Progress in prevention and treatment of type Ⅱ endoleak after endovascular abdominal aortic aneurysm repair
Abdominal aortic aneurysm(AAA)is a life-threatening disease and its incidence is increasing year by year.Endovascular aneurysm repair(EVAR)is currently the most widely used treatment for infrarenal abdominal aortic aneu-rysms(AAA).Type Ⅱ endoleak is the most common complication after EVAR and the main reason for secondary postoperative intervention,however,the natural outcome and treatment of type Ⅱ endoleak are still controversial.This paper reviewed the literature on the research progress in the prevention and treatment of type Ⅱ endoleak to provide a reference for clinical decision-making.
