Interactive Application to Visualise the Use of the Fenestrated Anaconda AAA Stent Graft for the Treatment of Juxtarenal Abdominal Aortic Aneurysms

Abdominal Aortic Aneurysm (AAA) is a condition that affects the lower portion of the aorta; the major artery carrying blood from the thoracic region down to the rest of the body (British Heart Foundation, 2020). If the aneurysm ruptures it requires immediate surgery to repair the aorta (British Heart Foundation, 2020). Custom-made devices for fenestrated endovascular aneurysm repair (FEVAR), are now utilized on these patients that are at high risk for open repair surgery. Specialized stent grafts allow clinicians to accommodate specific vessels to insert custom devices where disease progression has occurred, higher up in the aorta (Davies, 2016). These fenestrations align with the branch vessels to enable the insertion of the branch stent thus providing perfusion to the renals, superior mesenteric artery (SMA) and coeliac artery. The Fenestrated Anaconda™ AAA Stent Graft (Terumo Aortic) provides all of these aforementioned features.

Rationale

It is difficult to visually communicate the customizable features of the Fenestrated Anaconda AAA Stent Graft to clinicians and exactly how this device provides better methods for treating FEVAR cases. An application containing a series of descriptive three-dimensional models and animations was created to increase clinicians’ understanding of specialised features and for public engagement at medical conferences in the future.

Objectives

1. To design and develop anatomically accurate and photorealistic 3D models and animations corresponding to the surgical intervention for abdominal aortic aneurysms.

2. To implement interactive paradigms through mobile visualisation that lets clinical specialists visualise how the stent graft is inserted into the abdominal aorta.

3. To assess the anatomical accuracy of the models, the usability and informative value of the interactive development involving a reduced sample of participants from the current cohort of clinical specialists at Terumo Aortic.
