OBJECTIVE.本研究旨在评价肝叶萎缩、胆管梗阻和门静脉梗阻之间的关系。材料与方法：对1992年8月至1995年3月间30例肝叶萎缩经动脉门脉造影CT证实的病例进行回顾性分析。评价血管通畅性和胆管梗阻情况。30例患者中有28例被诊断为恶性。22例患者（73%）左叶萎缩，8例患者（27%）右叶萎缩。26例（87%）门静脉阻塞为单侧，局限于萎缩叶。相反，23名患者（77%）的胆管梗阻是双侧的，只有4名患者（13%）的胆管梗阻是孤立于萎缩叶的。萎缩与门静脉阻塞的相关性显著，敏感性为90%，特异性为97%，阳性预测值为96%（p
OBJECTIVE. This study was performed to evaluate the association between hepatic lobar atrophy, bile duct obstruction, and portal vein obstruction.MATERIALS AND METHODS, Thirty cases of hepatic lobar atrophy identified on angiography with CT during arterial portography from August 1992 to March 1995 were retrospectively reviewed by two independent observers. Cases were evaluated for vascular patency and bile duct obstruction. Malignant diagnoses were present in 28 of 30 patients.RESULTS. Twenty-two patients (73%) had atrophy in the left lobe and eight patients (27%) had right lobar atrophy. Portal vein obstruction was unilateral and confined to the atrophic lobe in 26 patients (87%). In contrast, bile duct obstruction was bilateral in 23 patients (77%) and in only four patients (13%) was it isolated to the atrophic lobe. The correlation between atrophy and portal vein obstruction was significant, with 90% sensitivity, 97% specificity, and 96% positive predictive value (p
