Abstract

Objectives: To determine the full range of aorto-iliac anatomy of patients with abdominal aortic aneurysms (AAAs) and thence the range of endovascular graft sizes required to deal with the majority of AAAs. Design: Analysis of preoperative spiral CT measurements Materials: One hundred and sixty-eight patients with AAAs Method: Multiplanar reconstruction measurements were taken of proximal aortic neck diameter and length, lowermost renal artery to the aortic bifurcation distance and length and diameter of common iliac arteries. Based on these measurements a range of graft sizes that would fit the majority of AAAs was determined. Results: Ranges of anatomical variables were as follows: proximal aortic neck diameter 18-30 mm, renal artery to aortic bifurcation distance 93-210 mm, common iliac artery length 13-108 mm, common iliac artery diameter 6-67 mm. Over 750 graft sizes would be required to cover all anatomical combinations using a one-piece aorto-uni-iliac graft. Conclusion: A wide variety of aorto-iliac anatomy exists in patientswith AAAs. The large number of graft sizes required to deal with the majority of AAAs makes the production of one-piece endovascular graftscommercially impractical. A proposed two-piece modular graft would allow the majority of AAAs to be treated using only 16 graft sizes.
