STUDY DESIGN: Prospective case series study. PURPOSE: Description of the outcome of stand-alone cervical cages for single and multilevel cervical degenerative spine disease. OVERVIEW OF LITERATURE: The aim of anterior cervical discectomy and fusion (ACDF) for cervical spine disease is to improve patient symptoms and spine stability and restore lordosis. Locking stand-alone cages were developed with the goal of minimizing soft tissue disruption anterior to the vertebrae and reducing the profile of the construct by avoiding an anterior plate, thereby maximizing ACDF benefits. METHODS: This study comprises a case series of patients surgically treated between July 2015 and February 2018 who received single or multilevel ACDF with a zero-profile stand-alone cervical cage. Surgical and clinical preoperative evaluation and surgical outcomes were evaluated using pre- and postoperative Nurick, Visual Analog Scale (VAS), Neck Disability Index (NDI), Japanese Orthopedic Association (JOA) score for myelopathy scales, cervical Cobb angles, postoperative surgical complications, and fusion and subsidence rates. RESULTS: Fifty-three patients underwent ACDF; the mean age of these patients was 58.8 years, and their preoperative VAS, NDI, and JOA scores were 8.1, 31.6, and 15.3, respectively. The preoperative Cobb angle was 30.7°. Forty-five percent of patients had one-level, 54.7% had two-level, and 13.2% had three-level procedures. On preoperative magnetic resonance imaging, foraminal stenosis was present in 94.3% of patients, whereas medullar stenosis was present in 41.5%. The rate of complications was 5.7%: two patients had postoperative dysphagia (3.7%), and one patient had a surgical site hematoma. Mean postoperative follow-up time was 6.7 months; postoperative VAS, NDI, and JOA scores were 2.4, 15.9, and 15.8, respectively. Postoperative Cobb angle was 35.9°, fusion rate was 84.9%, and subsidence rate was 11.3%. CONCLUSIONS: ACDF with zero-profile stand-alone cervical devices is an excellent option for cervical degenerative disc disease of one, two, and three levels, with similar results reported when using ACDF with either cage or plate.

Posterior Cerebral Artery aneurysms are scarce, yet its territory is frequently associated to large and giant aneurysms. Treatment is mostly a binary option between microsurgical clipping and endovascular coiling. Hybrid approaches are an option too, whereas innovation with less frequent techniques such as endoscope-controlled and endoscope-assisted procedure may provide a safer surgical approach with same successful results. Hereby we report a case of a 53 years old male examined at the ER after presenting generalized seizures and altered state of consciousness. Upon arrival, neurological evaluation revealed homonymous right hemianopia. Computed tomography (CT) scan revealed a subarachnoid hemorrhage and left parieto-occipital intraparenchymal hemorrhage with intraventricular extension; computed tomography angiogram (CTA) revealed an aneurysm at the left posterior cerebral artery (PCA) in its P4 segment. We performed a vascular exploration with drainage of the occipital and intraventricular hematoma through a single endoscopic port through transulcal approach guided by neuronavigation, in addition to clipping and aneurysmectomy. The combination of microsurgical clipping with previous Endoport-guided endoscopic procedure may be a surgical-operative option that not only may facilitate the approach to the desired lesion, but also provides a safer surgical scenario.
