This video describes the schematic form of the intraoperative manipulation and reduction process of the C1-2 dislocation and basilar invagination. After opening the facet joint, C1 lateral mass and C2 pedicle screws were inserted in both sides. Then, two rods were connected bilaterally. When the rods were gradually fastened with the screws, the screw-rod system distracted the C1 backward and pushed the C2 downward and forward, thus achieving the reduction.

A 29-year-old male patient presented with back and radiating pain in both legs. MRI shows large disc herniation at the L4-5 level.
For successful percutaneous endoscopic lumbar discectomy, a working cannula should first be located with herniation. The left side is caudal side, right side is cranial side, 6 o’clock direction is toward the nucleus pulposus, and 12 o’clock is toward the epidural space. Second, we make a working space with the removal of disc tissue using a side-firing laser and forceps. We then release the annular anchorage with the laser. Third, we catch a disc fragment and pull the disc fragment by twisting the forceps.
After removal of the disc fragment, we find the torn annulus and check the epidural space. The torn annulus is shrunk by laser and bipolar coagulator.
After the PELD, the symptoms improved and postoperative MR shows good decompression.

We present a 65-year-old male with recurrent skull base chordoma. The patient had undergone several endoscopic skull base resections and radiation therapy due to multiple recurrence. Most recent MRI showed aggressive recurrence of the tumor invading the skull base, ethmoid sinus, cavernous sinus and right orbit. He underwent a radical transfacial, transmaxillary resection of the tumor and orbital content. During the procedure the ICA was injured. Immediate cerebral angiogram showed stenosis and possible dissection of the cavernous ICA but with adequate distal flow. The next day, the patient experienced progressive left hemiparesis. A repeat cerebral angiogram showed worsening of the stenosis with minimal distal flow. Endovascular therapy failed. The patient did not pass the balloon test occlusion. An urgent cerebral revascularization procedure was recommended. The patient underwent a high-flow ICA-MCA bypass with a radial artery graft. Intraoperative indocyanine green angiogram showed adequate patency of the bypass. The patient remained neurologically intact. A postoperative cerebral angiogram 24-48hrs after the procedure showed adequate cerebral blood flow. The arterial graft had a focal stenosis that required balloon angioplasty.

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.

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.

This video summarizes a dural splitting craniocervical decompression procedure for Chiari I without syringomyelia. The goal of surgery for Chiari 1 malformation is to restore normal cerebral spinal fluid dynamics at the craniocervical junction. Traditionally, shrinkage or even resection of the cerebellar tonsils has been advocated. More recently, simple duraplasty without manipulation of the intradural contents or even extradural decompression have been undertaken. A dural splitting decompression procedure in a 17-year-old male who presented with medically refractory, unremitting and progressive suboccipital headaches is described.

This video demonstrates the minimally invasive approach to intradural tumors using the transmuscular dilating tubes with an oblique angle to the spine and a hemilaminotomy using the high speed drill. This allows preservation of the spinous processes, inter- and supraspinous ligaments and hemilamina on the contralateral side, while not compromising the microsurgical technique required for tumor dissection, mobilization and resection. Thus, we feel that this technique offers distinct advantages to the patient through a reduction in tissue trauma with no disadvantageous implications for tumor removal.
