    Notes: Abstract A Doppler sonographic guidewire was used to monitor incremental changes in draining vein (DV) flow during endovascular occlusion of a complex vertebral arteriovenous fistula (AVF) in a patient with neurofibromatosis type 1. Transvenous monitoring of average peak velocity (APV) and the maximum-minus-minimum peak velocity (MxPV-MnPV) demonstrated a progression from a highly pulsatile, fast flow before embolization to a nonpulsatile, slow flow indicating a successful occlusion of the AVF (hemodynamic endpoint of treatment). Prior to this, apparent angiographic occlusion of the AVF was thought to signify a successful endpoint; however, persistently elevated values for APV and MxPV-MnPV in the DV signalled the presence of an additional contralateral arterial contribution. Transvenous monitoring of flow velocity appears to be ideally suited to establishing a hemodynamic endpoint of embolotherapy in the presence of complex arteriovenous shunting, as may occur with the vasculopathy of neurofibromatosis.

    Description / Table of Contents: Summary The substitution reduction waves of copper(II)-EGTA and copper(II)-EDTA chelates were investigated with differential pulse and tast polarographic methods. The reduction wave of copper(II)-EGTA chelate shifts to more positive potential in the presence of lanthanum(III) and a new differential pulse peak appears. The peak height increases linearly with increasing concentration of lanthanum(III) between 5 and 25 μM. When the copper(II)-EDTA chelate is reduced in a supporting electrolyte containing no buffer solution, lanthanum(III) gives a substitution reduction peak, but in acetate buffer solution the lanthanum(III) peak disappears.
    Notes: Zusammenfassung Die Substitutionsreduktionswellen des Kupfer(II)-EGTE- und des Kupfer(II)-EDTE-Chelats wurden mit Hilfe der Differential-Puls- und der Tast-Polarographie untersucht. Die Reduktionswelle des Kupfer(II)-EGTE-Chelats verschiebt sich in Gegenwart von Lanthan(III) zu positiverem Potential und ein neuer Differential-Puls-Peak erscheint. Die Peakhöhe nimmt mit steigender Lanthanionkonzentration zwischen 5 und 25 μM linear zu. Wenn Kupfer(II)-EDTE-Chelat im pufferfreien Leitelektrolyt reduziert wird, gibt Lanthan(III) einen Substitutionsreduktions-Peak, in Acetat-Pufferlösung jedoch verschwindet der Lanthan(III)-Peak.
