In this study, the collaterals branches of the aortic arch and its main rami were systematized in 30 New Zealand rabbits (Oryctolagus cuniculus). The arterial system was filled with red latex in the opposite direction to blood flow, and fixed in 20% formaldehyde solution. The collaterals branches of the aortic arch were the brachiocephalic trunk and the left subclavian artery. The brachiocephalic truk emitted the left and the right common carotid arteries, continuing as the right subclavian artery. This emitted, from medial to lateral, the arteries: vertebral, superficial-deep cervical common trunk and costocervical-internal thoracic trunk. Already the left subclavian artery emitted the arteries: vertebral, supreme intercostal, internal thoracic, dorsal scapular and superficial-deep cervical common trunk.
