The goal of this clinical trial is to learn whether an exoskeleton-supported radiation protection system can reduce radiation exposure and musculoskeletal strain in vascular surgeons during endovascular aortic repair procedures, compared with standard lead aprons. Researchers will compare procedures performed with exoskeleton-supported protection and procedures performed with standard lead aprons. Radiation exposure, physical strain, fatigue, and discomfort will be assessed during and after procedures.
