摘要
目的研究冠状窦显微解剖结构,为临床逆行灌注等技术提供解剖学依据。方法24例10%甲醛固定的健康成人心脏标本,标本全部动脉系统灌注混有红色染料的乳胶,静脉系统灌注混有蓝色染料的乳胶。结果①冠状窦的中轴与上腔静脉的延长线夹角为锐角、直角和钝角,其中锐角(43°～83°)比例最大,占58.3%。②冠状窦口呈椭圆形,其纵径为15.42～22.53(17.72±1.86)mm,横径为3.92～17.45(8.55±2.91)mm。窦口瓣膜形状有半月形、网状或者条索状,部分冠状窦口不存在瓣膜。结论冠状窦的中轴与上腔静脉的延长线夹角可为临床插管提供解剖学数据,以提高插管逆行灌注技术的成功率。
Objective To investigate the microsurgical anatomy of coronary sinus（CS） and its tributaries. To carry on the quantificatical analysis to the important structure.Provides anatomy basis for the technology of retrograde cardiopleia and to insert ductus of ablation and cardiac arrhythmia of mapping and so on in clinical practice. Methods Is fixed after the anticorrosion, in the blood vessel the red emulsion pours into grown-up corpses sign 24. Results （1） The included angle between central axis of CS and elongation of superior vena cava were acute angle, right angle and blunt angle. The largest percentage was acute angle（43°-83°） among three angle,and account 58.3%. （2）CSO was elliptical,and its mean longitudinal diameter was （17.72±1.86）mm（range from 15.42 to 22.53 mm）,transversediameter was （8.55±2.91）mm （range from 3.92 to 17.45 mm）,and the morphous of CSO valvula was half-moon reticulate and trabs,and partial ones didn＇t exist valvula. Conclusion It was different to the included angle between central axis of CS and elongation of Superior vena caval, and observed and measured this included angle for providing anatomy basis for clinical the technology of insert ductus,and improving technical achievement ratio of retroperfusion. The morphous of CSO valvula was half-moon ,reticulate trabs and so on.To grasp the morphous of valvula for pertinent means been choosen .
