Abstract:
[Objective]To discuss the changes and clinical significance of microcirculation in lower limbs in patients with lumbar canal stenosis under different circumstances.[Method]Prospectively,randomly,the nail fold microcirculation of the big toe in 50 patients were investigated with WX-6 microcirculation instrument before and after operation at 7~10 days and 3~6 months.The averages were compared with that of 30 healthy persons with q test.Two groups were defined according to the claudication distance as 0～100 meter and 300～400 meter and tested.The averages were analyzed with t test.[Result]There were statistically significant differences between the patients group and the healthy group and before and after surgery(P0.05).The most significant change was the form of blood flow.[Conclusion]The dysfunction of sympathetic nerve resulting from lumbar canal stenosis will impair the microcirculation of lower limbs and aggravate intermittent claudication.The operation will improve the microcirculation and alleviate the symptoms significantly.The microcirculation test in lower limbs can serve as an objective method for the preoperative diagnosis and postoperative assessment for therapeutic efficacy.
