摘要: Background A detailed knowledge of the morphology aorta and iliac arteries is an important prerequisite for successful endoluminal abdominal aortic aneurysm (AAA) repair. The best method preoperative evaluation remains to be determined. Methods A prospective study was undertaken between January 1994 July 1995 assess ability computed tomography (CT), magnetic resonance angiography (MRA), colour duplex imaging intra-arterial digital subtraction (IA-DSA) visualize AAA morphology. Results Eighty-two consecutive patients (64 men, 18 women) with were assessed MRA, contrast-enhanced CT, IA-DSA. Median age 74 (range 59–87) years median diameter 5·7 3·5–9·7) cm. Five unable tolerate CT or MRA examination. Seventy-seven underwent both MRA. Of these, 55 also had a scan 32 arteriography. scans by independent blinded observer. significantly better (P < 0·01) at visualizing compared imaging. There no statistically significant difference arteriography. Conclusion MRA useful in patient selection repair, as it avoids use iodinated contrast medium ionizing radiation. © 1998 British Journal Surgery Society Ltd
