畸形
Methods The results of echcandiograpy for 23 cases of ruptured aortic sinus aneurysm with anisotrophy were compqred with the findings in operation. 方法回顧分析23例主動脈竇瘤破裂合并畸形的超聲心動圖特征,比較超聲心動圖與手術診斷結果。
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. 從表皮因子的概念出發(fā),推導出非達西流下水平井裸眼完井表皮因子的解析模型,并用有限元法計算結果驗證了所推導模型的正確性。
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). 結果超聲心動圖對主動脈竇瘤破裂合并畸形診斷符合率為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. 目的評價超聲心動圖對主動脈竇瘤破裂合并畸形的診斷價值,探討漏診原因,以提高診斷陽性率。
