On Tuesday, 11 December 2001 I had Stereotactic Radiosurgery At the Prince of Wales Hospital My tumour was not suitable for treatment by surgery as the site was in close proximity to important brain structures; previous treatment was Endoscopic stereotactic resection of pituitary tumour the Surgeon was Dr Kwok, Dr Havas and Dr Jeffree Date: Tuesday, 22 May 2001 I had a single high dose of radiation in one day as my lesion was less than 3 cm in size although on the Pituitary gland is was far enough away from the optic (visual nerves). The surgery was done as an out patient; I was wide awake during the entire procedure. Although the risk of serious damage does exist, these are usually less than 5% as much lower dose of radiation is given to the surrounding brain. The Disadvantage is the benefit can take weeks to months to show although the lesion should not grow during that time. The Procedure: I had A brief (MRI) scan (10 mins) a week prior to the treatment.
Fitting The Frame was the worst part of the hole procedure After having a local anaesthetic into the skin, the frame was attached to my skull bone and remained there for 9 hours to allow for the Planning to take place
While the frame looks scary,” it is made of a lightweight alloy that only weighs a few kilograms.
With ring on my head I had a CT scan enabling the doctors to determine the exact co-ordinates as the Treatment relies upon developing co-ordinates, to show exactly where my lesion is and important brain structures are the metal ring is a reference plane. The frame can be seen on the imaging equipment and provided Radiosurgery staff with an exact set of coordinates so that the lesion or tumour is targeted precisely.
The Radiosurgery was the shortest component of the procedure only taking 40 minutes. The head of the Linear Accelerator moved across my head while the X-Ray beam zeroed in on the target (I Hope). The Treatment was divided into segments with the table I was on being moved to a different position for each segment. After the treatment the head ring was taken off, by unscrewing the pins and I was able to go home with no immediate side effects bar a sore head. Top Follow Up My Follow Up be done by referring specialist Doctor R Smee, Doctor B Kwok, Doctor A Steinbeck, Doctor Dudley O’Sullivan, and My GP Doctor Ross Price. This will range from blood tests for pituitary hormones and scans of the tumour and the pituitary gland. Top Information:
