Pdf Summary

This document is a study guide related to the pre- and postoperative imaging considerations in liver surgery, specifically aimed at individuals preparing for the SA-CME test (Study Activity-Continuing Medical Education). It highlights key considerations and questions relevant to liver surgeries such as treatment options for hepatocellular carcinoma, contraindications for surgical resection of perihilar cholangiocarcinoma, and common anatomic variations of the portal vein and biliary tree.<br /><br />Key points from the study guide:<br /><br />1. <strong>Hepatocellular Carcinoma Treatment</strong>: It identifies surgical resection as the treatment of choice for patients with hepatocellular carcinoma (HCC) who do not have cirrhosis.<br /><br />2. <strong>Contraindications for Surgical Resection</strong>: An absolute contraindication for the surgical resection of perihilar cholangiocarcinoma includes interaortocaval lymph node involvement.<br /><br />3. <strong>Portal Vein Variations</strong>: The most common anatomical variation of the portal vein is the right posterior branch as the first branch of the portal vein trunk and portal vein trifurcation.<br /><br />4. <strong>Biliary Tree Variations</strong>: Without the accompanying image, it's impossible to determine what variation is depicted, but options include a triple confluence, accessory ducts, and unusual drainage patterns of the right posterior duct.<br /><br />5. <strong>Complications Post Liver Surgery</strong>: The most feared complication after liver surgery is liver failure.<br /><br />To gain credit, participants must complete the corresponding test online at rsna.org. This document serves as a preparatory tool and does not itself provide educational credit upon completion.
