Introduction: Although frequently observed in magnetic resonance images, symptomatic thoracic disc herniations are rare. Surgical treatment is indicated when patients suffer from functional symptoms with no response to medical treatment, neurologic appear or worsen the event of myelopathy. Posterolateral approaches commonly accepted as for lateral and mediolateral non-calcified medial herniatio...

INTRODUCTION Patients with an unruptured intracranial aneurysm treated with coil embolization are routinely admitted to the intensive care unit (ICU) after the procedure; however, this practice is questionable. The purpose of this study was to determine if routine admission to the ICU is necessary for patients undergoing coil embolization of an unruptured intracranial aneurysm. METHODS We con...

BACKGROUND AND PURPOSE Large-vessel intracranial atherosclerotic stenosis carries a proved stroke risk of 8%-22% per year with "best medical therapy." The long-term clinical neurologic and angiographic outcomes of angioplasty and/or stent placement for intracranial atherosclerosis in a consecutive series of patients are presented. METHODS The demographics, procedural details, procedural outco...

BACKGROUND Expansive open-door laminoplasty is widely accepted as a reliable procedure for cervical myelopathy. However, one acknowledged complication is spring-back complication or closure of the door which may result in restenosis of cervical canal and neurologic deterioration. The study aimed for addressing our cervical open-door laminoplasty technique with sutures and bone grafts and subseq...

Intracranial subdural hematoma following spinal anesthesia is an infrequent occurrence in the obstetric population. Nevertheless, it is a potentially life-threatening complication. In the majority of the cases, the first clinical symptom associated with intracranial subdural bleeding is severe headache, but the clinical course may have different presentations. In this report, we describe the ca...

Brain sag is a rare but serious postoperative complication after craniotomy. It is a clinical entity that refers to severe cerebrospinal fluid hypovolemia causing acute neurologic decompensation and obtundation. The established treatment is trendelenberg positioning. We present 3 cases of severe brain sag in which patients developed acute neurologic deterioration unresponsive to conventional tr...

Polycythemia vera (PV) is a myeloproliferative disorder associated with neurologic sequelae. The most severe neurologic processes affecting patients with PV are thrombotic and hemorrhagic strokes. Few cases published in the medical literature describe developments of other neurologic symptoms, including papilledema, oculomotor nerve palsy, one-and-a-half syndrome, and trochlear nerve syndrome, ...

EXTRAMEDULLARY intrathecal granuloma formation is a rare complication of morphine administration via implanted drug delivery systems. We present a unique case of a granuloma adherent to the conus medullaris presenting as cauda equina syndrome. Practitioners should not assume that implantation of intrathecal catheters with their tips located at or below the conus medullaris will eliminate all ri...

Introduction. The lateral lumbar interbody fusion (LLIF) surgical approach has potential advantages over other approaches but is associated with some unique neurologic risks due to the proximity of the lumbosacral plexus. The present study analyzed complications following LLIF surgical approach using a novel single flat-blade retractor system. Methods. A retrospective data collection of patient...

STUDY DESIGN Retrospective review. OBJECTIVES Large compressive pseudomeningocele causing a major neurologic deficit is a very rare complication that is not well described in the existing literature. METHODS Institutional review board consent was obtained to study 2552 consecutive extradural spinal surgical cases performed by a single senior spinal surgeon during a 10-year period. The surge...
