Arterialization strategies not effective: Several of these studies (15), (16), (18) tested the effectiveness of strategies aimed at arterializing capillary blood.
Studies of adult patients: The fingertip or, more commonly, the lower tip of the earlobe are the usual sites of capillary-blood sampling in adults, and the most common method of arterialization is application of a vasodilating cream (e.g., Algipan) to the puncture site five to 10 minutes prior to blood sampling.
Percutaneous in-situ coronary venous arterialization
(PICVA) involves the use of catheters to transform a segment of the coronary venous system into an arterial conduit.
Sensors, commonly used for infants and neonates, are heated to assure arterialization
A lower extremity venous Doppler examination demonstrated arterialization
of the venous system from a fistulous connection (Figure 1).
, the process of vein wall thickening and increasing vein diameter, is dependent on the pressure of the arterial inflow and resistance in the vein (Beathard, 1998).
of the liver causes baro-injury in cirrhosis and focal nodular hyperplasia (FNH).
Focused ultrasound of the vascular malformation may be limited depending size of the lesion, but Doppler interrogation may show high inflow velocity of the feeding artery and/or arterialization
of draining veins.
There is less potential for vein collapse (sucking) due to spasm or insufficient flow, and the increased local volume and pressure may enhance the "arterialization
" of the vessel.
These are almost exclusively diagnosed on color Doppler imaging with the presence of aliasing color flow, high velocity, low-resistance arterial spectral waveforms, and arterialization
of the venous waveform, which persists even on high Doppler scale settings (Figure 14).
(7) Doppler ultrasound (US) may show a characteristic enlarged vascular space with, in the case of an arteriovenous fistula, decreased resistance of the arterial waveform, and arterialization
of the venous waveform.
