Abstract

|
An endovascular repair of an abdominal aortic aneurysm (AAA) is technically less invasive than open surgery, but gives results as effective as open surgery if the anatomy is adequate. Unfortunately, 20-30% of AAA patients are not suitable for endovascular repair because they lack a sufficient proximal landing zone. In an effort to broaden the applicability of endovascular repair, the chimney technique has been introduced. This refers to deployment of a covered or bare-metal stent parallel to the main aortic endograft within the aneurysm, creating a conduit that runs outside the main aortic endograft into the aortic branches. We report the case of a 75-year-old male with a juxtarenal abdominal aortic aneurysm and multiple comorbidities who was treated successfully with an endovascular aneurysm repair using a chimney graft.
