Bail-out technique to detach a locked Viabahn Endoprosthesis in branched TEVAR
2021
Abstract A 69-year-old female patient presented with a 5.8cm thoraco-abdominal aortic aneurysm Crawford type II after partial arch replacement. She was treated by a branched thoracic endovascular aortic repair (B-TEVAR) procedure using a branched arch endograft with one retrograde branch to the left subclavian artery. After deployment of a Viabahn as bridging covered stent to the left subclavian artery the deployment line did not detach and the delivery catheter could not be removed. With use of a physician modified sidehole catheter and balloon fixation the pulling line could be released without displacement of the Viabahn endoprosthesis.
