This paper reports on an investigation of the influence on the echosignal from porcine artery walls due to two different formalin fixationprocedures. The lumen diameter, the wall thickness and the mean echogenicitywere calculated. In general, the fixation resulted in a more rigid wall. Whileconventional formalin fixation resulted in shrinking and a slight loss inechogenicity (p < 0.01), fixation of the artery under stretch and pressure didnot.
The results of the study suggest that fixation with pressurized formalinis the preparation method of choice for in vitro investigation of arteries.
