经动脉栓塞是一项治疗原发性肝癌的有效办法,但许多病例治疗后肿瘤复发。为了达到肿物完全坏死,作者研究了同时栓塞肝动脉和门静脉的10例原发性肝癌的临床和组织学特点。作法是选择性插管到肝动脉注入混有造影剂的1×1×2mm明胶海绵颗粒进行栓塞,紧接着用15cm长的带有聚乙烯套管的穿刺针,经肝穿刺门静脉并做门静脉的造影,随后把导丝送入门静脉,借此把5F的血管鞘插入门静脉,并将50cm长的5F导管经血管鞘插入门脉分支,注入混有造影剂的1×1×2mm
Transarterial embolization is an effective treatment for primary liver cancer, but in many cases the tumor relapses after treatment. In order to achieve complete tumor necrosis, the authors studied the clinical and histological features of 10 cases of hepatocellular carcinoma embolizing the hepatic artery and portal vein simultaneously. The procedure consists of inserting 1×1×2 mm gelatin sponge particles mixed with contrast agent into the hepatic artery for embolization, followed by a 15 cm-long puncture needle with a polyethylene cannula, through which the portal vein is punctured and the portal vein is After the contrast, the guide wire is then sent to the portal vein to insert the 5F blood vessel sheath into the portal vein, and a 50-cm-long 5F catheter is inserted through the blood vessel sheath into the portal vein and injected with 1×1×2 mm of contrast medium.
