Exclusión endovascular de un aneurisma de la aorta abdominal con una endoprótesis fenestrada balón expandible

摘要

Endovascular repair of abdominal aortic aneurysms (AAA) is an attractive option to conventional surgery. The presence of one or both renal arteries emerging from the aneurysmal sac is the absolute limit for implanting a standard stent-graft. In these cases, the use of fenestrated devices that preserve blood flow to these arteries might constitute a therapeutic option to conventional treatment. The aim of this case report is to describe the implant of a balloon-expandable stent-graft using a fenestrated device in a patient with an AAA and only one kidney located in the pelvis with a renal artery emerging from the aneurysmal sac. A stiff guide-wire was introduced via the femoral artery and the aortic segment of the stent-graft was advanced. A second segment was introduced to connect the aortic trunk with the right common iliac artery. Finally, a third segment connected the fenestrated branch of the second segment with the renal artery. The procedure ended with the placement of an occluder device in the left common iliac artery and a femorofemoral bypass graft surgery. The clinical success achieved with this patient demonstrates that fenestrated stent-grafts are an option in complex anatomies and encourages us to keep on working with this type of devices.
