ablation definition medical urinary
Regrowth of the endometrium may occur after you have endometrial ablation. This procedure is not recommended if you have a high risk for endometrial cancer. Do not consider this procedure if you plan to become pregnant in the future. ablation. n. 1. (Surgery) the surgical removal of an organ, structure, or part. 2. (Aeronautics) the melting or wearing away of an expendable part, such as the heat shield of a space re-entry vehicle on passing through the earth's atmosphere. 1. the act or process of ablating. 2. the removal of organs, abnormal growths, or harmful substances from the body by mechanical means, as by surgery. 3. the erosion of the protective outer surface (ablator) of a spacecraft or missile due to heat during reentry through the atmosphere. (ă-blā′shən). Similarly, repeat ablation procedures for recurrent atrial fibrillation generally involve more extensive ablation than do initial procedures. As many as 30% of patients will require a follow-up (repeat) procedure due to recurrence of atrial fibrillation or to developing atrial flutter. Policy BCBSNC will provide coverage for catheter ablation as a treatment for atrial fibrillation when it is determined to be medically necessary because the medical criteria and guidelines shown below are met. Benefits Application This medical policy relates only to the services or supplies described herein. The need for repeat procedures may, in part, depend on clinical characteristics of the patients (age, persistent vs. paroxysmal atrial fibrillation, atrial dilatation, etc.) and the type of initial ablation performed. Repeat procedures are generally more limited than the initial procedure. Endometrial ablation is a procedure that destroys (ablates) the uterine lining, or endometrium. This procedure is used to treat abnormal uterine bleeding. Sometimes a lighted viewing instrument (hysteroscope) is used to see inside the uterus. Endometrial ablation can be done by: 1  Laser beam (laser thermal ablation). 2  Heat (thermal ablation), using: 3  Radiofrequency. 2. ablation-the erosive process that reduces the size of glaciers. eating away, eroding, erosion, wearing, wearing away - (geology) the mechanical process of wearing or grinding something down (as by particles washing over it). However, the majority of patients who are atrial-fibrillation-free at 1 year remain atrial-fibrillation-free at 5 to 6 years. Rates of complications following ablation remain somewhat uncertain. Death is rare, and a 2013 systematic review including over 83,000 patients reported a major complication rate of 2.9%. When Catheter Ablation as a Treatment for Atrial Fibrillation is not covered Transcatheter ablation to treat atrial fibrillation is considered investigational for all other indications not listed above. Policy Guidelines There is not one single procedure for catheter ablation, but several variations.
It is the surgical removal of an organ, structure, or part.
