Treatment of Aneurysms
Posterior Communicating Aneurysm Shape the tip of the microwire to a ‘C’ shape by giving a bend to the wire at the tip and then another bend further proximally. Some…

Complications, Avoidance and Management
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…
Preparing for Angiography
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…
Navigation
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…
Access: Femoral, Radial, Brachial, Carotid
Fig. 2.1 Components of a micropuncture set. The 7 cm 21G needle (green hub) is still in a protective sheath that will be discarded when the needle is ready for use. The…
Intracranial Angioplasty and Stenting
Problem Solution Balloon catheter will not move forward despite advancing it This may be consequent to the guide catheter losing its position and dropping back into the ECA, CCA, or further…
