Abstract: Background:  There is limited information on the long-term outcome in liver transplant (LT) subjects undergoing partial splenic embolization (PSE) prior to full dose pegylated interferon/ribavirin (peg-IFN/RBV). Methods:  Retrospective review of eight LT subjects after PSE and antiviral therapy. Results:  Baseline platelets and neutrophils were <50 000 cells/mL and <1000 cells/mL in 75% and 50%. Mean splenic infarction volume was 85 ± 13%. PSE produced major complications in three (37.5%): recurrent sterile netrophilic ascites and renal insufficiency (n = 2), and splenic abscess (n = 1). Full-dose peg-IFN/RBV was started in seven (87.5%), with two early withdrawals (28.6%) despite early virological response (toxicity and infection); both subjects died. Anemia led to RBV dose-adjustment in six (86%), with human recombinant erythropoietin (EPO) use in four (57%). No peg-IFN adjustments or granulocyte-colonies stimulating factor were needed. Two patients reached sustained virological response (SVR) (28.6%). Two non-responders maintained prolonged therapy with biochemical/histological improvement. After a median follow-up of 151 wk, we observed significant improvements in hematological parameters, aspartate aminotransferase, alanine aminotransferase, international normalized ratio, and prothrombin activity. Conclusions:  Extensive PSE after LT produced significant morbidity (37.5%). Peg-IFN/RBV was completed in five out of seven (71%), with SVR in two (28.6%). RBV adjustement due to anemia was high despite EPO use. Only patients able to complete or maintain antiviral therapy survived, with long-term significant benefits in hematological parameters and liver function tests.
