目的:探讨瘤夹打磨技术在颅内动脉瘤锁孔入路显微手术中的应用价值和操作技巧。方法:回顾性分析苏州大学附属第二医院神经外科2017年1月至2019年12月经锁孔入路显微手术治疗的颅内动脉瘤患者的临床资料，其中27例在手术中采用瘤夹打磨技术进行个体化瘤夹重塑。手术后1周内复查脑血管造影，评估瘤夹的位置和动脉瘤的夹闭情况。所有患者门诊随访，评估临床预后。结果:27例患者共有30个颅内动脉瘤；其中破裂动脉瘤23个，未破裂动脉瘤7个。大脑中动脉瘤9个，前交通动脉瘤11个，后交通动脉瘤9个，大脑前动脉瘤1个。经眶上锁孔入路手术9例，经翼点锁孔入路手术17例，经半球间锁孔入路1例。手术后复查脑血管造影显示均夹闭满意，无明显动脉瘤残留。出院时恢复良好25例，轻度残疾2例。随访3~36个月，均无再出血和新发神经功能障碍。结论:瘤夹打磨技术简单、有效，可弥补锁孔入路下手术自由度的限制，提高颅内动脉瘤的显微手术治疗效果。“,”Objective:To discuss the value and technique of clip remodeling in microsurgical treatment of intracranial aneurysms via keyhole approaches.Methods:The clinical data of patients with intracranial aneurysms, who were treated by microsurgical clipping via keyhole approaches from January 2017 to December 2019, were retrospectively analyzed. The clips were remodeled based on the aneurysmal characteristics during the procedure in 27 cases. Angiography was obtained within one week after surgery in order to evaluate the position of clips and the security of lesions. All patients were followed up at the outpatient clinic to assess the clinical outcomes.Results:A total of 27 patients harbored 30 intracranial aneurysms, including 23 ruptured lesions and 7 unruptured ones. There were 9 middle cerebral artery aneurysms, 11 anterior communicating artery aneurysms, 9 posterior communicating artery aneurysms and 1 anterior cerebral artery aneurysm, respectively. Nine patients were operated via supraorbital keyhole approach, as well as 17 via pterional keyhole approach and one via hemispheric keyhole approach. Postoperative angiography revealed complete obliteration of lesions without residual filling in all cases. Twenty-five patients recovered well at discharge and two presented with mild disability. After 3-36 months of follow-up, no rebleeding and new-onset neurological deficits were noted.Conclusion:Clip remodeling technique is a simple and effective option, which can alleviate the limitation of manipulative freedom under keyhole approaches and improve the microsurgical effect of intracranial aneurysms.
