This study aimed to investigate the curative effect and costs of surgical and gamma knife treatments on intractable epilepsy caused by temporal-hippocampal sclerosis. The subjects comprised patients who suffered from intractable epilepsy caused by temporal-hippocampal sclerosis and received treatment in the Department of Neurosurgery of our hospital between 2010 and 2011. After obtaining their ...

BACKGROUND The predominant treatment modality for meningioma is surgical resection. However, gamma knife radiosurgery is also an important treatment modality for meningioma that is small or cannot be completely removed because of its location. In this study, we evaluated the effectiveness and long-term results of radiosurgical treatment for meningioma in our institution. METHODS We studied 62...

Following the remarkable success of catheter based ablation techniques in curing regular supraventricular tachycardias, the attention of the electrophysiological community has turned upon atrial fibrillation based on the assumption that if surgical incisions with a knife can be duplicated by point by point lesions, a catheter based technique should provide results equivalent to the Maze procedu...

BACKGROUND We present a rare case of an intraparenchymal nonmissile penetrating spinal injury (NMPSI) occurring at the T11 level in a patient presenting without neurological deficit. CASE DESCRIPTION The patient sustained a knife wound that penetrated the lamina without incurring bony injury and entered the spinal cord at the T11 level. During surgery, the intramedullary penetration of the co...

Introduction The Gamma Knife system is designed solely for non-invasive treatment of brain disorders, and it benefits from stereotactic surgical techniques. Dose calculations required in the system are performed by GammaPlan code; in this code, brain tissue is considered uniform. In the present study, we evaluated the effect of Gamma Knife system on the obtained dose through simulating a real ...

Objective The aim the project virtual development needle-knife surgical device useful for minimally orthopaedic procedures and other procedures. Method Three different needle devices were compared. One base model 1 two are e...

We have developed a liver surgery support system that uses two depth cameras and measures positional relationships between a surgical knife and a liver in real time. In this report, the overview of our system, the method for depth camera calibration, the estimation for knife tip positioning, and some experimental results are described.
