How Dr. Aygün works with international patients

Dr. Aygün consults in Turkish and English, and interpreters can be arranged for families who speak other languages. The Acibadem international patient team coordinates the collection of prior reports and imaging, such as MRI, CT, X-ray or ultrasound reports, laboratory and pathology results, operative notes and discharge summaries, and arranges appointments and the hospital visit. A first consultation typically covers the child’s history and symptoms, a review of existing imaging and previous treatments, a clinical examination, and a discussion of the available options. Video consultation is available for international patients who wish to discuss a case before traveling.
