Percutaneous bone lesion ablation

摘要: Benign tumors and metastatic bone lesions can be treated by ablation techniques performed either alone or in combination with other percutaneous techniques. Ablation include ethanol acetic acid injection thermal means of energy deposition [including laser, radiofrequency, microwave, cryoablation, radiofrequency ionization magnetic resonance (MR)-guided high-intensity focused ultrasound (HIFU)]. Goal definition the therapy is crucial: proposed as curative treatments benign oligometastatic disease (<3 lesions). Alternatively, these palliative aiming at reduction pain, local control tumor decompression. Depending on lesion’s location combined cementation without further metallic augmentation; enhanced combining transarterial bland embolization chemoembolization. Thermal soft tissues characterized high success relatively low rates potential complications, mainly iatrogenic damage surrounding sensitive structures. Successful requires a sufficient volume protection vulnerable This article will describe general principles governing mechanism action for each technique addition review literature about safety effectiveness imaging-guided malignant (primary metastatic) lesions.
