摘要： 目的 探讨颅骨数字减影在颅内动脉瘤血管内治疗术后随访中的应用。方法 共43 例颅内动脉瘤患者行血管内弹簧圈栓塞或弹簧圈栓塞辅助支架成形术，术后3 个月行正侧位颅骨数字减影和全脑血管造影术，观察弹簧圈位置、形态及动脉瘤是否复发。结果 43 例患者中前交通动脉动脉瘤14 例、后交通动脉动脉瘤17 例、大脑中动脉动脉瘤5 例、基底动脉尖端动脉瘤5 例和小脑后下动脉动脉瘤2 例。术后3 个月时，颅骨数字减影与全脑血管造影术检查一致性约为97.67%（42/43），所显示复发率分别为2.33%（1/43）和4.65%（2/43），两种检查方法术后随访准确度差异无统计学意义（χ² = 0.345，P = 0.955）。结论 颅骨数字减影用于颅内动脉瘤血管内治疗术后随访的准确度较高且安全有效。

Abstract: Objective  To investigate the application of skull digital radiography (DR) during the follow-up after endovascular treatment of intracranial aneurysms.  Methods  Forty-three patients with intracranial aneurysms underwent endovascular coil embolization or stent angioplasty assisted by coil embolization. Three months later, they underwent skull DR and digital subtraction angiography (DSA) to observe the location and morphology of coils and whether there was recurrence of aneurysms. Results  Among 43 patients, there were 14 cases of anterior communicating artery aneurysms, 17 cases of posterior communicating artery aneurysms, 5 cases of middle cerebral artery aneurysms, 5 cases of basilar artery aneurysms and 2 cases of posterior inferior cerebellar artery aneurysms. The coincidence of skull DR and DSA in detecting the form of coils was about 97.67% (42/43). DSA found 2 cases had recurrence, while skull DR found only one case with recurrence. There was no statistical difference between the two methods (χ² = 0.345, P = 0.955).  Conclusions  Skull digital radiography is a safe and effective method with high accuracy in the follow-up examination after endovascular treatment of aneurysms.
