Abstract
Summary: This paper describes the histological and scanning electron microscopical examinations of the right colic artery of eight ponies. Lesions all had large thrombi surrounding a larva or larvae, with arterial wall thickening. Endothelial shape change, degeneration and loss were present. Fibrin‐platelet red blood cell aggregates were present on endothelial surfaces as well as on the surface of thrombi. Damage to the intima appeared to produce the conditions for progressive thrombus formation.Résumé: Cet article rapporte les résultats obtenus dans l'étude de l'artère colique droite de sept poneys à l'aide du microscope scanner électronique et du point de vue histologique. Toutes les lésions comportaient de gros thrombus formés autour d'une ou de plusieurs larves et un épaississement de la paroi artérielle. Des modifications de l'endothélium ‐perte, dégénérescence et altérations morphologiques furent constatées. Des agrégats de fibrine, de plaquettes et de globules rouges furent observés sur les surfaces endothéliales et sur la surface des caillots. Les lésions de l'intima favorisèrent la formation des thrombus.Zusammenfassung: Dieser Artikel beschreibt die histologischen und elektronen‐mikroskopischen (Raster) Untersuchungen der rechten Colon‐Arterie von acht Ponys. Die Läsionen wiesen alle grosse Thromben um eine oder mehrere Larven herum auf, begleitet von einer Verdickung der Arterienwand. Veränderungen des Epithelsaussehens, Degeneration und Endothels verlust warens nachzuweisen. Aggregate von Fibrin, Thrombozyten und Erythrozyten fanden sich auf den Endotheloberflächen, sowie auf der Oberfläche der Thromben. Der Schaden an der Intima scheint die Voraussetzungen für die progressive Thrombusbildung zu schaffen.This publication has 17 references indexed in Scilit:
