摘　　要：目的　研究肝癌合并动—静脉瘘 (AVF)在CT增强扫描中的表现及对其诊断价值。方法　 50例肝癌合并AVF患者均先行螺旋CT平扫及增强扫描 ,后经肝动脉造影证实。对比分析CT征象和肝动脉造影所见。结果　 1 7例动—门静脉瘘 (中央型 ) ;1 0例动—门静脉小分支瘘 (周围型 ) ;3例动—肝静脉瘘 ;5例合并上述三种表现 ;2例合并动—门静脉瘘及动—肝静脉瘘 ;另 1 3例无特征性。CT显示AVF征象 37例 ,敏感性 74%。提示AVF诊断 2 6例 (52 % )。结论　门静脉和 /或下腔静脉提前显影 ,尤其相应肝叶、段或亚段性显著强化视为AVF的诊断依据。Objective To study the signs and the value of CT enhanced scanning in diagnosing the liver cancer combined arteriovenous fistulae(AVF).Methods 50 cases of the liver cancer combined AVF had plain and enhanced scanning by spiral CT,then proved by hepatic arteriography.The signs of CT and hepatic arteriography were contrast analyzed.Results CT scan showed 17 cases of artery-portal vein fistulae (centre),10 cases of artery-the small branch of portal vein fistulae(periphery),3 cases of artery-liver vein fistulae,5 cases combined the signs aforementioned,2 cases combined the artery-portal vein fistulae and the artery-liver vein fistulae,and the 13 cases no the characteristic signs of CT,37 cases of the signs of AVF were found by CT,sensitivity 74%.26 cases were diagnosed as AVF,postitive rate 52%.Conclusion The development of portal vein and/or the inferior caval vein ahead in artery phase,especially the parenchyma of the lobes,segments and subsegments of liver,may be a foundation of the diagnosis of AVF.And we discussed the limitation of the CT examination in diagnosing this complication.
