Abstract

重症病毒型肝炎的診斷,一般依據生化、免疫及病毒檢查,其對病因及疾病程度可視為必須性之檢查,但對其預後則有所不足.傳統之灰階高傳真超音波檢查是個極理想的肝臟影像檢查利器,得以觀察肝內之血管如肝靜脈、門靜脈,其後問世的杜卜勒超音波更增加了機能性的功能得以測量血流之流速及形態,但對肝動脈之檢查仍極困難且耗時.最近發展的彩色杜卜勒超音波更能對肝動脈作即時性的影像,並得以測量血流速度及各項血行力學的指標,因此吾等擬選擇80例病毒肝炎病人在有肝機能失償-黃膽、腹水或肝性腦病變出現時,定期施行彩色杜卜勒超音波檢查,觀察其門靜脈之大小、血流速度、肝動脈之流速、阻力係數、搏動係數等之變化,並以之與病人之病情-存活與否及生償項目之改善與否作一比較.一方面試圖找出彩色杜卜勒超音波檢查在重症病毒肝炎的診斷價值,另一方面嘗試瞭解在肝失償的恢復例及死亡例,其肝臟血流灌注的改變情形,此或許可提供肝衰竭時之病理機轉及肝移植之時機選擇時作更客觀的評估.
