Two clinic wards, up to one hundred patients from around the world and five to six operations per day, usually cases of strokes, brain tumours and bypasses. His instruments are tiny, his success huge. In his book, brain surgeon Prof. Dr. Vajkoczy recounts spectacular cases and unusual methods, such as operating while the patients are fully conscious, and the merciless race against the clock when he performs a brain bypass. It is a candid and fascinating self-portrait of the doctor who the media call “the man for fine work” and whose greatest quality is his humility. Every day, he experiences how patients expect him to perform miracles. And at the same time, he knows how fine the line between life and death is when he is operating on an open brain, where a percent of a millimetre can be the difference between success and failure.
