What is microwave ablation?
microwave ablation has become an increasingly common, less invasive method of surgically eliminating pathological or abnormal growth in the human body targeted exposure to microwave radiation. From the first person to scratch itching with a nail to an ophthalmologist, who can restore vision by shading the corneal layer with a laser beam, surgical removal of unhealthy biological tissue is one of the basic medicine. Although there are other methods of ablation - old and new - safely controlled microwaves have proved to be a viable tool of surgery for many medical disorders. Ablation
is the removal of the material from the surface of the object. Microwaves are electromagnetic radiation just behind the infrared spectrum, with frequencies sufficiently narrow to affect the mass at the molecular level. Microwave ablation surgery uses devices capable of generating microwaves that destroy unwanted cells in an allocalized energy field. There are other alternative ablation teesChicks, including cryoablation with freezing coolant, alternating current radio frequencies and high -frequency ultrasound vibrations. Only a doctor after consultation with an intervention radiologist can determine whether microwave ablation will be the best therapy for specific health.
Radiology has already been applied to medical purposes for several decades, but only when modern technology has improved the means of delivery that its practical use in surgery accelerated. The energy output is now focused and controlled on a small area; Energy generators are portable. The probes have been miniaturized to allow minimally invasive surgical introduction through a catheter or endoscope. Computer tomography (CT) Scanning and X -ray tomography enable interior instructions with accuracy aim to even small, prerakovinous tumors.
typical microwave ablation machine will consist ofA generator whose frequency, power and duration can be controlled to affect the size and speed of tissue ablation. It is connected by a thin, flexible conductor to the applicator, whose tip is a small microwave, usually one -off. The terminal antenna radiates microwave energy in a small, roughly spherical field in which water molecules vibrate in compassion and produce heat sufficient for "cooking" and killing live human tissue. Depending on specific treatment, dead tissue may remain like scarring, it can naturally separate and be excluded by the body, or the monitoring procedure may be required to remove the tissue.
While older and improved techniques of surgical ablation, including open procedures for abrasion or excision, the operating room prevails, increasing success of microwave thermotherapy has seen its wider application in many copical Fields. The method is a frequent possibility for endometrial ablation to control excessive bleeding and other disorders of the female uterus. It's another treatment tool for ONKology in a difficult fight against cancer. Microwave ablation surgery is even used endoscopically through three small chest cuts to actively beat the hearts of patients who are not calm in general anesthesia for the treatment of atrial fibrillation and other heart disorders.
