摘　　要：目的探讨超声对2级以上分支门静脉瘤栓（PVTT）的诊断价值。方法423例原发性肝癌伴PVTT按瘤栓侵犯位置分为A、B两组。对左右肝肿瘤侵犯同侧门静脉分支的概率，A、B两组的PVTT声像图特征、搏动性动脉血流检出率、超声造影“快进快退”表现检出率行x2检验。结果瘤栓侵犯肿瘤同侧门静脉分支者占97．3％（329／338）。两组灰阶超声声像图特征、搏动性动脉血流检出率差别有统计学意义（P〈0．01），超声造影结果差别无统计学意义（P〉0．05）。结论超声医师熟悉门静脉瘤栓生长特性，结合超声检查可大大提高2级以上分支门静脉瘤栓的检出率，有重要的临床意义。Objective To probe the diagnostic value of ultrasonography （US） in tumor thrombosis locating in more than 2 grade branches of portal vein. Methods US materials of 423 cases of primary hepatic carcinoma （PHC） with portal vein tumor thrombosis （PVTT） were retrospectively analyzed. All cases were divided into A and B groups. The probability of left and right liver tumor invading homolateral portal vein branches,ultrasonogram charac- teristics and detection rate of pulsatile arterial flow and fast-in and fast-out enhancement pattern of PVTT were compared with ;（2 test. Results Tumor thrombosis invading homolateral portal vein branches was found in 97.3% （329/ 338）cases. The location of tumor thrombosis invading portal vein was mostly in accordance with that of tumor foci （P〈0.01）. ultrasonogram characteristics and detection rate of pulsatile arterial flow of two groups were different with statistical significance （P〈0.01）. The difference of two groups of contrast-enhanced ultrasound weren＇t obviously （P〉0.05）. Conclusions US examiner being familiar with growth characteristics of PVTT and comprehensive use of ultrasound can raise the detection rate of PVTT.
