In patients undergoing hemodialysis (HD), the incidence of peripheral arterial disease (PAD) is high, leading to a severe condition; therefore, examinations that facilitate early diagnosis are necessary. The diagnostic accuracy of the ankle brachial pressure index (ABI) after walking, of which the cut-off value was corrected for HD patients, is higher than that of the ABI or toe brachial pressure index (TBI) at rest. Furthermore, the TBI after walking transiently induces marked perfusion disorder of the toes. The two procedures are useful for the early diagnosis of latent PAD in HD patients.
