Award-winning research could save lives, says doctor behind discovery

This discovery was published in his doctoral thesis. Subvascular Aortic Aspects in Examination Setup (pdf) It led to new recommendations for screening of the arteries in both Sweden and Europe. Knut Thorbjørnsen's research has also been awarded numerous scientific prizes.

“It is great to see that our work is influencing how this disease is managed and that we are contributing to better care for people with varicose veins across Europe,” says Knut Thorbjørnsen.

Knut Thorbjørnsen is a senior physician and vascular surgeon at Gävle Hospital. He followed 1,020 men in Gävleborg, Dalarna, Sörmland and Uppsala. The men had a small enlargement of their carotid artery, called a subaortic aneurysm, and for the purposes of the study they had to undergo follow-up examinations for up to 15 years. The study shows that the majority, 90%, develop an aneurysm over time, and a third of them develop a life-threatening aneurysm.

“Our research shows that this group cannot be ignored as it was previously. A significant proportion of these men eventually develop abdominal aneurysms that require surgery. If these men are declared healthy at age 65, they risk dying from aneurysm rupture later in life,” says Knut Thorbjørnsen, continuing:

– As life expectancy continues to increase, follow-up of this subgroup has become increasingly important. Therefore, continued screening is recommended for men with mild pulsatile artery dilatation.

As a result of Knut Thorbjørnsen's discovery, Swedish and European guidelines for arterial screening were strengthened and clarified. His research has also won numerous scientific awards and attracted international attention.

“It feels great to be noticed. It’s gratifying to see that our work is actually making a difference,” says Knut Thorbjornsson.

The research on varicose veins was carried out thanks to financial support from the Centre for Research and Development (CFUG) in the Gävleborg region. An important research partner was the research group Uppsala Vascular Research Group.
