From Michael Dashwood
The article on using helical grafts for bypass surgery, rather than straight ones, was very interesting (11 June, p 28). There is also a technique using vein grafts that has extremely promising follow-up results. This “no touch” method avoids exposing the vein to the surgical trauma that it suffers in conventional vein harvesting, aiming to remove it with minimal surgical damage.
Presumably the manufactured grafts mentioned in the report are quite expensive. It might be possible to improve the function of a graft merely by improving methods of surgical preparation.
