Abstract:
Objective To examine arteriovenous fistula (AVF) for hemodialysis by CT angiography(CTA).Methods Sixty-nine patients with chronic renal failure were enrolled in this study. CTA was undertaken by 256-slice scanner. A total of 100 ml of iohexol was administered at a rate of 3 ml/s into a vein of contralateral limb or external jugular vein.Imaging commenced after a delay of 25-30 s and 86 times imaging were performed. Results The AVF were clearly displayed on CTA. Eight CTA were normal. Twenty-five CTA showed stoma stenosis. Forty-two CTA showed venous stenosis. Ten CTA showed stoma stenosis combined with venous stenosis. Only one CTA showed artery stenosis. Conclusions CTA can reveal the AVF safely and correctly,which might help to find abnormality of AVF and direct treatment .
