A journal article was submitted detailing a retrospective single-center study to evaluate efficacy of percutaneous transluminal angioplasty (pta) for the endovascular management of arteriovenous fistula (avf) dysfunction in patients with end-stage renal disease (esrd).
135 patients were included in the study who underwent endovascular treatment for a dysfunctional native avf.
Medtronic¿s standard pta balloons (4-9mm) were used during the procedure to treat avf dysfunction.
The balloon was maintained inflated for 2 minutes, and the procedure was repeated if necessary.
Pta was technically successful in 100.
0% of operations, with residual stenosis (>30%) in 5.
2% of patients.
Pta revealed clinical success in terms of adequate dialysis after the procedure in 97.
0% of patients, with complications only in 7.
4%.
Complications reported include vasospasm (7 patients), ad hematoma (2 patients).
Rupture is reported in 1 patient.
During the follow-up period of 6 months the avf remained patent in 94 patients (median primary patency duration of 5.
0 months).
Dysfunction recurrence reported in 41 patients, restenosis (7 patients) and occlusion (34 patients).
