Contrast-Enhanced MR Angiography of Failing Hemodialysis Arteriovenous Fistulas and Grafts: A Preliminary Experience
نویسندگان
چکیده
treatment of stenoses by percutaneous intervention has been shown to increase the longevity of the dialysis shunts (1, 2). In current clinical practice, detection and grading of the stenosis are usually performed using color doppler sonography and digital subtraction angiography (DSA) (3, 4). Color doppler sonography is obviously the first choice of diagnostic method and it can non-invasively demonstrate failing hemodialysis arteriovenous J Korean Radiol Soc 2004;51:609-614

Stenosis detection with MR angiography and digital subtraction angiography in dysfunctional hemodialysis access fistulas and grafts.
PURPOSE To prospectively assess three-dimensional contrast material-enhanced magnetic resonance (MR) angiography for stenosis depiction in malfunctioning hemodialysis arteriovenous fistulas (AVFs) and grafts (AVGs), as compared with digital subtraction angiography (DSA). MATERIALS AND METHODS Ethical review board approval and written informed consent were obtained. MR angiography and DSA were...
متن کاملThe experience use of drug-coated & non drug-coated balloons in arteriovenous fistula at a six months period: brief report
Background: The ineffectiveness of hemodialysis fistulas causes high costs and increases mortality and morbidity rates. The efficacy of drug-coated balloon and nondrug-coated balloon in dysfunctional arteriovenous Fistula was evaluated over six month period. Methods: In this randomized clinical trial, a total of a total of 50 hemodialysis patients who referred to Imam Reza Hospital in Kermansh...
متن کاملTime-resolved contrast-enhanced MR angiography of spinal vascular malformations.
BACKGROUND AND PURPOSE The diagnosis of spinal vascular malformations may be challenging on conventional MR imaging because neither the location of the signal abnormality in the spinal cord nor the level of the abnormal flow voids correlates with the level of the fistula. We conducted a retrospective evaluation of the utility of using a time-resolved imaging of contrast kinetics sequence in the...
متن کاملPreangiographic evaluation of spinal dural arteriovenous fistulas with elliptic centric contrast-enhanced MR Angiography and effect on radiation dose and volume of iodinated contrast material.
BACKGROUND AND PURPOSE The detection and localization of spinal dural arteriovenous fistulas (AVFs) remain diagnostic challenges. This study tested the hypothesis that elliptic centric contrast-enhanced MR angiography (MRA) can be used to detect spinal dural AVFs, predict the level of fistulas, and reduce the radiation dose and volume of iodinated contrast material associated with conventional ...
