A breakthrough in vein implantation techniques

On June 14, doctors at the University of Gothenburg in Sweden reported that they had successfully implanted successfully from the patient's own stem cells to a 10-year-old girl.

The first success in this type of venous implant technique is a breakthrough, giving hope to patients whose veins are not strong enough to withstand dialysis or artificial heart replacement surgery.

Doctors took a 9cm long vein from a patient who offered to donate before dying, taking all living cells out of this vein. They then transplanted stem cells from the bone marrow of a girl, diagnosed with a vein occlusion that transports blood to release toxins in the liver - a disease with high risk of death.

After 2 weeks of nourishing the vein in the laboratory, doctors began to transplant this vein to patients, using artificial vein techniques.

Although there were initially some movement disorders in the legs, the doctors confirmed that the patient had no signs of complications and that the blood flow to the liver to remove the poison was immediately restored.

Furthermore, veins are fed from the patient's own stem cells so girls do not need to use drugs to avoid venous obstruction, as is often the case for patients with "foreign" venous implants .

Currently the girl is walking 3 km and can participate in some light sports activities.

The authors of the study said that new vein grafting techniques can greatly improve the quality of life of patients. However, due to the high cost and time of prolonged surgery, it is difficult to become popular immediately.

Doctors at the University of Gothenburg are studying to be able to apply this technique extensively. The results of their surgery were being downloaded in the British medical journal The Lancet.
