Augmented Reality in the Surgery of Cerebral Aneurysms

Neurosurgery

Augmented reality aided clipping of an unruptured, 4 mm, growing left posterior communicating artery aneurysm in a patient with a past medical history significant for the clipping of a ruptured left MCA aneurysm five years earlier and for the placement of a Pipeline stent due to neck re-growth. Before incision (00’06’’-00’34’’): The patient is settled in the supine position and her head is turned to the right. Skull exposition (00’35’’-01’05’’): The superior orbital rim, zygoma and titanium plate from a previous intervention are seen. The segmented skull images are superposed. After craniotomy (01’06’’-02’08’’): Arachnoid dissection, identification of the anterior choroidal artery, choice of clip and clip placement is guided by image injection. Note the presence of an intravascular stent in the M1 segment of the MCA from a previous endovascular intervention.

Flow-diverter Hemodynamics

Neurosurgery

Video of a digital subtraction angiography series showing the effects of implantation of one or more pipeline stents on aneurysm hemodynamics. First, a sidewall aneurysm with a straight parent vessel prior to implantation of a flow diverter stent is shown. A turbulent, circulating, high velocity intra-aneurysmal flow profile can be seen, indicative of high wall shear stress. After implantation of a single stent a reduction of total contrast inflow and time until maximum contrast density is reached. In addition, the turbulent high-velocity aneurysm inflow is scrambled. After superimposition of a second pipeline embolization device a further decrease of inflow-speed and intra-aneurysmal contrast is observed.
Next, digital subtraction angiography series of a fusiform aneurysm model before and after implantation of FDS are shown. Before treatment, a straddling turbulent flow pattern is visualized at the distal aneurysm wall along the outflow tract. After telescoping implantation of two stents contrast flow into the aneurysm is reduced and a pulsatile pattern of contrast inflow through the stent mesh can be seen. Consequently, a reduction in total contrast inflow and time until maximum contrast density is reached. After superimposition of a third pipeline embolization device the contrast agent more homogeneously oozes out of the stent lumen into the aneurysm.
