【摘要】：目的对肝动脉及门静脉肝转移瘤的分布及血供特点进行比较。方法按既定标准对转移瘤患者60例的CT平扫及标准双期增强扫描进行回顾性分析,包括结肠癌及肺癌肝转移患者各30例。根据Couinaud肝段划分法和对肝脏最大瘤灶定位,采用肝动脉增强分数(AEF)评价肿瘤血供,对两组间瘤灶分布、正常肝组织及瘤灶AEF进行比较,对瘤灶直径与AEF进行相关性分析。结果经门静脉肝转移瘤主要分布在肝右叶,占70.0%(21/30);经肝动脉转移瘤73.3%分布在肝左叶(22/30),两组间瘤灶分布具有统计学差异(P=0.00)。肝动脉途径转移瘤AEF(0.68)高于门静脉途径转移瘤(0.52),差异有统计学意义(P=0.01)。两组转移瘤病灶直径变化与AEF变化之间无相关性(r=0.10、0.21)。结论不同路径肝转移瘤的分布和血供均存在一定差异,有助于为肝转移瘤寻找原发肿瘤抑或是原发肿瘤查找肝转移瘤提供一定的指向性。
[Abstract]:Objective to compare the distribution and blood supply of hepatic artery and portal vein hepatic metastases. According to the method of Couinaud segment division and localization of the largest hepatic tumor, the blood supply of tumor was evaluated by hepatic artery enhancement fraction (Couinaud), and the distribution of tumor focus, normal liver tissue and AEF of tumor focus were compared between the two groups, including 30 cases of colon cancer and 30 cases of liver metastasis from lung cancer. The correlation between the diameter of tumor focus and AEF was analyzed. Results Transportal hepatic metastases were mainly located in the right lobe of liver. 73.3% of metastatic tumors were distributed in the liver of Zuo Ye 22 / 30, the distribution of tumor foci was statistically different between the two groups. The distribution of hepatic artery metastasis was 0.68) higher than that of portal vein metastasis (0.52%), and the difference was statistically significant between the two groups (P < 0.01), and the diameter of metastatic tumors in the two groups was significantly higher than that in the portal vein approach (P < 0.05), and there was a significant difference in the diameter of metastatic tumors between the two groups. There was no correlation between the changes of AEF and the changes of AEF. Conclusion the distribution and blood supply of hepatic metastases in different pathways are different. It is helpful to search for primary tumor or primary tumor to find liver metastases.
