Derek first came to hospital when he was 14 years old when he started losing feeling in his hands and feet. He could barely walk or lift his arms, and breathing felt like it was through a straw.
He was diagnosed with an arteriovenous malformation, or AVM, a condition where tangles of blood vessels form in the body preventing oxygen from reaching nearby tissue. Derek's AVM was positioned near his lower brain stem and upper spinal cord.
His debilitating condition and ongoing treatment stopped him from attending school full time, instead regular hospital visits became the norm.
But as his condition worsened, clinicians knew they needed a new approach.
Research into a new liquid biopsy test showed promise for Derek as it could be the key in identifying a targeted treatment for his specific AVM, without the risk of life-threatening bleeding that other biopsies had.
Derek soon was part of a world-first clinical trial to use liquid biopsy for children and young people with AVMs, and based on its results, clinicians discovered a targeted treatment for his AVM.
Derek is 18 years old now, walking and breathing easy again. The treatment shrunk his AVM and diminished his other severe health symptoms.
His story is a testament to the importance of research collaboration in hospitals, showing that laboratory research into new biopsy methods can directly enable hospital bedside treatments.
