Vascular surgery is a surgical subspecialty in which diseases of the vascular system, or arteries, veins and lymphatic circulation, are man-aged by medical therapy, minimally-invasive catheter procedures, and surgical reconstruc-tion. Vascular disease is caused by inflammation and weakness of the veins and arteries; and by the build up of fatty deposits in the blood vessels Often life-saving procedures are unexpectedly needed during a surgery. Surgery is performed to clear blockages in the blood system to pre-vent strokes and aneurysms; usually due to ageing and degeneration. Other reasons for surgery include injury and trauma, conditions like cancer, and diabetes. Angioplasty and stents placement are two ways to open blocked peripheral arteries.
