Percutaneous Transluminal

Purpose: To compare the safety and efficacy of X-ray-guided and ultrasound-guided percutaneous transluminal angioplasty in treating arteriovenous fistula dysfunction. Materials and methods: Data for 219 patients with arteriovenous fistula dysfunction between January 2016 and December 2018 were retrospectively analyzed. The primary endpoints were technical success, clinical success, and primary patency rates. The secondary endpoints were complications and secondary patency rates. Procedure outcomes and both endpoints were evaluated by propensity score analysis. Results: After the propensity score matching, 73 matched pairs of cases were created with 34 pairs of autogenous arteriovenous fistula cases and 39 pairs of prosthetic arteriovenous graft cases. There was no significant difference between the X-ray-guided and ultrasound-guided group, respectively, regarding the technical success rate (84.9% vs 87.7%, p = 0.630), clinical success rate (98.6% vs 97.3%, p = 0.999), and complications (10.9% vs 5.5%, p = 0.228). Although the 6- and 12-month secondary patency rates for the dialysis access between the two groups had significant difference ( p < 0.05), there was no significant difference in primary and secondary patency curves between the two groups ( p > 0.05). Conclusion: The overall efficacy of ultrasound-guided versus X-ray-guided percutaneous transluminal angioplasty in treating arteriovenous fistula dysfunction might be comparable.

Vascular Access Stenosis

Background: Stenosis is the main cause of arteriovenous fistula failure and is due to neointimal hyperplasia. Percutaneous transluminal angioplasty is the gold standard for patients with vascular access stenosis. The aim of the study was to evaluate the efficacy and safety of ultrasound-guided percutaneous transluminal angioplasty in the treatment of native arteriovenous fistula venous stenosis. Methods: The need for intervention was determined by physical examination and duplex ultrasound in 162 patients. All patients with failing or not maturing arteriovenous fistula were treated in the outpatient setting under ultrasound guidance. Procedural success was assessed with repeated post-procedural ultrasound examinations. All procedures were performed under local anesthesia by a single nephrologist and were performed in a single vascular laboratory, while follow-up ultrasound was performed in the dialysis unit of destination. Results: Early technical success was obtained in 95.6% of cases (154 of 162). Complications occurred in 22 patients (13.5%) with no major complication requiring surgical or fluoroscopic endovascular intervention. Primary patency at 6 and 12 months was 84% and 69.8%, respectively. Risk factors for arteriovenous fistula failure/secondary percutaneous transluminal angioplasty were vascular access low blood flow rate and vintage, as well as the need for thrombolysis during the first percutaneous transluminal angioplasty. Conclusion: Ultrasound-guided percutaneous transluminal angioplasty is a valuable tool to treat vascular access stenosis.
