Endovascular Repair of a Juxtarenal Abdominal Aortic Aneurysm Using a Chimney Graft / 대한내과학회지

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.
