    Notes: Summary A simple method of making a three-dimensional display model of recorded computerized tomography (CT) scan films is presented. The reconstructed display model provides useful information as to surgical approaches to intracranial mass lesions. The actual size and three dimensional shape of a lesion and its topographical relationship to surrounding brain structures are easily grasped by directly handling this model.

    Mortality study of patients with subarachnoid haemorrhage at University hospitals and their affiliated hospitals in Japan (1982)

    Notes: Summary This study was undertaken to examine the differences in aneurysm statistics between University hospitals where subacute or chronic patients are primarily treated and University-affiliated hospitals where both acute and chronic cases are also admitted. In each hospital group, the transition of the statistics in the last decade was studied. The purpose of this study was also to see if any conclusion could be drawn regarding the surgical treatment of acute cases. The death rate for all aneurysm cases admitted is 8% at University hospitals, whilst that at affiliated hospitals is roughly 30% during the 1970s. The operative death rate at the University hospitals is 3%, whilst that at affiliated hospitals is 16% which improved at one affiliated hospital to 8% in the 1980–1981 period. Morbidity also improved in the latest series in the affiliated hospital. These improvements are considered to be due to the change of operative and postoperative policies for acute cases to : limited surgical indications for grade IV patients, extensive cisternal clot removal at the time of surgery, and oral administration of Ticlopidine, a new antiplatelet agent.

    Clinical study of brain retraction in different approaches and diseases (1987)
    Springer
    Acta neurochirurgica 87 (1987), S. 134-139 
    Details
    ISSN: 0942-0940
    Keywords: Operative approach ; brain retraction ; tumour ; aneurysm
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Pressure of brain retraction was measured with a strain gauge spatula in 31 cases of 21 tumours and 10 aneurysms. They were operated on via different approaches: subfrontal (10 cases), interhemispheric (5), subtemporal (7) and suboccipital (9). The patients' age ranged from 11 to 74 years (average 50). The recorded data were averaged for every 5 minutes and divided into two groups: the first was data taken in the initial stage during the approach to the lesions, and the second were those taken during procedures at and around the lesion. Significant difference in the pressure among different approaches was found in the tumour group approached by the subtemporal route compared with other routes (p 〈 0.005). The retraction pressures in the tumour cases were higher during the approach (31±15.5 torr) than during the main procedure (12±9.2 torr) (p 〈 0.025). On the other hand, the pressures in the aneurysm cases were the reverse, being lower during the approach (22±15.2 torr) than during the main procedure (38±17.7 torr) (p 〈 0.01). Early-stage operations for aneurysm required a higher retraction pressure than delayed operations.

    Subdural fluid collections following transcortical approach to intra- or paraventricular tumours (1989)
    Springer
    Acta neurochirurgica 99 (1989), S. 20-25 
    Details
    ISSN: 0942-0940
    Keywords: Hydrocephalus ; intraventricular tumour ; postoperative complication ; subdural fluid collection
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Subdural fluid collections appeared in 15 cases (39%) after removal of 38 intra- and paraventricular tumours in the third or lateral ventricle through 18 frontal and 20 parietal transcortical approaches. Transient fluid collections which disappeared within 2 weeks occurred in 6 cases (16%) and persistent ones in 9 cases (24%). Four of the 9 cases (11%) of collections required surgical treatment because of positive clinical signs and symptoms. Two cases had expansive fluid collections and the other two contained subdural haematomas at surgery. The risk factors likely to contribute to a persistent collection were preoperative ventriculomegaly (frontal horn index 〉 0.38) and a frontal transcortical approach. A symptomatic collection should be considered as a potential complication of the transcortical approach to intraventricular tumours and some methods should be devised to prevent it when intra- or paraventricular tumours with ventriculomegaly are removed.

    Innervation of dog ciliary ganglion (1982)
    Springer
    Histochemistry and cell biology 76 (1982), S. 295-301 
    Details

    Topics: Biology , Medicine
    Notes: Summary There are species differences with regard to the composition of the ciliary ganglion. For instance, in rabbits and cats it consists solely of oculomotor nerves and has no sympathetic or sensory innervation. The purpose of this study is to clarify the participation of these nerves in the ciliary ganglion of the dog by histochemical methods. Cholinesterase (ChE) activity was studied by Karnovsky's method and catecholamine fluorescence by the glyoxylic acid method. Furthermore, the origins of the respective nerves were investigated by a serial preparation method, involving unilateral cervical sympathectomy and tracer dye injection in the ganglion. The results obtained were: (1) Ciliary ganglion cells showed intense ChE activity. Oculomotor nerve fibers leading to the ganglion showed moderate ChE activity, while the reaction in the short ciliary nerves was strong. (2) Aminergic nerves were present in the intercellular space of the ciliary ganglion, and bilateral or central innervation was suggested by the results of cervical sympathectomy. (3) Connection between the ciliary and trigeminal ganglia was proved by the dye tracer study. The results show that the ciliary ganglion in dogs is composed of oculomotor, trigeminal and sympathetic nerves.

    Histochemical studies on the postnatal development of autonomic nerves in mice cerebral arteries (1981)

    Notes: Summary Postnatal development of autonomic nerves of major cerebral arteries was histochemically studied in mice from one day to five months of age. For demonstration of aminergic nerves the glyoxylic acid method was used, while for cholinergic nerves Karnovsky and Roots' technique was utilized consecutively on the same whole mount preparations. The results obtained were as follows: 1) In one-day-old mice a few aminergic nerves were seen while cholinergic nerves were scarcely observed. The cholinergic nerves were clearly observed in one-week-old mice. Then, both nerves increased rapidly in the first 2 weeks with a slight delay of maturation in the latter. They completed development between 3 and 4 weeks. 2) Longitudinal and circular distributional patterns were observed for the both nerves; the former pattern developed earlier than the latter.

    Adrenergic and cholinergic innervation of rat cerebral arteries (1981)
    Springer
    Histochemistry and cell biology 70 (1981), S. 129-138

    Topics: Biology , Medicine
    Notes: Summary A consecutive demonstration of both aminergic and cholinergic nerves of rat cerebral arteries was carried out on whole mount preparations. For demonstration of aminergic nerves the glyoxylic acid method was used, while for cholinergic nerves Karnovsky's technique was utilized consecutively. This procedure provided a highly sensitive and reproducible demonstration of the two systems on the same specimen. The results obtained were as follows: 1) Aminergic and cholinergic nerves were distributed densely in the proximal portions of the major cerebral arteries examined. They were dense in the arteries of the anterior circulation and sparse in the posterior circulation. Each nerve had two different patterns, i.e. circular and longitudinal. Both circular and longitudinal patterns were observed in the proximal portions of the arteries, while in the distal portions, longitudinal fibres were predominantly present. 2) Superior cervical ganglionectomy produced no change in cholinergic nerve distribution, while it caused decreased density of aminergic nerves on the ipsilateral side on the arteries of the anterior circulation. The contralateral anterior cerebral arteries were partially affected. Bilateral sympathectomies abolished aminergic nerves in all arteries except the vertebral artery.
