Skin perfusion pressure for predicting access-related hand ischemia following arteriovenous fistula surgery based on the brachial artery.

The SPP gradient and postoperative SPP values may be effective clinical predictors of ARHI occurring immediately and 6 months after surgery, respectively, with high specificity. These findings could allow clinicians to diagnose and begin early interventions to help prevent ischemic tissue damage in hemodialysis patients following AVF surgery.
