Assist. Prof. M.D. Gökhan Arslanhan

As a 24-year-old professional freediver, I noticed my right hand turning pale and cold during deep dives. Multiple specialists dismissed it as Raynaud's. Dr. Arslanhan diagnosed me with a rare thoracic outlet syndrome variant compressing my subclavian artery only in specific arm positions. His minimally invasive robotic surgery corrected the anomaly. Six months post-op, I set a new national depth record—my hand stays warm at 40 meters.

My 82-year-old grandmother, a retired lacemaker, developed a pulsating abdominal mass. Other hospitals deemed her too frail for open surgery. Dr. Arslanhan pioneered a custom fenestrated endograft procedure at Acibadem Maslak, preserving blood flow to her kidneys and intestines through microscopic side-branches. She was weaving again in three weeks, calling the stent her 'invisible thread.'

During a business trip to Istanbul, I (45, tech CEO) experienced sudden blindness in one eye. Rushed to Acibadem Maslak, Dr. Arslanhan identified a carotid artery dissection showering clots to my retina—a ticking time bomb for a major stroke. He performed an emergency carotid stenting under conscious sedation so I could communicate critical passwords to my team mid-procedure. Vision restored, stroke averted.

Our 7-year-old daughter had Klippel-Trénaunay syndrome with painful venous malformations covering her left leg. Dr. Arslanhan designed a staged treatment combining laser ablation, sclerotherapy, and compression therapy tailored for a growing child. He explained each step using dinosaur analogies. After two years, she proudly wore shorts for the first time at a school picnic.
