OBJECTIVE Although several clinical applications of transpedicular screw fixation in the cervical spine have been documented recently, few anatomic studies concerning the cervical pedicle are available. This study was designed to evaluate the anatomy and adjacent neural relationships of the middle and lower cervical pedicle (C3-C7). The main objective is to(More)
CT-guided stereotactic percutaneous destructive procedures, i.e. percutaneous cordotomy, trigeminal tractotomy, and extralemniscal myelotomy, have been routinely used for the treatment of localized intractable pain in malignancy since 1987. In 67 cases if local pain due to malignancy, CT guided percutaneous cordotomy was performed and in 97% complete pain(More)
A patient with an intradiploic epidermoid cyst of calvarium was presented. Head injury that may cause the inclusion of epidermal cells into the diploe of the bone was present in his medical history. Skull radiographs and cranial magnetic resonance imaging (MRI) demonstrated the tumor. The tumor was totally removed and the patient was discharged free of(More)
BACKGROUND There are few studies carried out to reveal lumbar arterial anatomy. The studies of vascular anatomy of the lumbar zone are usually based on the angiographic imaging methods and barium injected radiographic sections of human specimens. METHODS Upon the recent breakthroughs in the microscopic anatomic dissections, the vascular structure of this(More)
The efficacy of sodium nitroprusside in resolving cerebral vasospasm was evaluated with multicisternal injections. Twelve animals received fresh, unheparinized arterial blood via three injections (15 ml total) into the cisterna magna. Selective vertebral arteriography was performed on Day 0, and blood injections were performed on the second and third days(More)
BACKGROUND Stereotactic percutaneous pain procedures, percutaneous cordotomy, trigeminal tractotomy, and extralemniscal myelotomy are routinely performed with computed tomography (CT) guidance. This new imaging technique enables one to measure the spinal cord diameters for each patient uniquely. Significant differences have been recognized between the(More)
Percutaneous bilateral cordotomy performed using conventional techniques may cause the patient to develop sleep-induced apnea due to bilateral destruction of the ventrolateral reticulospinal tract. Computerized tomography (CT)-guided percutaneous cordotomy using a newly designed needle electrode system has the advantages of safe, selective, and controlled(More)
Extralemniscal myelotomy (ELM) is a procedure performed at the cervicomedullary junction of the spinal cord in which the central cord is lesioned to treat intractable pain. The neurophysiological mechanism of pain relief after ELM remains unclear. The authors present a series of 14 patients with intractable cancer pain who were managed by CT-guided,(More)
Spinal cavernous angiomas frequently accompany to cranial cavernous angiomas. Multiple spinal cord cavernous angiomas are very rare and to authors knowledge, only one case has been described having multiple intramedullary cavernous angiomas without cranial involvement until now. In this report, we present a case with acute paraplegia who had thoracic and(More)
STUDY DESIGN Case report. OBJECTIVES A rare case of anterior cervical second root traumatic neuroma with no history of trauma is reported, and possible etiology is discussed. SUMMARY OF BACKGROUND DATA Traumatic neuroma is the reactive, nonneoplastic proliferation in the injured nerve. Several atypical locations of traumatic neuroma have been reported.(More)
