Ablative Therapies

Microwave Ablation is an ablative therapy that produces coagulation of soft tissue during the procedure.

Microwave ablation (MA) uses microwave energy and an antenna to cause coagulation of tissue by creating heat through friction and vibration of water molecules in the cells.

The advantage of MA over other heating systems, such as RFA, is that the microwave technique is quicker and does not cause collateral damage. It can be completed in 10 minutes.

Microwave Ablation can be performed through a needle (percutaneously), through small openings in the skin (laparoscopically), or through an incision in the abdomen. For more information about these techniques, see RFA .

Side Effects: Many patients experience a low grade fever and pain for a few days following the procedure. Major complications include liver abscess , bile duct injury, infections, bleeding and skin burn.

Recovery: If the percutaneous method is used the patient will usually go home the same day. If a laparoscopic procedure is selected then the patient often goes home the following day. An open surgical procedure requires that an incision be made in the abdomen, general anesthesia is used, and the recovery time will be longer.
