ObjectiveTo observe the effect of ultraintense laser irradiation on blood flow parameters of dorsalis pedis and arteriae tibialis posterior in the patients with diabetic foot. MethodsForty patients with diabetic foot were enrolled and were randomly divided into observation group and control group by drawing lots, with 20 cases in each group. The control group was administered the conventional vasodilator, the observation group received the ultraintense laser irradiation on the basis of conventional vasodilator. The parameters of dorsalis pedis and arteriae tibialis posterior were compared between the two groups before and after treatment, including peak systolic blood flow velocity (PSV), end-diastolic minimal blood flow velocity (EDV), blood flow volume, resistance index and stenosis degree. ResultsAfter treatment, the PSV, EDV, blood flow volume, resistance index and stenosis degree of dorsalis pedis and arteriae tibialis posterior were improved in the observation group compared to the control group(P＜0.05). ConclusionUltraintense laser irradiation can improve the blood flow parameters of dorsalis pedis and arteriae tibialis posterior, and the blood supply of the affected limbs in the patients with diabetic foot.
