Although there are many studies on ischemic brain damage in the gerbil, which is a good model of transient cerebral ischemia, studies on neuronal damage according to the duration of ischemia-reperfusion (I-R) time are limited. We carried out neuronal damage in the gerbil hippocampus after various durations of I-R (5, 10, 15 and 20 min) using Fluoro-Jade B(More)
OBJECT Outcomes of 1019 brachial plexus lesions in patients who underwent surgery at Louisiana State University Health Sciences Center during a 30-year period are reviewed in this paper to provide management guidelines. METHODS Causes of brachial plexus lesions included 509 stretches/contusions (50%), 161 plexus tumors (16%), 160 thoracic outlet syndromes(More)
OBJECTIVE Iatrogenic injury to the spinal accessory nerve is not uncommon during neck surgery involving the posterior cervical triangle, because its superficial course here makes it susceptible. We review injury mechanisms, operative techniques, and surgical outcomes of 111 surgical repairs of the spinal accessory nerve. METHODS This retrospective study(More)
OBJECTIVE Cubital tunnel syndrome is the second most common entrapment neuropathy of the upper extremity. Although many different operative techniques have been introduced, none of them have been proven superior to others. Simple cubital tunnel decompression has numerous advantages, including simplicity and safety. We present our experience of treating(More)
OBJECT To improve the safety of dura repair in neurosurgical procedures, a new dural material derived from silk fibroin was evaluated in a rat model with a dura mater injury. METHODS The authors prepared new, transparent, artificial dura mater material using silk fibroin from the silkworm, Bombyx mori. The cytotoxic and antiinflammatory effects of the(More)
OBJECTIVE Posture induced common peroneal nerve (CPN) palsy is usually produced during the prolonged squatting or habitual leg crossing while seated, especially in Asian culture and is manifested by the onset of foot drop. Because of its similarity to discogenic foot drop, patients may be diagnosed with a lumbar disc disorder, and in some patients, surgeons(More)
Visual loss is one of the ocular symptoms resulting from a carotid cavernous fistula (CCF), but has rarely been reported as the sole manifestation in CCF. Visual impairment is known to be associated with a poor outcome unless timely intervention is employed. Herein, the authors report a patient with bilateral rapid progressing visual loss as a sole(More)
OBJECTIVE The authors reviewed clinical and radiological outcomes in patients with three column injury of the cervical spine who had undergone posterior cervical fixation using Nitinol shape memory alloy loop in the anterior-posterior combined approach. MATERIALS Nine patients were surgically treated with anterior cervical fusion using an iliac bone graft(More)
OBJECTIVE The study examined the difference in the incidence of symptomatic cerebral vasospasm with magnesium supplementation in aneurysmal subarachnoid hemorrhage (SAH) in a Korean population. METHODS This retrospective analysis was performed in 157 patients diagnosed with aneurysmal SAH from January 2007 to December 2011 at a single center. Seventy(More)
OBJECTIVE Neuralgic amyotrophy (NA) is a distinct clinical syndrome that is characterized by the acute onset of shoulder and arm pain, weakness, and sensory loss. The purpose of this study was to assess the clinical characteristics of NA and to determine appropriate diagnostic modalities. METHODS We reviewed the medical and radiologic records of 10(More)
