Abstract:
Objective To determine the long-term outcomes of renal interventional therapy in patients with renal artery stenosis. Methods One hundred thirty-four consecutive patients reveived renal stenting in our hospital. The changes of BP and serum creatitine were measured 24 hours after the procedure and during the first and second year of follow-up. Results All procedures were performed successfully. The mean serum creatitine level increased [(109.8?24.6) ?mol/L vs (99.4?27.8 baseline level) ?mol/L] and the glomerular filtration rate decreased [(57.6?19.3)mL/min vs (68.5?18.9) mL/min] significantly after the procedure. However during the first and second year of follow-up, the serum creatitine level returned to the pre-procedure level. Sixty-four patients attained benefit of BP improvement at about 6 months after renal artery stenting. The mean systolic pressure 6 months after the procedure was (148.6?22.6) mm?Hg (1 mm?Hg=0.133 kPa), which was significantly lower than the baseline level. During the first and second year of follow-up, there were 56 patients (50.6%) and 50 patients (49.6%) achieved BP improvement from renal stenting respectively. Conclusion Renal stenting is efficient and has satisfactory long-term outcomes in treating renal artery stenosis.
