To further understand spatial relationships of common carotid arteries to adjacent structures through evaluation of computed tomographic angiograms in dogs.
24 pet dogs.
A database was searched for triplanar computed tomographic angiograms that included the heart base caudally and the 5th cervical vertebra cranially, without macroscopic abnormalities. Measurements included brachiocephalic trunk length, common carotid arteries' position relative to the trachea, transverse (axial) thoracic height and width, manubrium length, and length of the 7th cervical vertebra (C7).
Measurements (mean + SD) included brachiocephalic trunk length = 3.65 ± 1.34 cm ( = 24), mean thoracic inlet height = 6.51 ± 2.03 cm ( = 23), mean thoracic inlet width = 4.69 ± 1.35 cm ( = 20), mean manubrium length = 3.52 ± 1.15 cm ( = 22), and mean length of C7 = 1.93 ± 0.46 cm ( = 23).
Some or all measurements were feasible in all dogs. Understanding interindividual variation in spatial relationships is pertinent to differentiating normal from abnormal, for surgical planning, and possibly for elucidating the pathogenesis of certain disorders.
It is possible to obtain these measurements in dogs. This technique could be applied to subgroups of dogs (., breeds) and dogs with cervical or thoracic abnormalities.
通过评估犬的计算机断层血管造影，进一步了解颈总动脉与相邻结构的空间关系。
24只宠物犬。
在数据库中搜索三平面计算机断层血管造影，其范围从尾侧的心底至头侧的第5颈椎，且无宏观异常。测量包括头臂干长度、颈总动脉相对于气管的位置、胸廓横径（轴向）、胸廓高度、胸骨柄长度以及第7颈椎（C7）的长度。
测量值（均值±标准差）包括头臂干长度 = 3.65 ± 1.34 cm（n = 24），胸廓入口平均高度 = 6.51 ± 2.03 cm（n = 23），胸廓入口平均宽度 = 4.69 ± 1.35 cm（n = 20），胸骨柄平均长度 = 3.52 ± 1.15 cm（n = 22），C7平均长度 = 1.93 ± 0.46 cm（n = 23）。
所有犬均可进行部分或全部测量。了解空间关系的个体间差异对于区分正常与异常、手术规划以及可能阐明某些疾病的发病机制具有重要意义。
在犬中获取这些测量值是可行的。该技术可应用于犬的亚组（如品种）以及患有颈部或胸部异常的犬。
