摘要
Objective: The aim of the study was to evaluate the role of atherosclerosis risk factors and baseline inflammatory status in the development of restenosis after successful percutaneous transluminal angioplasty (PTA) of hemodialysis arteriovenous (AV) fistulas. Research design and methods: We obtained baseline plasma biochemistry and inflammatory markers in 140 patients with dysfunctional AV fistulas before the PTA procedures. Patients were followed clinically for 6 months. Results: There was no significant difference in the baseline inflammatory markers between the restenosis and patency group. The Kaplan-Meier analysis showed that non-diabetic patients had higher patency rate than diabetic patients (69% vs. 48%, p=0.02) and diabetic patients with optimal glycemic control had higher patency rate than patients with suboptimal glycemic control (61% vs. 30%, p=0.01). Conclusions: The presence of diabetes mellitus predicted restenosis of AV fistulas after PTA and optimal blood glucose control might be critical to the patency after PTA. © 2009 Elsevier Ireland Ltd.
