopontine cistern, who had undergone GKS for vestibular schwannoma 5 years earlier. Cerebral angiography demonstrated a left distal anterior inferior cerebellar artery aneurysm; coil embolization was attempted and failed. However, self-resolution of the aneurysm was revealed on follow-up angiography.
放射外科手术后可能会出现血管并发症，包括血管闭塞和出血；然而，伽玛刀放射外科治疗（GKS）肿瘤后因新发动脉瘤破裂导致的出血极为罕见。据作者所知，此前仅报道过1例GKS治疗前庭神经鞘瘤后新发动脉瘤形成的病例。在本研究中，他们描述了对一名74岁女性的治疗经验，该女性蛛网膜下腔出血局限于小脑脑桥池，5年前曾接受GKS治疗前庭神经鞘瘤。脑血管造影显示左小脑前下动脉远端动脉瘤；尝试进行弹簧圈栓塞但失败了。然而，随访血管造影显示动脉瘤自行消退。
