肝转移瘤30例,均经手术和病理证实。原发瘤多为结肠癌、胃癌及胰腺癌。多发性转移瘤26例(87％),单发4例(13％)。动脉造影为多血性,少血性和邻接转移三类表现。(1)多血性转移10例(33.3％),常来源于肉瘤、部分消化道腺癌和鼻咽癌等,造影表现为肝动脉增粗,新生血管丰富且多沿肿瘤周边分布,染色周边部较浓。小部分病例仪表现为瘤结节的均匀染色,缺少其它征象。(2)少血性转移16例(53.3％),主要来源于胃肠癌。造影显示肝动脉分支受压移
30 cases of hepatic metastases were confirmed by surgery and pathology. The primary tumors are colon cancer, gastric cancer and pancreatic cancer. There were 26 cases (87%) of multiple metastatic tumors and 4 cases (13%) of solitary metastases. Arterial angiography is characterized by multiple hemorrhage, less bloody and adjoining transfer. (1) Multiple bloody metastases occurred in 10 cases (33.3%), often from sarcomas, partial digestive tract adenocarcinomas, and nasopharyngeal carcinomas. The angiographic findings were thickening of the hepatic arteries, rich neovascularization, and distribution along the periphery of the tumor, staining of the peripheral area. Thicker. A small number of cases showed uniform staining of tumor nodules and lacked other signs. (2) 16 cases (53.3%) of less bloody metastases, mainly from gastrointestinal cancer. Angiography shows pressure branch of hepatic artery branch
