3.1. Pathological findings
The main gross finding was dark reddish coloration in the lungs,
draining a marked amount of serosanguineous fluid. Microscopically,
hemodynamic disturbances were observed in the lungs, highlighting a
marked congestion of blood vessels and alveolar capillaries, and mild
acute alveolar hemorrhage (Figure 1a). In liver, moderate congestion in
zone I and II was detected (Figure 1b). Finally, in kidney,
corticomedullar congestion was also observed. Histopathological
alterations were not perceived in the remaining organs/tissues analyzed.
