外伤性动脉瘤罕见,仅占颅内动脉瘤总数的0.15％～0.40％,早期诊断比较困难。作者通过分析12例颅内颈动脉分支部外伤性动脉瘤患者的临床表现、CT扫描结果、栓塞前后脑血管造影结果及随诊情况,阐明了在钝性颅脑损伤中,脑血管造影检查的必要性、时机及治疗方法的选择。研究结果表明,12例外伤性动脉瘤患者中,11例位于颅底,1例位于大脑前动脉远端。7例位于颈内动脉海绵窦段者,CT扫描均显示蝶窦侧壁骨折及蝶窦内血肿。其中6例(89％)出现鼻
Traumatic aneurysms are rare, accounting for only 0.15% to 0.40% of the total number of intracranial aneurysms, early diagnosis is more difficult. By analyzing the clinical manifestations, CT scan results, cerebral angiography before and after embolization and the follow-up of 12 patients with traumatic aneurysm in the branch of craniocerebral carotid artery, the author elucidated the significance of cerebral angiography in blunt traumatic brain injury Necessity, timing and treatment options. The results showed that in 12 cases of traumatic aneurysms, 11 were located in the base of the skull and 1 was located in the distal part of the anterior cerebral artery. 7 cases were located in the cavernous sinus segment of the internal carotid artery, CT scan showed sphenoid sinus wall fracture and sphenoid sinus hematoma. Six of the patients (89%) developed nasal symptoms
