Three-dimensional (3D) printing in vascular surgery is trending and is useful for the visualisation of intracranial aneurysms for both surgeons and trainees. The 3D models give the surgeon time to practice before hand and plan the surgery accordingly. The aim of this study was to examine the effect of preoperative planning with 3D printing models of aneurysms in terms of surgical time and patient outcomes.
Forty patients were prospectively enrolled in this study and divided into two groups : groups I and II. In group I, only the angiograms were studied before surgery. Solid 3D modelling was performed only for group II before the operation and was studied accordingly. All surgeries were performed by the same senior vascular neurosurgeon. Demographic data, surgical data, both preoperative and postoperative modified Rankin scale (mRS) scores, and Glasgow outcome scores (GOS) were evaluated.
The average time of surgery was shorter in group II, and the difference was statistically significant between the two groups (p<0.001). However, no major differences were found for the GOS, hospitalisation time, or mRS.
This study is the first prospective study of the utility of 3D aneurysm models. We show that 3D models are useful in surgery preparation. In the near future, these models will be used widely to educate trainees and pre-plan surgical options for senior surgeons.
血管外科中的三维（3D）打印呈发展趋势，对颅内动脉瘤的可视化对外科医生和实习生均很有用。3D模型让外科医生有时间提前练习并据此规划手术。本研究的目的是从手术时间和患者预后方面检验使用动脉瘤3D打印模型进行术前规划的效果。
40例患者前瞻性纳入本研究并分为两组：第一组和第二组。第一组仅在术前研究血管造影。第二组仅在术前进行实体3D建模并据此研究。所有手术均由同一位资深血管神经外科医生进行。评估人口统计学数据、手术数据、术前和术后改良Rankin量表（mRS）评分以及格拉斯哥预后评分（GOS）。
第二组的平均手术时间较短，两组之间差异有统计学意义（p<0.001）。然而，GOS、住院时间或mRS未发现重大差异。
本研究是对3D动脉瘤模型效用的首次前瞻性研究。我们表明3D模型在手术准备中有用。在不久的将来，这些模型将被广泛用于培训实习生并为资深外科医生预先规划手术方案。
