Stanford researchers invent sutureless method for joining blood vessels

Reconnecting severed blood vessels is mostly done the same way today — with sutures — as it was 100 years ago, when the French surgeon Alexis Carrel won a Nobel Prize for advancing the technique. Now, a team of researchers at the Stanford University School of Medicine has developed a sutureless method that appears to be a faster, safer and easier alternative.

In animal studies, a team led by Stanford microsurgeon Geoffrey Gurtner, MD, used a poloxamer gel and bioadhesive rather than a needle and thread to join together blood vessels, a procedure called vascular anastomosis. Results of the research were published online 28 August in Nature Medicine. Lead authors of the study were postdoctoral scholar Edward Chang, MD, and surgery resident Michael Galvez, MD — via redwolf.newsvine.com
