Materials and Methods: Ten identical, investigational, tubular, thoracic stent-grafts were deployed in a glass aortic flow model with a type I arch: 5 in zone 2 and 5 in zone 3. A pulsatile pump generated a flow of 5 L\/min with systolic and diastolic pressures (\u00b15%) of 105 and 70 mm Hg, respectively. The flow rates (\u00b15%) were 300 mL\/min in the subclavian arteries, 220 mL\/min in the vertebral arteries, and 400 mL\/min in the common carotid arteries (CCAs). The total amounts of air released in each supra-aortic branch and in the aorta were recorded. Results: The mean amounts of air measured were 0.82\u00b10.23 mL in the zone-2 group and 0.94\u00b10.28 mL in the zone-3 group (p=0.49). In the zone-2 group compared with zone 3, the amounts of released air were greater in the right subclavian artery (0.07\u00b10.02 vs 0.02\u00b10.02 mL, p&lt;0.01) and right CCA (0.30\u00b10.8 vs 0.18\u00b107 mL, p=0.04). There were no differences between the groups concerning the mean amounts of air measured in the right vertebral and all left-side supra-aortic branches. The amount of air released in the descending aorta was significantly higher in the zone-3 group vs the zone-2 group (0.48\u00b10.12 vs 0.13\u00b10.08 mL, p&lt;0.01). Small bubbles were observed continuously during deployment, whereas large bubbles appeared more commonly during deployment of the proximal stent-graft end and after proximal release of the stent-graft. Conclusion: Air is released into all supra-aortic branches and the descending aorta during deployment of tubular thoracic stent-grafts in zones 2 and 3 in an aortic flow model. Higher amounts of air were observed in right-side supra-aortic branches during deployment in zone 2, whereas significantly greater amounts of air were observed in the descending aorta during deployment in zone 3.<\/jats:p>","DOI":"10.1177\/1526602819849931","type":"journal-article","created":{"date-parts":[[2019,5,15]],"date-time":"2019-05-15T05:31:36Z","timestamp":1557898296000},"page":"448-455","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Distribution of Air Embolization During TEVAR Depends on Landing Zone: Insights From a Pulsatile Flow Model"],"prefix":"10.1177","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8826-3232","authenticated-orcid":false,"given":"Vladimir","family":"Makaloski","sequence":"first","affiliation":[{"name":"German Aortic Center, Department of Vascular Medicine, University Heart Center Hamburg-Eppendorf, Hamburg, Germany"},{"name":"Department of Cardiovascular Surgery, Inselspital, Bern University Hospital, University of Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0460-1589","authenticated-orcid":false,"given":"Fiona","family":"Rohlffs","sequence":"additional","affiliation":[{"name":"German Aortic Center, Department of Vascular Medicine, University Heart Center Hamburg-Eppendorf, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Constantin","family":"Trepte","sequence":"additional","affiliation":[{"name":"German Aortic Center, Department of Vascular Medicine, University Heart Center Hamburg-Eppendorf, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.
