Dialysis clears toxic waste
out of the patient's body and helps maintain the body 's fluid, electrolyte,
and acid-base balance. These
prosthetic fistulas work by connecting a patient 's vein with an artery in
their forearm, allowing high flow of blood from the artery to flow into the
vein. Haskal. 2002;39(2, Suppl.

graft keeps dialysis access open for at least six months longer than balloon
angioplasty, allowing dialysis patients to continue life -preserving treatment

combining diagnostic imaging expertise with advanced procedural skills,
interventional radiologists perform minimally invasive treatments that have
less risk, less pain, and less recovery time than open surgery. Centers for Medicare + Medicaid Services (CMS).

An extremity MRI is great for claustrophobic, pediatric and elderly
patients because scan times are faster than whole body scans, averaging less

"This study, the first large study

the current treatment by prolonging the function of a patient's bypass

By clinical patency measures, at six months 81
percent of stent graft patients had functioning accesses -- a highly
statistically better percent than the gold standard balloon angioplasty group. Interventional

Since only the extremity enters the machine, this allows for a

Patients with chronic renal failure need regular hemodialysis because
their kidneys are no longer functioning properly. When failure occurs, per National
Kidney Foundation Guidelines, an interventional radiologist normally performs
a balloon angioplasty to reopen the fistula and regain access for dialysis.6 deaths per

LAS VEGAS, Desert Radiologists , Nevada's largest
and most trusted medical imaging company, today announced the addition of a
new high-field extremity MRI used for imaging of the hand, wrist, elbow, foot,
ankle or knee. Because the equipment is designed specifically for
orthopedic applications, no attachments or heavy coils /devices are placed on
the patient. Failing or occluded dialysis access grafts
causes considerable morbidity, discomfort, and inconvenience for dialysis
patients due to the need for invasive procedures to reestablish access flow,
or to graft abandonment and reoperation.
