Endovascular aortic repair is feasible. In the Cleveland clinic experience in autoimmune aortitis of the ascending aorta, 37 patients had distal aorta Stent grafting. Success was 100%. In a mean follow up of ~ 4 years only one patient needed re intervention for endo leak.
My recommendation is EVAR. Better results will be obtained when the decision is at remission. However, if it has to be an emergency procedure, immunosuppression with high dose steroids is to be provided.
First one should be very sure if repair is needed at all. A biomechanical rupture risk assessment could help to clarify that, see our recent retrospective study about this concept in T.C. Gasser, A. Nchimi, J. Swedenborg, J. Roy, N. Sakalihasan, D. Böckler, A. Hyhlik-Dürr. A novel strategy to translate the biomechanical rupture risk of abdominal aortic aneurysms to their equivalent diameter risk: Method and retrospective validation. Eur. J. Vasc. Endovasc. Surg. 2014
in my experience i prefer Opel treatment, because it is the only possibility to achieve an specimen of aortic wall for histology. however you must consider the clinical condition of the patient. Only if there is a high riso of rupture you can do surgery o endosurgery out of the phase of remission of patology.
Relationship of Fluoroquinolone Use and Development of Aortic Aneurysms and Dissection
Although not in the context of Giant cell arteritis, one should avoid using fluoroquinolones in such patients due to risk of development of aortic aneurysms (1), and their dissection (2).
