Laser Doppler imaging is a new, non-invasive technique allowing the spatial distribution and the temporal variation of the skin blood flow to be monitored. A mean blood flow value over an area, such as the finger-tip in the present study, can also be calculated. Recordings from 12 patients with a sutured ulnar artery following trauma did not significantly differ from those obtained in 14 controls. Four patients with a ligated ulnar artery, however, showed a slower restitution of blood flow values after cold provocation. All sutured ulnar arteries were found to be patent, which confirms that microvascular reconstruction of an injury to the ulnar artery at the wrist is worthwhile.
激光多普勒成像技术是一种新型无创技术，可用于监测皮肤血流的空间分布和时间变化。也可以计算某一区域（如本研究中的指尖）的平均血流值。12例外伤后尺动脉缝合患者的记录结果与14例对照组患者相比，无显著差异。然而，4例尺动脉结扎患者在冷刺激后血流值恢复较慢。所有缝合的尺动脉均通畅，这证实了腕部尺动脉损伤的微血管重建是值得的。
