Multi-slice CT angiography versus duplex ultrasound in detection of stenosis of access arteriovenous fistulas and grafts in dysfunctional hemodialysis
Purpose: To assess the accuracy of MS-CTA for the detection and grading of stenosis in AVF and AVG in comparison with colored Duplex. Patients and methods: Prospective analysis of vascular access related data was obtained from 30 patients (10 Males, 20 Females and age range 18–62 years) referred fro...
