This study introduces a safer, outpatient CT during percutaneous transsplenic portography technique. This method uses a thin needle for improved diagnosis of liver tumors, including small hepatocellular carcinomas.

Area of Science:

  • Radiology
  • Hepatology
  • Medical Imaging

Background:

  • Accurate diagnosis of liver tumors requires detailed information on lesion number, size, location, extent, and vascular relationships.
  • CT during arterial portography (CTAP) is highly sensitive for diagnosing hepatocellular carcinoma, especially small lesions.
  • Conventional splenic portography has limitations due to complications like bleeding.

Purpose of the Study:

  • To evaluate a modified CT during percutaneous transsplenic portography technique.
  • To assess the feasibility of using a thin needle and CT detection for improved safety and outpatient accessibility.

Main Methods:

  • Utilized a 0.6-mm (23-gauge) thin needle for splenic puncture.
  • Employed computed tomography (CT) as the imaging detector.

  • Performed CT during percutaneous transsplenic portography.

    • Main Results:

    • The described technique allows for CT during percutaneous transsplenic portography.
    • This modified approach may enable outpatient procedures.
    • Implies potential for reduced complications compared to conventional methods.

    Conclusions:

    • CT during percutaneous transsplenic portography with a thin needle is a viable diagnostic imaging technique.
    • This method offers a potentially safer alternative for diagnosing liver tumors.
    • Facilitates outpatient diagnosis of hepatocellular carcinoma and other liver lesions.
