Splenic artery embolization prior to splenectomy in end-stage polycythemia vera.
A patient with polycythemia rubra vera and myeloid metaplasia required splenectomy because of local symptoms attributable to a massively enlarged spleen. Preoperative embolization of the splenic circulation with inert materials was performed to reduce splenic size and vascularity in order to permit safe splenectomy. This case illustrates the utility of preoperative splenic embolization when routine splenectomy is contraindicated for technical reasons. The hazards of this technique and guidelines for its clinical use are outlined.
