Abstract

The study examined variations in morphology and morphometry of the brachiocephalic artery and their clinical implications in dissected cadavers. Fifty-eight (58) adult cadavers, 57 males and 1 female were dissected to expose the brachiocephalic artery, and the morphological and morphometric variations were recorded.Fifty-one (51) cadavers (88%) had the BCA arising directly from the aortic arch while 7 cadavers (12%) had it originating from the common trunk with the left common carotid artery. The BCA arose on the left anterolateral to the trachea in 57 cadavers (98.3%) and one cadaver (1.7%) had it arising in the midline anterior to the trachea crossed the trachea from left to right terminating posterior to the right sternoclavicular joint where it bifurcated into the right subclavian and right common carotid artery in all cadavers. The mean lengths of the torsos and Brachiocephalic arteries were 45.78±2.93cm and 4.14±0.58cm respectively and the two parameters had statistically significant positive correlation (r=0.33, p<0.05).: A majority of the Ugandan cadaveric population have brachiocephalic arteries with the normal origin, course, and branching patterns. The occurrence of origin variants of BCA from the common trunk and anterior midline to the trachea may be associated with tracheal compression and aortic dilation; hence should be considered as a potential risk factor for thoracic aortic aneurysm and during tracheostomy respectively.
肱动脉的解剖变异及其临床意义:乌干达人口尸体研究
该研究探讨了解剖尸体中肱动脉形态和形态计量的变化及其临床意义。解剖了 58 具成年尸体,其中 57 具为男性,1 具为女性,以暴露肱脑动脉,并记录了形态和形态计量的变化。51 具尸体(88%)的肱脑动脉直接起源于主动脉弓,7 具尸体(12%)的肱脑动脉起源于与左侧颈总动脉的共同主干。57具尸体(98.3%)的BCA起源于气管的左前外侧,1具尸体(1.7%)的BCA起源于气管前方的中线,从左到右穿过气管,在右胸锁关节后方终止,在所有尸体中,BCA在此处分叉为右锁骨下动脉和右颈总动脉。躯干和肱动脉的平均长度分别为(45.78±2.93)厘米和(4.14±0.58)厘米,这两个参数在统计学上具有显著的正相关性(r=0.33,p<0.05):大多数乌干达尸体中的肱动脉具有正常的起源、走向和分支模式。肱动脉从总干和气管前中线的起源变异可能与气管受压和主动脉扩张有关,因此应分别视为胸主动脉瘤和气管切开术的潜在风险因素。
