Holmium laser in situ fenestration in thoracic endovascular repair of aortic lesions / 中华普通外科杂志

ABSTRACT

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.
