Dural Traction A Possible Cause Of Hemodynamic Changes During Single Level Transforaminal Lumbar Interbody Fusion.
Lumbar spinal surgery may be associated with electrophysiologic and hemodynamic abnormalities during the procedure. ⋯ Anesthesia providers should be aware of electrophysiologic and hemodynamic abnormalities during lumbar spinal surgery and the need to respond appropriately with sympathomimetic or vagolytic interventions.

Keeping the operating field clean and visible is an important technique in neurosurgery. Continuous irrigation-suction (IS) of the surgical field is currently often done using devices available that are expensive and demand technical proficiency. We report a simple method of continuous IS using a widely available central venous catheter and a controlled suction cannula. ⋯ The proposed IS system could be surgeon friendly, easily manageable, yet cost-effective and efficient.

Cyclic Sciatica and Back Pain Responds to Treatment of Underlying Endometriosis: Case Illustration.
Multiple causes outside the spine can mimic spinal back pain. Endometriosis is an important gynecologic disorder, which commonly affects the lower region of the female pelvis and less frequently the spine and soft tissues. The lumbosacral trunk is vulnerable to pressure from any abdominal mass originating from the uterus and the ovaries. Therefore symptoms of endometriosis include severe reoccurring pain in the pelvic area as well as lower back and abdominal pain. ⋯ It is critical for any clinician who deals with back pain to at least consider the diagnosis of endometriosis in female patients who have a history of pelvic pain. The diagnosis of endometriosis should be considered in candidate patients by asking whether there is a significant hormonal cyclic nature to the symptoms, to prevent such unnecessary surgical adventures.

Intraoperative ultrasonography is widely used in neurosurgery for the management of intracerebral hematoma and brain tumor. However, the clinical value of this method in the surgery of cerebral arteriovenous malformations (AVMs) has not been reported. In this study, the application of intraoperative ultrasonography for AVM surgery was evaluated prospectively. ⋯ Microneurosurgery with intraoperative ultrasonographic image guidance was a safe, effective, and reliable method for identifying the afferent and efferent vessels and for confirming the complete resection of AVMs. These benefits of image-guided microsurgery were mostly apparent for deep-seated AVMs that were not visible on the surface of the brain.

Frameless Stereotactic Robot-Assisted Subthalamic Nucleus Deep Brain Stimulation: Case Report.
Electrode implantation for deep brain stimulation (DBS) can be performed in numerous ways, but the current "gold standard" is the use of frame-based systems for accuracy. Robotic stereotactic procedures, however, have gained increased interest because of their ease of use and reliability, but there could be concern about their safety in the United States as the result of recent lawsuits (e.g., the da Vinci Surgical System). We report the first DBS implantation performed using a robot (ROSA robotic device) approved by Food and Drug Administration for use in North America. ⋯ The advantages of robotic assistance in stereotactic procedures are as follows: 1) improved accuracy, 2) "arc-less" approach, and 3) minor adjustments can be made in multiple planes to the entry point without adjustment of a frame. The case demonstrates robotic stereotactic assistance viability as an alternative to traditional frame-based or frameless systems in U.S. hospitals.
