Cerebral artery aneurysm Treatment in Prof. Dr. Özgür Kılıçkesmez

About the clinic

Cerebral artery aneurysm treatment at the clinic of Prof. Dr. Özgür Kılıçkesmez in Istanbul, Turkey, focuses on advanced endovascular techniques that avoid open brain surgery. Prof. Dr. Kılıçkesmez leads these procedures with over 25 years of experience and holds certification from the European Board of Interventional Radiology (EBIR). The clinic uses 3D digital angiography to provide precise treatment for complex vascular cases.

Advanced diagnostics for brain aneurysms

The clinic uses detailed imaging to plan every procedure. This helps the medical team see the exact shape and size of the aneurysm before starting treatment. Available diagnostic tools include:

Computed tomography (CT). This scan provides clear images of the brain structure.
Magnetic resonance imaging (MRI). This is used to detect vascular abnormalities without radiation.
Cerebral angiography. The clinic uses 3D rotational digital subtraction angiography for a detailed look at blood flow.

Endovascular treatment options

Prof. Dr. Özgür Kılıçkesmez specializes in minimally invasive methods. These treatments involve reaching the brain through a small incision in the groin or wrist. These procedures typically require only 1–2 nights of hospital stay.

Endovascular coiling. The doctor inserts platinum coils via a microcatheter to fill the aneurysm. This stops blood from entering the sac.
Stent-assisted coiling. For aneurysms with a wide neck, a stent helps keep the coils in place. This method reduces the chance of the aneurysm returning.
Flow diverter stent placement. This specialized stent redirects blood flow away from the aneurysm. It is often used for complex cases where coiling is not suitable.

Expertise of Prof. Dr. Özgür Kılıçkesmez

Prof. Dr. Özgür Kılıçkesmez is a professor of neuroradiology with international training. He served as a clinical fellow at King's College Hospital in London. His research is published in over 90 international journals and has earned over 2,500 citations. He was also the founding interventional radiologist at the Çam and Sakura City Hospital.

Prof. Dr. Kılıçkesmez previously headed the Interventional Radiology Department at IEAH. He currently leads the department at Memorial Göztepe Hospital.

Interventional Neuroradiology and Spine Care

Specialists treat neurovascular conditions using endovascular techniques. These procedures address brain aneurysms and strokes through the groin or wrist. By working from within the blood vessel, surgeons avoid traditional open-skull surgery.

Spinal care follows individualized protocols for compression fractures. The team evaluates fracture age and pain severity using MRI and CT scans. They perform vertebroplasty and kyphoplasty – procedures that use fluoroscopy to guide bone cement injections into damaged vertebrae.

Interventional Oncology and Embolization

The clinic treats various tumors using non-surgical thermal ablation. Specialists select the method based on tumor size and location. Options include radiofrequency ablation, microwave ablation, and cryoablation to destroy cancer cells without large incisions.

Endovascular embolization targets several conditions:

Prostate artery embolization for benign prostatic hyperplasia symptoms
Thyroid artery embolization to reduce thyroid volume
Varicocele embolization to treat enlarged scrotal veins
Uterine artery embolization for fibroids

These procedures use microcatheters to selectively block blood flow to specific tissues or lesions.

Diagnostic Imaging and Safety

All treatments are planned using a full suite of diagnostic tools. The clinic uses MRI, CT, and digital angiography for precise procedural mapping. Ultrasound and dynamic fluoroscopy provide real-time guidance during interventions to protect healthy tissue.

Safety starts with individualized imaging evaluations. For liver procedures, the team performs image-guided percutaneous or transjugular biopsies. These methods allow accurate tissue sampling while minimizing bleeding risk.

Services for International Patients

The clinic provides medical services in several languages. Consultations and treatments are available in Turkish, English, German, Russian, and Arabic. Patients receive detailed recovery instructions and customized medication schedules after their procedures.

Specific follow-up protocols support long-term monitoring. Oncology patients undergo imaging every three months during the first year. The team also coordinates blood tests to track thyroid function or tumor markers after embolization.

The general surgeons I consulted because of the large thyroid nodules in my throat told me that the only solution was surgery and that my thyroid needed to be completely removed. However, because I was afraid of surgery, I didn’t want to lose my organ, and instead of giving up, I searched for alternative options and discovered the Interventional Radiology department and a non-surgical ablation method. As a result of my research, my path crossed with the valuable Prof. Dr. Özgür Kılıçkesmez, a specialist in his field. He successfully performed my ablation procedure in April while preserving my organ, and at my August follow-up we saw that my nodules had shrunk by 65%. If it weren’t for Prof. Özgür, I might be lying on the operating table right now and would have lost my organ. He is truly an excellent doctor in every sense; not only with his expertise, but also with the trust he gives his patients and his humane approach. Throughout the process, because of the attention he showed, I always felt very safe. I hope he becomes a source of hope for all patients like me who are afraid of surgery and feel helpless. I’m so glad you’re here, Doctor—endless thanks!

After our son, who was diagnosed with antenatal hydronephrosis, had an unsuccessful attempt with a stent, our path crossed with Eyüp Veli Küçük through the grace of “Hoca” and then with Özgür Hoca. The UVJ stricture was severe and was challenging the doctors. We spoke with different doctors for the operation. We found the fastest and most definitive solution with Özgür Hoca. Even though it was a difficult operation, he successfully saved our son’s kidney health. Before the operation, he said he would try to the very end even if there were only a very tiny opening at the orifice. He did what he said—he managed to place the stent. We are satisfied with him; may Allah also grant our thanks and satisfaction to our hoca.

My father, born in 1946, underwent an extremely successful minimally invasive brain surgery six years ago performed by our esteemed Prof. Dr. Özgür Kılıçkesmez. Thanks to his clear explanations before the operation, his gentlemanly manner, and his professional expertise, our family was able to get through this difficult process very comfortably. Despite the six years that have passed, my father’s health is very good. I’m glad our paths crossed—may his hands never fail. In a worrying process for patients’ families such as brain surgery, the depth of knowledge, experience, and calm approach of Dr. Özgür gave us great confidence. The expertise of our doctor and the care shown by his team are truly commendable. We sincerely thank him, my father, and our family for the value he has added.

At the hospital where I applied with my headaches and accompanying visual disturbance, examinations found two aneurysms in my brain with different sizes. Our paths crossed in Interventional Radiology with Dr. Özgür. He explained my disease and the treatment path to me, step by step, with all the details and risks, which put my mind at ease, and he laid out a clear treatment plan. He worked in perfect harmony with his team. I handed myself over to the process without fear, believing and trusting in it. The timing was planned appropriately, and I started my treatment. Using the catheter angiography method from the groin, my aneurysms were treated with a stent + coil. In April, I went for my 3rd-year follow-up, and everything was fine. All my aneurysms were treated, and I regained my health. I listened to what my doctor said, followed his advice, and got results from my treatment in an easy way. I sincerely thank Dr. Özgür and his team. No matter what your illness is, if your path crosses with Özgür, don’t worry—trust your treatment.
