【摘要】 目的 研究不同参数数字减影血管造影对肝恶性肿瘤诊断的临床价值。方法 选择经临床诊断的原发性肝癌患者160例,转移性肝癌40例,分别进行肝总动脉常规造影(RA)及肝总动脉长时间低流率造影(LTLRA),对造影图像进行分析评价,对造影表现、检出病灶进行统计学处理。结果 原发性肝癌造影血供表现为:肝总动脉增粗、肝动脉受侵、抱球征、肿瘤血管、肿瘤染色、肝动脉-门静脉瘘、肝动脉-肝静脉瘘等,其中以肿瘤染色和肿瘤血管出现率最高;转移性肝癌主要表现为肿瘤血管、肿瘤染色,不同大小的病灶血供表现各不相同。原发性肝癌的病灶检出,LTLRA组较RA组检出病灶多95个,检出率提高15.10%,2组比较,有显著性差异(P<0.05)。转移性肝癌的病灶检出,LTLRA组较RA组检出病灶多76个,检出率提高33.33%,2组比较,有显著性差异(P<0.05)。结论 和RA比较,LTLRA可明显提高病灶检出率,特别是对于转移性肝癌的病灶。更多还原

【Abstract】 Objective To discuss the value of hepatic artery routine angiography(RA) and long time low rate angiography(LTLRA) in diagnosing liver malignant tumors.Methods 200 cases with liver malignant tumors(160 cases of primary hepato-cellular carcinomas,HCC and 40 cases of hepatic metastatic tumors,HMT) diagnosed by clinic underwent DSA(RA and LTLRA)examinations.DSA images were analyzed,and the data were dealed with statistical method.Results On DSA images,the features of HCC and HMT included dilation of liver artery or its branches,invasion of liver artery,sign of grasping sphere,tumor’s vessels,tumors stain and fistula of liver atery-pportal vein or liver atery-liver vein.95 lesions of HCC(15.10%) and 76 lesions of HMT(33.33%)were detected more by LTLRA than RA,there was a significant difference in the sensitivity of detection between RA and LTLRA(P<0.05).Conclusion In comparison with RA,LTLRA can improve the detecting rate of hepatic lesions,especially for metastatic carcinomas.更多还原
