Direct surgical clipping appears to be an efficient means for managing unruptured middle cerebral artery (MCA) aneurysms, owing to several angioanatomic features. Here, we present a minimally invasive technique that uses navigation guidance for the treatment of unruptured MCA aneurysms.
Between July of 2003 and June of 2005, we used image-guidance navigation to operate on 24 patients who were diagnosed with unruptured MCA aneurysm. Five men and 19 women were included in the study, and their ages ranged from 43 to 70 years (mean, 58 yr). We predetermined the transsylvian trajectory toward the aneurysm and planned a tailored craniotomy for each patient.
All aneurysms were readily identified and successfully clipped via craniotomies of less than 3 cm in diameter. We experienced no surgical complications, and each patient had an uneventful postoperative course.
With the aid of navigation, we were able to easily locate MCA aneurysms and perform minimally invasive surgeries such as mini-craniotomies, tailored sylvian dissections, and successful clippings of unruptured MCA aneurysms. In addition, we obtained satisfactory cosmetic results.
由于一些血管解剖学特征，直接手术夹闭似乎是处理未破裂大脑中动脉（MCA）动脉瘤的有效方法。在此，我们介绍一种使用导航引导治疗未破裂MCA动脉瘤的微创技术。
在2003年7月至2005年6月期间，我们使用图像引导导航对24例被诊断为未破裂MCA动脉瘤的患者进行手术。研究纳入5名男性和19名女性，年龄范围为43至70岁（平均58岁）。我们预先确定了朝向动脉瘤的经侧裂轨迹，并为每位患者规划了定制的开颅手术。
所有动脉瘤均通过直径小于3 cm的开颅手术轻松识别并成功夹闭。我们未经历手术并发症，每位患者术后过程顺利。
借助导航，我们能够轻松定位MCA动脉瘤，并进行微创外科手术，如小型开颅手术、定制的侧裂解剖以及成功夹闭未破裂的MCA动脉瘤。此外，我们获得了满意的美容效果。
