Endovascular Management of Unused Fenestrations or Branches in Fenestrated/Branched Aortic Endograft

Fenestrated and branched aortic endograft (F/B EVAR) has become a widely accepted technique in the management of aneurysmal aortic pathology. However, intra-procedurally in some situations, there are F/B that remain unused because of target vessel occlusion or failure to cannulate the target artery. Leaving the F/B open will result in an ongoing endoleak, unless treated at the time. Herein we described the necessary considerations and several endovascular techniques to occlude these fenestrations and branches in this situation.
