Sonography of blood access in hemodialysis patients with 7.5MHZ transducer

Abstract

Chronic hemodialysis requires a wellfunctioning blood access. We examined 24 patients in our hemodialysis center by ultrasonography with 7.5MHZ transducer (LS-300).
The results were stenosis in 3 patients, abnormal dilatation of vein in 3 patients, the others were thrombosis, aneurysm, wall irregularity, extravascular hematoma. Non invasive ultrasonography is expected as the initial imaging procedure.
