|Imaging Findings, Diagnostic and Treatment Options of Post-transplant Non-occlusive Hepatic Artery Hypoperfusion (Splenic Steal) Syndrome|
- Splenic steal syndrome is an uncommon, probably under-recognized vascular complication after liver transplant.
- Clinical suspicion is raised in case of liver enzyme elevation, altered arterial resistive index detected on post-transplant follow up Doppler ultrasound with patent hepatic artery and portal permeability in the absence of other clinical or histopathological cause of graft failure.
- In such cases, prompt diagnostic/therapeutic arteriography should be performed of the celiac axis. Findings of delayed hepatic arteriogram, large splenic artery diameter, decreased HA/SA diameter ratio, splenomegaly could support diagnostic suspicion
- Transcatheter embolization of the proximal SA is an effective treatment of SSS with low complication rate. If not feasible, surgical banding or ligation of the SA can be an alternative
