[New method of thymus transplantation]

A surgical procedure for correction of T-system immunity deficiency in primary immunodeficient states and malignant neoplasms in children is described. To ensure a high physiological activity of the transplant, to prevent anti-recipient reaction and to maintain laminar blood flow in the transplant, thymus glands were obtained from fetuses and separated from breast bone. Blood channel reconstruction was performed before the gland transplant was washed and connected to the patient's blood flow. Thymus transplantation was carried out in 25 cases and neither acute rejection nor anti-recipient reaction were observed. Immune response indices returned to normal within 6-7 months.
