“…The liver is an ideal organ for ultrasonographic imaging because of its location and tissue consistency. The usefulness of the technique for diagnosis of various liver abnormalities including abscesses in small animals has been well documented (Wrigly, 1985). Ultrasonography is a useful technique for monitoring the onset and progression of experimentally induced abscesses when the site of injection is known.…”

Liver abscesses in slaughtered beef cattle result from aggressive grain-feeding programs. The incidence, averaging from 12 to 32% in most feedlots, is influenced by a number of dietary and management factors. Liver abscesses represent a major economic liability to producers, packers, and ultimately consumers. Besides liver condemnation, economic impacts include reduced feed intake, reduced weight gain, decreased feed efficiency, and decreased carcass yield. Fusobacterium necrophorum, a member of the ruminal anaerobic bacterial flora, is the primary etiologic agent. Actinomyces pyogenes is the second most frequently isolated pathogen. Ruminal lesions resulting from acidosis generally are accepted as the predisposing factors for liver abscesses. F. necrophorum possesses or produces a number of virulence factors that participate in the penetration and colonization of the ruminal epithelium and subsequent entry and establishment of infection in the liver. However, only a few virulence factors have been characterized well. Control of liver abscesses in feedlot cattle generally has depended on the use of antimicrobial compounds. Five antibiotics (i.e., bacitracin methylene disalicylate, chlortetracycline, oxytetracycline, tylosin, and virginiamycin) are approved for prevention of liver abscesses in feedlot cattle. Tylosin is the most effective and the most commonly used feed additive. Tylosin feeding reduces abscess incidence by 40 to 70%. The mode of action of antibiotics in preventing liver abscesses is believed to be via inhibition of ruminal F. necrophorum. Protective immunity against F. necrophorum induced by a variety of antigenic components has ranged from ineffectual to significant protection.

“…La veno-portografía mesentérica directa es un método invasivo que requiere intervención quirúrgica a cielo abierto, incrementando riesgos para el paciente, restringiendo su realización a centros de alta complejidad. La esplenoportografía es una alternativa a cielo cerrado, realizable con guía ecográfica, no exenta de riesgos como hematomas o ruptura capsular esplénica (Wrigley, 1985).…”

Vasculatura Portal Intrahepática: Descripción Anatómica, Radiológica y Ecográfica

et al. 2014

RESUMEN: El presente trabajo describe la arborización del sistema venoso portal intrahepático desde los enfoques anatómico, radiológico y ecográfico. Se realizaron 5 preparados anatómicos mediante inyección de resinas plásticas y posterior corrosión. Por radiología se contrastó el árbol portal en una pieza anatómica. Se realizaron estudios ecográficos bidimensionales y Doppler en 13 caninos de raza Beagle. Estos procedimientos permitieron a los autores comparar la tridimensionalidad de los preparados anatómicos con la bidimensionalidad de los estudios por imágenes.

“…There are no significant conventional ultrasound characteristics to accurately differentiate benign from malignant etiologies. 42,43,46,52,89,94,110,[149][150][151] But most diffuse lymphoma cases exhibit normal echogenicity or are more echogenic than expected. 50,[130][131][132][133][134] Most benign hepatic nodules are isoechoic to the liver during the arterial phase, and maintain isoechogenicity during the portal venous phase at peak contrast enhancement.…”
