    Traumatic arteriovenous fistula treated by superselective embolisation with microcoils: case report (1995)

    Notizen: Abstract A 27-year-old man with a traumatic direct dural arteriovenous fistula (DAVF) was treated using embolisation microcoils. He had suffered blunt trauma to the head while drunk and was aware of no neurological deficit. A few days after the accident, however, he noticed a bruit in the right temple. Angiography demonstrated a direct DAVF fed by the right middle meningeal artery and draining into a right temporal dural vein and the ipsilateral cavernous sinus. A Tracker-18 catheter was passed without difficulty through the fistula and the draining vein was then embolised from distal to proximal with microcoils, and finally the fistula was occluded with microcoils, resulting in total obliteration of the fistula. Immediately after the embolisation, the patient could no longer hear the bruit. Thus, when a microcatheter can be introduced into the draining vein, microcoils can be used as emboli in the treatment of direct DAVF.

    Cervical Infarction Associated with Vertebral Artery Occlusion due to Spondylotic Degeneration: Case Report (1998)

    Notizen: Summary  Cases of cervical infarction with clearly documented evidence of the underlying aetiology and associated neuroradiological abnormalities have not been frequently reported. A rare case of cervical infarction caused by midvertebral artery occlusion due to spondylotic degeneration of the spine is described. The most probable aetiological factor affecting this disease entity, and the usefulness of magnetic resonance imaging in the detection of this rare lesion, are briefly discussed.

    Light-intensity dependence in photocatalytic decomposition of water over K4Nb6O17 catalyst (1994)
    Springer
    Catalysis letters 28 (1994), S. 417-422

    Notizen: Abstract We have measured, for the first time, the light-intensity dependence in photocatalytic decomposition of water over K4Nb6O17 In higher light-intensity region, the rate of reaction is proportional to the square root of the light intensity. In lower light-intensity region, on the contrary, the rate is almost linearly proportional to the light intensity. We propose a reaction model whose main path of the reaction loss is the recombination of the charges generated under b and -gap radiation. This model describes the light-intensity dependence of this reaction well.
