探讨透视虚拟技术在神经介入治疗微导管塑型中的应用及效果。

选取大连大学附属中山医院神经外科自2015年7月至2017年7月收治的60例未破裂窄颈后交通动脉瘤患者，采取随机抽签方式分为新技术组和常规组，每组30例。2组均在术前常规行头颈部CTA检查，根据检查结果，新技术组应用透视虚拟现实技术重建4D影像呈现载瘤动脉及动脉瘤开口方向，辅助微导管塑型；常规组实施常规介入治疗方式。比较2组手术时间及并发症的发生率。

成功栓塞2组共60例后交通动脉瘤，新技术组出现并发症患者1例，常规组出现并发症患者5例。新技术组平均手术时间[（39.700±2.583）min]少于常规组[（55.800±1.671）min]，差异具有统计学意义(P<0.05)。

应用透视虚拟技术塑形微导管，不但缩短了常规手术时间，而且可在术前评估动脉瘤开口、角度以及载瘤动脉是否狭窄等信息，增加了手术可控性及安全性。

To explore the effect and the application of perspective virtual reality technology in neural interventional therapy for micro-catheter molding.

Sixty patients with posterior communicating unruptured artery aneurysms who were treated with endovascular treatment were admitted to our hospital from July 2015 to July 2017. All cases were randomly divided into new technology group (30 cases) and traditional group (30 cases). All the aneurysms were found by routine CTA examination before operation. According to the imaging results of head and neck CTA, the 4D images were reconstructed by virtual reality technology, and the direction of the aneurysm and the parent’s artery was showed directly. New technology group use VR to guide the micro-catheter fit the aneurysms. Traditional group is traditional interventional therapy. Comparison of the length of operation time and the incidence of complications in the two groups.

Sixty posterior communicating artery aneurysms were successfully embolized. New rechnology group was to be with perspective virtual reality technology, and only one postoperative complications occurred. Five postoperative complications occurred in traditional group, The operation time in new technology group is (39.700±2.583) min, and the time in traditional group is (55.800±1.671) min, the difference between the two is significant (P<0.05).

Using perspective virtual technology to shape the micro-catheter not only shortens the time of conventional intervention surgery, but also improves the controllability and safety of the operation by using virtual technology to evaluate the aneurysm neck opening, angle and the stenosis of the parent artery before the intervention surgery.
