Advancing loop technique for endovascular access to the anterior cerebral artery.

Abstract

Direct endovascular access to the anterior cerebral artery (ACA) with a guidewire and catheter is not always possible. A C-shaped guidewire advanced as a loop into the middle cerebral artery and then withdrawn to advance the guidewire into the ACA is a way to gain endovascular access to the ACA when the direct approach is unsuccessful.
