title: The use of a self-expandable aortic stent to incarcerate microcoils and to create a favourable infrarenal neck in an unusual case of endovascular abdominal aortic aneurysm repair.
abstract: BACKGROUND
  We report a case of an emergency high-risk patient with a pararenal aortic aneurysm.
  
  
  METHODS
  Our patient had a pararenal aneurysm with two components: a wide-neck saccular aneurysm below the left renal artery and a fusiform aneurysm. A self-expandable aortic stent was deployed covering both renal arteries, the saccular aneurysm was embolised with microcoils and a bifurcated aortic endograft was anchored inside the aortic stent. The aortic stent imprisoned the microcoils and avoided proximal type I endoleak. The tomography done 15 months after the procedure showed no endoleaks.
  
  
  CONCLUSIONS
  A self-expandable aortic stent can provide an alternative for emergency high-risk patients with pararenal aortic aneurysms.
