What is stereotaxic surgery used for?
A stereotactic brain surgery is a surgical procedure where lesion, frequently a brain tumor, is removed with assistance of image guidance, that is previously obtained images (usually an MRI) are used to guide the surgeon to the exact location of the lesion to facilitate as accurate a pathway through the brain and safe
Who discovered the stereotaxic surgery techniques?
” Stereotaxic ” surgery began in 1908, when Sir Victor Horsley and Robert Clarke  introduced their new apparatus to allow them to insert a probe, blade, or needle under accurate control into a subcortical structure of a monkey or other experimental animal.
What are stereotaxic coordinates?
Stereotaxic Surgery is a technique used to locate and manipulate discrete areas of the brain using a coordinate system. The spatial relationship is expressed using 3 coordinates : Anterior-Posterior (AP),Medial-Lateral (ML),and Dorsal-Ventral DV.
What is a stereotactic device?
A stereotaxic device uses a set of three coordinates that, when the head is in a fixed position, allows for the precise location of brain sections. Stereotactic surgery may be used to implant substances such as drugs or hormones into the brain.
How do you use stereotaxic instruments?
Apply povidine/iodine to shaved area but protect the eyes from it. Mount the animal onto the stereotaxic apparatus by placing the ear bars into the ear canal and tightening into place. First mount one ear bar in the ear canal, and then hold it in place and slide in the other ear bar.
What does stereotaxic mean?
Definition of ‘ stereotaxic ‘ 1. of or relating to stereotaxis . 2. medicine. of or relating to precise localization of a tissue, esp in the brain.
What is SRS radiation therapy?
Stereotactic radiosurgery ( SRS ) uses many precisely focused radiation beams to treat tumors and other problems in the brain, neck, lungs, liver, spine and other parts of the body. It is not surgery in the traditional sense because there’s no incision.
What is stereotactic craniotomy?
This technique requires the use of a frame placed onto the skull or a frameless system using superficially placed markers or landmarks on the scalp. When either of these imaging procedures is used along with the craniotomy procedure, it is called stereotactic craniotomy .
What is stereotactic and functional neurosurgery?
The Joint Stereotactic and Functional Neurosurgery Section is dedicated to the treatment of functional disorders of the nervous system through the use of stereotaxy and other forms of surgical technology.
Where can I find Bregma?
Location. The bregma is located at the intersection of the coronal suture and the sagittal suture on the superior middle portion of the calvaria. It is the point where the frontal bone and parietal bones meet.
What is the Interaural line?
The term interaural line refers to a basic stereotaxic landmark for brain surgery in the days before noninvasive methods made possible the visualization of internal features of the living brain.
Where can I find Bregma mouse skull?
(A) The mouse skull , viewed from above. Bregma is visible as the intersection of the sagittal and coronal sutures, and lambda as the intersection of the sagittal and lambdoid sutures.
Is stereotactic radiosurgery painful?
In order to precisely direct the radiation beams, a frame is placed on the patients head. Local anesthetic is administered, and the frame is secured to the skull by four sterile pins; the only discomfort is during the administration of the local anesthetic.
What are the side effects of radiosurgery?
What are the risks of stereotactic radiosurgery? fatigue . skin problems, such as red, swollen, peeling, or blistering skin. hair loss in treatment area. difficulty swallowing. nausea and vomiting . headaches . swelling , especially of the brain.
What is the difference between SRS and SRT?
SRS is delivered in one high dose treatment. SRT delivers radiation therapy in smaller amounts over several treatment sessions. Both SRS and SRT deliver similar total doses of radiation, but SRT allows the healthy tissues time to recover between treatment sessions.
