Schematic drawing of the oblique-cut method of constructing a sidewall aneurysm.
The aneurysm neck segment of venous pouch harvested from the EJV was cut approximately 45° angle to the aneurysm long axis (arrowhead). An elliptical arteriotomy, approximately 6 mm long, is created on the lateral end of the right CCA. The neck segment of the pouch is then sutured along the edges of the arteriotomy by using 6–0 Proline sutures, resulting in a berry-shaped sidewall aneurysm.
