title: Early experience with fenestrated stent grafts for treatment of juxtarenal aortic aneurysm.
abstract: BACKGROUND
  Fenestrated endovascular abdominal aneurysm repair (FEVAR) using branched arteries devices for visceral arteries is increasingly being used for the repair of juxtarenal aortic aneurysms (JAAs) in Europe, United States, Australia, New Zealand, and Asia. This study aimed to evaluate the technical feasibility and short-term results of FEVAR in treating JAAs in Japanese patients.
  
  
  RESULTS
  FEVAR with Cook fenestrated stent-graft (Cook Medical Inc., Bloomington, Indiana, USA) was performed for 5 patients at high risk for open repair of JAA. Seventeen visceral vessels were successfully accommodated with 12 fenestrations, and five visceral arteries with four scallops with a loss of renal artery. In one case, a type III endoleak occurred at a renal artery fenestration, and this had disappeared in the 1-month postoperative computed tomography (CT). The mean follow-up duration was 8 months. Iliac leg occlusion occurred in 1 case, which was treated with thrombectomy and additional leg device deployment. All patients had survived at the end of the follow-up period and continued their outpatient visits.
  
  
  CONCLUSIONS
  Implantation of a Cook fenestrated stent-graft incorporating the visceral arteries is technically feasible in high-risk Japanese patients with JAA and may be a viable alternative to current methods.
