| This study was aimed at determining the morphology of the aortic arch in the sparrowhawk. For this purpose, arteries near the heart of six sparrowhawks were assessed. Latex injection method was applied to the three materials and barium sulphate solution was injected into the aorta for angiography in three other materials. It was observed that two major arteries arose from aortic arch in the sparrowhawk: the left brachiocephalic trunk and the right brachiocephalic trunk. These trunks were contiguous arteries but separately originated from the aorta. The brachiocephalic trunks were divided into the common carotid and subclavian arteries after their origins. First, the common carotid arteries are given off by the brachiocephalic trunks. The common carotid... |

| Anomalies arising in the embryological development of the aortic arch and its branches are essencial in the emergence of variations in the origin and course of supra aortic vessels. Classically, 95% of cases, the aortic arch gives rise to the brachiocephalic artery, left common carotid artery and left subclavian artery. While the left vertebral artery arises normally from the left subclavian artery. In this presentation we describe two cases of the left vertebral artery being born of the aortic arch. The importance of anatomical knowledge of this arterial variety is fundamental for base neck and aortic arch surgery, in cervicothoracic trauma that compromises the vascular elements and in endovascular procedures in the region. |

| The aortic arch branches variations have called the attention of several authors, who have handled studies and classifications, both human and in different animals. The common trunk, which is between the brachiocephalic trunk and the common left carotid artery, is the most common variation. We conducted a descriptive and randomized study of the presence of the trunk mentioned before, trying to establish the possible relationship between this variation and the distribution plates of atheroma. The lumen observation makes it possible to define and check the distribution of the ostium, among the common ostium and the ones with common trunks. Regarding the plates of atheroma, it was found that there is a slight prevalence in common trunks cases, with respect to... |
