This study was undertaken to evaluate the patency rate of radial and ulnar artery repairs performed with use of the magnification afforded by the operative microscope. Color Doppler ultrasonographic imaging was chosen as a reproducible, noninvasive technique to evaluate patency and graphically display vascular flow characteristics. Twenty-eight consecutive patients with 35 arterial injuries form the study group. Twenty-four patients with 31 arterial lacerations were available for enrollment in the protocol. Follow-up ranged from 1 to 40 months (average, 10 months). Eighteen male and six female patients sustained 13 radial and 18 ulnar artery lacerations, all sharp. Four patients required interposition vein grafting. Overall patency after repair was found to be 84%, with 82% of single vessels and 86% of double vessels patent. The patency of single vessels repaired without the use of vein grafts was 100%. These results indicate that microscope-assisted repairs of the radial and ulnar arteries remain patent at a higher rate than is commonly cited.
本研究旨在评估在手术显微镜放大作用下进行的桡动脉和尺动脉修复的通畅率。彩色多普勒超声成像被选为一种可重复的、非侵入性技术，用于评估通畅情况并以图形方式显示血管血流特征。连续28例患者共35处动脉损伤构成研究组。24例有31处动脉裂伤的患者符合纳入该方案的条件。随访时间为1至40个月（平均10个月）。18例男性和6例女性患者发生了13处桡动脉和18处尺动脉裂伤，均为锐器伤。4例患者需要进行静脉移植。修复后的总体通畅率为84%，单支血管通畅率为82%，双支血管通畅率为86%。未使用静脉移植修复的单支血管通畅率为100%。这些结果表明，显微镜辅助下的桡动脉和尺动脉修复保持通畅的比例高于通常引用的数据。
