Persistenza della vena cardinale di sinistra nel cane
Descrizione ecografica


Barella G., Faverzani S.


Caudal Vena Cava develops in the first weeks of embryonic life, starting from three pairs of vessels, as a result of partial regressive and anastomotic events. These vascular structures can regress only in part and can anastomose in an unusual way, creating vascular malformations (double vena cava) which remain completely asymptomatic. These abnormal vessels can be found, by accident, during the ultrasound examination of the abdomen. The persistence of the Left Cardinal Vein, reported in both humans and dogs, is one of the possible aberration that may arise during the genesis of the Caudal Vena Cava.
