Misaligned deployment refers to eccentric flaring of the bare stent portion of the endograft that causes proximal device retroflexion resulting in suboptimal graft placement. A 71-year-old woman with 6.8-cm distal aortic arch aneurysm underwent hybrid repair with combination of open aortic arch debranching and subsequent thoracic endovascular aortic repair. During endograft deployment, misaligned opening occurred; this was corrected by using a balloon-assisted graft deployment. Follow up imaging continues to demonstrate complete aneurysm exclusion. Misaligned deployment is a clinical challenge; we hereby present a previously undescribed technique to accommodate this limitation of the current endograft technology.
