[IL-3] Chimney procedures in thoracic and abdominal endovascular aortic repair
The chimney procedure is an endovascular solution to preserve aortic branch vessels and to lengthen the proximal or distal landing zone during thoracic or abdominal endovascular aortic repair (TEVAR and EVAR). Immediate type Ia endoleak is not uncommon.
Between January 2010 and August 2014, we have performed 592 endovascular aortic repairs (thoracic aorta: 223, abdominal aorta: 364, suprarenal or thoracoabdominal aorta: 5). Among them, 15 and 19 patients had chimney grafts for arch and visceral branches, respectively. Chimney grafts were deployed in a total of 48 branch vessels: 2 innominate, 9 left common carotid, 7 left subclavian, 1 aberrant right subclavian, 1 celiac, 9 superior mesenteric and 20 renal arteries.
In this presentation, we will review patient demographics, operative details, peri-operative results and mid-term outcomes, with a particular focus on the fate of immediate type Ia endoleaks.
