Lars Lönn

Lars Lönn is a Clinical Professor in the Department of Clinical Medicine at the University of Copenhagen's Faculty of Health and Medical Sciences, based at Rigshospitalet in Copenhagen. His clinical and research work focuses on interventional radiology techniques and medical education.

His research centers on expanding endovascular treatment applications, including percutaneous transluminal angioplasty (PTA), stent placement, embolization techniques, and endovascular prosthetic insertion. He evaluates these against conventional diagnostic methods like duplex ultrasound, arteriography, and 3D CT scanning. A major emphasis is medical simulation training for endovascular procedures, with projects examining simulator-based training effectiveness across clinical scenarios in collaboration with CEKU, vascular surgery, cardiology, and radiology departments.

Recent publications reveal expertise in prostatic artery embolization for benign prostatic hyperplasia, genicular artery embolization for knee osteoarthritis, and AI-driven lung perfusion quantification in pulmonary embolism, demonstrating strong trends in vascular interventions, embolization therapies, and advanced imaging analytics integration.

Professor Lönn leads key collaborative initiatives including the Copenhagen Mesenteric stent study (COMESS) comparing stent treatments for mesenteric ischemia and the TUMT-PAE-1 trial evaluating alternatives for urinary symptoms. His work emphasizes interdisciplinary coordination across trauma surgery, anesthesiology, and specialty departments to optimize acute care protocols and patient outcomes.
