INTRODUCTION: Staged endovascular treatment of @entity2334 ( @entity2334 ) has been proved to be an effective strategy to reduce the risk of @entity2759 ( @entity2759 ). Several techniques have been described: some imply the staged coverage of the aorta, other the temporarily perfusion of the sac through a branch left unstented or a dedicated branch that will be occluded later. The aim of those is to facilitate the expansion of the collateral network that perfuses the spinal cord. However, each of them, have some disadvantages such as the need of two interventions of big magnitude and the risk of target vessel occlusion or endograft displacement. We describe a new technique to treat @entity2334 in a staged manner. TECHNIQUE: The first step of our technique is the thoracoabdominal endograft deployment with the branching of all target vessels; one of these is branched with a bare stent inside which a covered stent will be placed in a second step, which can be perfomed under local anesthesia. We named this technique "open branch" ( @entity1538 ). Before insertion of the covered stent, a balloon is inflated inside the bare stent to simulate the complete sac exclusion to evaluate eventual @entity16 . RESULTS: Two @entity1 with Crawford type II @entity2334 and one with a suprarenal @entity439 following the open repair of an @entity449 were treated. No cases of @entity2759 were observed after the two procedures. Median interval time between the two procedures was 8, 6 weeks (4-16). Between the two steps, no @entity439 growth or @entity397 and no @entity732 or endograft displacement was observed. CONCLUSIONS: These three cases of " @entity1538 " technique show that this is a safe and feasible alternative strategy to treat @entity2334 in a staged manner.    2015 Wiley Periodicals, Inc.
