摘要:

目的 探讨术前3D打印模拟技术在Stanford B型主动脉夹层介入腔内隔绝治疗中的指导作用。 方法 采用回顾性研究方案,选取本院2019年1月至2021年1月采取腔内隔绝手术治疗的Stanford B型主动脉夹层患者76例进行分析,其中40例患者术前采用3D打印技术模拟手术指导(模拟组),另外36例患者采取常规的腔内隔绝手术治疗(对照组),对比两组的术中术后指标、术前术后心脏超声指标、手术前后不同时间的主动脉近端破口平面、支架末端平面、腹腔干动脉平面的真、假腔内径及并发症率。 结果 模拟组患者的手术时间、体外循环时间、主动脉阻断时间、ICU停留时间均短于对照组,差异具有统计学意义(P < 0.05);两组患者在术后1、3、6个月的主动脉近端破口平面、支架末端平面、腹腔干动脉平面的真腔内径与本组术前比较均显著增大(P < 0.05),主动脉近端破口平面、支架末端平面、腹腔干动脉平面的假腔内径与本组术前比较均显著减小(P < 0.05);两组患者在术后6个月的LVEF、FS显著增大(P < 0.05)。 结论 术前3D打印模拟技术在Stanford B型主动脉夹层介入腔内隔绝治疗中应用在保证手术效果的同时,有利于降低手术操作难度,缩短手术时间,但在手术效果上与传统手术相比差异不大。

Abstract:

Objective To investigate the role of preoperative 3D printing simulation technology in the interventional endovascular exclusion of Stanford B aortic dissection. Methods A retrospective study protocol was used to select 76 patients with Stanford B-type aortic dissection who underwent endovascular isolation surgery in our hospital from January 2019 to January 2021 in the study. Among them, 40 patients underwent simulated surgery with preoperative 3D printing simulation technology (simulation group) and another 36 patients received conventional endovascular isolation surgery (control group). The two groups were compared in terms of the.cardiac ultrasound indicators, the true and false lumen diameters, and the complication rates of the proximal aortic rupture plane, stent end plane, and abdominal trunk artery plane at different times before and after surgery. Results As compared to the control group, the simulation group showed significantly longer surgical time, extracorporeal circulation time, aortic occlusion time, and ICU stay time (all P < 0.05). After the operation, the true lumen diameter of the proximal aortic rupture plane, stent end plane, and abdominal trunk artery plane were significantly increased in two groups at months 1, 3, and 6 (P < 0.05), but the false lumen diameter of the proximal aortic rupture plane, stent end plane, and abdominal trunk artery plane were significantly decreased (P < 0.05) compared to preoperative levels. The LVEF and FS of the two groups were significantly increased 6 months after surgery (P < 0.05). Conclusion The preoperative 3D printing simulation technology in the interventional endovascular isolation of Stanford B aortic dissection can ensure the surgical effect. It can achieve the same surgical effect as the traditional procedures and importantly it can reduce the difficulty of operation and shorten the operation time.
