采用软Ｘ线摄影技术和硅酮灌注技术，对二乙基亚硝胺诱发的大鼠肝癌模型作碘油肝动脉栓塞后的肿瘤门脉血供进行了研究。结果显示：碘油肝动脉栓塞后，较大肿瘤结节（＞５ｍｍ）的周边部分可见门脉血供存在，而较小肿瘤结节内（＜５ｍｍ），其肿瘤血供呈现部分或完全来自门脉。作者认为，碘油肝动脉栓塞不可能产生完全性的肿瘤双重血供的栓塞；门脉血供的存在可能是碘油肝动脉栓塞后部分肿瘤细胞残存的一个重要原因。因此，在碘油肝动脉栓塞后有必要进行经门静脉途径的介入治疗。
Using soft X-ray photography techniques and silicone perfusion techniques, the portal venous blood supply after hepatic artery embolization with lipiodol was studied in diethylnitrosamine-induced rat hepatoma models. The results showed that after hepatic artery embolization with iodized oil, portal blood supply was seen in the peripheral part of larger tumor nodules (>5 mm), while in the smaller tumor nodules (<5 mm), the tumor blood supply was partially or completely Portal. The authors believe that lipiodol hepatic arterial embolization can not produce a complete tumor dual blood supply embolism; the presence of portal vein blood supply may be an important reason for residual tumor cells after lipiodol hepatic artery embolization. Therefore, interventional treatment via portal vein is necessary after lipiodol hepatic artery embolization.
