A Demo Case with Prof. Luca Bertoglio
Case Context
This demo case shows how Prof. Luca Bertoglio, Associate Professor of Vascular Surgery at the University of Brescia, uses iSizing to plan a abdominal aortic aneurysm, from the initial CT through to a complete device configuration.
The patient presented with a 64.6 mm infrarenal AAA. The anatomy : A long proximal neck and a left common iliac that widened along its course. These are the features that most often complicate device selection and sealing, and they make a useful example of what automated sizing and interactive planning bring to the workflow.
Automated Sizing
iSizing began by segmenting the aorta automatically, accounting for both thrombus and calcification along the wall, calculating 100 diameters per cross-section to produce a reliable average and maximum at each point β around 80,000 measurements across the case. Within a few minutes, the neck, aneurysm, and both iliacs were fully characterised, with a long proximal neck confirmed in the 20.4β20.9 mm over its first 10 mm.
A full sizing report that would normally takes lot of manual measurement is ready in minutes, so the time from CT to a workable plan is dramatically shorter. For a busy service, that difference adds up across every case.
And since iSizing shows the interactive 3D model alongside the cross-sectional CT cuts at each level, Prof. Bertoglio could still check any measurement against the source images before relying on it.
Interactive Planning Agent
Once the anatomy was sized, Prof. Bertoglio moved straight into planning within the same tool. He selected a Medtronic Endurant IIs and saw it positioned on the patient-specific 3D model, with the endograft updating in real time as he adjusted the proximal and distal baselines.
When the configuration was settled, the complete sizing and planning report was generated in a single step. Interactive planning lets the surgeon preview the actual deployment of the stent-graft in the aorta rather than picturing it from axial slices.
Conclusion
iSizing gave Prof. Bertoglio a clear and consistent picture of the case before any device was chosen, and interactive planning let him fit that device to the patient and see the result directly. The combination turns planning from intense manual work into a few focused minutes, and lets the surgeon spend that time where it matters most.
