 Alwall also was arguably the inventor of the arteriovenous shunt for dialysis.He reported this first in 1948, where he used such an arteriovenous shunt in rabbits.Subsequently, he used such shunts, made of glass, as well as his canister-enclosed dialyzer, to treat 1,500 people in kidney failure between 1946 and 1960, as reported to the First International Congress of Nephrology held in Evian in September 1960.
