Abstract

Background

Endovascular repair is fast becoming the treatment of choice for abdominal aortic aneurysms in anatomically suitable patients. 3D reconstructions not only aid conventional 2D measurements but also allow further analyses of the vessel anatomy.

Methods

Computed tomography scan data for four male patients awaiting endovascular repair were obtained. 3D reconstructions were performed to determine measurements. Wall stress was determined on one particular case using finite element analysis.

Results

3D reconstruction allows measurements to be obtained that can be difficult to determine using 2D images. This method complements traditional 2D approaches. Reconstructions also provided imaging of potential anatomical problems. Wall stress results showed key regions that may be possible rupture sites.

Conclusion

3D reconstructions greatly aid surgical planning. As stent-graft devices evolve, anatomical difficulties previously considered contraindications to endovascular repair can now be overcome with careful planning. 3D reconstruction is a useful adjunct to assessment and planning of endovascular repair.
