With the use of extensive images,
this poster will review the use of pulmonary RFA,
practical technique and useful tips,
follow-up imaging appearances and complications.
Radiofrequency ablation is an image guided,
minimally invasive technique used to destroy tumour tissue.
Current is passed from an electrode through the patient’s tissues and is grounded via skin pads.
Ionic agitation in the tissues adjacent to the needle tip produces heating.
Cell death occurs if heating of over 50 degrees is achieved for 5 minutes. Current applications include local treatment of lung,
renal and bone tumours.
There is growing evidence of its efficacy and in recent...
Findings and procedure details
Tip 1: Staffing Dedicated team of nurses and radiographers familiar with the procedure. Prospective data base of patients. Tip 2: Careful patient selection True oligometastatic disease (<3 lesions per organ fare better than those with more lesions). Lesions less than 4 cm in diameter have a better outcome. Period of at leat 12 months between primary diagnosis and presentation of metastases. PET prior to RFA is very useful to exclude more widespread disease. Tip 3: Use Conscious sedation...
RFA is generally a safe procedure.
There is a steep learning curve in both performing ablation and assessing follow up imaging.
This poster shares our experience of performing over 200 lung ablation procedures.
