Six-year clinical and computed tomography angiography follow-up after Nexus implantation

Endovascular aortic arch repair (Ar-TEVAR) with single-branch, off-the-shelf Nexus aortic arch system has shown promising early and 3-year outcomes. There is lack of data regarding long-term results of this specific device, particularly regarding patency of supra-aortic bypasses and stability of the connection between the 2 modules. This case report describes 6-year clinical and imaging follow-up of a 74-year-old patient who underwent Ar-TEVAR with Nexus. Over 6 years, the patient experienced minor complications unrelated to the device. The patency of supra-aortic bypasses and integrity of the device's connection were confirmed. Computed tomography angiography constantly showed exclusion of the aneurysm and reduction of the aneurysmal sac. In conclusion, although extended research and broader data are needed, this case provides encouraging evidence of long-term results of Ar-TEVAR with Nexus.
