Branched Endograft Partial Deployment to Save Space for Vessel Cannulation When Treating Aneurysms with Narrow Aortic Lumen

Purpose: To describe a novel technique developed for the treatment of patients with thoracoabdominal aortic aneurysms having narrow aortic lumens using branched endografts. Technique: When treating patients with a narrow aortic inner diameter with branched endografts, we propose a partial graft deployment leaving the distal portion of the device inside the delivery system with the aim of spare space and facilitate target vessel cannulation. Conclusions: Partial endograft deployment could be considered in the case of expected difficulty associated with encumbrance deriving from the distal straight graft portion. This technique could be useful to avoid target vessel loss and therein save procedural and fluoroscopy time.
