摘要
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 。
Objective To study the characteristics of the blood supply of hepatic metastases, and their value in differentiating with primary liver carcinoma, to discuss the relationship of the metastases to the original tumors.Materials and Methods DSA was performed in 51 cases of hepatic metastasis from a variety of primary tumors. According to the tumor vasculature, the metastases were divided into three types: hypervascular (n=12), moderate vascular (n=7) and hypovascular (n=32). The pathologic histology of the primary tumors included adenocarcinoma (n=38), squamous carcinoma (n=8) and other neoplasms (n=5).Results The blood supply of hepatic metastases was mainly from hepatic arteries and partly from portal veins. 27 cases of hypovascular metastases involved the right lobe of the liver. Single or multiple ring stain on late arterial phase was seen in metastatic adenocarcinomas, while no specific features were found in squamous metastases.Conclusion The location and DSA signs of the lesion are useful discriminating features in the differential diagnosis of primary liver carcinomas and metastases. Some features of the metastases seem to have certain relationship to the original tumors.
