  • Title: Feasibility of angioplasty and stenting for abdominal aortic lesions adjacent to previously stented visceral artery lesions in patients with Takayasu arteritis.
    Author: Joseph G, George PV, Pati PK, Chandy ST.
    Journal: Cardiovasc Intervent Radiol; 2007; 30(2):293-6. PubMed ID: 17200901.
    Abstract:
    Two young female patients with Takayasu arteritis presented with symptomatic long-segment abdominal aortic stenosis in the vicinity of previously deployed celiac and renal artery stents that projected markedly into the narrowed aortic lumen. Crushing or distortion of the visceral artery stents during aortic angioplasty was avoided by performing simultaneous or alternating balloon dilatations in the aorta and in the visceral artery stents. Consequently, the visceral artery stents remained patent and shortened longitudinally, allowing unhindered deployment of Wallstents in the adjacent aorta and abolition of a pressure gradient across the aortic lesions. Access to side branches covered by the Wallstent was obtained without difficulty, enabling the performance of balloon dilatation in multiple side branches and ostial stent deployment in a renal artery. These techniques could increase the scope of endovascular therapy in the treatment of patients with Takayasu arteritis.
