“…For evaluating dysfunctional access, the first and most cost-effective method is physical examination [ 10 – 13 ]. Ultrasonography confirms the physical examination results such as inflow stenosis, outflow stenosis, or simply deep-seated vein and provides important information about the functional severity such as brachial artery flow rates [ 14 – 17 ].…”

BackgroundThe use of ultrasound guided percutaneous transluminal angioplasty (UG-PTA), which use ultrasound as an imaging modality, is an evolving strategy. But, in Korea, this method is rarely used. We report our experiences with UG-PTA with respect to technical success rates and complication rates compared to conventional PTA (C-PTA), performed between 2010 and 2015 at Samsung Changwon Hospital, Korea.MethodsIn our series, 53 cases of UG-PTA and 90 cases of C-PTA were reviewed, respectively. Cases of central vein stenosis, cephalic arch stenosis, arterial stenosis and thrombosis were excluded. However, cases of juxta-anastomotic stenosis and outflow vein stenosis were included.ResultsTechnical success was achieved in 96.2% (51 of 53) of cases in the UG-PTA group and in 93.3% (84 of 90) of cases in the C-PTA group, respectively (P = 0.710). Technical failure was experienced in a total 8 cases (UG-PTA group: 2/53, 3.8%; C-PTA group: 6/90, 6.7%). No differences were observed in complications.ConclusionDuplex ultrasound-guided angioplasty for dialysis access in the outpatient setting is feasible, safe, and effective for peripheral venous stenotic lesions. It offers many advantages over conventional angiographic procedures, and, in the future, it has great potential to play a significant role in the management of these challenging patients.

“…In patients indicated for treatment owing to dialysis problems, physical findings and internal pressure changes (5-7), the vessel distribution and the stenosis were identified by ultrasound. Ultrasound-guided PTA was performed on those patients indicated for PTA treatment rather than surgical repair.…”

“…Duplex Doppler ultrasound, blood flow monitoring, and endovascular imaging can detect the stenosis or clot that was suspected on physical exam 4. Duplex ultrasound can reveal flow patterns, depth and sizes of vessels, stenotic lesions, and collateral veins 5.…”

“…Simple cues to stenosis or thrombosis in fistulas or grafts also include falling urea clearance (measured as urea reduction ratio or Kt/V), frequent clotting of dialysis tubing, suboptimal blood flow rates, and difficulty in cannulating the fistula 4…”
