BACKGROUND Previous reports of the efficacy of percutaneous pulsed radiofrequency have been confounded by fewer case numbers, poor patient selection, and limited data on cervical or lumbar radicular pain. We used percutaneous pulsed radiofrequency for cervical and lumbar radicular pain, and the study has more than 100 cases for the analysis of the efficacy(More)
Neural progenitors cells are capable of promoting neurogenesis after ischemic stroke in the adult mammalian brain; however the function of these cells and their fate is still not clear. Therefore the purpose of this study investigated the relationship between neural progenitors and reactive astrocytes after middle cerebral artery occlusion (MCAO). Brain(More)
OBJECT The authors assessed the effectiveness of percutaneous pulsed radiofrequency treatment for providing pain relief in patients with chronic low-back pain with or without lower-limb pain. METHODS Data were obtained in 127 patients who had chronic low-back pain with or without lower-limb pain due to a herniated intervertebral disc or previous failed(More)
BACKGROUND We report 8 rare cases of paired ANs involving fenestrated vertebrobasilar junction and demonstrate the flow patterns of the paired ANs by qualitative CFD analysis in 5 cases. METHODS Two-dimensional and 3-dimensional angiographic features of 8 cases were reviewed. Nine patient-specific geometries of CFD models in 5 cases were created for flow(More)
Conventional designs of an above-knee prosthesis are based on mechanisms with mechanical properties (such as friction, spring and damping coefficients) that remain constant during changing cadence. These designs are unable to replace natural legs due to the lack of active knee joint control. Since the nonlinear and time-varying dynamic coupling between the(More)
BACKGROUND Civilian gunshot wounds to the brain are relatively rare, and a much-neglected subject in Taiwan. We present our experience with 16 patients who sustained gunshot wounds to the brain, and then identify factors determining the respective outcomes. METHODS From 1988-2002, data from 16 patients with civilian gunshot wounds to the brain, who were(More)
Carotid artery stenting is commonly used to treat carotid artery stenosis. However, carotid in-stent restenosis remains a challenging problem. Herein, we report a difficult case of recurrent severe carotid in-stent restenosis with total contralateral internal carotid artery occlusion treated with repeat drug-eluting balloon inflations. The outcome after one(More)
Morphologic characteristics of angiographic doughnut-shaped aneurysms of the intracranial internal carotid artery (ICA) have been rarely reported in the literature and were discussed only radiologically. In this case, surgical clipping was performed, and the specimen from the aneurysm was examined to correlate the pathologic findings and morphologic(More)
