畸形
Methods The results of echcandiograpy for 23 cases of ruptured aortic sinus aneurysm with anisotrophy were compqred with the findings in operation. 方法回顾分析23例主动脉窦瘤破裂合并畸形的超声心动图特征,比较超声心动图与手术诊断结果。
During the process of the deviation,it considers the effect of non Darcy flow and the anisotrophy of gas layers on the productivity of horizontal wells. 从表皮因子的概念出发,推导出非达西流下水平井裸眼完井表皮因子的解析模型,并用有限元法计算结果验证了所推导模型的正确性。
Results The coincidence of the diagnosis to ruptured aortic sinus aneurysm with anisotrophy by echocandiograph was 86.95%(20/23) and its rate of missed diagnosis was 13.04%(3/23). 结果超声心动图对主动脉窦瘤破裂合并畸形诊断符合率为86.
Objective To enhangce the positive rate of diagnosis of ruptured aortic sinus aneurysm with anisotrophy by echocardiograph and to explore the factors resulted in missed diangnosis. 目的评价超声心动图对主动脉窦瘤破裂合并畸形的诊断价值,探讨漏诊原因,以提高诊断阳性率。
