The ultrasound protocol, performed with Motion-Mode module and according to standard technique [13], provided, through the temporal acoustic window, the analysis of the following arterial vessels: internal carotid artery (ICA) in its distal portion, middle cerebral artery (MCA), section A1 of the anterior cerebral artery (A1-ACA), and posterior cerebral artery (PCA), in order to assess the possible MFV rate variations in response to the administration of IFN-[beta].

For example, for basilar apex aneurysms, the distal end of the first stent is positioned into the posterior cerebral artery (PCA) that arises at the most acute angle from the basilar apex (or the one with the most difficult configuration to navigate), with the proximal end positioned in the distal basilar artery itself.
