中文摘要 | 共計14名健康志願者接受肝臟之空腹及飯後彩色杜卜勒超音波檢查以建立國人之肝動脈、門靜脈相關正常值及其飯後之反應。門靜脈不論空腹或飯後皆得以順利檢查之,其空腹之直徑,流速與流量分別為1.17±0.22公分,16.29±.3.68公分/秒及18.7±11.8毫升/秒,這些數值在飯後皆明顯上升且統計學上且有意義,分別為1.38±0.25, 22.72±4.88及33.91±些數值在飯後皆明顯上升且統計學上具有意義,分別為1.38±0.25, 22.72±4.88及33.91±12.63。空腹時1名(7.1%)肝動脈無法檢出,另有5名(35.7%)於飯後無法檢出,其失敗之原因可能與志願者體重有關。飯前之肝動脈最高收縮流速,平均流速及最高舒張流速分別為47.44±14.49, 28.81±10.1,及18.36±6.85公分/秒,這些數據在飯後並無統計學上有意義的差別,但博動指數由1.12±0.36上升至1.58+0.85. (p<0.05),阻力指數由0.61±0.07?徐為0.71±0.08 (p=0.06)。此結果顯示肝動脈之檢查並非全數可達成,尤其高體動者較難,進食對門靜脈之影響遠大於肝動脈。此正常國人肝臟彩色超音?正常直,提供吾人進一步檢查肝疾病時以供正確評估。 |
英文摘要 | To evaluate the response of hepatic vessels, the hepatic artery and portal vein were measured before and after a meal by color Doppler ultrasonography in 14 normal Chinese adults. Portal vein can be identified in all instance with diameter, velocity and flow volume in fasting as 1.17±0.22 cm, 16.29±3.68 cm/sec and 18.7±11.8 ml/sec respectively. These parameters are significantly increased to 1.38±0.25, 22.72±4.88 and 33.91±12.63 respectively (all with p<0.01) after the meal. Successful visualization of hepatic artery was achieved in except one (7.1%) in fasting, but only in 8 out of 14 after the meal. In fasting, hepatic artery peak systolic, mean and peak diastolic flow were 47.44±14.49, 28.81±10.10 and 18.36±6.85 cm/sec. respectively. These values did not alter significantly after the meal. In contrast, pulsatility index increased from 1.12±0.36 to 1.58±0.55 (p<0.05), and resistance index rose from 0.61±0.07 to 0.71±0.08 (p=0.06). The results suggest that the hepatic artery examination is not always successful, especially in heavier-build person and after meal. Compared with hepaticd artery, hemodynamics of portal vein is more easily affected by meal. |
