钬激光原位开窗技术在主动脉病变腔内治疗中的应用
Holmium laser in situ fenestration in thoracic endovascular repair of aortic lesions
目的 探讨钬激光原位开窗技术在主动脉腔内隔绝术中保留弓上分支动脉的作用及疗效.方法 对2016年11月至2017年2月收治的12例病变紧邻弓部分支血管、腔内修复治疗近端锚定区不足的主动脉病变患者的临床资料进行回顾分析.在数字减影血管造影下对胸主动脉及左颈总动脉和(或)左锁骨下动脉开口行腔内隔绝后,应用钬激光对覆膜支架进行原位开窗,重建左颈总动脉和(或)左锁骨下动脉的血流.结果 手术成功率100%,无Ⅰ型或Ⅱ型内漏发生,1例术后发生左视网膜分支动脉栓塞.术后随访6~9个月,中位随访时间7.3个月.主动脉内支架位置良好,左颈动脉及左锁骨下动脉开窗支架通畅,无移植物相关的漏血发生,无其他严重术后并发症发生.结论 激光原位开窗技术可以为病变邻近主动脉弓部重要分支动脉的患者提供腔内隔绝术治疗机会,避免开放手术重建主动脉弓部血管带来的创伤,短期随访结果满意.
更多Objective To evaluate the efficacy and safety of holmium laser in situ fenestration for aortic arch diseases during thoracic endovascular repair.Methods The clinical data of 12 patients with aortic dissection or aortic pseudoaneurysm was analyzed from Nov 2016 to Feb 2017.After thoracic aorta stenting the left common carotid artery and left subclavian artery were reconstructed using holmium laser in situ fenestration.Results The success rate of operation was 100%,no type Ⅰ or type Ⅱ endoleak occurred,1 case complicated with left retinal artery occlusion.All patients were followed up for 6 to 9 months,the mean time was 7.3 months.The location of the stent graft was good.The left carotid artery and left subclavian artery kept patent.Conclusions The laser in situ fenestration technique can provide the opportunity of stenting for patients with aortic arch lesion near the branch.Short term follow-up results were satisfactory.
