16 fresh postmortem specimens of human femoral and popliteal arteries with severe atherosclerosis were removed and angiography was performed. Eight vessels were completely occluded and eight showed stenoses of up to 60%. All occluded vessels were heavily calcified. The duration of occlusion, estimated according to the patient's history, ranged from 1 to 2 years. In one case, a duration of 18 months was documented by angiography. The lengths of the occlusions were between 5 and 12 cm. A rotating catheter was introduced through a 9F guiding catheter. All stenosed vessels were passed and seven out of eight occluded vessels, in which passage was not possible using conventional wires, were successfully reopened at low speed rotation of 200 rpm. Angiography, as well as histology, showed no perforation, and angioscopy revealed a smooth surface of the new channel. In three vessels this new channel was dilated with a balloon catheter and in one with an elastic element under rotation. It is concluded that with the new technique it is possible to reopen totally occluded human arteries which cannot be passed by conventional methods.
取出16个患有严重动脉粥样硬化的新鲜人体股动脉和腘动脉尸体标本，并进行血管造影。8条血管完全闭塞，8条血管显示出高达60%的狭窄。所有闭塞血管均有严重钙化。根据患者病史估计，闭塞持续时间为1至2年。在1例中，血管造影记录的闭塞持续时间为18个月。闭塞长度在5至12厘米之间。通过9F引导导管插入旋转导管。所有狭窄血管均被通过，8条闭塞血管中有7条使用传统导丝无法通过，在200转/分钟的低速旋转下成功重新开通。血管造影以及组织学检查均未显示穿孔，血管内镜检查显示新通道表面光滑。在3条血管中，使用球囊导管扩张了这个新通道，在1条血管中，在旋转状态下使用弹性元件进行了扩张。得出的结论是，采用新技术有可能重新开通传统方法无法通过的完全闭塞的人体动脉。
