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.

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.

If in your country it’s hard to find experience with complex medical cases, the best and most reliable choice is Florence Nightingale Hospital

Our heartfelt thanks to Florence Nightingale Hospital My wife and I would like to share our sincere gratitude to the clinic and its amazing staff. First of all, a huge thank you to our coordinator Alisher. He organized everything — hotels, transfers, and all the logistics — at the highest level. Everything was perfectly arranged. We are truly grateful for his care and professionalism. He was always by our side, and even when we were back home in Latvia, he stayed in touch and supported us every step of the way. The attitude and professionalism of the doctors and medical staff were outstanding. As for the treatment — my diagnosis was a brain tumor located in a very delicate and complex area where surgery is extremely challenging. They managed to remove almost everything! The operation was performed by Professor Ilham Elmaci, a brilliant and highly experienced surgeon, together with his exceptional team. They did an amazing job. What impressed us most was how seriously the whole team approached their work — every morning, even on weekends, almost the entire medical team came to check on me. We would also like to thank Dr. Azat Mustafayev, a wonderful doctor who truly understands his patients and is always available and supportive. And, of course, our special thanks to all the nurses and medical staff who cared for me, helped me, and patiently put up with me! 😂 If in your country it’s hard to find experience with complex medical cases, the best and most reliable choice is Florence Nightingale Hospital. Best Regard Alexandrs and Kristina

All was cool.
