Q. Explain Brachial or Radial Approach ?
This technique involves performing the coronary angiogram through the right brachial artery in the right ante-cubital fossa. Usually a 5F or 6F sheath is inserted and using a special catheter called the Sones catheter (designed by Dr. F. Mason Sones Jr.), the same process of cannulating the left and right coronary ostia under fluoroscopic guidance is performed. The same catheter is used for cannulating the left and right coronary ostia.
