目的：根据灌注动脉的室间隔，有3种类型的循环优势：右，左和平衡。在这项研究中，供应室间隔的冠状动脉分支进行了研究，在体内的一个大组患者的多探测器计算机断层扫描（MDCT）冠状动脉造影。此外，冠状动脉变异与冠状动脉diseases.Materials和方法：该研究包括325例连续患者（214名男性和108名女性，平均年龄为59 - 14岁）谁接受了MDCT冠状动脉造影。使用16排探测器计算机断层扫描仪进行多探测器计算机断层扫描。结果：本组病例中，右冠状动脉型227例（70%），左冠状动脉型40例（12.5%），平衡型40例（12.5%）。58例（17.5%）。217名男性中有150名（69%）发现右循环占优势，108名女性中有77名（71%）发现左循环占优势，217名男性中有26名（12%）发现左循环占优势，108名女性中有14名（13%）发现左循环占优势; 217名男性中有41名（19%）和108名女性中有17名（16%）发现平衡/共显性循环。然而，在冠状动脉循环类型方面，两性之间没有发现显著差异。68例（20.9%）患者通过MDCT确定了冠状动脉疾病，34例（10.4%）患者还确定了冠状动脉变异。冠状动脉变异的数量和比率均显着较高的患者与左动脉dominance.Conclusions：冠状动脉变异和病理的知识是重要的，在计划的治疗和解释的结果，心血管疾病。我们的研究表明。虽然右优势循环在一般人群中更常见，但冠状动脉疾病和冠状动脉变异在左优势循环的个体中更常见。
Purpose: Depending on the perfusing interventricular Septum of the arteries, there are 3 types of circulation dominance: right, left, and balanced. In this study, coronary artery branches supplying the ventricular septum were investigated in vivo in a large group of patients by multidetector computed tomography (MDCT) coronary angiography. In addition, the association of coronary artery variations with coronary arterial disease was investigated.Materials and Methods: The Study included 325 consecutive patients (214 men and 108 women, with a mean age of 59 14 years) who underwent MDCT coronary angiography. Multidetector computed tomography was performed with a 16-detector-row computed tomographic scanner. The type of dominance, coronary arterial diseases, and coronary artery variations were recorded.Results: In our study, the types of coronary circulation were right, left, and balanced in 227 (70%), 40 (12.5%). and 58 (17.5%) patients, respectively. Dominance of right circulation was detected in 150 of 217 (69%) of men and in 77 of 108 (71%) of women; dominance of left circulation was found in 26 of 217(12%) of men and in 14 of 108 (13%) of women; balanced/codominance circulation was found in 41 of 217 (19%) of men and in 17 of 108 (16%) of women. However, no significant differences were detected between the sexes for the type of coronary circulation. Coronary artery disease was determined in 68 patients (20.9%) by MDCT, and coronary artery variations were also determined in 34 patients (10.4%). Both the number and the rate of coronary artery variations were significantly higher among the patients with left artery dominance.Conclusions: Knowledge of coronary artery variations and pathologies is important in planning the treatment and in interpretation of findings of cardiovascular diseases. Our study indicated that. although right dominance circulation is more common in general population, both the coronary diseases and coronary artery variations are more common in individuals with left dominance circulation.
