Neuroendovascular procedures can be challenging due to severe angulation of the cervical and cranial vessels. Typical approaches for overcoming this tortuosity involve using multiple telescoping catheter systems to provide proximal support for therapeutic device delivery. Although this approach can be effective, it does have limitations. ⋯ Although helpful in overcoming challenging anatomy, the Guidezilla guide extension catheter should be used with caution when used as a bailout device.

Unplanned 30-day readmissions after surgery are a source of patient dissatisfaction, monitored by the Centers for Medicare and Medicaid Services, have financial penalties for hospitals, and are publicly reported. Neurosurgical operations have a higher 30-day unplanned readmission rate after the index discharge than other specialties. After a simple initiative for a 48-72-hour postdischarge telephone call, there was an observed significant decrease in readmission rates from 17% to 8% in 7 months at Thomas Jefferson University. To better understand the role of postoperative telephone calls in this reduction, a retrospective evaluation over a longer period was performed. ⋯ Telephone calls and peridischarge efficient communication are needed after neurologic surgery. This approach decreased unplanned readmissions in certain instances without having a significant impact on neurosurgical patients.

To describe a simple variation of burr hole craniostomy for the management of chronic subdural hematoma (CSDH) that uses a frontal drainage system to facilitate timely decompression in the event of tension pneumocephalus and spares the need for additional surgery. ⋯ The described variation of burr hole craniostomy represents a low-cost and easy-to-implement technique that can be used for emergency decompression of tension pneumocephalus. It also has the potential to reduce reoperation rates and CSDH recurrence. Prospective controlled research is needed to validate this approach further.

Cerebrospinal fluid venous fistulas (CSF-VFs) are an uncommon, yet increasingly recognized, cause of spontaneous intracranial hypotension.1-5 The workup involves magnetic resonance imaging (MRI) of the brain with and without contrast and MRI of the neuroaxis without contrast before dynamic myelography, either computed tomography or digital subtraction.6 The present case of an older woman with symptomatic intracranial hypotension is notable for the specific appearance of CSF-VFs on digital spinal myelography (Video 1). Among her numerous perineural cysts, it was the "disappearing" or "empty" cyst from which the fistula originated. The diagnosis was made using a second lateral fluoroscopy view, not typically used in digital spinal myelography, which demonstrated emptying of contrast from the T6 perineural cyst into the segmental vein at this level, or the "empty cyst sign." The patient then underwent transvenous onyx embolization with resolution of her orthostatic headaches and improvement of contrast-enhanced MRI of the brain with the Bern score decreasing from 7 to 0 at 3 months of follow-up.7 Because transvenous embolization of CSF-VFs is a relatively new procedure, the long-term outcomes of the procedure are not yet known.

Two main surgical techniques are available for corpus callosotomy (CC): conventional microscopic CC and endoscopic CC.1 Microscopic CC is more familiar to neurosurgeons and allows three-dimensional visualization, but it requires a larger craniotomy and has a narrower visual angle in the deep part. Endoscopic CC has only recently been introduced to epilepsy surgery, but it is gaining increasing interest among epilepsy surgeons. The endoscope provides two-dimensional visualization and requires a camera as an additional instrument inserted into the surgical corridor. ⋯ In some cases, this procedure can take a long time. On the other hand, a posterior approach requires less interhemispheric arachnoid dissection, or sometimes none at all, due to the anatomy of the falx cerebri. These reasons have driven the development of a posterior approach for an endoscopic-alone technique.3 Here, we present a 5-year-old girl with medically intractable epileptic spasms that were diagnosed as infantile epileptic spasms syndrome, who underwent endoscopic total CC via a posterior approach to control her seizures (Video 1).
