Patients with occlusive disease of the subclavian artery or brachiocephalic trunk were examined by oscillography (17 cases) and digital pulse plethysmography (19 cases) before and after reconstruction of the occluded vessel. Before surgery the oscillographic amplitudes were significantly lower on the occluded than the contralateral arm, with no difference between the registration levels. Shape analysis of the digital pulse curve recordings gave significant differences in all variables, between the occluded and the contralateral arm, inclination time and RAMP25 being most sensitive. Idential studies repeated up to 6 months after surgery demonstrated a marked increase in oscillometric amplitudes at all levels on the operated side. In the digital pulse-curve recordings the greatest improvement was found in inclination time and RAMP25.
对锁骨下动脉或头臂干闭塞性疾病患者在闭塞血管重建术前和术后进行了示波检查（17例）和数字脉搏容积描记法检查（19例）。手术前，闭塞侧的示波幅度明显低于对侧手臂，记录水平之间无差异。数字脉搏曲线记录的形状分析显示，闭塞侧与对侧手臂在所有变量上均存在显著差异，倾斜时间和RAMP25最为敏感。术后长达6个月重复进行的相同研究表明，手术侧所有水平的示波幅度均显著增加。在数字脉搏曲线记录中，倾斜时间和RAMP25改善最为明显。
