The therapeutical procedure in acute and chronic arterial obstructions of the pelvic and upper leg arteries may often be based on the results of intravenous DSA (i.v. DSA). In patients with peripheral arterial disease and before interventions below the knee are contemplated, i.v. DSA is not sufficient and has to be replaced by arterial DSA (IA DSA). I.v. DSA facilitates technical planning and performance of radiological vascular interventions and has the potential to reduce the complication rates. Nevertheless, the definitive decision to perform PTA and the choice of the appropriate technique continue to be made on the results of the arteriography/i.a. DSA, which has to be routinely obtained at the beginning of any procedure.
盆腔和大腿上部动脉急性和慢性阻塞的治疗程序通常可基于静脉数字减影血管造影（i.v. DSA）的结果。对于患有外周动脉疾病且考虑在膝下进行干预之前的患者，i.v. DSA并不充分，必须由动脉数字减影血管造影（IA DSA）替代。i.v. DSA有助于放射学血管介入的技术规划和实施，并有可能降低并发症发生率。然而，进行经皮腔内血管成形术（PTA）的最终决定以及合适技术的选择仍然取决于动脉造影/i.a. DSA的结果，而动脉造影/i.a. DSA必须在任何程序开始时常规获取。
