Abstract:
Objective To evaluate the effects of different dialysis treatment on femoral artery elasticity in uremia patients by Echo-tracking technique. Methods 81 cases of uremia patients (42 peritoneal dialysis patients and 39 hemodialysis patients) and 31 cases of normal adults as control were recruited in this study. The Intima-media thickness (IMT), Internal systolic diameter (Ds), Internal diastolic diameter (Dd), Value difference between Dd and Ds (△D), Arterial stiffness (β), Pressure strain elastic modulus (Ep), Arterial compliance (AC), Pulse wave conducting velocity (PWVβ) and Augmentation index(AI) parameters were analyzed for evaluation the right femoral arterial elasticity. Results The parameters ofβ, Ep, PWVβin dialysis patients significantly increased (P<0.05) and their AC significantly decreased (P<0.05) compared with normal group. Theβand Ep in hemodialysis patients is higher that those patients not receiving dialysis (P<0.05). Theβand Ep in peritoneal dialysis patients is lower that those patients not receiving dialysis (P<0.05). Theβ, Ep and PWVβin hemodialysis patients are higher than those in peritoneal patients (P<0.05). And AC is lower than control group (P<0.05). In uremia patients, Vascular stiffness was positively correlated with age, duration of dialysis, IMT, pulse pressure, Dd, and negatively correlated with△D(P<0.05). Conclusions Femoral artery endothelial function in uremia patients was damaged earlier than morphological changes. Vascular intimal injury resulting from hemodialysis is more serious, and vascular elasticity decrease is correlated with age, dialysis duration and pulse pressure. Echo-tracking technique could provide quantification evidences for early diagnosis of the femoral artery endothelial dysfunction in uremia patients. The echo-tracking technique has certain significance in early intervention and improvement the prognosis, however, the influence factor of the accuracy of measurement should be consider during the procedure.
