Intraoperative Contrast-Enhanced Sonographic Portography Combined With Indigo Carmine Dye Injection for Anatomic Liver Resection in Hepatocellular Carcinoma A New Technique

초록

We present a method of intraoperative contrast-enhanced sonographic portography combined with indigo carmine dye injection for anatomic liver resection in hepato cellular carcinoma. During surgery, before dye infusion into the feeding portal vein, the targeted portal vein branch was directly punctured, and a microbubble contrast agent was administered under sonographic guidance. Simultaneous enhancement of the resected hepatic parenchyma with a microbubble contrast agent and blue dye improved estimation of the segmental border in the cutting plane and the tumor resection margin during liver surgery.
