Aim of the study was to evaluate the technical aspects of colour coded duplex sonography guided interventions of peripheral vessels.
During 15 months 39 stenoses of shunt veins in 24 patients were dilated guided by colour coded duplex sonography.
38 stenoses were dilated without complications. The blood flow volume was increased from 361.9 +/- 83.5 to 718.9 +/- 189.2 ml/min. In one case it was not possible to dilate the stenosis because of a vasospasm.
PTA guided by colour coded duplex sonography is an alternative to DSA guided interventions of superficial vessels without x-ray exposure or contrast agent application.
本研究旨在评估彩色编码双功超声引导下外周血管介入治疗的技术要点。
在15个月期间，在彩色编码双功超声引导下对24例患者的39处分流静脉狭窄进行了扩张。
38处狭窄扩张成功且无并发症。血流量从361.9±83.5毫升/分钟增加到718.9±189.2毫升/分钟。有1例因血管痉挛未能扩张狭窄部位。
彩色编码双功超声引导下的经皮腔内血管成形术是数字减影血管造影引导下浅表血管介入治疗的一种替代方法，无需进行X线照射或使用造影剂。
