Double micro-guide-wire technique to facilitate microcatheter navigation through tortuous intracranial vasculature.

We report a case in which navigation of the micro catheter (Headway 027) with the conventional single microwire technique became impossible because of the difficult intracranial vascular anatomy. In order to achieve access, we used two Terumo 012 inches micro guide-wires with a 45° angle inside a single micro catheter. The manoeuver was easy and can be reproduced in specific and challenging cases.
