Coronary bypass: new insights on ‘no-touch’ vein harvesting

For coronary artery bypass grafting (CABG), a ‘no-touch’ technique to harvest the saphenous vein graft has been considered superior to the conventional approach. Surprisingly, a new study comes…

Rare blood clotting in brain after Covid-19 vaccination: study gives new insights

A new study of patients with cerebral venous thrombosis (CVT) following Covid-19 vaccination provides a clearer guide for clinicians trying to diagnose and treat patients. The research, led by University College London (UCL) and UCL Health and published in The Lancet, is the most detailed account of the characteristics of CVT, when it is caused by the novel condition vaccine-induced immune…

Synthetic tissue with growing blood vessels developed

Using lab-created tissue to heal or replace damaged organs is one of the great visions for the future of medicine. Synthetic materials could be suitable as scaffolding for tissue because, unlike natural tissues, they remain stable in the organism long enough for the body to form new natural structures. A fundamental requirement for functional tissue is that blood vessels must be able to grow in…

Magnetic stimulation boosts blood vessel formation

Magnetic fields can be used to stimulate blood vessel growth, according to a new study. The findings, published in the journal Science and Technology of Advanced Materials by researchers at the Técnico Lisboa and NOVA School of Science and Technology in Portugal, could lead to new treatments for cancers and help regenerate tissues that have lost their blood supply.
