Carotid-compression technique II. A, The coaxial system (Shuttle, Cook/Glidecath, Terumo, Bloomington, Ind) is inserted into the ascending aorta, and the guidewire and inner catheter are then introduced into the target CCA or ICA by using the turn-over technique. B, The CCA is then compressed manually (arrow) to stabilize the guidewire and inner catheter. C, Withdrawal of the system toward the femoral artery results in its straightening. D, The guiding catheter is then advanced along the inner catheter. Arrowheads indicate the tip of the guiding catheter.
