作者报告1977年7月~1980年2月 Mount Sinai医院作了150例经肝胆管造影术(THC)。发现16例(9%)有不完全性(11例)或完全性(5例)梗阻,而无肝内肥管扩张,其中5例有总胆管扩张。梗阻部位在肝门(6例)及总胆管行程各部位(9例)。肝内胆管不扩张的最常见病因是:肝门转移性病变4例,良性狭窄4例,结石3例。对梗阻而无肝内胆管扩张这种矛盾现象有下述解释:①根据 Laplace 定律,在恒定的压力作用下,圆柱体内的张力与其直径成正比。假定胆管系统内的
The authors reported 150 cases of hepatobiliary angiography (THC) at Mount Sinai Hospital between July 1977 and February 1980. It was found that 16 (9%) had incomplete (11 cases) or complete (5 cases) obstructions without intrahepatic vascular dilation, of which 5 cases had total biliary dilation. The obstruction site was in the hepatic (6 cases) and the common bile duct (9 cases). The most common causes of non-dilatation of intrahepatic bile ducts were: hepatic portal metastases in 4 cases, benign stenosis in 4 cases, and stones in 3 cases. The contradiction of obstruction without intrahepatic bile duct dilatation has the following explanation: 1 According to Laplace’s law, under constant pressure, the tension in a cylinder is directly proportional to its diameter. Assumed within the bile duct system
