Efficacy of intraoperative monitoring of transcranial electrical stimulation-induced motor evoked potentials and spontaneous electromyography activity to identify acute-versus delayed-onset C-5 nerve root palsy during cervical spine surgery: clinical article.

Object: Deltoid muscle weakness due to C-5 nerve root injury following cervical spine surgery is an uncommon but potentially debilitating complication. Symptoms can manifest upon emergence from anesthesia or days to weeks following surgery. There is conflicting evidence regarding the efficacy of spontaneous electromyography (spEMG) monitoring in detecting evolving C-5 nerve root compromise.

Efficacy of neurosurgery resident education in the new millennium: the 2008 Council of State Neurosurgical Societies post-residency survey results.

Background: Neurosurgical residency training paradigms have changed in response to Accreditation Council for Graduate Medical Education mandates and demands for quality patient care. Little has been done to assess resident education from the perspective of readiness to practice.

Objective: To assess the efficacy of resident training in preparing young neurosurgeons for practice.

Computer modeling of cerebral blood flow following internal carotid artery occlusion.

It is difficult to predict the adequacy of the collateral blood flow in patients who undergo internal carotid artery occlusion. In order to address this difficulty, the authors have created a computer model of the cerebral circulation. This model features individualized simulations of the Circle of Willis and its afferent and efferent branches which can predict changes in flow that will occur during internal carotid artery occlusion.

Tetrahydrobiopterin synthesis and inducible nitric oxide production in pulmonary artery smooth muscle.

Partial callosal resection for pericallosal aneurysms.

The surgical treatment of aneurysms that arise at the origin of the pericallosal artery is technically difficult. This report describes a technique that improves the exposure of the proximal vasculature during a craniotomy for pericallosal aneurysms. A portion of the corpus callosum was resected in two patients before the manipulation of their aneurysms.

Spontaneous spinal epidural hematoma.

Two cases of the spontaneous occurrence of spinal epidural hematomas of the high thoracic area are reported. Both acute and subacute presentations of paraplegia are represented. Neither patient had experienced any significant antecedent trauma.

Meningioma associated with aneurysm and subarachnoid hemorrhage: case report and review of the literature.

A patient presented with spontaneous subarachnoid hemorrhage after a prolonged episode of coughing. A preoperative computed tomographic (CT) scan confirmed subarachnoid hemorrhage, but demonstrated no other lesion. Arteriography revealed an ophthalmic artery aneurysm.
