肝动脉栓塞序贯微波消融治疗肝血管瘤效果观察OA

Objective To investigate the clinical efficacy and safety of transcatheter arterial embolization(TAE)sequential microwave ablation(MWA)for hepatic hemangioma(HH).Methods A retrospective analysis was conducted on the clinical data of 60 patients with HH(diameter ranging from 5.0 to 9.9 cm)treated in Interventional Therapy Center for Oncology,Beijing You'an Hospital,Capital Medical University,from January 2018 to December 2024,involving a total of 65 lesions.All patients received TAE sequential MWA.The occurrence of complications within 24 hours after sequential treatment was recorded.The changes in lesion size(maximum diameter and volume)were evaluated by enhanced CT or MRI 6 months after sequential treatment,and the technical effective rate was calculated(with a volume reduction of≥50%as the standard).Results The technical success rate of TAE sequential MWA was 100%.Six months after sequential treatment,the maximum diameter of HH decreased from 7.0(5.7,8.0)cm to 4.5(3.5,5.4)cm(P<0.001);The volume decreased from 111.5(61.9,182.5)cm3 to 34.6(14.8,61.9)cm3(P<0.001).The technical efficacy rate of TAE sequential MWA was 86.2%(56/65).All patients(7 cases)with preoperative abdominal discomfort experienced symptom relief.Regarding complications,31 patients(51.7%)experienced minor complications within 24 hours after sequential treatment,including abdominal pain(16 cases),transient hemoglobinuria(12 cases),low-grade fever(1 case),and minor subcapsular hepatic hemorrhage(2 cases).All complications resolved with symptomatic management,with no severe complications or fatalities occurred.Conclusion TAE sequential MWA for HH may effectively reduce lesion size and alleviate symptoms with good safety,which representing a minimally invasive and reliable treatment strategy.
