Background and study aimsSplenectomy has been associated with high perioperative morbidity and mortality. Partial splenic artery embolisation (PSE) was found to be an effective and safer method but with numerous complications. Local thermal ablative techniques such as microwave ablation (MWA) have been tried and were found to be safe and effective alternatives. This randomised controlled study aimed to compare the efficacy and safety of MWA versus PSE in the treatment of hypersplenism in patients with post-hepatitis C cirrhosis.Patients and methodsIn total, 40 patients with post-hepatitis C cirrhosis complicated with hypersplenism were randomised into two groups: Group I: 20 patients treated with percutaneous MWA of splenic parenchyma under ultrasound guidance and Group II: 20 patients treated with PSE using Embosphere.ResultsThere was a significant increase in haemoglobin levels in group I compared with group II after 3months of follow-up. However, White blood cell (WBC) count and platelets significantly increased more in group II than in group I after 1month. Postprocedure significant hyperbilirubinaemia, hypoalbuminaemia, decreased prothrombin concentration, and increased creatinine levels were encountered in group II only. There was a significant increase in postoperative complications in group II compared to group I, and a single case of mortality was reported in group II.ConclusionMWA and PSE were comparably effective; however, MWA was safer than PSE, which caused serious adverse events and mortality. MWA appears to be a good alternative for the treatment of hypersplenism in patients with cirrhosis and portal hypertension.
