Safety and efficacy of renal arteriography and stenting via femoral versus radial access: A comparative study

Objective To evaluate the safety and efficacy of two different approaches of renal arteriography (femoral access vs radial access). Methods Patients with renal artery stenosis who underwent renal arteriography via femoral artery or radial artery in Chinese PLA General Hospital from January 2008 to April 2015 were included.X-ray exposure time, procedure time, dose of contrast agent, success rate of arteriography, comfort level, time in bed and complication rate were recorded, and the success rate of stenting and restenosis rate were compared in patients with renal artery stenting. Results Of the 1 286 cases with femoral arteriography, there were 663 males and 623 females with average age of (64.4±8.2) years (ranging from 41-82 years).Four hundred and sixty-three patients underwent renal arteriography via radial artery, including 275 males and 188 females with average age of (61.2±8.5) years (ranging from 40-80 years).No significant difference was found in sex and age between two groups (P> 0.05).X-ray exposure time (2.08±0.16) min vs (4.14±0.23) min and procedure time (5.37±1.78) min vs (9.06±2.58) min of femoral artery group were shorter than radial artery group (P< 0.05).The comfort level of radial artery group was higher than femoral artery group (57.2±11.3) vs (34.6±6.1), P< 0.05, while the time in bed of radial artery group was shorter than femoral artery group (1.5±0.42) h vs (23.2±1.65) h, P< 0.05.There were no significant differences in the dose of contrast agent (14.27±3.65) ml vs (15.09±3.48) ml, success rate (99.84% vs 99.35%) of angiography, complication rate (3.65% vs 4.10%), stenting success rate (6.93% vs 5.81%) and restenosis rate (6.93% vs 5.81%) between two groups (P> 0.05). Conclusion Patients with renal arteriography and stenting via radial access achieve better efficacy with less trauma, short time in bed and less adverse reaction.
