Abstract

One of the technical limitations of surgeon-modified fenestrated stent grafts is the lack of a diameter-reducing wire, which facilitates catheterization of target branches if there are errors of device design, alignment, or implantation. This article describes a technique of adding a diameter-reducing wire to the modified TX2 fenestrated stent graft for compassionate use in aortic emergencies or high-risk patients who do not have access to manufactured devices. The modified Cook TX2 stent graft was created using reinforced fenestrations with gold nitinol markers. After the TX2 stent was fully unsheathed, one of the nitinol wires located in the inner cannula was withdrawn and redirected externally through and through the fabric of the stent graft. Each Z stent was constrained using the nitinol wire for support and two nonlocking polypropylene loops. The use of a diameter-reducing wire facilitates side branch catheterization by allowing longitudinal and rotational movement to the modified fenestrated stent graft in patients where there is misalignment between the fenestration and the origin of the target vessel.
