A 24-year-old female competitive cyclist presented with sudden onset of severe left leg pain and pallor during a training session. Dr. Kaya diagnosed acute external iliac artery endofibrosis, a rare condition in endurance athletes. Using intravascular ultrasound, he performed a meticulous endarterectomy with patch angioplasty. The patient returned to professional cycling after 3 months of monitored rehabilitation, setting a personal best time.

An 82-year-old retired railway worker with severe dementia and limited family support was admitted from a nursing home with a ruptured mycotic abdominal aortic aneurysm secondary to untreated Salmonella bacteremia. Dr. Kaya coordinated with geriatric specialists and, considering the patient's advanced directives, performed an emergency endovascular aneurysm repair. The patient survived the acute event and returned to the nursing home with palliative care support, living another 11 months.

A 38-year-old vegan software developer presented with exercise-induced calf pain initially dismissed as muscular. Dr. Kaya identified bilateral popliteal artery entrapment syndrome through dynamic angiography. He performed a unique bilateral gastrocnemius muscle head resection and artery reconstruction in a single staged procedure. The patient made a full recovery, later developing a mobile app for vascular health tracking.

A 7-year-old boy with Kasabach-Merritt syndrome (a rare vascular tumor disorder) was referred after failed embolization elsewhere. Dr. Kaya designed a multidisciplinary approach involving pediatric oncology and interventional radiology. He performed staged surgical debulking of a massive retroperitoneal hemangioma, controlling the consumptive coagulopathy. The child required 18 months of follow-up but achieved complete remission.
