摘　　要：目的探讨3D打印联合Smart Mask技术在小型颅内动脉瘤介入治疗中的应用价值。方法选取40例接受介入治疗的小型颅内动脉瘤患者,按照随机数表法分为观察组(n=18)与对照组(n=22),观察组利用脑血管造影资料于术前制备动脉瘤模型进行模拟手术,辅助微导管塑形,术中采用Smart Mask技术获取血管路径图,引导血管内操作。对照组采用传统方法进行介入治疗。比较两组患者微导管反复塑形的次数、末次塑形后微导管超选择置入所用时间、对比剂的使用量、X线的曝光量以及术后3个月的日常生活能力评分。结果两组患者手术均获得成功。观察组微导管塑形的次数、末次塑形后微导管超选择置入所用时间、对比剂的使用量、X线的曝光量均低于对照组,差异有统计学意义(P<0.05)。观察组患者术后3个月日常生活能力评分优于对照组,差异无统计学意义(P>0.05)。结论在小型颅内动脉瘤介入治疗中应用3D打印与Smart Mask技术可以降低患者手术风险,同时有利于患者肾功能的保护与医护人员的自我防护。Objective To investigate the application value of combining 3D printing with Smart Mask technology in the interventional treatment of small intracranial aneurysms.Methods Forty patients with small intracranial aneurysms who were scheduled to undergo interventional therapy were randomly divided into an observation group(n=18)and a control group(n=22)using a random number table.In the observation group,preoperative aneurysm models were created based on cerebrovascular angiography data,and simulated surgeries were performed to assist in the shaping of microcatheters.During the actual procedure,Smart Mask technology was employed to acquire vascular path maps,which guided the intravascular interventions.The control group received interventional treatment using conventional methods.The following parameters were compared between the two groups:the number of reshaping attempts for the microcatheter,the duration required for the final microcatheter placement after reshaping,the amount of contrast medium used,the X-ray exposure dose,and the activities of daily living(ADL)scores at 3 months following the procedure.Results The surgeries were successful for both groups.The observation group had significantly fewer microcatheter shapings,a shorter time required for microcatheter superselection following the final shaping,a lower volume of contrast medium used,and reduced X-ray exposure compared to the control group(P<0.05).The ADL scores for the observation group were higher than those for the control group three months after the operation,but the difference was not statistically significant(P>0.05).Conclusion The integration of 3D printing and Smart Mask technology in the interventional treatment of small intracranial aneurysms not only reduces surgical risks for patients but also contributes to the preservation of renal function and enhances the self-protection measures for medical personnel.
