Abstract

The functional microcirculatory system of the meniscus was investigated in nine sheep using laser Doppler flowmetry (LDF). The highest blood flows recorded were found at the periphery and at the anterior and posterior horns, and this finding was confirmed by india ink injections in five sheep and by meniscal autoradiographs following intraatrial injection of 20 million Cs46 microspheres in four sheep. LDF provides accurate and reproducible assessment of meniscal blood flow. If adequate probes can be developed, this method offers great promise in the clinical assessment of blood flow within the substance of meniscal tears, thus offering the surgeon initial information in the decision to repair or resect a meniscal tear.

摘要

使用激光多普勒血流仪（LDF）对9只绵羊的半月板功能微循环系统进行了研究。记录到的最高血流出现在半月板周边以及前后角，在5只绵羊中通过墨汁注射以及在4只绵羊中通过心房内注射2000万个Cs46微球后的半月板放射自显影片证实了这一发现。LDF可对半月板血流进行准确且可重复的评估。如果能够开发出合适的探头，这种方法在临床评估半月板撕裂部位的血流方面具有很大前景，从而为外科医生在决定修复或切除半月板撕裂时提供初步信息。
