June 15 – The first vascular surgery in history is performed by a Dr. Hallowell at Newcastle upon Tyne in England, who uses suture repair rather than a tying off with a ligature to repair an aneurysm on a patient's brachial artery.[4][5] The new procedure of reconstructing a damaged artery replaces the practice of ligation that had risked the amputation of a limb or organ failure.[6]
