Kirurgiska förfaringssätt för behandling av kärlsjukdomar.
In medicine, a surgical operation, or simply "operation," refers to a medical procedure in which a doctor manually corrects an injury, disease, or abnormality using invasive techniques, such as instruments, cameras, or machines that assist in the visualization and treatment of internal structures. This may involve cutting, scraping, or removing tissue, bones, or other bodily components, and often requires anesthesia to prevent pain and discomfort during the procedure. The specific type of operation is determined by the nature and location of the problem being addressed.
