Splenic artery embolization

Last revised by Henry Knipe on 3 Oct 2022

Splenic artery embolization is an endovascular technique for treatment of splenic and splenic artery pathology as an alternative to splenic artery ligation or splenectomy. It often results in successfully treating the underlying pathology, while maintaining at least partial splenic function. 

There are a multitude of techniques including:

  • partial or complete embolization

  • proximal or distal embolization

  • coil, particle or glue embolization

In contrast to patients who undergo splenectomy, patients who undergo splenic artery embolization are demonstrated to have preserved immune function at long term follow up. This evidence is supported by research that reports the lack of circulating Howell-Jolly bodies on follow up (nuclear remnants in RBCs that occur in asplenic patients).
