A new medical method may help vascular disease

Friday, 15 June 2012
Researchers at the Sahlgrenska University Hospital in Göteborg have managed to implant a blood vessel made from a patient’s own stem cells in a ten year old, sick girl. One year after surgery she now is doing pretty fine making the researchers to hope that this could be a method to assist patients who need bypass surgery.

The process involves approach, in making the vein perform better  took three to four weeks, according to Michael Olausson, a professor at the Transplantation Center at the hospital. The vein for the girl was obtained from a donation from a deceased person, reports radio Sweden.

“Then we have removed all cells and all the genetic material, and after that we have brought stem cells from the patient who will receive the blood vessel and then grow this vessel out again,” says Michael Olausson, Professor and Director of the Transplant Center at the Sahlgrenska University Hospital in Gothenburg to radio Sweden.

At the moment, Michael Olausson and his team believe that the approach could be of great help to many people with plug formation in their blood vessels and that they need to undergo a so-called "bypass surgery".

Asked how important is it that the patient's own stem cells are included in the vein? Michael Olausson replied that it has to do with the immune system recognizing the tissue as its own and thus will not reject it. For him and the patient, it's a big advantage. All the medications that are normally given to avoid the body rejecting the new cell is very powerful and can cause side effects, so it is desirable to avoid them.

He adds that this new method is also very important so that “we’ll be able to solve problem around such things as hearts or kidneys in the future. The next big step for us is probably a work around to get arteries to function well. This opens the door and then maybe, be able to produce whole organs,” says Michael Olausson.
