| Summary: | Background: Partial splenic embolization (PSE) has been proposed in patients with cirrhotic hypersplenism in cases when thrombocytopenia causes clinical manifestations or if there are contraindications to subsequent therapeutic procedures. We provide a retrospective review of the safety and favorable treatment results of 80% splenic embolization in patients with cirrhotic hypersplenism in our institute.
Methods: Thirteen consecutive patients with cirrhotic hypersplenism were included in a 4-year study period. The indications for PSE were as follows: percutaneous treatment of hepatocellular carcinoma (HCC) (n = 3), transarterial chemoembolization plus hepatic arterial infusion chemotherapy for HCC (n = 2), preparation for major surgery (n = 5), and severe purpura (n = 3). PSE was performed with up to 80% reduction of splenic blood flow by radiological intervention. A tight protocol of prophylactic antibiotics was introduced. Patient demographics, procedure-related complication, and efficacy of PSE were analyzed.
Results: The mean follow-up time was 26.1 ± 12.3 months. All the patients tolerated the procedure. The minor complication of postembolization syndromes such as fever and abdominal pain occurred in 38.5% and 61.5% of patients, respectively. Only a major complication of transient ascites needs diuretic therapy occurred in two patients. Pre-PSE platelet count was 35,077 ± 11,049/mm3, and it significantly increased 1 week after PSE, with a mean increase of platelet count to 384% of pre-PSE level (P < 0.001). The effect of PSE sustained to maintain the platelet count significantly at a mean level of 112,636 ± 33,341/mm3, 114,571 ± 30,696/mm3, and 118,000 ± 31,035/mm3 at 12, 24, and 36 months, respectively.
Conclusion: Our series demonstrated that 80% PSE is a safe and effective method to treat patients with cirrhotic hypersplenism. It could not only increase the platelet count within a short period of time but also maintain it at an acceptable level for a long duration. Under a tight protocol of prophylactic antibiotic and delicate technique of PSE, there was no any septic complication developed in our series.
