Microvascular decompression statistical analysis
I am sure most people reach a stage when they want to look in detail at what actually happened medically to their nearest and dearest. There is always the question of ‘why it happened’ but it’s unlikely we will ever really know why Anita suffered a cerebellar pontine angle bleed, leading to brain damage, after a simple operation. I can fully understand how some people become obsessed with medical information after such an occurrence like some unsolved crime. For various reasons I have recently begun for the first time to at least think about what happened in Addenbrookes hospital. Anita’s medical notes from that period number well over a thousand pages, an ample novel for those in pursuit of forensics.
As a means to educating myself on the operation I have just read a medical journal on the lessons learned from 4400 Microvascular Decompression operations that talks through operation technique. It is an American article and I confess I am not totally clear on the differences in technique from country to country. On reading, it appears to follow the same procedures that Anita’s OP followed. The article draws out some useful statistical analysis on the complications of the surgery.
Of the 1,995 operations performed since 1990, cerebellar injuries declined to nine cases (0.45%)
Anita would fit into this category and if you add in the further complications she has also suffered and the damage done it put’s her in a very unfortunate, small, statistical group. Looking at the positives, it backs up the reason to have the operation. You should never ever have regrets in life, but as I type, and I hear her disturbed, brain damaged sleep ramblings, I wonder why it’s always the special people that get the hardest time.


The problem is that every time they operate on each of these muscles it can effect the blood supply to the eye through them. Because Anita will have had all muscles worked on there is a risk that the blood supply to the eye could be affected. This could cause a lack of supply leading to problems, potentially a loss of sight. You can see from the second photograph how much anita’s eye is turned in. It also demonstrates the two previous operations, a gold weight in the eyelid and plastic surgery on the lower lid.
