"Radial artery access is a minimally invasive approach for vascular access in interventional procedures. This route has widely been adopted since it reduced significantly the transfemoral-related complications. It is the recommended access route by the European Society of Cardiology for angiography and interventions in patients with ST-elevation myocardial infarctions1."
"Compared to transfemoral or transbrachial access, the radial approach decreases the incidence of complications such as2,3:"
"Radial access is a harder technique compared to the femoral approach and is associated with a higher cannulation failure rate4 because:"
"the "radial cocktail" should be diluted with approximately 20 ml of aspirated blood and injected over one minute, to avoid patient discomfort during the injection6"
"lidocaine 1% mixed with Isosorbide dinitrate - to promote arterial dilatation."
"the needle tip should be headed towards the navigation direction (towards brachial artery), and should be at 45º from the skin surface."
"any resistance is abnormal and require visualisation under ultrasound/fluoroscopy."
"the transducer is placed 2.5 - 5 mm from the needle tip"
"The causes of guidewire resistance may be :"
"radial artery occlusion - higher risk when the ratio of radial artery inner diameter to sheath catheter outer diameter < 1 7"
