Abstract
A 125 cm long catheter makes it possible to perform renal arteriography via radial artery, but its feasibility and safety remain unclear. Our study recruited 1,323 patients grouped by two different vascular accesses to renal arteriography, i.e., femoral artery access and radial artery access. The success rate of angiography was 100% in both groups. Differential analysis showed that the overall complication incidence of radial artery access group was significantly lower (2.5% for radial artery access vs. 4.8% for femoral artery access, p = 0.03). From this study, we suggest that using the 125 cm angiographic catheter to perform renal arteriography via radial artery access is feasible and safe.
Highlights
Atherosclerosis is the main cause of renal artery stenosis
From 1,323 patients enrolled in our study, renal arteriography was performed in 612 patients via radial artery access (RAA) and 711 patients via femoral artery access (FAA)
There presented no significant difference between the two groups in baseline characteristics (Table 1)
Summary
Atherosclerosis is the main cause of renal artery stenosis. The incidence of atherosclerotic renal artery stenosis (ARAS) rises with the progress of population aging [1, 2]. There exists a high rate of diagnostic omission errors for ARAS because asymptomatic patients usually cannot receive timely treatment until renal function deteriorates and cardiovascular injuries occur [3]. The femoral artery is the traditional access of renal arteriography and is preferred by most hospitals and interventional doctors. The femoral artery access (FAA) can cause strong discomfort, high incidence of complications such as hematoma and bleeding, and has been almost completely replaced by radial artery access (RAA) in the coronary intervention [6].
