Hemodialysis access has been considered as a support for end-stage renal patients. We measured the hemodynamic changes of the distal part of the upper extremity immediately after providing the AVGs in each method mentioned above and then compared the results. This method is a novel one and hasn’t been used in any other studies before. We studied 32 patients referred to the vascular surgery department of Rasht Razi Hospital between 2019-2020 (using the Convenient Sampling method). This study is a case-control study. Out of 32 patients referred to the vascular surgery department of the hospital, 68.8% were male, and their mean age was 53.41±12.75 years, ranging from 28 to 78 years. Changes in distal arterial hemodynamics of the upper limb before and after clamping in dialysis venoarterial loop versus straight grafts are different in studied patients (P<0.05). The mean hemodynamic changes before and after clamping in loop venoarterial grafts (19.5000) are less than straight grafts. In dialysis patients who do not have any superficial vein suitable for venous, arterial fistula, surgical placement of artificial grafts in the upper limb is appropriate. Based on the results of this study, the loop method seems to have lesser ischemic Complications and can be applied to dialysis patients.
