<p><b>BACKGROUND</b>Transfemoral
artery access is the main approach for the interventional
treatment of
renal artery stenosis (
RAS). This study aimed to investigate the technical feasibility of a transradial interventional (TRI)
treatment of
renal artery stenosis.</p><p><b>
METHODS</b>A series of 23
patients who underwent transradial
renal artery stenting from October 2010 to October 2011 were studied. Radial sheath system (Terumo,
Japan) was used to get access to the
radial artery. Radial
tourniquet (Terumo) was used to stop
bleeding. A 5Fr MPA (COOK, USA) was used to perform selective renal
arteriography. Percutaneous
renal artery stent systems were used to perform
renal artery stenting.</p><p><b>RESULTS</b>
Renal artery angiography showed that 15
patients had unilateral
renal artery stenosis and eight
patients had bilateral
renal artery stenosis. The
descending aorta could not be catheterized in one
patient because of the type III
aortic arch. Twenty-two
patients successfully underwent transradial
renal artery angiography and the technical success rate was 95.7%. There was no
puncture site
hematoma or
pseudoaneurysm. Mean
procedure time was (38.4 ± 7.2) minutes, the mean amount of
contrast agent used was (93.2 ± 6.3) ml, and the mean postprocedure
bleeding time was (3.2 ± 1.9) minutes.</p><p><b>CONCLUSION</b>Transradial
renal artery intervention is technically reliable with less invasion, rapid recovery, fewer
complications and may become an alternative intervention approach for the
treatment of
renal artery stenosis.</p>
