Vascular surgery is a surgical subspecialty in which diseases of the vascular system, or arteries, veins and lymphatic circulation, are managed by medical therapy, minimally-invasive catheter procedures, and surgical reconstruction.
The specialty evolved from general and cardiac surgery as well as minimally invasive techniques pioneered by interventional radiology. The vascular surgeon is trained in the diagnosis and management of diseases affecting all parts of the vascular system except those of the heart and brain. Cardiothoracic surgeons and interventional cardiologists manage disease of vessels of the heart. Neurosurgeons and interventional neuroradiologists manage surgical disease of the vessels in the brain (e.g., intracranial aneurysms).
Vascular surgery encompasses surgery of the aorta, carotid arteries, and lower extremities, including the iliac, femoral, and tibial arteries. Vascular surgery also involves surgery of veins, for conditions such as May–Thurner syndrome and for varicose veins. In some regions, vascular surgery also includes dialysis access surgery and transplant surgery.
