Abstract
Type I endoleak is a well-known complication of endovascular repair which could be due to the patient or technical factors during the procedure. Every type I or type III endoleak should be repaired prior to completion of the endovascular repair procedure. In the case of type I endoleak aneurysm, the sac is still pressurized and will grow over time. Every attempt should be made to resolve endoleak prior to the completion of the procedure. Available strategies to treat type I endoleak include: (1) Repeat angioplasty of the seal zone; (2) Addition of an aortic cuff; (3) Use of balloon-expandable bare-metal stents to increase the radial force; (4) Use of endoanchors to obtain better graft/aorta apposition; (5) Extension of the graft with snorkel or fenestrated endograft to extend the seal zone beyond the visceral branches; and (6) Explantation and open repair.
