Partial splenic embolization (PSE) is a non-surgical procedure used to treat hypers-plenism in various clinical settings and thus to avoid the disadvantages of splenectomy. PSE can be employed for the treatment of a variety of diseases including hypersplenism , thrombocytopenia, portal hypertension, splenic arterial aneurysms, etc. PSE can effectively relieve the splenic artery steal syndrome which occurred after liver transplantation, and therefore significantly improve the blood perfusion of the recipient liver. Besides, PSE can also be adopted to reduce the bleeding risk in patients with esophageal and gastric varices caused by portal hypertension. PSE is beneficial to the improvement of peripheral hematologic parameters, which helps the patients successfully undergo the high -dose chemotherapy or interferon therapy. In addition, PSE possesses potential curative effect for thrombocytopenia related diseases such as chronic idiopathic thrombocytopenic purpura. This paper aims to make a comprehensive review of the recent progress in the clinical application of partial splenic embolization.
