There is controversy as to whether angiographic needles without stylets produce more arterial damage than those with stylets. Iliac arteries from 15 fresh human cadavers were punctured 56 times with either an 18-gauge angiographic needle with a stylet or one without a stylet (28 punctures with each needle type). These puncture sites were serially sectioned and examined microscopically. Each needle tract was evaluated for margin irregularity, shape of puncture, and approximation of edges. No statistically significant differences in arterial wall changes were found. The authors' data suggest that the choice of beveled needle use in angiography can probably be made on a basis other than concern for differences in vessel wall damage secondary to the presence or absence of a stylet.
关于不带针芯的血管造影针是否比带针芯的血管造影针造成更多动脉损伤存在争议。使用18号带针芯的血管造影针或不带针芯的血管造影针对15具新鲜人类尸体的髂动脉进行了56次穿刺（每种针型各穿刺28次）。对这些穿刺部位进行连续切片并进行显微镜检查。对每个针道评估边缘不规则性、穿刺形状和边缘接近度。未发现动脉壁变化有统计学显著差异。作者的数据表明，血管造影中斜面针的选择可能基于除担心针芯存在与否导致血管壁损伤差异之外的其他因素。
