Partial splenic arterial embolization successfully treated hypersplenism in a child, but led to a splenic pseudocyst. This complication was effectively managed with percutaneous drainage, avoiding surgery.

Area of Science:

  • Interventional Radiology
  • Pediatric Gastroenterology
  • Vascular Surgery

Background:

  • Congenital hepatic fibrosis can cause portal hypertension and hypersplenism.
  • Hypersplenism leads to low platelet counts and variceal bleeding.
  • Partial splenic arterial embolization is a treatment option for hypersplenism.

Observation:

  • A 10-year-old boy with congenital hepatic fibrosis and portal hypertension underwent partial splenic arterial embolization for hypersplenism.
  • Following embolization, platelet counts improved and variceal bleeding stopped.
  • One month later, the patient developed vomiting and an abdominal mass, revealing a large splenic cyst.

Findings:

  • Computed tomography confirmed a splenic pseudocyst with minimal residual splenic tissue.

  • Percutaneous drainage yielded 2,800 mL of fluid.
  • The complication was attributed to splenic necrosis and liquefaction post-embolization.

    • Implications:

    • Splenic pseudocyst formation is an unusual complication of splenic arterial embolization.
    • Percutaneous drainage is an effective non-surgical treatment for this complication.
    • This case highlights the importance of monitoring for delayed complications after splenic embolization.
