- Microwave ablation (MWA)
Microwave ablation (MWA) is the application of electromagnetic waves to treat solid tumors. By causing oscillation of polar water molecules, microwaves produce frictional heating and ultimately induce cellular death via coagulation necrosis. This technique has been largely used to treat liver, kidney, lung, and bone tumors.
Indications
-
liver
pancreas: advanced and non-resectable pancreatic tumors for symptomatic relief (i.e. pain control)
kidney: small renal masses
lung: lung tumors
-
bone
painful metastatic lesions
thyroid: thyroid nodules
Advantages
MWA offers the following advantages over radiofrequency ablation (RFA):
less heat sink effect: allowing efficient ablation close to large vessels
propagate into fat and calcifications: leading to homogeneous coagulation necrosis
consistently higher intratumoral temperatures: cause larger and fast necrosis
faster ablation times: lower doses of sedatives might be required
larger tumor ablation volumes
