目的为壁冠状动脉比较解剖学积累资料,为选择动物模型提供依据。方法家猪心脏塑化染料灌注,10%甲醛溶液固定,大体解剖显示壁冠状动脉,测量数据,并与既往文献报道的犬的壁冠状动脉分析比较。结果家猪壁冠状动脉出现率为50.0%,前室间支、后室间支壁冠状动脉出现率为15.0%、27.5%。前室间支壁冠状动脉近端径(1.96±0.71)mm,远端径(1.52±0.80)mm,长度(9.19±6.58)mm。总壁冠状动脉长度(9.20±4.99)mm。一支血管上可出现1-2处的壁冠状动脉壁。壁冠状动脉可以扭曲和发出细小的分支血管。结论家猪可以作为动物模型研究壁冠状动脉,但犬比家猪更为适合。
The aim is to compare the anatomical data of the wall coronary arteries to provide a basis for the selection of animal models. Methods Pigs were perfused with heart plasticized dye and fixed with 10% formalin. The wall coronary arteries were measured and the data were analyzed. The wall coronary arteries of dogs were compared with the previous reports. Results The prevalence rate of porcine coronary arteries was 50.0%. The incidence of anterior intervertebral branches and posterior interventricular septal coronary arteries was 15.0% and 27.5% respectively. The diameter of the proximal coronary artery in the anterior chamber was (1.96 ± 0.71) mm, the distal diameter was (1.52 ± 0.80) mm and the length was (9.19 ± 6.58) mm. Total wall coronary artery length (9.20 ± 4.99) mm. A vessel can appear on the wall at 1-2 coronary wall. Wall coronary arteries can distort and emit minute branch blood vessels. Conclusion Domestic pigs can be used as an animal model to study the coronary arteries, but dogs are more suitable than domestic pigs.
