Core Tip

Core tip: Inability to ensure the curability of the thrombectomy has been a main obstacle to improving postoperative prognosis of hepatocellular carcinoma with portal vein tumor thrombus, especially for cases with invasion in the main trunk of the portal vein. In this report, we firstly applied the cystoscope as an intravascular endoscope to investigate the cavity of the portal vein after primary tumor removal. The cystoscope offered a clear view of the portal vein cavity from the main trunk to the secondary branch, indicating its suitability as a substitute with a proper size and function to check the portal vein system.
