Morphological study of abdominal aortic aneurysm: optimal stent-graft size for Japanese patients.

Abstract

PURPOSE:

We report on the optimal stent-graft (SG) size for Japanese patients with abdominal aortic aneurysm (AAA).

MATERIALS AND METHODS:

Ninety three Japanese patients undergoing elective AAA repair were selected for this study. The parameters measured were the proximal neck (PN) diameter (D1), the diameter of the right and left common iliac arteries (D2 and D3, respectively), the diameter of the right and left external iliac arteries (D4 and D5, respectively), the distance between the lowest renal artery and the common iliac arterial bifurcation (L1), and the distance between the right and left common iliac arterial bifurcations and the internal iliac arterial bifurcation (L2 and L3, respectively).

RESULTS:

The following results were obtained: D1: 20.7+/-3.9 mm (14 to 28 mm); D2: 14.0+/-3.0 mm (9.5 to 20 mm); D3: 13.8+/-3.1 mm (9 to 19.5 mm); D4: 7.5+/-1.0 mm (6 to 10 mm); D5: 7.4+/-0.9 mm (6 to 10 mm); L1: 107.7+/-13.4 mm (80 to 130 mm); L2: 40.0+/-10.1 mm (20 to 61 mm); L3: 39.7+/-9.6 mm (20 to 60 mm).

CONCLUSION:

The results indicate the necessity of exercising adequate care when selecting a device for Japanese patients.
