Fig. 19.1 Guidewire tip has been advanced into an MCA branch to enable ICA stenting. During manipulation, perforation of MCA occurred. In panel (a) the tip appears to be within the…

Fig. 1.1 A sterile angiography table is usually positioned behind the surgeon for easy access to equipment. The setup shown is prior to the patient being prepped and draped. The tubing…

Fig. 6.1 Fluoroscopy in AP view demonstrates a guidewire (long arrow) advanced through the femoral and iliac arteries toward the aorta. The sheath (delineated by the opposing small arrows) is already…
