“…). This compares favorably with other reported smaller series ranging in size from 10 to 73 cases with a technical success rate from 59% to 100%. These reports documented a primary patency of 36% to 77%, 18% to 60%, and 18% to 70% at 3, 6, and 12 months, respectively.…”

The purpose of this study was to report the results obtained in a cohort of 520 cases of thrombosed arteriovenous fistulas (AVF) treated by percutaneous intervention over a period of 8 years. The methods used varied according to the individual characteristics of the case. A clinical success rate of 91.1% was obtained with no significant difference being noted among radial-cephalic, brachial-cephalic, and brachial-basilic AVFs. The mean primary patency for this group was 227.3 ± 14.6 days, and the mean assisted primary patency was 677.2 ± 44.6 days. The lower arm AVFs had both a primary patency and an assisted primary patency that were significantly better than the upper arm cases (p = 0.006 and 0.002, respectively). The primary patency for radial-cephalic AVFs was significantly better than that for brachial-cephalic AVFs (p = 0.021), but not for brachial-basilic cases (p = 0.122). Assisted primary patency for radial-cephalic cases was significantly superior to the values for either patients with a brachial cephalic (p = 0.046) or a brachial-basilic (p = 0.004). Complications occurred in seven cases (1.3%), all of which were venous ruptures. Blood flow was affected in four cases. Only one of these was salvaged with angioplasty balloon tamponade. In the remaining three cases, the AVF was lost.

“…This implicates that optimal timing for PTA on the treatable lesions is crucial and early referral for PTA is a good policy as described in a couple of articles . Apart from the results of stenotic lesions, long lesions were associated with the poorer patency outcome as consistently shown in a few studies , despite insignificant differences in systolic RAPs observed between long and short lesions in the study. Furthermore, the distal RAP may become normalized or optimized when a successful PTA is achieved.…”

“…A radiocephalic AVF (RCAVF) constructed with an anastomosis of the radial artery and cephalic vein commonly results in juxta-anastomotic venous stenosis. Percutaneous transluminal angioplasty (PTA) is considered the first-line modality to manage the stenosis-related dysfunction (3,4,(9)(10)(11)(12)(13)(14)(15)(16). For RCAVF venous lesions, angiography-guided transradial PTA has been reported to be safe and effective (12,13).…”

Distal radial artery pressure (RAP) was observed to be reduced after transradial percutaneous transluminal angioplasty (PTA) on the juxta-anastomotic venous stenosis of radiocephalic arteriovenous fistula (RCAVF). Distal RAPs are easily obtained from a pressure transducer connected with an introducer retrograde inserted into distal radial artery. The clinical role of distal RAP in the setting of transradial PTA remains unknown. This prospective and observational study aimed to explore the relationship between distal RAPs and clinical outcomes. This study recruited hemodialysis patients with RCAVF juxta-anastomotic venous stenosis undergoing transradial PTA. RAP-related variables and procedural data before PTA (pre-PTA) and after PTA (post-PTA) were analyzed. The study endpoint was dysfunction-driven re-PTA during the 1-year follow-up. Overall, 73 PTAs significantly reduced the mean of systolic RAPs from 159.6 ± 41.4 to 108.4 ± 41.5 mm Hg; P < 0.0001. Post-PTA systolic RAP was associated with angiographic outcome (P = 0.004) and unassisted patency at 3 months (P = 0.036), but not at 6, 9, or 12 months (P > 0.05). The group with angiographically successful PTAs had a significantly lower mean of post-PTA systolic RAPs compared with that with unsuccessful PTAs (98.4 ± 35.4 vs. 128.7 ± 46.1 mm Hg; P = 0.003). The post-PTA systolic RAP may be seen as a predictor for 3-month unassisted patency (AUC = 0.669; P = 0.048). In conclusion, this study provides the RAP profile to help guide transradial PTA on RCAVF juxta-anastomotic venous stenosis and predict 3-month unassisted patency in a hemodynamic manner.
