Summary
Partial splenic embolization (PSE) offers a safe alternative to splenectomy for massive splenomegaly and hypersplenism. This minimally invasive procedure effectively improved hematologic parameters in most patients, with persistent benefits observed long-term.
Area of Science:
- Interventional Radiology
- Hepatology
- Pediatric Hematology
Background:
- Splenectomy for massive splenomegaly and hypersplenism is associated with significant risks.
- Partial splenic embolization (PSE) presents a viable alternative to surgical intervention.
Purpose of the Study:
- To evaluate the efficacy and safety of PSE as an alternative to splenectomy.
- To assess the impact of PSE on hematologic parameters in patients with splenomegaly and hypersplenism.
Main Methods:
- Ten PSE procedures were performed on nine patients (age 8 months to 32 years).
- Procedures utilized a percutaneous femoral artery approach to deliver Ivalon sponge particles into the splenic artery.
- Splenic infarction was confirmed via postembolization angiography.
Main Results:
- No mortality was observed; morbidity was minimal.
- Significant improvements in leukocyte and platelet counts were noted post-embolization.
- Persistent hematologic improvement was observed in seven of eight initially responsive patients over 4 months to 7 years.
Conclusions:
- Partial splenic embolization is an effective and safe alternative to splenectomy for managing massive splenomegaly and hypersplenism.
- PSE leads to significant hematologic improvements with durable outcomes in most patients.
