Abstract

Endovascular aneurysm repair is a minimally invasive, durable and effective alternative to open surgery for treatment of abdominal aortic aneurysms (AAA). However, in patients who do not have an adequate sealing zone, open surgical repair is required, which may increase mortality and morbidity. An alternative treatment in patients with challenging anatomy is the so-called "chimney graft" technique. Here, we describe a case using the chimney graft technique for treatment of juxtarenal type I endoleak followed by a previous conventional stent graft insertion to the AAA with good results.

Figure

• 

  Fig. 1 Initial aortogram showed an infrarenal abdominal aortic aneurysms with severe neck angulation.

• 

  Fig. 2 Following angiogram showed a significant amount of type I endoleak (arrow) on the right side of the proximal attachment site of main body.

• 

  Fig. 3 Angiogram showed a large amount of type I endoleak.

• 

  Fig. 4 Viabahn stent graft was inserted in the left renal artery parallel to the aortic stent graft.

• 

  Fig. 5 The amount of type I endoleak showed a marked decrease.
