The possibility of employing peripheral venous and peripheral arterial digital subtraction angiography was examined in 351 patients of 65 to 95 years of age with arterial occlusive disease of the lower extremity. After peripheral venous contrast medium injection (using a Venflon needle 1.7-2.0 mm, 40 ml nonionic contrast medium, 20-30 ml NaCl, flow 15/s), conclusive assessment of vascular tone is possible in 86% of the cases. Indication for IV DSA is supplied chiefly by stenoses and occlusions situated proximally or bilaterally in the region of the distal aorta abdominalis, the iliacal, femoral and popliteal arteries. The distal adjacent segment is demonstrated well in 81 to 95 per cent of the cases up to the level of the trifurcation. Image quality is poor in 30% of the images of the lower leg, whereas no assessment is possible in 11% of the cases. IA DSA with fine needle (needle 0.8 mm, 3-5 ml contrast medium, 3-7 ml NaCl) is indicated in 8% of the patients to clarify the distal lower leg arteries, especially in preceding extensive proximal vascular occlusions. Conventional angiography can be largely replaced by combining peripheral venous and peripheral arterial DSA with fine needle technique.
对351例65至95岁患有下肢动脉闭塞性疾病的患者进行了外周静脉和外周动脉数字减影血管造影的可行性研究。在外周静脉注射造影剂后（使用1.7 - 2.0毫米的Venflon针，40毫升非离子型造影剂，20 - 30毫升氯化钠，流速15/秒），86%的病例能够对血管张力进行确定性评估。静脉数字减影血管造影（IV DSA）的适应症主要由腹主动脉远端、髂动脉、股动脉和腘动脉近端或双侧的狭窄和闭塞提供。在81%至95%的病例中，直至分叉水平，相邻远端节段显示良好。小腿图像的30%图像质量较差，而11%的病例无法进行评估。8%的患者需要用细针进行动脉数字减影血管造影（IA DSA）（0.8毫米针，3 - 5毫升造影剂，3 - 7毫升氯化钠）以明确小腿远端动脉，特别是在先前存在广泛近端血管闭塞的情况下。外周静脉和外周动脉DSA与细针技术相结合可在很大程度上替代传统血管造影。
