Partial splenic embolization in the treatment of patients with portal hypertension: A review of the English language literature

This article reviews the existing literature on the use of partial splenic embolization in patients with portal hypertension. All articles published in the English language on splenic embolization or partial splenic embolization as a treatment for portal hypertension were identified with a PubMed search from 1973 through 2005. Partial splenic embolization appears to be efficacious in reducing episodes of variceal bleeding, improving hematologic parameters, enhancing hepatic protein synthesis, and reducing the severity of hepatic encephalopathy. Associated morbidity and mortality appear to be acceptable. The literature, however, is limited in quality. Given the potential benefits of partial splenic embolization, further investigation is warranted to allow evidence-based evaluation of its use.
