Abstract
Thoracic endografting has been proposed as an effective alternative to open repair to treat several aortic pathologies. Cranial migration is one of the critical issues concerning long-term durability. The scalloped thoracic endograft was proposed to improve distal sealing and fixation crossing the diaphragm. The objective of this study was to evaluate technical feasibility and experience with a custom-made scalloped thoracic endograft using the Relay platform (Bolton Medical, Sunrise, FL) in selected cases. From January 2006 to June 2009, 57 patients (40 men) were treated in Europe with a customized distal scalloped thoracic endograft. Forty-five patients presented with thoracic aortic aneurysm, nine presented with type B dissection, and three had a pseudoaneurysm. Successful and accurate deployment was achieved in all cases except one partial rotation in an extremely tortuous anatomy. Technical success was achieved in 96.4%. Good sealing and no mortality, paraplegia, or visceral embolization were observed. At a mean follow-up of 6 months, no complications were registered. The Relay endograft with the distal scallop represents a feasible alternative for distal short necks. This approach may increase the applicability and durability of the endograft in short distal necks.
