Great Ormond Street: Mend My Brain

Documentary series based at the pioneering London children's hospital. This episode looks at children with serious diseases of the brain, and the doctors who have no option but to undertake seriously risky treatments. Trinity is seven years old and has just been diagnosed with a rare tumour resting on her brain stem, which controls vital functions. Her parents must decide whether to go ahead with surgery and controversial proton beam therapy. Jack is 16 and suffers from severe epileptic seizures which cannot be controlled through medication. The team can offer radical brain surgery which could cure him but it carries serious risks. We follow Dr Adam Rennie, a consultant interventional radiologist, as he takes on the treatment of two very young children. Dr Rennie is one of only three doctors in the country capable of carrying out the procedure. One third of his patients will not survive the operation, one third will suffer a minor bleed in the brain, one third will be cured.
