Abstract:
Objective To assess the feasibility and effectiveness of percutaneous transluminal angioplasty (PTA)for the salvage of immature arteriovenous fistula (AVF) and to identify the incidence of arterial and venous puncture site spasm.Methods The medical records and radiological data of 88 patients with 112 interventional procedures for immature AVFs were retrospectively reviewed.Results The stenosis lesions were (2.0 ± 1.4) cm long.Technical success rate and clinical success rate were 80.4％ (78/97) and 92.8％ (90/97) for PTA via brachial artery,85.7％ (6/7) and 100％ (7/7) for PTA via vein,25％ (2/8) and 50％ (4/8) for PTA via both brachial artery and vein,respectively.Spasm of pure arterial PTA occurred in 2 patients (2.1％) and was mild and moderate.Spasm of pure venous PTA occurred in 2 patients (28.6％) and was both moderate.Spasm of combined arterial and venous PTA occurred in 3 patients (37.5％) and from being severe to completely occluded.By comparison,there were statistical differences of technical and clinical success rate (P =0.000,0.019 ; P =0.000,0.029),fistulas spasm rate was statistically significant different (P =0.000).Conclusions Endovascular therapy was effective in restoring the dysfunctional native AVFs,it was safer and more effective and with less sideeffects especially in selecting coronary balloon to treat patients without large phlebangioma and round fistulas.
