DE AMORIM JUNIOR, Adelmar Afonso  y  ACCIOLY LINS AMORIM, Marleyne José Afonso. SISTEMATIZATION OF THE CRANIAL Vena cava IN BUFFALOS (Bubalus bubalis bubalis _ SIMPSON, 1945). Rev. chil. anat. [online]. 2002, vol.20, n.3, pp. 295-302. ISSN 0716-9868.  http://dx.doi.org/10.4067/S0716-98682002000300011.

The almost complete lack of knowledge of the anatomical characteristics of this race allows us, here, to study the circulatory system in relation to the veined drainage of the large systemic venous trunks _ the cava system. In the literature many reports can be found on the arterial vascular pattern in several areas of the body in domestic animals as well as in savages; conversely, there is a shortage of pertinent data on the veined vascular pattern. For the present work 25 animals were utilized with the object of dissecting and systemizing the vessels, animals were fetuses with ages of between 5 and 9 months, 15 being females and 10 males. In the cranial vena cava the following origin tributaries were observed: External right and left jugular veins and their collateral tributaries; the internal right and left jugular veins; the mediastinial and pericardial; the internal right and left thoracic; thymic; the right and left subclavian and the right and left costocervicalvertebral venous trunk, and occasionally the thoracic duct.
