&NA;The management of the case of a 9‐year‐old boy with progressive cognitive impairment due to arteriovenous fistulae at the apex of the inferior sagittal sinus is reported. This represents a unique location for an extraparenchymal deep central arteriovenous malformation. The patient underwent staged ablation of the lesion by surgery. The postoperative course was complicated by expansion of an aneurysmal vein of Galen undergoing thrombosis and hyperperfusion syndrome, but the patient ultimately made a satisfactory recovery.

摘要:

&NA;Toxic epidermal necrolysis is a rare but often fatal hypersensitivity reaction to numerous agents, including most anticonvulsants. The authors present a case of fatal phenytoin‐related toxic epidermal necrolysis in a patient who was given prophylactic anticonvulsant therapy after he sustained a moderately severe closed head injury. The typical course and current management of toxic epidermal necrolysis are reviewed, as are the indications for the prophylaxis of posttraumatic epilepsy. (Neurosurgery25:976‐978, 1989)

摘要:

&NA;Although head trauma is the leading cause of acquired trochlear nerve dysfunction, it receives little attention in the neurosurgical literature. A case is reported of closed head injury that resulted in a right superior oblique palsy in association with incoordination on the left side. Diagnostic imaging revealed a normal cranial computed tomographic scan and a left dorsal midbrain lesion on magnetic resonance imaging scan. The relevant anatomy is reviewed, as well as the action of the superior oblique muscle, its agonists and antagonists, and the clinical manifestations of superior oblique dysfunction. This case is one of the few we are aware of in which a relatively isolated trochlear nerve palsy is the result of a lesion that can be documented by diagnostic imaging, and the first in which the imaging modality is magnetic resonance imaging scan.

摘要:

&NA;We report a case of Balo's concentric sclerosis, a rare and acute variant of multiple sclerosis, which coexisted with an oligodendroglioma. The demyelinating lesion was clinically silent and was detected at necropsy. The pathogenesis of concentric sclerosis and the relationship of the demyelinating lesion to the evolution of the glial neoplasm is briefly discussed. (Neurosurgery25:982‐986, 1989)

摘要:

&NA;A 43‐year‐old woman presented with progressing signs of a space‐occupying brain stem lesion. A computed tomographic scan revealed a hyperdense process located in the pons. Magnetic resonance imaging confirmed the lesion, which had a reticulated core of increased and decreased signal intensity. Vertebral angiography did not show any vascular supply of the process. The patient was operated upon in the lateral park bench position. The lesion, being located close to the exit zone of the trigeminal nerve, could be removed totally with incision of the brain stem and atraumatic vaporization of the tumor tissue with the CO2laser. Despite the fact that the histopathological examination revealed a cavernous angioma the application of laser energy was judged to be extremely valuable for the surgical procedure. It was concluded that with proper selection of application mode and wattage the CO2laser may be used for extirpation of vascularized lesions also especially when situated in or close to deep lying vital structures of the brain.

摘要:

&NA;In a prospective study 144 adult patients with chronic subdural hematomas were randomly divided into three treatment groups after burr‐hole evacuation. The two commonly used procedures (external closed system drainage and aspiration and irrigation without any drainage) were compared to a modified technique: permanent subdural drain with subcutaneous reservoir. After the hematoma was washed out with saline solution, a silicon catheter with multiple perforations was introduced into the subdural cavity and connected to a Rickham reservoir, fixed in the frontoparietal burr hole. In patients who showed secondary deterioration or enlargement of the residual hematoma as proven by computed tomographic scan, the reservoir was punctured and the subdural fluid aspirated. The great advantage of this method is that it is practicable at the bedside as well as in the outpatient department, thus making it possible to reduce the number of additional operations. The incidence of symptomatic residual or recurrent hematoma was similar in all three groups. The reoperation rate was 4‐fold greater in the groups treated with conventional therapy, when compared to the group with the implanted system. At the same time there was no indication that the implantation of the drain was less safe, as judged by the incidence of seizures and infections. (Neurosurgery25:991‐996, 1989

摘要:

&NA;A case of a patient with a middle fossa mass that was considered to be either a metastatic lesion or a benign intracranial neoplasm is presented. The definitive management of the patient depended on a tissue diagnosis. A biopsy was obtained using a transfacial needle aspiration technique through the foramen ovale. The details of this procedure are described. (Neurosurgery25:996‐999, 1989)

摘要:

&NA;Although the transoral approach to the atlantoaxial region is generally an open surgical procedure, in patients in whom only tissue diagnosis is required, a needle biopsy can be done. In this paper a patient with a metastatic lesion in the second cervical vertebral body is presented, and the technique for needle biopsy of the second cervical body using stereotactic methods is described.

摘要:

&NA;During the 1985 annual meeting of the Congress of Neurological Surgeons in Honolulu, neurosurgical training and practice in India, Korea, Japan, and Australasia were discussed at the International Committee symposium. This article summarizes the information presented. India has about 300 neurosurgeons for a population of 650 million, while Japan has about 4.000 neurosurgeons and trainees for a population of 120 million. Korea has 424 neurosurgeons for a population of 41.5 million, and Australasia has 92 neurosurgeons and 19 trainees for 17.5 million people. Various other demographic, institutional, organizational, and economic aspects of neurological health care and delivery, education, and quality control are described. While financing and availability of adequate neurosurgical care remains a major problem in India, it appears that reducing the number of neurosurgical trainees remains, as it is in North America, a major issue in Japan and, to a lesser extent, in Korea. This problem, as well as certification of the quality of training, is being managed effectively in Australasia. (Neurosurgery25:1003‐1008, 1989)
