[Suppurating splenic infarction originating from endocarditis].
Three cases of splenic infarction complicated by abscess formation during bacterial endocarditis are reported. In all three cases there were associated clinical abdominal signs and, in one case, there was persistently positive hemocultures. The diagnosis was made by CAT scanning. The three patients underwent splenectomy and one patient also underwent valve replacement the same day. The methods of early diagnosis of splenic complications during endocarditis and the indications of splenectomy are discussed. Ultrasonography and abdominal CAT scanning are the most sensitive diagnostic methods for splenic lesions. As splenic rupture is associated with a high mortality and this complication may occur at any time during infarction complicated by abscess formation, early splenectomy is justified when abdominal clinical signs are elicited associated with a persistent, infectious syndrome with or without positive blood cultures, under appropriate antibiotic therapy. Splenectomy should also be considered if valve replacement is carried out in the same circumstances to avoid infection of the prosthesis.
