Endovascular treatment of transverse-sigmoid sinus dural arteriovenous fistulas (TSDAVFs) remains challenging because of their complex anatomic factors. The aim of our study was to evaluate the long-term efficacy and safety of endovascular treatment of TSDAVFs. ⋯ Favorable and durable outcomes were achieved with endovascular treatment of TSDAVFs. TSDAVFs with cortical venous reflux carry a high risk of hemorrhage and require curative treatment.

With the introduction into the neurosurgical practice of minimally invasive methods using endoscopic techniques, it became possible to effectively remove hard-to-reach tumors, including central tumors of the anterior region of the posterior cranial fossa. ⋯ The endoscopic endonasal transclival approach can be used to obtain access to centrally located skull base tumors. This approach allows for a radical and low-risk removal of various skull base tumors of central localization that, until recently, were considered to be almost inoperable.

Significance of Provocative Perfusion Computed Tomography for the Evaluation of Bow Hunter's Syndrome.
Bow hunter syndrome (BHS) is a rare vascular phenomenon of vertebrobasilar insufficiency caused by dynamic stenosis of the vertebral artery (VA) by osteophytes, fibrous bands, or disk herniation with neck rotation. We present a rare case of a patient with bilaterally patent VAs on neutral imaging and bilateral dynamic compression of VA with left head rotation. ⋯ Although dynamic angiography is the gold standard for diagnosis of BHS, cerebral angiography could be invasive and risky. Provocative test using perfusion computed tomography scan is a simple and noninvasive method to assess BHS on an outpatient basis.

An academic genealogy describes mentoring relationships in an academic discipline. In this study, we outline an academic genealogy of neurosurgery department chairs in the United States beginning with the founding members of the field. ⋯ The academic genealogy in this study allows for any neurosurgeon trained in the United States to put his or her training into historical context. It also provides a reference for bibliographic research to quantitatively describe the influence of individuals and institutions on the field.

To discuss lessons learned from an initial lateral lumbar interbody fusion (LLIF) experience with a focus on evolving surgical technique, complication avoidance, and new motor and sensory outcomes after implementation of a modified surgical approach. ⋯ The adoption of an exclusive mini-open muscle-splitting approach with first-look inspection of the lumbosacral plexus nerve elements may improve motor and sensory outcomes in general and the incidence of postoperative groin/thigh sensory dysfunction and psoas-pattern weakness in particular.
