Summary
Sonography is the preferred imaging method for spleen evaluation after transcatheter embolization for portal hypertension. It effectively identifies splenic infarcts and aids in preventing complications like abscess formation.
Area of Science:
- Interventional Radiology
- Diagnostic Imaging
- Hepatology
Background:
- Portal hypertension management often involves splenic artery embolization.
- Post-embolization splenic evaluation is crucial for monitoring complications.
- Comparing diagnostic modalities for splenic assessment is essential.
Purpose of the Study:
- To compare sulfur colloid scintigraphy and real-time sonography for spleen evaluation after transcatheter splenic artery embolization.
- To determine the optimal imaging technique for follow-up assessment of the spleen in patients with portal hypertension.
Main Methods:
- Retrospective analysis of 11 patients undergoing transcatheter splenic artery embolization.
- Evaluation using sulfur colloid scintigraphy and real-time sonography of the left upper quadrant.
- Comparison of imaging findings, focusing on splenic infarct detection and characterization.
Main Results:
- Both scintigraphy and sonography detected six splenic infarcts.
- Sonography visualized the characteristic wedge shape of infarcts in four of six cases.
- No splenic abscesses were observed in any patient.
Conclusions:
- Real-time sonography is recommended as the primary imaging method for spleen evaluation post-embolization.
- Sonography's ability to characterize infarcts aids in treatment planning and complication avoidance.
- This approach can help prevent splenic abscess formation.
