Fixing Failing Fistulas
Researchers evaluated the immediate effect of UHP balloons and PCB in 22 patients (19 men) with failing fistulas in a randomized, control trial.
The researchers used the AngioFlow device to measure fistula blood flow. All patients had blood flow less than 500 mL/min. There were 12 patients in the UHP group and 10 patients in the PCB group. The patients had a mean age of 69 years (range: 42 to 88 years).
A total of 35 PTAs were performed, 15 in the PCB group and 20 in the UHP group. The technical success rate was 100%, with no major complications.
The UHP and PCB groups had a pre-intervention mean blood flow of 288 and 391 mL/min, respectively. After the procedure, it was 613 and 606 mL/min, respectively.
Post-intervention showed a mean increase in flow of 325.8 mL/min in the UHP group and 213 mL/min in the PCB group. Researchers reported findings here at the Society of Interventional Radiology annual meeting.
“This is the first study of its kind,” said lead investigator Sanjoy Kundu, MD, an interventional radiologist at
