Yetişkin bir sığırda foramen ovale

Bu çalışmada, hipertrofi gözlenen yetişkin bir sığır kalbinde, kongenital bir defekt olan kalıcı foramen ovale olgusu tanımlandı. Uygun şekilde diseksiyonu yapılan kalp, basis cordis bölgesinden açılarak defektin yeri ve pozisyonu saptandı. Digital kumpas ile morfometrik ölçümler yapıldı. Daha sonra lezyonlu bölgeden alınan örnekler rutin doku takibinden geçirilerek hematoksilen-eozin (HE) ve Masson’s Trichrom ile boyandı. Atrium dextrum ile atrium sinistrum arasında bulunan defektin, tubüler bir kanal şeklinde olduğu gözlendi. Defekt çevresinde fibroblast, fibrosit ve yoğun kollagen ipliklerinden oluşan geniş fibröz bir dokuya rastlandı. Yapılan inceleme ile defektin makroskobik ve histopatolojik özellikleri ayrıntılı olarak belirlendi.

Foramen ovale in an adult cattle

In this case presentation, patent foramen ovale which is congenital heart defect was described in the hypertrophic heart of an adult cattle. The heart was dissected carefully from the basis cordis area and place and position of defect was determined. Measurements were obtained by the use of a digital caliber meter. Then, tissue samples taken from the defective area stained with haematoxylin-eosin (HE) and Masson's Trichrom staining methods. The defect was in a form a tubuler type channel which was present between atrium dextrum and atrium sinistrum. Around the defect, there was a widespread fibrous tissue composed of fibroblasts, fibrocytes and dence collagenous type fibers. With this case reports, macroscopical and histopathological peculiarities of defect were determined in detail.
