Correct answer is (d) arm or groin
The explanation: The arm or groin, both provide large access areas for catheterisation. The aorta is accessed easily and the so the inserted catheter has an open path for the journey. First, an insertion is made and then a thin plastic tube is inserted to keep the incision open. Then a guide wire is sent in. Once the guide wire is in place, the catheter is sent which follows the path that is laid by the guide wire.
