Twenty-eight patients referred for peripheral vascular imaging were investigated by both venous digital subtraction angiography and conventional aortography. A comparison of the two techniques revealed that, in the femoral region, venous digital subtraction angiography demonstrated all the abnormalities shown by aortography but missed three major and eight minor stenoses in the iliac region, due largely to bowel artefacts.
28名因外周血管成像前来就诊的患者接受了静脉数字减影血管造影和传统主动脉造影检查。两种技术的比较显示，在股部区域，静脉数字减影血管造影显示出了主动脉造影所显示的所有异常情况，但由于肠道伪影，在髂部区域遗漏了3处主要狭窄和8处次要狭窄。
