The word "Ablation" stems from the Latin word Ablatus meaning "carried away". In most cases, however, ablative brain surgery does not involve removing brain tissue, but rather destroying tissue and leaving it in place. [1] The lesions it causes are irreversible. There are some target nuclei for ablative surgery and deep brain stimulation.
If a benign or malignant brain tumor is suspected to be the cause of seizure activity, surgical removal of the tumor may be indicated. The approach and technique is case-dependent. One study of supratentorial brain tumors in children less observed a dramatic reduction in the severity and frequency of seizures at one and four year follow-up.
Thalamotomy is a complex procedure performed by specialist neurosurgeons. It is mostly indicated in cases of stroke, damage to third ventricle of brain, brain hemorrhage, accidents leading to head injury, oedema around thalamus, subdural hemorrhage, and cerebrovascular accident. There is also some evidence in thalamocortical dysrhythmia.
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
An ablative dose of radiation is thereby sent through the tumor in one treatment session, while surrounding brain tissues are relatively spared. Gamma Knife therapy, like all radiosurgery, uses doses of radiation to kill cancer cells and shrink tumors, delivered precisely to avoid damaging healthy brain tissue.
Former U.S. Open champion Gary Woodland said Wednesday he will have surgery to remove a lesion found on his brain. Woodland, a four-time PGA Tour winner, announced on social media he was diagnosed ...
Scruggs was detained for alleged possession of a controlled substance, according to prison records. Scruggs died from a seizure secondary to left frontal lobectomy due to a traumatic brain injury (from a motor vehicle accident a decade prior), according to the medical examiner. Jail or Agency: St. Louis County - Dept. of Justice Services; State ...
Thus, DBS is thought to create an 'informational lesion', [10] which can be switched off by turning off the DBS device, i.e. is largely reversible. This is a strong advantage compared to permanent brain lesions that are also applied to similar targets in similar conditions in the field of ablative stereotactic surgery.
