  • Title: Embolization of the spleen for treatment of splenomegaly and hypersplenism in patients with portal hypertension.

    Abstract:
    Splenectomy in cases of hypersplenism involves significant risk of serious complications, including infection, hemorrhage, portal systemic thrombosis, and necrosis of the stomach or small bowel. Alternative procedures such as transcatheter embolization have been associated with a high frequency of splenic or subphrenic abscess, preventing clinical use. We used partial splenic embolization under careful antibiotic protection to successfully treat thrombocytopenia in 18 patients, most of whom had hypersplenism and splenomegaly secondary to portal hypertension. Of the 30 embolizations performed, the only serious complications encountered were abscess in two patients (who had almost total infarction) and four cases of splenic vein thrombosis. We investigated the possible effect of splenic embolization on portal venous pressure in three patients and found no pressure change.
