Interesting new study -

"For vascular grafts, the procedure succeeds in restoring the flow of blood, but it leads to a problem: blood clotting.

To improve the results of vascular grafts and lessen the need for blood-thinning meds, scientists from the ITMO University in St. Petersburg, have devised a new type of artificial blood vessel coating that prevents the coagulation of blood known as thrombosis."

Blood clotting is a common result of vascular grafts. A team of Russian researchers have now devised a vascular graft coating that dissolves blood clots, while still allowing vascular grafts to emit vascular medication into the bloodstream.
