Purpose: To describe the planning and technique for implantation of the t-Branch off-the-shelf multibranched aortic endograft. Technique: Total endovascular repair of thoracoabdominal aneurysms (TAAAs) with branched endografts is one of the most important paradigm shifts in the past decade. The t-Branch endograft, an off-the-shelf multibranched graft introduced in the European market in late 2012, allows treatment of patients with suitable anatomy in both the elective and urgent settings to avoid delays related to manufacturing time of custom-made devices. The steps required for the planning and implantation of the device are described, including some tips and tricks. Conclusion: The use of an off-the-shelf multibranched device is an appealing option in the treatment of TAAAs, especially in the acute setting. Nevertheless, results of complex aortic repairs with this specific device are associated with a learning curve and can be improved by identifying a number of intraoperative risks and paying heed to several technical details.
