5 September 2018 - Hand surgeon Carlos Heras-Palou said his career "would have been finished" in six months without the treatment.
Carlos Heras-Palou, an orthopaedic surgeon at Royal Derby Hospital, was diagnosed with transthyretin-mediated amyloidosis.
The hereditary condition affects limb movement and other functions, and can be fatal in some cases.
The 53-year-old took part in a trial for patisiran, which blocks the activity of a gene in the liver.
Patisiran has now been licensed by European and UK regulators.
