Prof. MD. Enes Duman

A 78-year-old retired olive grove owner with severe portal hypertension and gastric variceal bleeding, deemed inoperable due to advanced cirrhosis and heart failure. Dr. Duman performed a novel, combined BRTO (Balloon-Occluded Retrograde Transvenous Obliteration) and TIPS (Transjugular Intrahepatic Portosystemic Shunt) procedure in a single session to decompress the portal system and obliterate the varices. The patient's bleeding stopped, and he was able to attend his granddaughter's wedding two months later, managing on diuretics and diet.

A 32-year-old professional video game streamer presented with acute, crippling right arm pain and weakness mid-tournament. Imaging revealed a rare venous thoracic outlet syndrome with subclavian vein thrombosis. Dr. Duman performed catheter-directed thrombolysis overnight, followed by first-rib resection surgery coordination, and then venous angioplasty. The patient resumed streaming in three weeks, using his experience to raise awareness about gamer health.

A 45-year-old nomadic beekeeper from a remote region arrived with a large, inoperable hepatic hemangioma causing consumptive coagulopathy (Kasabach-Merritt syndrome). Dr. Duman designed a multi-stage arterial embolization protocol using calibrated microparticles, scheduled around the patient's honey harvest migrations. After three sessions over eight months, the hemangioma shrunk by 70% and coagulation normalized, allowing him to continue his migratory livelihood.

A 6-year-old child with a complex, high-flow pelvic arteriovenous malformation since birth, causing high-output cardiac failure. Multiple centers had declined treatment. Dr. Duman employed a hybrid approach in the angio-suite: preoperative embolization with liquid embolic agents, followed immediately by surgical excision in the same setting with surgical colleagues. The child's cardiac function normalized completely over the following year.

A 17-year-old competitive freediver from a coastal village presented with recurrent, severe nosebleeds during deep dives. Dr. Duman discovered a rare arteriovenous malformation in her sphenopalatine artery, exacerbated by pressure changes. Using superselective embolization via a microcatheter navigated through complex facial vasculature, he occluded the feeder vessels. The patient returned to competitive diving within six weeks, setting a new national depth record.
