Abstract
BACKGROUND: Arterio-venous (a-v) fistulae of haemodialysis patients frequently require function assessment by angiography. The purpose of the present study was to determine the efficacy and safety of ultrasound-guided transbrachial catheterization when a-v fistulae were evaluated. METHODS: Between July 1996 and December 1997, 208 dialysis patients, whose a-v fistulae (arterial inflow < 50 ml/min or venous pressure > 150 mm Hg in three consecutive HD sessions) were at the wrist or elbow, underwent transbrachial angiography using an ultrasound-guided 20-gauge IA needle to evaluate fistula function. Procedure-related symptoms or complications were noted in 28 patients and these were analysed. RESULTS: No apparent cases of vessel spasm or thrombosis were noted. Reported symptoms in 28 patients (13.5%) included local arm pain (3.3%), transient paresthesia (0.9%), mild ecchymosis (10.6%) and haematoma (0.9%). All complications were minor and none required surgical intervention. CONCLUSION: Ultrasound-guided puncture of the brachial artery is a safe, reliable and effective procedure in skilled hands and should be the preferred means of catheterization whenever haemodialysis angiography is performed.
