As per a new finding by the U.S. researchers, engineered vascular grafts could be used instead of synthetic veins for heart bypass operations and kidney dialysis rectification.

The researchers have triumphed in growing human veins, which reported lesser clotting, infections and obstructions, than when the man-made veins were used.

A combined team of scientists from the Duke University, East Carolina University and Yale University initiated the present study, which can be hailed as a revolution in the medical industry.

Prof. Jeremy Pearson, who is an Associate Medical Director at the British Heart Foundation said, “Not everyone is well enough to have a vein taken from another part of their body during heart surgery, so using synthetic veins can become an important part of a patient's treatment.”

But, he also said that even synthetic veins were considered unsuitable at times and bioengineered grafts helped yield better results for the patients.

Important study
More than 7,50,000 Brits suffer from heart failures in present times and on an average 400,000 bypass surgeries are performed annually in the U.S.

Dr. Alan Kypson of the Brody School of Medicine at East Carolina University stated, “Currently, grafting using the patient's own veins remains the gold standard. But, harvesting a vein from the patient's leg can lead to complications, and for patients who don't have suitable veins, the bio-engineered veins could serve as an important new way to provide a coronary bypass."

The researchers would undertake human trials soon and only then can the exact success of these laboratory-grown veins over synthetic, man-made veins be measured.

Also, as the veins are sterile, there are lesser chances of the immune system rejecting it and also they can be grown in any size, depending on the need.

These veins would benefit kidney patients, who have to undergo dialysis regularly and so a faster mechanism would be provided to them.

Findings of the present study have been detailed in the journal of Science Translational Medicine.
