RESUMO
To describe a new inner-branched device used to treat two cases of chronic post-dissection aortic thoraco-abdominal aneurysms (PD-TAAAs) after ascending aortic surgery. A 67-year-old male who had undergone an ascending aorta and arch surgical replacement and a 70-year-old male with a previous Bentall procedure for acute type A aortic dissection were admitted at our department with a PD-TAAA diagnosis. Both patients were defined unfit for open surgery by a multidisciplinary team and a totally percutaneous endovascular repair was planned. A prophylactic cerebro-spinal fluid drainage was applied and at least one hypogastric artery was targeted for salvage in order to reduce the risk of spinal cord ischemia. A new inner branch device by Jotec® (GmbH/ Criolife; Hechingen, Germany/Kennesaw, Georgia) was implanted. A TEVAR and a standard EVAR completed the procedures and a double barrel technique was performed in order to achieve the preservation of the selected hypogastric artery. In both patients the complete technical success was achieved. The postoperative period was uneventful and the patients were discharged on the 6th and 7th postoperative day, respectively. The triple-phase angio-CT performed at 6 months showed the complete false lumen exclusion and the patency of the endografts and of the target visceral vessels. The total endovascular treatment of PD-TAAAs is a fascinating technique with encouraging results in experienced centers. Inner branched devices may expand the field of application of this new technology. More data are required to evaluate mid- and long-term results.
