Area of Science:

  • Interventional Radiology
  • Vascular Imaging
  • Medical Device Technology

Background:

  • Partial splenic embolization is used to treat various conditions.
  • Accurate monitoring of embolization procedures is crucial for patient outcomes.
  • Current methods for monitoring splenic embolization may lack precision.

Purpose of the Study:

  • To evaluate the utility of blood flow measurements in guiding partial splenic embolization.
  • To determine if blood flow changes correlate with the extent of splenic parenchymal reduction.
  • To assess the potential of blood flow analysis as a monitoring tool for embolization procedures.

Main Methods:

  • Utilized time density analysis of contrast medium injections in the splenic artery.
  • Employed digital subtraction angiography (DSA) with modified software for measurements.

  • Performed partial splenic embolization in five patients, guided by blood flow reduction to 50%.

    • Main Results:

    • Blood flow measurements successfully demonstrated changes resulting from embolization.
    • The procedures were guided to achieve a 50% reduction in splenic artery blood flow.
    • Blood flow measurements showed a strong correlation with the achieved splenic parenchymal reduction.

    Conclusions:

    • Blood flow measurements derived from DSA are effective in guiding partial splenic embolization.
    • This method accurately predicts the degree of splenic parenchymal reduction.
    • Blood flow analysis shows significant promise as a real-time monitoring technique for splenic embolization.
