title: Funnel technique for EVAR: "a way out" for abdominal aortic aneurysms with ectatic proximal necks.
abstract: BACKGROUND
  To describe an endovascular technique for proximal stent-graft fixation in patients with an abdominal aortic aneurysm and an ectatic aortic neck.
  
  
  METHODS
  We describe a method in which using currently available devices in a hybrid assembly offers another option for circumventing the limitations of problematic proximal fixation.
  
  
  CONCLUSIONS
  Through four examples, we illustrate the feasibility of placing a straight endograft as proximal extension of a bifurcated or aorto-uni-iliac graft in patients with a dilated proximal aortic neck. It appears secure and effective, with no type I endoleak or migration over a midterm follow-up.
