75 patients with difficult occlusions in the superficial and popliteal arteries were treated by the "Rotacs" system. This technique is efficient in treating occlusions longer than 10 cm, with an initial success rate of 60.5%. In primary failed conventional angioplasties Rotacs-PTA was successfully employed in 56% as a second intervention. This is considered to be an advance in PTA technique. In stage II disease the PTA results are better than in diseases of the stages III and IV, which agrees with conventional catheter treatment. In the femoropopliteal overlapping segment the initial successful PTA of short, hard, mostly calcified occlusions was only 33%. The complication rate of Rotacs technique compares with that of the conventional methods.
75例浅表动脉和腘动脉存在复杂闭塞的患者接受了“Rotacs”系统治疗。该技术在治疗长度超过10厘米的闭塞方面效果显著，初始成功率为60.5%。在初次常规血管成形术失败的病例中，Rotacs - PTA作为二次干预措施，成功率达56%。这被认为是血管成形术技术的一项进步。在II期疾病中，血管成形术的效果优于III期和IV期疾病，这与传统导管治疗的情况一致。在股腘重叠节段，短而硬、大多钙化的闭塞病变初次血管成形术的成功仅为33%。Rotacs技术的并发症发生率与传统方法相当。
