The necessary instruments needed to perform ICA infusions are commonly available in most labs including a light source, dissecting microscope, a hotplate, and a peristaltic pump (a). Following either inhaled or injected anesthesia, neck hyperextension is required for exposure of the carotid triangle (b). Schematic representation of each step of the ICA infusion in the carotid triangle containing CCA (black arrow), IJV (white arrowhead), and vagus nerve (black arrowhead) including catheter placement and eventual CCA ligation (c). Photomicrograph via a dissecting microscope (magnification, 6.5X to 35X) shows CCA (black arrow), IJV (white arrowhead) and vagus nerve (black arrowhead) (d). CCA was anchored with 5-0 black silk (white asterisk) (e). CCA was visualized as ICA (black arrow) and ECA (white arrow) diverged (f). A small arteriotomy (arrow) was made in the CCA with microscissors after applying 5-0 black silk (white asterisk) and a vascular clip (black asterisk) (g). A microcatheter (arrow) was cannulated through the arteriotomy (h) and secured with black silk ties (i). Two black silk ties (white asterisk) were permanently applied after removing the catheter (j).
