Abstract: Objective To investigate the efficacy of percutaneous microwave ablation in patients with hepatic cavernous hemangioma（HCHs） and to summarize the experience of management of hemoglobinuria. Methods Fifty-four patients with HCHs and 80 lesions were rectuited in our hospital between February 2012 and December 2017,and all patients were treated by ultrasound-guided percutaneous microwave ablation. All patients were followed-up for 6 to 12 months. Postoperative complications,especially the management of hemoglobinuria were presented. Results Out of the 80 lesions from the 54 patients with HCHs,78 disappeared after ablation,and 2 were destroyed largely because of the special occupation;at the end of followed-up,the CT and/or ultrasound showed that all lesions were shrunk,and totally disappeared in 41（75.9%）,shrank greater than 50% in 8（14.8%）,shrank less than 50%,but greater than 25% in 4（7.4%）,shrank less than 25% in 1（1.9%）;on one with post-operational liver or renal function abnormality was found in our series,and 3 to 4 days after the operation,8 patients 14.8%） had hemoglobinuria,and turned to normal two days after symptomatic management;2（3.7%） had ascites,5 had right upper quadrant of abdominal pain,and 7（12.3%） had nausea and vomiting,all subsided after appropriate management. Conclusion Percutaneous microwave ablation is an efficacious,relatively simple and safe in treatment of patients with HCHs. The hemoglobinuria is a common complications after operation because of thermal effect and injuries,which should be taken into consideration after microwave ablation therapy in clinical practice.
