Sizing for Endovascular Aneurysm Repair: Clinical Evaluation of a New Automated Three-Dimensional Software

Abstract

Sizing using the Endosize software is as reliable as conventional radiological procedures. Sizing by surgeons using an automated, user-friendly, and mobile tool appears to be reproducible.

Experimental validation of more realistic computer models for stent‐graft repair of abdominal aortic aneurysms, including pre‐load assessment

“…Moreover, all transverse shear stiffnesses (k 11 , k 22 and k 12 ) were defined as per Abaqus documentation. With these parameters, our models were already quite optimized in terms of numerical performance and accuracy, the latter being close to 5%, which represents errors within 2 mm for main body diameter and 10 mm for its length [20]. Indeed, for the sake of performance, beam and shell elements were used, as opposed to solid elements.…”

Evolution of the upper and lower landing site after endovascular aortic aneurysm repair

“…All preoperative and postoperative imaging was analyzed using the dedicated program, Endosize (Therenva, Rennes, France), which had previously been validated by our department (Fig 2). 7 All diameters were measured perpendicularly to the central line, from adventitia to adventitia, by the same person.…”

Combined Frozen Elephant Trunk and Endovascular Repair for Extensive Thoracic Aortic Aneurysms

“…The optimal sizing of the hybrid endoprosthesis represents a delicate issue [1]. We employed a dedicated automated three-dimensional software (Endosize, Therenva Inc., Rennes, France) as previously described [6]. Advanced imaging plays an incremental role in the management of aortic disease and may facilitate the application of less invasive approaches.…”

“…In the antegrade approach, thoracic stent-grafts were released from the opened aortic arch during hypothermic circulatory arrest. The preoperative planning of the procedure, the choice and sizing of prostheses were achieved using the Endosize sizing software (Therenva Inc., Rennes, France) on the basis of CT scan imaging [6]. Generally, endoprostheses were oversized by 10% to 15% with respect to the target distal aortic diameter; the same ratio was adopted for oversizing between contiguous thoracic endoprostheses.…”
