Splenic artery embolization as an adjunctive procedure for portal hypertension

Splenic embolization is a technique that can be used alone or in conjunction with other treatments for the mitigation of portal hypertension and associated physiological effects of portal hypertension. This technique can be used safely when total embolization volume is ~50% and the procedural and periprocedural time periods are covered with antibiotics. In this patient population, partial splenic embolization can decrease the incidence of variceal bleeding, and protection can persist for at least a year. Additionally, liver function tests and serum cell counts can be expected to improve. Although not frequently used as primary therapy for patients with portal hypertension, splenic embolization can often be helpful as an alternative or adjunctive procedure.

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.

Percutaneous Image-Guided Splenic Procedures: Update on Indications, Technique, Complications, and Outcomes

Percutaneous image-guided splenic procedures are seldom performed due to fear of complications, mainly hemorrhage. Percutaneous splenic invasive procedures are, however, safe, and in most cases, the complication rates are similar to those of other abdominal organs. In most patients, biopsy of a focal splenic lesion establishes the diagnosis. Aspiration and drainage of splenic collections are performed obviating the need for splenectomy. In this review we describe the indications, technique, complications, and outcomes of percutaneous splenic biopsy, aspiration, and drainage.
