摘要: PURPOSE: To present a detailed description of aortic arch morphology in patients with aneurysm and dissection undergoing thoracic endovascular repair (TEVAR). METHODS: Morphological assessment the was performed consecutive series TEVAR between November 2003 April 2009. In absence standardized reporting criteria, any patient requiring overstenting left subclavian artery (LSA) considered to have pathology arch. all, 49 (31 men; mean age 70 years, range 43-86) analyzed (25 aneurysms 24 dissections). The proximal landing site intended stent-graft Ishimaru zone 0 2 (4%) patients, 1 11 (22%), 36 (74%). Measurements were made diameters angulation orientation supra-aortic trunks from 3-dimensional reconstructions computed tomography scans. RESULTS: diameter increased as it approached root (mean 38.9+/-6.4 mm at sinotubular junction versus 30.7+/-16.6 (LSA). Mean level LSA 117 degrees +/-23 . Five (10%) had common origin innominate carotid (LCCA). distance LCCA <15 80%; 37 (80%) clock-face positions ostia within 15 each other. There no statistical difference measurements patients. CONCLUSION: this cohort, similar for or dissection. majority cases shorter than recommendation an adequate zone. This data may assist development stent-grafts
