中文摘要 | 自1991年七月開始之四年內,我們總共分析了88位在經動脈門靜脈肝臟電腦斷層檢查中,有肝實質灌流缺損的病人。28位病人(30處病灶)有楔形灌流缺損,其中20處的缺損形狀與肝葉分佈吻合。楔形灌流缺損的主要原因為肝門脈侵犯或栓塞(10處),薄層血流(11處),和動脈門靜脈交流(8處)。9位病人則呈現散在斑駁狀的灌流缺損,其中有7位病人與肝硬化有關。此篇論文在尋求非肝腫塊所引起的灌流缺損及其潛在原因,希望因此幫助了解經動脈門靜脈肝臟電腦斷層中所反應的生理及病理現象,從而降低該項檢查之誤判率。 |
英文摘要 | In order to evaluate the variable features of perfusion defects in liver parenchyma through computed tomographic arterial portography (CTAP), we collected 38 cases from July 1991 to March 1996. Thirty wedge-shaped filling defects were found in twenty-eight cases. Among them, 18 lesions were lobar or segmental. The major causes of the filling defects were portal vein (PV) invasions or thromboses (10), laminar flows (11), and arterioportal (AP) shunts (8). Nine patients had diffuse and mottled filling defects. Seven of them had liver cirrhosis. We correlated the perfusion defects with the underlying causes and hoped to understand more about the pathologic and physiologic process reflected by CTAP. |
