摘要

目的

研究3D打印辅助预开窗胸主动脉腔内修复术（TEVAR）治疗累及左锁骨下动脉的Stanford B型主动脉夹层（TBAD）的效果。

方法

选取2020年1月至2024年12月遂宁市中心医院收治的190例累及左锁骨下动脉的TBAD患者，按随机数字表法分为原位开窗组（95例）、3D预开窗组（95例）。原位开窗组患者行原位开窗TEVAR治疗，3D预开窗组患者行3D打印辅助预开窗TEVAR治疗。对比2组患者手术相关指标、手术效果、内漏发生情况及其他并发症发生情况。

结果

3D预开窗组患者透视时间、辐射总剂量面积乘积均短/少于原位开窗组（

0.05）；2组患者手术时间、锚钉区域长度、主动脉支架成功释放且左锁骨下动脉重建成功率、手术成功率、内漏发生率、二次手术率及其他并发症发生率比较，差异均无统计学意义（

0.05）。

结论

3D打印辅助预开窗与原位开窗TEVAR治疗累及左锁骨下动脉的TBAD均具有良好手术效果，且3D打印辅助预开窗技术可缩短术中透视时间，减少术中辐射剂量。

Abstract

Objective

To investigate the efficacy of 3D printing-assisted pre-fenestration thoracic endovascular aortic repair （TEVAR） in the treatment of Stanford type B aortic dissection （TBAD） involving the left subclavian artery.

Methods

A total of 190 patients with TBAD involving left subclavian artery in Suining Central Hospital from January 2020 to December 2024 were selected and divided into in situ fenestration group （95 cases） and 3D pre-fenestration group （95 cases） according to the random number table method. Patients in the in situ fenestration group were treated with in situ fenestration TEVAR， and patients in the 3D pre-fenestration group were treated with 3D printing-assisted pre-fenestration TEVAR.The operation related indexes， operation effect， occurrence of endoleak and other complications were compared between the two groups.

Results

The fluoroscopy time and total radiation dose area product of patients in the 3D pre-fenestration group were less

than those in the in situ fenestration group （

0.05）. There were no significant differences in operation time， length of anchor area， successful release of aortic stent and success rate of left subclavian artery reconstruction， success rate of operation， occurrence of endoleak， rate of secondary operation， and incidence of other complications between the two groups （

0.05）.

Conclusion

Both 3D printing-assisted pre-fenestration and in-situ fenestration TEVAR treatments for TBAD involving the left subclavian artery demonstrate good surgical outcomes，and the 3D printing-assisted pre-fenestration technique can reduce intraoperative fluoroscopy time and radiation dose.
