title: Transradial artery intervention: an alternative approach for renal artery stent implantation?
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
