Hand acceleration time (HAT) as a diagnostic tool in the assessment of haemodialysis access-induced distal ischaemia (HAIDI): study protocol for a prospective cohort study in the Barcelona south metropolitan area.

ABSTRACT:

Introduction

Chronic hand ischaemia may affect some haemodialysis patients with an arteriovenous fistula (AVF) or graft (AVG), a condition known as haemodialysis access-induced distal ischaemia (HAIDI). Duplex ultrasonography (DUS) can provide comprehensive insights into anatomical and perfusion properties, and measuring the hand acceleration time (HAT) has been demonstrated to be sensitive within the framework of chronic upper limb ischaemia.

Methods and analysis

This single-centre, prospective cohort study will involve adult end-stage renal disease (ESRD) patients requiring either AVF or AVG for haemodialysis. The primary outcome will be HAT values (measured at the radial, ulnar and four hand arteries) before and after surgery. Secondary outcomes will include the incidence
