目的 探讨肝转移瘤血供特点与原发性肝癌的鉴别以及和原发肿瘤的相关性。材料与方法 搜集 5 1例肝转移瘤DSA影像 ,根据肿瘤血管的多少和肿瘤染色深浅分为多血供、中血供和少血供。原发肿瘤包括腺癌 38例 ,鳞癌 8例 ,其他类型 5例。结果 肝转移瘤血供来源主要为肝动脉 ,门静脉参与供血。多血供肝转移 12例 ,中血供 7例 ,少血供 32例。累及肝右叶少血供转移2 7例 ;腺癌转移多于动脉晚期及以后显示多或单发环状染色 ;鳞癌转移不具特征性。结论 肝转移瘤可于发生部位及DSA表现与原发性肝癌鉴别 ,肝转移瘤的某些特征性提示与原发肿瘤有相关性
Objective To investigate the characteristics of hepatic metastasis blood supply and the differentiation of primary liver cancer and its correlation with primary tumors. Materials and Methods 51 cases of DSA images of hepatic metastases were collected. According to the number of tumor blood vessels and the depth of tumor staining, blood supply, blood supply, and blood supply were divided. The primary tumors included 38 cases of adenocarcinoma, 8 cases of squamous cell carcinoma, and 5 cases of other types. Results The source of hepatic metastasis was mainly hepatic artery, and portal vein was involved in blood supply. More blood donor liver metastases occurred in 12 cases, blood supply in 7 cases, and less blood supply in 32 cases. Involved in the right hepatic lobe with less blood for metastasis in 27 cases; adenocarcinoma metastasis more than late and later showed more or single ring staining; squamous cell metastasis is not characteristic. Conclusion Hepatic metastases can be identified in the site of occurrence and DSA with primary liver cancer. Some characteristic features of liver metastases suggest a correlation with primary tumors.
