微循环检测诊断缺血性股骨头坏死的机理

缺血性股骨头坏死是常见的骨伤科疑难病症。目前国内外诊断缺血性股骨头坏死的常用方法是医学影像学检测。临床常用Ｘ线，ＣＴ，放射性核素成像，核磁共振（ＭＲＩ）和血管造影（ＤＳＡ）等，这些技术不仅为缺血性股骨头坏死提供诊断依据，同时也为判断疗效提供科学结论。但是，临床发现，仅靠上述影像学检测等诊断方法，尚不能及时准确发现缺血性股骨头坏死病变变化过程，而且检测结果反映的只是病变结果的局部病灶。当诊断确立后才开始治疗，时机已晚，病情难以逆转。１９９３年以来，我们运用微循环理论和技术，观察人体远端末梢的甲襞微…

Diagnosis for Ischemic Necrosis of Femoral Head by Microcirculation Detection

Observations on the pathological changes of microcirculation in nail folds were made through the theory and the detection of microcirculation to diagnose ischemic necrosis of femoral head at the early, mid or late stage. The detection was done for 15 746 cases of different diseases. Among them, 287 cases(1 82%)of ischemic necrosis of femoral head(136 at early stage and 151 at the mid or late stage) showed obvious changes in microcirculation. The changes included the morphologic maldistribution of blood vessel, blood exudation or stagnation, or increases of venous plexus, dynamic state of blood flow rate showing the aggregation of the red blood cell at varying levels and slow flow, stagnation or even slight embolism of the blood. After the herbal treatment to promote blood circulation to remove blood stasis and to dredge the channels, the microcirculation was obviously improved in varying degrees. Meanwhile, the X ray examination of ischemic necrosis of femoral head showed the significant improvement or disappearance on the focus of infection. This detecting method can be used to determined the non obvious symptoms of ischemic necrosis of femoral head at the early stage, the symptoms which can not be detected by the image examination.
