Abstract

SOUSA, Pedro Filipe; FERREIRA, Joana; RAMOS, Rui  and  FRUCTUOSO, Monica. Focus on: II - Imaging in vascular access for haemodialysis. Port J Nephrol Hypert [online]. 2015, vol.29, n.4, pp.285-291. ISSN 0872-0169.

A reliable vascular access is essential to effective haemodialysis. Imaging evaluation of vascular access for haemodialysis includes preoperative assessment of vascular anatomy and post-operative surveillance for access maturation, as well as diagnosis in vascular access dysfunction. This article reviews the current diagnostic imaging methods in haemodialysis fistulas. Ultrasound is the technique of first choice when imaging vascular accesses. Digital subtraction angiography is superior for the assessment of the central veins and makes diagnosis and treatment possible in the same session

Keywords : Computed tomography; digital subtraction angiography; magnetic resonance; ultrasound; vascular access for haemodialysis.
