摘　　要：目的开发、制作并使用下肢血管造影固定器,防止造影检查治疗过程中肢体的移动和旋转,保持解剖学体位。方法使用木片制成鞋底,鞋跟底部用强力胶固定一长条木块作为支撑条,使鞋底纵轴与支撑条呈85°,鞋底板两侧分别用强力胶粘合厚质面料向足背延伸出2个侧翼,两侧缝制尼龙搭扣;将116例患者随机分成两组,分别使用和不使用固定器行下肢血管造影,通过阅片,分析伪影和体位显示情况,用χ2检验进行统计学分析。结果不使用固定器组伪影显示率为62.07%,体位标准化率为60.34%,在控制体位的过程中容易疲劳;使用固定器组,伪影显示率为22.41%,体位标准化率为86.20%,使用较舒适。两组比较差异有统计学意义(P<0.05)。结论下肢血管造影固定器结构简单,使用方便,稳定性强,能有效防止下肢移动和旋转,值得推广使用。Objective To develop a lower limbs angiography fixture, which is used in preventing limb movement and rotation in the angiography examination and treatment process and maintaining the anatomical position. Methods Made wood chips into soles, fixed a long piece of wood as a support bar at the bottom of the glue, so that the angle of the longitudinal axis with the support bar was 85 degree, joint plus material with the sole plate on both sides with strong adhesive, with two protrudent flank, sewing velcro on both sides. 116 cases were divided into two groups, with and without lower limb angiography fixture, respectively. Analyzed the artifacts and body position vision. Statistics were performed using 2~ testing. Results Artifacts display rate of the group without using fixture was 62.07%, and the position standard rate was 60.34%. The patients got tired easily in the control position process. While the artifacts display rate of the group using fixture was 22.41%, and the position standard rate was 86.20%, with comfortable using experience. There were significant differences between the two groups （P〈0.05）. Conclusion The lower limbs angiography fixture is simple, easy to use, stable, and can effectively prevent lower limb movement and rotation, is worth of promotion.
