Cutting-edge neuro-microscope helps five-year-old beat strokes in WA

Riley Shawcross, aged five, was diagnosed with a rare ACTA2 gene mutation that causes multisystemic smooth muscle dysfunction syndrome, putting her at high risk of strokes. Between July 2024 and early 2025 she experienced over 25 transient ischaemic attacks, prompting doctors to consider surgical intervention. In July 2025 she underwent a right-side brain revascularisation, and shortly before a second operation the hospital received a state-of-the-art neuro-microscope financed by the Perth Children’s Hospital Foundation.

Surgeon Edward White said the microscope’s half-millimetre resolution, AI-driven imaging and robotic assistance let the team tailor the surgery to Riley’s unique vascular anatomy, preserving critical vessels and noting new growth. Since the procedures, Riley has not suffered a stroke for more than four months, and her parents express deep gratitude. The technology is expected to be used in the majority of neurosurgeries at the hospital, enhancing outcomes for many pediatric patients.
