Prior to Procedure
Description of the Procedure TOP
The exact steps of the procedure will depend on where the tissue is located. The tool will be a probe that is applied directly to the area or passed through a catheter to the area. Imaging devices such as a CT scan, ultrasound, or MRI scan will be used to help guide the doctor to the area.
A small amount of electricity is passed through the tube which heats and destroys the selected tissue. The probe may be repositioned to destroy other areas of tissue.
Immediately After Procedure TOP
You will be monitored for 2-3 hours after the procedure.
How Long Will It Take? TOP
About 10-60 minutes
How Much Will It Hurt? TOP
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure will depend on the location and amount of tissue that was involved. Discomfort during recovery can be managed with medications.
