目的：随着主动脉根部保留方法在心脏外科中的普及，主动脉根部解剖的重要性日益增加。主动脉根部的外科和解剖学描述并不总是一致的。因此，本研究重点关注主动脉根部解剖的外科方面。方法：测量主动脉三连合间的距离、窦基点与窦管交界处的距离以及窦的高度。还获得了窦管连接处和纤维环的周长。此外，还直接测量了每个鼻窦的体积。最后制作纤维环的垂直和水平组织切片。结果：除倾斜角度外，对所有测量参数进行平均并计算标准偏差（SD）。右窦连合距离为 18.82 mm (SD 1.93 mm)，非冠状窦和左冠状窦连合距离分别为 17.43 (SD 2.06) 和 15.21 (SD 1.88) mm。右冠状窦、非冠状窦和左冠状窦的平均高度分别为 19.45 (SD 1.91)、17.68 (SD 1.77) 和 17.45 (SD 1.39) mm。窦高度之间的差异决定了窦管交界处和主动脉根基部的平均倾斜角为 5.470°。主动脉根基部和窦管连接处的平均周长分别为 69.20 (SD 6.93) 和 65.82 (SD 8.31) mm。右冠状窦、非冠状窦和左冠状窦的平均体积分别为 1.6 (SD 0.34)、1.33 (SD 0.27) 和 1.04 (SD 0.231) ml。根据组织学切片，我们可以说纤维环的组织学边界位于叶间三角形处。结论：根据测量数据，我们可以看出，所有参数都遵循这样的模式：右侧窦结构具有最大尺寸，其次是非冠状窦，最后是左侧冠状窦。主动脉根部和窦管连接处的倾斜角度以及直径差异可能与血流动力学和手术相关（C）2002 国际心血管外科学会。由爱思唯尔科学有限公司出版。保留所有权利。
Objective: Since the aortic root preserving methods are spreading in heart surgery, the importance of aortic root anatomy is increasing. The surgical and anatomical descriptions of the aortic root are not always congruent. Therefore, the present study focuses on the surgical aspects of the aortic root anatomy.Methods: We measured the distances between the three commissures, the distances between the basal point of the sinus and the sinotubular junction and the heights of the sinuses. The circumference of the sinotubular junction and the annuli fibrosi were also obtained. In addition, the volume of every sinus was directly measured. Finally both vertical and horizontal histological sections of annuli fibrosi were made.Results: All measured parameters were averaged and the standard deviation (SD) was calculated, except in the case of the tilt angle. The distance for the right sinus commissures was 18.82 mm (SD 1.93 mm), and that of the non- and left coronary sinus were 17.43 (SD 2.06) and 15.21 (SD 1.88) mm, respectively. The mean height of the right, non- and left coronary sinus were 19.45 (SD 1.91), 17.68 (SD 1.77) and 17.45 (SD 1.39) mm, respectively. These differences between the height of the sinuses determines a mean tilt angle of 5.470 for the sinotubular junction and aortic root base. The mean circumference of the aortic root base and of the sinotubular junction was 69.20 (SD 6.93), and 65.82 (SD 8.31) mm, respectively. Mean volumes of the right, non- and left coronary sinuses were 1.6 (SD 0.34), 1.33 (SD 0.27) and 1.04 (SD 0.231) ml. According to the histological sections we can say that the histological border of the annuli fibrosi is positioned at the interleaflate triangles.Conclusion: According to the measured data we can state that all parameters follow the pattern in which the right sinus structures had the greatest dimensions followed by the non coronary sinus, and finally the left coronary sinus. The tilt angle for aortic root base and sinotubular junction, and the difference in the diameters could be of hemodynamic and of surgical relevance (C) 2002 The International Society for Cardiovascular Surgery.
