### input:
My sister, 39 yrs old was diagnosed a month back after one episode of seizure, with AVM in Left parieto occipital region of 1.5cm lesion with surrounding parenchymal oedema. Has been scheduled for cyberknife radio surgery this week and taking Levilpil 500 twice a day.Today she is having severe headache and bodyache on right side which is causing us worry. What precautions needs to be taken and is it a medical emergency situation?

### output:

Dear Concerned., Thanks for writing to us. In a c/o Cerebral Arms, in addition to Cybercafe, radiological embolization as an adjunctive therapy also. The Cybercafe allows delivery of high doses of targeted radiation with sub-millimeter accuracy, such that the lesions surrounding normal brain is subjected to very minimal harm. Such accuracy is critical for preserving as much brain function as possible. Most patients experience minimal recovery time and can return to normal activities following their treatment. Depending on the tumor type, size and location, many patients need only one treatment with the Cybercafe to destroy their tumor. Before the Cybercafe Surgery., the patient will be admitted for observation, then taken for CT navigated embolisation procedure for reducing the blood supply the size of the lesion. Before a patient is treated he or she may undergo a series of tests such as MRI, functional MRI, CT, and CT angiography. A multidisciplinary team of physicians including a neurointerventionalist, neurobiologist, neurosurgeon, and stroke neurologist carefully review this data to propose the best plan. The process of embolization is done under general anesthesia. An artery in the groin is punctured and catheterized so that guide catheter is pushed up to the neck and up into blood vessels supplying the AVM. Embolus producing agents are then injected into blood vessels supplying the AVM so that the clot artificially produced will block blood supply to AVM and the same regresses in size. As an elective procedure the patient will stay for 03-05 days. The embolisation is done in stages to prevent thrombosis and hemorrhages from occurring in normal parts of the brain. After regressing of AVM lesion, adjunctive Cybercafe therapy and Radiation therapy is done to achieve total removal of AVM. Levipil 500 mg (Levitiracetam)is an antiepileptic Chat Doctor.
