Carotid occlusion is a therapeutic intervention for specific intracranial vascular conditions, including giant, traumatic and intracavernous aneurysms. The long-term complications include de novo aneurysm formation at a distant site due to hemodynamic changes in the circle of Willis. The time frame for de novo aneurysm formation has been described in years with a mean of 9.6 years. There is no formalised radiological surveillance program following carotid occlusion. We describe the rapid development of a de novo posterior communicating artery aneurysm following contralateral carotid occlusion for a traumatic intracavernous aneurysm and suggest the need for a formalised radiological follow-up program following carotid occlusion.
颈动脉闭塞是针对特定颅内血管疾病的一种治疗干预措施，包括巨大动脉瘤、创伤性动脉瘤和海绵窦内动脉瘤。其长期并发症包括由于 Willis 环血流动力学改变导致远处部位形成新生动脉瘤。新生动脉瘤形成的时间框架以年为单位描述，平均为 9.6 年。目前尚无颈动脉闭塞后的规范化影像学监测方案。我们描述了一例因创伤性海绵窦内动脉瘤行对侧颈动脉闭塞后，后交通动脉新生动脉瘤的快速形成，并建议在颈动脉闭塞后需要有规范化的影像学随访方案。
