Abstract:
Objective To study the relationship between ultrasonography of arteria dorsalis pedis and Hemorheology in patient with diabetic foot.Methods According to with or without frank anabrosis,51 patients were devided into two sub-groups:anabrosis group (23 patients) and no-anabrosis group (28 patients).The correlativity was analysed between the parameters of ultrasonography in arteria dorsalis pedis and hemorheological indices on patients with diabetic foot.Results When compared to patients without ulcers,vascular inner diameter (D),peak systolic velocity (PSV),resistent index (RI) and pulsatility index (PI) on patients with frank anabrosis were decreased significantly,but whole blood viscosity at high shear rate (BVH),whole blood viscosity at low shear rate (BVL),plasma viscosity (PV),fibrinogen (Fib) were increased.Multiple regression analyses indicated that the relationship between BVH,BVL and D was presence,partial regression coefficient (r) was -0.004 and -0.009 ; the relationship between PSV and BVH,PV was intimate,r was -0.957 and -25.655 ; the relationship between RI and BVH,PI and BVH,PV,Fib were relatively intimate,r was -0.009 , -0.141 , -2.666 , -0.383 ,respectively.Conclusions The changes of hemorheology can aggravate the abnormality of hemodynamics and the degree of vascular lesion in small vessels of lower limb,so it is one of influencing factor leading to lower limb arterial ischaemia and diabetic foot deterioration.
