Fenestrated EVAR using physician-modified stent-grafts for thoraco-abdominal aortic lesions / 中华普通外科杂志

ABSTRACT

Objective To evaluate fenestrated endovascular aortic repair (FEVAR) using physician-modified stent-grafts (PMSGs) for thoraco-abdominal aortic lesions.Methods Seven cases of thoraco-abdominal aortic lesions (1 type Ⅲ thoraco-abdominal aortic aneurysm,1 type Ⅳ thoraco-abdominal aortic aneurysm,4 chronic thoraco-abdominal aortic dissection and 1 type Ⅰ endoleak after EVAR due to abdominal aortic aneurysm) were treated with FEVAR from Nov 2016 to Nov 2017.Results FEVAR was performed successfully in all cases.Type Ⅱ and Ⅲ endoleak occurred in 4 cases.One died of acute myocardial infarction 2 days postoperatively.Renal dysfunction deterioration occurred in one case of chronic dissection and improved after the medical treatment.Renal subcapsular hematoma was found in 2 cases postoperatively,and resolved after conservative therapy.Mean follow-up period was 7.2 months,target vessel patency was identified in 5 of the 6 cases.Conclusions FEVAR using PMSGs is a viable alternative to treat thoraco-abdominal aortic lesions.
