IRCT20200712048083N1 IRCT 2022-02-05 Tehran University of Medical Sciences Coronary angiography via left distal radial artery vs femoral artery Comparison of coronary angiography and percutaneous coronary intervention via left distal radial artery versus femoral artery in post coronary artery bypass grafting patients; A pilot study 2020-04-20 anticipated 60 Complete https://irct.ir/trial/49592 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Patients are divided into into two groups of radial and femoral access by 1:1 simple individual randomization method based on a table of random numbers created by a computer to carry out allocation concealment. Randomization was performed using "www.random.org" list generator. N/A Angiography/angioplasty of coronary arteries. Intervention 1: Intervention group 1: In this group, patients undergo angiography or angioplasty through the left distal radial artery and the two groups are compared in terms of contrast volume, fluoroscopic time, vascular complications after the procedure at the site of sheath implantation, total procedure time, amount of radiation received, amount of heparin, vascular spasm in radial method, number of wire and catheter used. Intervention 2: Intervention group 2: In this group, patients undergo angiography or angioplasty through the femoral artery and the two groups are compared in terms of contrast volume, fluoroscopic time, vascular complications after the procedure at the site of sheath implantation, total procedure time, amount of radiation received, amount of heparin, vascular spasm in radial method, number of wire and catheter used.
