    Autoperfusion balloon catheter for treatment of vertebral artery stenosis (1995)

    Notes: Abstract Percutaneous transluminal angioplasty (PTA) of the vertebral artery was performed with an autoperfusion balloon catheter in five patients. There were no complications in the form of embolic episodes or neurological deficits due to brain ischaemia during inflation. In critical cases with insufficient collateral circulation during temporary occlusion, the use of an autoperfusion balloon catheter may expand the indications for PTA in patients with ischaemic cerebrovascular disease.

    Effectiveness of intra-arterially infused papaverine solutions of various concentrations for the treatment of cerebral vasospasm (1997)

    Notes: Summary We evaluated the effect of intra-arterially infused papaverine solutions of various concentrations on cerebral vasospasm following subarachnoid haemorrhage. A total of 90 vascular territories in 46 patients with symptomatic cerebral vasospasm after subarachnoid haemorrhage were treated with intra-arterial infusions of papaverine. In all patients, papaverine was infused at the top of the internal carotid artery (ICA). Of the 90 vascular territories, 30 vascular territories in 14 patients were treated with an infusion of 0.1–0.2% (weight/volume) papaverine (Group 1), 30 vascular territories in 16 patients were treated with a 0.4% (w/v) papaverine infusion (Group 2), and 30 vascular territories in 16 patients were treated with an infusion of 0.8–2.0% (w/v) papaverine (Group 3). Among the three groups, we compared the vasodilatory effects of papaverine by assessing the angiographical and clinical improvements following the treatment. When 0.4% (w/v) papaverine was infused, 24 vascular territories (80%) were successfully dilated and 7 patients (44%) showed a marked reversal of neurological deficits due to vasospasm. Therefore, 80 mg/20 ml (0.4% (w/v)) papaverine infused over a 10-minute period proved to be a beneficial concentration. Transient focal neurological deficits due to the infusion of papaverine occurred in 1 Group 1 patient (7%), 1 Group 2 patient (6%), and 7 Group 3 patients (44%). Highly concentrated papaverine had a higher risk of temporary deterioration. In conclusion, the papaverine concentration of 0.4% (w/v) infused at the top of the ICA was a safe and adequate concentration for treating cerebral vasospasm.

    Intra-arterial infusion of papaverine combined with intravenous administration of high-dose nicardipine for cerebral vasospasm (1995)

    Notes: Summary The clinical effect of combination therapy with high doses of intravenous nicardipine and intra-arterial infusion of papaverine on symptomatic vasospasm after subarachnoid haemorrhage (SAH) was analysed retrospectively. In 66 of 122 patients who underwent early aneurysm surgery between 1990 and 1993, the intracranial haemodynamics were documented by transcranial Doppler (TCD) ultrasonography. 33 of these 66 patients received high dose nicar-dipine intravenously (Group I); the other 33 patients were not treated with calcium antagonists (Group II). Symptomatic vasospasm occurred in 6 Group I patients (18%) and in 13 (39%) in Group II patients. All 19 symptomatic patients received an intra-arterial infusion of papaverine; 15 patients (79%) responded well to this therapy and the symptoms were reversed quickly. Although the mean flow velocity (MFV) was not different between the two groups, it was reduced significantly after papverine infusion. Our retrospective analysis suggests that symptomatic vasospasm can be treated effectively with the combination of intravenous high dose nicardipine and intra-arterial infusion of papaverine, and that the correct timing of the infusions is crucial.

    Thermal decomposition and carbonization mechanism of poly-para-phenyleneoxadiazole (1990)
    Bognor Regis [u.a.] : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: Thermal decomposition and carbonization mechanism of poly-para-phenylene-1,3,4-oxadiazole were investigated using FT-IR, thermogravimetry, gas-analysis, XPS, 13C-CP/MASFT-NMR, and elemental analysis. At temperatures above 500°C, the decomposition reaction proceeds preferentially on the oxadiazole ring, eliminating p-aminocyanobenzene and p-dicyanobenzene. Formation of carbodiimide compounds and their coupling followed in residual compounds, whose products are important intermediates leading to a planar and polyconjugated nitrogen-containing (e.g., graphite-like) carbon precursor.
