Frameless stereotaxy-assisted clipping of distal anterior cerebral artery aneurysm: Technical note and case series

Figures & data

Figure 1. A digital subtraction angiogram of the left common carotid artery demonstrates an aneurysm at the bifurcation of the left A2 artery. (a) Lateral view. (b) Oblique view.

Figure 2. Preoperative targeting of the distal left ACA aneurysm using a CT angiographic data set loaded into the surgical navigation system. The aneurysm is seen at the center of the crosshairs in the coronal, sagittal, and axial orthogonal planes. [Color version available online.]
