Endovascular repair of an abdominal aortic aneurysm associated with crossed fused renal ectopia

Abstract

Chimney/snorkel endovascular aneurysm repair (Ch-EVAR) enables the minimally invasive treatment of abdominal aortic aneurysm in anatomically challenging and high-risk surgical cases. Here, we present the case of a 77-year-old man with an abdominal aortic aneurysm associated with crossed fused renal ectopia and an ectopic renal artery arising directly from the aneurysm sac. After successful implementation of Ch-EVAR, computed tomography angiography at 18 months revealed no endoleaks, patency of the parallel graft, and normal renal vascularization and function. This report underscores the feasibility of Ch-EVAR in a case with high anatomic complexity. (J Vasc Surg Cases and Innovative Techniques 2020;6:140-2.)

Renal ectopia as cause of diagnostic difficulties in 43-year-old man hospitalized due to suspicion of colorectal cancer

“…In the literature, there are case reports showing the technical aspects of the endovascular treatment of abdominal aortic aneurysm in patients with renal ectopia [14,15,16]. Tsuboi et al [17] reported a case of partial nephrectomy in patients with left-to-right crossed fused renal ectopia with clear cell renal cell carcinoma.…”

Endovascular aortic aneurysm repair with reversed chimney graft technique in a patient with crossed fused renal ectopia: a technical note

“…[ 9 ] and Colacchio et al . [ 10 ] placed self-expanding endografts (Viabahn Endoprosthesis, LG GORE, Delaware, USA) into RAs that arose from the AAA sacs in their cases. Here, we opted for the reversed chimney graft technique using Viabahn VBX, a balloon-expanding endograft.…”
