Благодарим на лекарите, които поеха нашия случай, тъй като беше доста сложен
Имахме доста сериозно образование АВМ за което намерихме лечението в клиниката. Тъй като резултатът изисква време, все още не можем да преценим дали е било успешно лечението, но за сега всичко ни хареса. Надяваме се, че ще получим позитивен финален резултат без сериозни странични ефекти. Ще проследяваме състоянието след лечението в клиниката. Благодарим на лекарите, които поеха нашия случай, тъй като беше доста сложен, а също и на Алишер, който помогна с организацията на лечението.

Медицински персонал, освоен докторите не иска много да говори на английски.

We felt fully confident knowing we were in the hands of one of the best in his field
World-Class Neurosurgical Care and Compassion
We are profoundly grateful for the exceptional care provided by Professor Ilhan Elmaci. His expertise, professionalism, and compassionate approach were evident from our very first meeting. Professor Elmaci performed the surgery to remove a medulloblastoma with extraordinary precision and care, and we felt fully confident knowing we were in the hands of one of the best in his field. Beyond his remarkable surgical skill, Professor Elmaci took the time to explain each step of the process with clarity and patience. He was always available to answer questions and offer reassurance, treating both the patient and our family with deep empathy and respect.
A heartfelt thank you to Coordinator Alisher, who supported us at every step. He was always responsive, attentive, and truly dedicated to the patient’s well-being. From organizing the transfer and handling all special requirements to keeping the family updated and arranging medical needs, he made a difficult time much more manageable.
The hospital staff was professional, kind, and caring throughout. We deeply appreciate the high level of expertise and personal attention that made all the difference in this journey.

They brought our boy back to life
From the bottom of our hearts we would like to express our gratitude to our doctor Ilhan Elmachi and his whole team. We are from Uzbekistan and when we were diagnosed with arteriovenous malformation we realised that this is the most complicated pathology of brain neurosurgery. Our boy is only 17 years old and therefore it is understandable what grief fell on us. But thanks to the clinic manager Florence Alisher, we came across our respected doctor. The operation lasted 17 hours. Two days later our boy was already in the ward. 15 days later we were home. Our boy is healthy Ilhan Elmachi is a high professional. THANK YOU for the sensitive and caring attitude to us doctor and his team and nurses They brought our boy back to life. Such people are like stars in the desert gave us hope. All health and success in science. May Allah protect you.

We would strongly recommend this team to any foreigner visiting Turkey for treatment
I landed on Bookimed while searching for further treatment.. One Dr.Hilal got in touch with me and guided me through the different options available to us. We eventually settled on Florence nightingale hospital and immediately got in touch with Alişer, who walked with us through our preparation and arrival in Turkey as well as the hospital visits. He was kind enough to guide us on what was expected and was always available even at odd hours . The doctors at the Hosp led by Prof Elle and Prof Yusef, treated us with utmost professionalism. They calmly guided us through the process and made us understand what we are dealing with. They were not quick to rush into any interventions.. we felt very safe in their hands. A special thanks to Simaza our interpreter, you are a wonderful human being. Blessings lady. To The Professors, all medical professionals at the hospital, we are grateful. Hilal, Alişer and Simaza you the best. We would strongly recommend this team to any foreigner visiting Turkey for treatment..
we were happy! Blessings
