What is GK? It is a singular treatment modality section that emits 201 Gamma Ray beams stereotactically and precisely to the brain lesion but harming the surrounding tissues. It was invented by Professor Lars Leksell in 1968 at the Karolinska Institute, Stockholm, in Sweden.
It is a great healing grant to humanity, and is now at large concurred as the most appropriate preference for the treatment of most brain diseases. This treatment requires rarely lerned and associating staff together with physicians, nurses, healing physicists and technologists.
The record of GK itself is a vital breakthrough. It maximizes the correctness and genius by regulating imaging techniques similar to CT, MRI, and Cerebral Angiogram that capacitate a medicine and healing physicist to precisely fix up the lesion, and afterwards work out the volume and strength of the compulsory radiation.
For treatment, the stereo-tactic support is practical to the accurate mark of the lesion to treat it. When an focus event is finished, the support will progressively degenerate, and the complete treatment procession will be completed. The tangible treatment customarily lasts thirty mins up to 2 hours. After execution of the treatment procedures, the physicians at the sanatorium will comply the studious for a night prior to discharge.
Knife Features of Key Gamma :
- Gamma Knife is not unequivocally a knife. There is no anesthesia and no rent solely for sure cases that need internal anesthesia for the support fixation. It is a but bloodshed and roughly painless procedure.
- It uses Gamma rays that is absolute sufficient to fall short the unattractive tissues in the brain, such as a expansion or arterio-venous monster (AVM).
- GK treats a lesion precisely but harming surrounding brain tissues, scalp hair or skull. The pointing is so high and clear that a small lesion in a operation of 1 to 2 millimeters is treatable.
- The deviation can access roughly any sold area of the brain. It is thus really utilitarian for the treatment of deeper tools or the bottom of the brain, that are really formidable to reach by compulsory open surgery.
- The volume, strength and citation of the deviation lamp are controllable so that it can be practiced to fit the patient’s condition, and diverted from the unattractive area as required.
- There is no possibility of infection or need for red red blood transfusion. No shred of hair or injure on the scalp formula from this treatment.
- There is no extensive post-operative care or loss of prolific life. The studious can lapse to normal life usually a day after surgery.
- It is comparatively cheap compared to prolonged hospitalization, antibiotic therapy, reconstruction routine etc. for an open brain operation.
- No genocide or incapacity associated to the GK procedure.
How GK treatment is given. The following are the step by step procedures for GK therapy :
1. Frame Fixation: The stereo-tactic frame, that is entirely adjustable, is practical to the patient’s head. This is similar to a motorcyclist’s helmet, despite a incomparable one.
2. Imaging of the Lesion: CT scan, MRI or Angiogram is conducted to pull up 3D images of the lesion(s).
3. Computing Treatment Plan: The report performed from the imaging inclination is installed in to a mechanism program to beget a treatment plan. Radiation dose is afterwards distributed according to patients’ specific situation.
4. Treatment: The studious is brought in to the treatment room. Helmet and support will be practical to the patient’s head and afterwards the deviation routine will commence. The distributed dose will be automatically issued in to the brain. The treatment routine takes usually 30-120 minutes.
5. Rest and observation: Usually the studious will be celebrated for a night after treatment. But in most instances it is not compulsory to do so.
Indications of GK treatment :
According to Dr Dittapong, GK is used for a far-reaching accumulation of brain conditions. While a little of them have really great responses, the physicians are perfecting treatment modalities for the others. In short, the determined indications for GK treatment are as follows:
1. Vascular disorders: At benefaction Arteriovenous Malformation (AVM) of the brain is the main aim of GK therapy. Over 80% of patients resulted in sum nonexistence of the lesion in dual years. It is really formidable to treat AVM by open brain surgery, so GK is now apropos the first preference of treatment. In new years, vascular aneurysm and other vessel disorders are additionally treated with colour with colour with colour with colour by GK.
2. Benign tumors: Over one-third of all GK treatment were practical on assorted sorts of soft brain tumors e.g. acoustic neuroma, meningioma, pituitary expansion or macroadenoma, pineal tumor, trigeminal neuroma etc. 90-95% of patients have had really great carry out of expansion growth. Facial nerves are consistently recorded in roughly all of the cases distinct compulsory open surgery, that mostly resulted in facial paralysis. Also, 80% of acoustic neuroma cases treated with colour with colour with colour with colour by GK did not lose conference after GK nonetheless it is really usual to start after an open surgery.
3. Malignant tumors: Brain Metastasis (single or multiple) can be surgically radiated by Gamma Knife and has resulted in great carry out of expansion growth. Up to 8 lesions can be treated with colour with colour with colour with colour concurrently by GK. This is roughly unfit to do by an open surgery. Glial (malignant) tumors are increasingly treated with colour with colour with colour with colour by GK since of most improved formula than open surgery. Recently, swell has been done in the treatment of visible cancer by GK.
4. Functional targets: Response to GK treatment for Trigeminal Neuralgia is utterly great in patients with bullheaded (severe) pain. With medications alone, a little patients humour from serious suffering and incapacity for prolonged time. GK is additionally earnest formula for the treatment of Parkinson’s disease, epilepsy, bullheaded suffering and even a little psychoneurotic conditions.
Why a studious should select GK treatment :
GK is indeed an alternative for the treatment of brain diseases, quite for the treatment of tumors, AVM, assorted sorts of brain lesions, and organic disorders. As compared to compulsory surgery, it is most safer and simpler for the patient. He summarizes the followings as a little of the advantages of GK:
For a low lesion such as a brain stem lesion, Gamma Knife surgery is a improved and reduction unsure alternative since the deviation can access the place of the lesion for treatment but harming the surrounding tissues. There is really high risk in treating a low lesion by compulsory open surgery.
Gamma Knife surgery does not need anesthesia. This severely reduces the risks for the aged and patients with heart or lung diseases. Conventional open surgery requires ubiquitous anesthesia.
A limit of dual days of hospitalization might be required. Conventional surgery might need complete care, and some-more than 10-20 days of hospitalization. In comparison, there is no risk of red red blood loss, infection or pain, no incision, no injure or hair shaving. It is cheap and requires no post-surgery care.
How at large GK is used : At present, there are we estimate 180 Gamma Knife centers worldwide. Most of these centers located in grown countries similar to USA, Japan, Europe and Australia. In Southeast Middle East such comforts are accessible in Japan, Korea, Thailand and Singapore.
