What do cardiovascular surgeons practice on to learn how to sew arteries and veins together?

Hi there.

Before cardiovascular surgeons get to sew arteries in live hearts, they usually had some forms of training either in animals, or minor cases (like creation of dialysis accesses like areriovenous fistulas, etc. In fact, for those surgeons who dont do coronary bypass surgery on a daily or regular basis, these type of minor surgery maintains his basic surgical skills.

I invented a few years back, an office set-up training model for vascular anastomosis. This was made for the purpose of honing the anastomosis skills of training residents.

suprising or not they practice on veins and arteries. There are cadavers (bodies) to practice on and then they practice on live bodies in theatres with qualified and experienced surgeons overseeing their work. So you are perfectly safe

they have practised on cadavers both human and animal.

but eventually they also have to practise on living patients, it is the nature of the profession that they do so. Ordinarily when a surgeon is new at what he is doing, he will have an experienced surgeon who can step in at need.

Cadavers both human and animal.

cadavers are donated to medical schools for dissecting and practice
