Luigi Porta

Luigi Porta (4 January 1800 – 10 September 1875) was an Italian surgeon and professor at the University of Pavia.

He pioneered the field of vascular surgery and noted collateral circulation following ligation of arteries.

He received another degree from Pavia in 1826 and became a professor of clinical surgery from 1832, succeeding his teacher, Antonio Scarpa.

From 1835 he conducted experiments on animals, examining pathologies induced by ligation of blood vessels.

In 1847 he published on his experiments with anaesthesia where chloroform gas held in the bladder of a pig was delivered into the mouth of a patient whose nostrils were closed.
