Splenic infarction and spontaneous rupture of the spleen after therapeutic embolization.

Abstract

Patients with major hematologic disorders who have hypersplenism and alterations in their immune mechanism are subject to a higher incidence of bacteremia after embolization procedures. In certain instances, these infectious complications can be fatal. Medical splenectomy for hematologic disorders is sometimes complicated by massive splenic infarction and spontaneous rupture; spontaneous rupture appears to be a function of both infarct size and underlying infectious complications. Prophylactic measures can be employed to avoid these complications after interventional splenic embolization.
