When is safe to cover the left subclavian and celiac arteries. Part II: celiac artery.
Endovascular repair of thoracic and thoraco-abdominal aortic aneurysms became apparent as an alternative to open repair. When the distal landing zone proximal to celiac artery is inadequate, a traditional open surgical approach with thoracoabdominal aortic replacement concomitant with visceral and renal bypasses is necessary. Alternatively, either an abdominal hybrid procedure with debranching of the visceral vessels with subsequent thoracic stent graft placement or complete endovascular aneurysm exclusion with branched stent grafts is required. Extending the distal landing zone might be possible by covering the celiac artery origin. In this article, the authors review the anatomy of the celiac artery (SA) and the superior mesenteric artery (SMA) and consequences of CA coverage as scenery for a discussion of the ramifications of CA coverage during endovascular thoracic aortic repair (TEVAR). Summarizing the currently available literature, we will demonstrate the feasibility of covering the celiac artery based on a diagnostic algorithm.
