Type Ⅱ endoleak is a frequently encountered complication following endovascular abdominal aortic aneurysm repair(EVAR),exerting significant impact on the prognosis of patients post-EVAR.The primary strategies for preventing type Ⅱ endoleak involve prestent implantation embolization of the branch artery within the aneurysm sac or post-stent implantation filling of the sac with Onyx or other specialized materials.Treatment modalities encompass con-servative management,embolization(via transarterial,translumbar,transcaval approaches),laparoscopic artery ligation,open surgery,among others.Transarterial and translumbar embolizations are commonly employed in clinical practice.Currently,there exists no consensus regarding the prevention and treatment of type Ⅱ endoleak.This article provides a review of recent research advancements in this domain to offer reference and assistance to clinicians in their clinical de-cision-making.
