Abstract Brainstem cavernous malformations are uncommon vascular lesions that require complex surgical approaches. The case described in this video involved a 23-year-old male who presented with repeated, symptomatic episodes of bleeding of pontomedullary cavernous malformation which was resected. The anterior petrosectomy approach is detailed in this video, highlighting middle fossa triangles and their boundaries as well as important safety techniques. Postoperative imaging depicted complete re...

Background Intracranial aneurysm formation after Gamma Knife radiosurgery (GKRS) is a rare complication that has only recently been reported in the literature. We report the case of a fatal distal superior cerebellar artery (SCA) aneurysm rupture in a woman treated twice with GKRS for trigeminal neuralgia along with a review of the literature regarding radiation-induced aneurysms. Case Description A 77-year-old white woman with a history of refractory right-sided trigeminal neuralgia treated wit...

Background Cervical spine degenerative disease is one of the main causes of myelopathy. Anterior cervical discectomy and fusion (ACDF) is the most common surgical procedure used to treat cervical myelopathy. Therefore, it is important to study pseudarthrosis rates after ACDF and correlate them with the graft used. Methods We performed a systematic review to evaluate the relationship between pseudarthrosis after ACDF and the interbody graft used. Results A total of 3732 patients were evaluated in...

The use of cortical bone trajectory (CBT) pedicle screws for posterior fixation and fusion seems to constitute a viable alternative for spinal procedures, with the potential to mitigate risks, be minimally invasive, and cause less tissue damage than the traditional technique. This review analyzes the literature regarding CBT according to the rate of evidence of articles and their main focus. CBT has proved to be a safe and viable option for screw fixation in spine surgery. Given the denser bone ...

Background Reversible cerebral vasoconstriction syndrome (RCVS) is a rare complication after carotid endarterectomy (CEA). Only a limited number of prior cases of RCVS have been reported after CEA for asymptomatic carotid stenosis. Case Description In this report we present an unusual case of RCVS associated with multifocal intraparenchymal hemorrhage, subarachnoid hemorrhage, subdural hematoma, and ischemic stroke after CEA for asymptomatic carotid stenosis. We review preexisting studies and dr...

Abstract Background Diffusion tensor imaging (DTI), functional MRI (fMRI), and intraoperative magnetic resonance imaging (iMRI) permit greater visualization and more accurate pre-surgical planning. Meta-analysis of these techniques for maximizing resection, post-operative functionality and survival may further validate purported strengths of these techniques compared to standard neuronavigation. Methods A systematic search of the PubMed database was conducted in line with the PRISMA guidelines f...

Abstract Objective Lumbar facet cysts are commonly seen in degenerative lumbar conditions causing stenosis and radiculopathy. Extraforaminal lumbar facet cysts are a rare entity and present a surgical challenge because of their location. Transforaminal endoscopic spine surgery is an emerging technique in spine surgery but has never been described as a treatment option for lumbar radiculopathy in the setting an extraforaminal lumbar facet cyst. Methods A technique for the transforaminal endoscopi...

Background To date, only a few documented cases exist of complete or near-complete paraplegia of the lower extremities following collapse of a vertebral body secondary to an aneurysmal bone cyst. We describe the preceding symptoms associated with this catastrophic event along with surgical management and recovery. Case Description A previously healthy, 13-year-old girl had experienced months of ongoing back pain with associated posture change. After collapsing at home in the bathroom, she was br...

Abstract Objective Calcified or ossified chronic subdural hematoma (CSDH), characterized by slowly progressing neurological symptoms, is a rarely seen entity that may remain asymptomatic for many years. Management of CSDH has improved dramatically in recent years thanks to advances in diagnostic tools, but there is still some controversy regarding the optimal treatment strategy. Methods In this systematic review, PRISMA guidelines were followed to query existing online databases between January ...

Tentorial dural arteriovenous fistulas are rare causes of intracranial hemorrhage and nervous tissue venous congestion. Due to their extensive arterial supply and difficult transvenous endovascular navigation, they are frequently managed microsurgically. Precise identification of the venous drainage, its retractorless exposition, and real-time verification of arteriovenous disconnection are the mainstays of surgery. We describe the case of 61-year-old man presenting with a cerebellar hematoma ca...
