摘　　要：目的观察山羊肺静脉心肌袖的形态特征,为异位房颤动物模型提供依据。方法对30例山羊肺静脉,充分暴露心肌袖,进行形态学观测。结果30例羊心均出现肺静脉心肌袖,其中斜形47.6%,环形40.9%,纵形11.5%。右上、右下、左下、左上肌袖厚度分别为0.46±0.14 mm、0.35±0.16 mm、0.35±0.11 mm、0.37±0.13 mm;长度分别为10.75±3.15 mm、9.46±2.20 mm、11.41±2.87 mm、9.20±2.88 mm。结论山羊肺静脉心肌袖出现率为100%,4支肺静脉中以右上肺静脉直径最大。Objective To observe the morphologic characteristics of myocardial sleeve in sheep,s pulmonary veins, and to provide a foundation of making the model of ectopic atrial fibrillation. Methods Thirty sheep, s hearts were dissected to show the myocardial sleeve in sheep, s pulmonary vein clearly , and their morphologic structures were observed. Results The myocardial sleeve were found in all sheep,s pulmonary veins, in which diagonal were 47.6% ） ,annular 40.9%, longitudinal 11.5 %. The average thickness of myocardial sleeve in the right upper, the right lower, the left lower and the left upper pulmonary vein were 0.46 ± 0.14 mm,0.35 ± 0.16 mm,0.35 ± 0.11 mm and 0.37 ± 0.13 mm respectively, and its average lengths were 10.75±3.15 mm,9.46±2.20 mm, 11.41 ±2.87 mm and 9.20±2.88 mm respectively. Conclusion The occurrence rate of myocardial sleeve in thirty sheep,s pulmonary vein is 100%. The diameter of the right upper one is maximum in the four pulmonary veins.
