Assoc. Prof. M.D. Ahmet Arnaz

I'm a 78-year-old retired history professor with severe peripheral artery disease that left me barely able to walk to my mailbox. Three other surgeons told me amputation was inevitable due to my age and complex blockages. Dr. Arnaz studied my angiograms for an hour, tracing vessels like ancient maps, and proposed a novel hybrid procedure combining endovascular and open techniques he'd pioneered. The 7-hour surgery felt like a historical restoration of my circulation. Six months later, I'm tending my rose garden again. He doesn't just treat vessels; he preserves lives worth living.

Our 9-year-old daughter Elif was born with Klippel-Trenaunay syndrome, her left leg swollen twice its size with vascular malformations. We'd seen 11 specialists across Europe who offered only palliative care. Dr. Arnaz created a 3D printed model of her vasculature, explaining to her how he'd 're-route the rivers' during a series of staged procedures. He spoke to her about space exploration during pre-op, making her laugh. After three meticulous surgeries, she wore matching shoes for the first time last week. His combination of technical genius and profound humanity is something I've never witnessed in medicine.

I'm a 42-year-old marathon runner who collapsed mid-race with a ruptured popliteal artery aneurysm—a ticking time bomb I never knew I had. Rushed to Acibadem, Dr. Arnaz performed emergency endovascular repair at 2 AM. What stunned me wasn't the life-saving precision (though that was remarkable), but his 5 AM visit to explain he'd used a custom stent graft configuration to preserve my running future. At follow-up, he analyzed my gait cycle to ensure surgical success wouldn't compromise my biomechanics. He treats emergency cases with the foresight of long-term partnership.

As a 55-year-old fisherman with a decades-old arteriovenous fistula in my forearm from dialysis, I developed such severe steal syndrome that my hand turned blue and numb. Dr. Arnaz didn't just revise the access; he spent an afternoon understanding the hydraulic dynamics of my specific fistula, then designed a 'banding' procedure using intraoperative flow measurements to calibrate the perfect restriction. He explained it like adjusting sail tension. My hand is pink, my dialysis works better, and I can tie fishing knots again. He approaches every vessel like a unique engineering puzzle deserving a custom solution.
