Thus study was a retrospective cohort analysis. Anterior cervical discectomy and fusion (ACDF) has been the gold-standard procedure for single-level degenerative disc disease (DDD). Recently, cervical disc arthroplasty (CDA) has become increasingly prevalent as an alternative intervention. ⋯ We found no difference in health care utilization between ACDF and CDA procedures for DDD 5 years after surgery. Also, there was no difference in reoperation rates during the study period. ACDF resulted in significant reduction in overall opioid use after versus before procedure.

Case Reports
Facial nerve schwannoma complicated by acute hemorrhage post treatment with stereotactic radiosurgery.
Facial nerve schwannomas (FNSs) are rare benign tumors that arise from Schwann cells of the facial nerve. FNSs are similar to vestibular schwannomas in many aspects, yet their infiltrative nature into the facial nerve fascicles warrants a more conservative management approach. In the last decade, stereotactic radiosurgery (SRS) has shown promise in stabilizing or shrinking FNSs. ⋯ SRS has led to better facial nerve function and outcomes and is currently considered a reasonable alternative to microsurgical resection in patients with FNSs. This is the first report to our knowledge of an acute, life-threatening hemorrhage after SRS in a patient with FNS.

Spinal arteriovenous fistulas (AVFs) are a rare entity that can have devastating neurologic outcomes. Currently, these lesions are treated via open microsurgical resection or transarterial embolization with good success. However, some patients cannot be treated with a minimally invasive endovascular technique secondary to difficulty catheterizing their vascular anatomy. Our aim is to present a case of balloon-assisted Onyx embolization of a spinal AVF. ⋯ We present a challenging case in which normal embolization microcatheters were unable to navigate difficult anatomy, but we were able to gain access and obliterate the fistula by using a balloon catheter.

A 39-year-old man presented with a large left paramedian frontal lobe intracerebral hemorrhage. Computed tomography angiography and magnetic resonance imaging revealed a tangle of vessels arising from the anterior cerebral arteries (ACAs) and dilated draining veins entering the superior sagittal sinus. Angiography confirmed a Spetzler-Martin grade 3, supplemented 2 arteriovenous malformation (AVM) with predominant supply from branches of the left ACA with superficial and deep drainage (Video 1). ⋯ Once the AVM was disconnected and skeletonized from the A2s, the draining vein was clipped and the nidus was removed. Indocyanine green angiography confirmed patency of the A2s and pericallosal arteries. Postoperative angiography demonstrated no residual shunting, and the patient was discharged in good condition.

Research has shown that the optic nerve sheath diameter (ONSD) is a good predictor of intracranial pressure (ICP) and may predict the need for surgery in patients with head injury. The objective was to test the value of ONSD in predicting the requirement for surgery in patients with traumatic brain injury (TBI). ⋯ ONSD measured via head computed tomography correlates with ICP and can predict the requirement for surgery in patients with TBI following admission to the emergency department.
