This randomized controlled trial evaluated a nurse-led combination of Xilang Loubao and standardized traditional Chinese medicine massage, guided by Doppler ultrasound, in outpatients with arteriovenous fistula (AVF) stenosis. Participants were assigned to the combined approach or mucopolysaccharide polysulfate cream plus routine care. At Day 90, mean stenotic-site diameter was 4.3 ± 0.7 mm in the intervention group versus 2.0 ± 0.4 mm in controls; brachial artery flow was 1086.6 ± 253.5 mL/min versus 482.9 ± 123.1 mL/min (all P < 0.001). The authors describe the approach as a potentially useful adjunct for AVF maintenance.
Key findings
- At Day 90, mean AVF stenotic-site diameter was 4.3 ± 0.7 mm with the combined approach versus 2.0 ± 0.4 mm with control care (P < 0.001).
- Brachial artery flow at Day 90 was 1086.6 ± 253.5 mL/min in the intervention group versus 482.9 ± 123.1 mL/min in controls (P < 0.001).
- Of 41 patients assigned to the intervention group, 40 completed the study; 35 of 41 controls completed it.
Why it matters
AVF stenosis can threaten the durability of dialysis access, while invasive procedures may involve trauma and recurrence. This trial reports improved ultrasound-measured vessel diameter and blood flow with a noninvasive, nurse-led adjunct approach over 90 days. These findings may inform further evaluation of supportive AVF care, but do not establish long-term patency or replace assessment of established interventions.
What to keep in mind
The study was conducted at one hospital, had withdrawals in both groups, and reports outcomes only through Day 90; the abstract does not provide longer-term patency results.
