We studied a series of 114 patients with ischemic peripheral vascular disease angiographically by conventional film-screen (CF) and by intra-arterial digital subtraction (DSA) techniques. The quality of films and images was evaluated at four anatomic levels. We reached the following conclusions: a) in most patients a DSA study will suffice for diagnosis; b) an ability to see arteries was related to the film or image quality; c) in the pelvis, although most studies were of excellent quality, more CF than DSA were of excellent quality; d) in the thigh, both CF and DSA studies were mostly of excellent quality; e) in the leg and foot, more DSA than CF studies were of excellent quality; f) patients preferred DSA to CF studies; g) physician acceptance of DSA was mixed; and h) good patient hydration can reduce the potential renal complications of the larger contrast loads used in CF studies.
我们通过传统的屏-片（CF）血管造影和动脉内数字减影（DSA）技术，对114例缺血性外周血管疾病患者进行了系列研究。在四个解剖层面评估了胶片和图像的质量。我们得出以下结论：a）在大多数患者中，DSA检查足以用于诊断；b）观察动脉的能力与胶片或图像质量有关；c）在骨盆部位，尽管大多数检查质量优良，但CF质量优良的比DSA更多；d）在大腿部位，CF和DSA检查大多质量优良；e）在小腿和足部，DSA质量优良的比CF更多；f）患者更喜欢DSA检查而非CF检查；g）医生对DSA的接受程度不一；h）良好的患者水化可以减少CF检查中使用较大造影剂负荷所带来的潜在肾脏并发症。
