Suprimento arterial dos lobos torácicos do timo em cães da raça

The origins, numbers and type of arterial branches responsible for the blood supply of thoracic lobes of the thymus were studied in 28 stillborn dogs of the Great Dane, of which 18 were males and 10 were females. The arterial systems of these animals were filled with aqueous solution of Neoprene Latex “450”, 50%. After, the specimens were fixed in 10% formaldehyde aqueous solution. The lobes of the thymus were supplied by direct or indirect arterial branches coming from the right and left internal thoracic arteries, pericardiacophrenicas arteries, right and left costocervicais trunks, and left subclavian artery. The left subclavian artery and brachiocephalic trunk emitted direct branches towards the left thoracic lobe of the thymus.
