A modified CO2 splenoportography technique using ultrafine needles offers a safe and effective way to visualize the portal system for surgical planning when other methods fail.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Vascular Surgery

Background:

  • Traditional splenoportography with 18-gauge needles offered excellent portal imaging but raised bleeding concerns.
  • Arterial portography and noninvasive techniques replaced splenoportography but lack consistent accuracy.
  • Previous imaging studies were inconclusive in a cohort of patients requiring improved diagnostic methods.

Purpose of the Study:

  • To evaluate a modified splenoportography technique using carbon dioxide (CO2) and an ultrafine needle.
  • To assess the safety and efficacy of this modified approach in patients with inconclusive prior imaging.
  • To determine the utility of CO2 splenoportography for surgical planning of the portal system.

Main Methods:

  • A modified splenoportography technique was employed in eight patients.

  • The procedure utilized carbon dioxide (CO2) as the contrast agent.
  • An ultrafine needle was used for splenic access to minimize bleeding risk.

    • Main Results:

    • The CO2 splenoportography procedure was successfully performed in all eight patients.
    • The technique provided adequate visualization of the portal system.
    • No significant bleeding complications were reported.

    Conclusions:

    • CO2 splenoportography is a safe and expedient imaging modality.
    • This technique provides adequate visualization of the portal system for surgical planning.
    • It is a valuable option for selected patients with inconclusive prior imaging studies.
