Introduction The brachiocephalic artery (BCA) is the largest branch that arises from the aortic arch, which varies in length. The present study focuses on BCA length and its probable correlation with height and torso length. Methods The BCA length (from the artery's origin to the arcus aortae), the length of the torso, and height were measured in 76 embalmed adult human cadavers of Caucasian (Hellenic) origin. Results A total of 74 arteries were measured (36 females and 38 males). The mean length was found to be 3.82 cm (SD=±0.947, SE=0.110). In male cadavers, the mean BCA length was 3.94 cm (SD=±0.980, SE=0.159) and in females, it was found to be 3.69 cm (SD=±0.905, SE=0.151). No statistically significant difference was found (p=0.248, p>0.05) The mean torso length was 62.27 cm (SD=±4.325, SE=0.496) and the mean height was 155.3 cm (SD=±10.124, SE=1.161). The BCA length was correlated with body height and torso length in both sexes. A statistically significant correlation was found only between BCA length and body height in male cadavers (r=0.267, p=0.021). Conclusion The morphometric characteristics of the BCA are of great importance in a number of surgical procedures, such as stenting and catheterization in cases of aneurysms. One statistically significant correlation was observed in our study, which could be considered an important finding, as it could lead to the plausible assumption that greater height leads to the formation of larger arteries.
引言 头臂动脉（BCA）是发自主动脉弓的最大分支，其长度各异。本研究聚焦于BCA的长度及其与身高和躯干长度的可能关联。方法 对76具源自高加索（希腊）人种的成年防腐人体尸体测量BCA长度（从动脉起点至主动脉弓）、躯干长度和身高。结果 共测量了74条动脉（36名女性和38名男性）。发现平均长度为3.82厘米（标准差=±0.947，标准误=0.110）。在男性尸体中，BCA平均长度为3.94厘米（标准差=±0.980，标准误=0.159），在女性中为3.69厘米（标准差=±0.905，标准误=0.151）。未发现统计学显著差异（p=0.248，p>0.05）。平均躯干长度为62.27厘米（标准差=±4.325，标准误=0.496），平均身高为155.3厘米（标准差=±10.124，标准误=1.161）。BCA长度在两性中均与身高和躯干长度相关。仅在男性尸体中发现BCA长度与身高之间存在统计学显著相关性（r=0.267，p=0.021）。结论 BCA的形态测量特征在许多外科手术中具有重要意义，例如动脉瘤病例中的支架置入和导管插入术。在我们的研究中观察到一种统计学显著相关性，这可被视为一项重要发现，因为它可能导致一个合理的假设，即身高越高会导致形成更大的动脉。
