中文摘要 | 本篇研究探討40名單純性心室中隔缺損之兒童,於開心手術前一個月內所做之超音波心圖及心導管所測之缺損大小,與開心手術時測量之結果做比較。病人當中,男性27名,女性13名(平均年齡:10個月-9歲)。根據手術中所見分類,屬於膜旁型佔24 名,(月脊)上型14名,心內膜缺損型2名。最大缺損面積以公式1/4πDe^2計算(De為超音波心圖測量之最大缺損直徑)。最大鑲嵌血流面積,由彩色超音波心圖測得且以體表面積校正之。另外,由心導管左心室攝影圖四室面及左外側面所測之最大缺損面積,亦由公式1/4πDa^2計算之。(Da為心導管測量之最大缺損直徑)。將以上三種不同之測量結果,分別以線性回歸分析,我們發現:(1)雙面超音波心圖測量之最大缺損直徑及最大缺損面積,與左心室攝影圖之測量值,存在良好之相關性(r=0.8021及0.7837)。(2)雙面超音波心圖測量之最大缺損面積,與手術中測量值之相關性較左心室攝影圖為高(r=0.9313對0.8036)。(3)雙面超音波心圖測量之最大缺損面積與彩色超音波心圖測量之最大鑲嵌血流面積之相關性,亦較左心室攝影圖為高(r=0.8076對0.6419)。由此可見,藉由最大缺損直徑,最大缺損面積,及校正後之最大鑲嵌血流面積之測量,以超音波心圖評估單純性心室中隔缺損,實為一非侵襲性且十分準確之方法。 |
英文摘要 | Both 2-D echocardiography and angiocardiography were performed preoperatively in 40 children with isolated ventricular septal defect (VSD). The diagnosis of VSD was confirmed and the size of VSD was measured during operation within one month of the study. There were 27 males and 13 females (age: l0mos-9yrs). The VSD was classified into perimenbranous type (24), supracristal type (14), and AV canal type (2) by surgery. The maximal VSD areas were calculated by l/4πD^2(subscript e) (D(subscript e)=maximal defect diameter measured by 2D echo). The maximal shunt flow areas were measured by color Doppler echocardiography from frame by frame search of the video tape. The maximal shunt flow area was corrected by the body surface area to be the maximal shunt flow area index. A left ventriculogram (LVG) was performed from 4-chamber and left lateral views to measure the maximal diameter of the defect. The maximal defect area of VSD on angiocardiogram was also calculated by l/4πD^2(subscript a) (D(subscript a)=maximal defect diameter measured by angiocardiography). The VSD areas measured by different methods were compared by the linear regression analysis. We found that: (1) there is good correlation of the maximal defect diameter and the area of ventricular septal defect by 2-DE and LVG (r=0.80, p<0.0001 v.s. r=0.78, p<0.000l). (2) the ventricular septal defect area by 2-DE had a better correlation with the surgical measurement than that by LVG (r=0.93, p<0.000l, V.5. r=0.80, p<0.000l). (3) the size of ventricular septal defect measured by two-dimentional echocardiography has a better correlation with the MSFAI than the LVG did (r=0.81, p<0.0001, v.s. r=0.64, p<0.0001). Therefore, by measuring the maximal defect diameter, maximal defect area and maximal shunt flow area index, the echocardiography can provide an accurate and non-invasive assessment of isolated VSD in children |
