BACKGROUND: Dysfunctional distal arteriovenous fistulas (AVFs) with small caliber distal inflow arteries theoretically require percutaneous transluminal angioplasty (PTA) throughout the entire arterial length. However, in clinical practice, whole distal inflow arterial PTA is not frequently performed due to concerns about possible arterial rupture. Therefore, we investigated the safety and efficacy of this procedure at our center, comparing it with the standard venous PTA. METHODS: From March 2017 to December 2022, 48 cases of distal AVF salvaged by whole distal inflow arterial PTA were assigned into a treatment group and 121 cases of distal AVF salvaged by venous standard PTA not involving the whole inflow artery were assigned into a control group. These two groups were then compared. RESULTS: Those in the treatment group (who received whole distal inflow arterial PTA) were older than those in the control group (mean age, 69 vs 59 years, CONCLUSION: Whole distal inflow arterial PTA is an effective and safe option for distal AVF salvage with a narrowed inflow artery, frequently refractory to conventional venous PTA.
