Summary

This study details a new microsurgical technique for vascularized thymus transplantation in rats, connecting it to the heart and abdominal vessels. The method successfully preserved thymus tissue and its blood supply for fifteen days post-operation.

Area of Science:

  • Surgical innovation
  • Transplantation biology
  • Vascular surgery

Background:

  • Thymus transplantation is crucial for immune reconstitution.
  • Vascularized grafts improve graft survival and function.
  • Microsurgical techniques enable complex vascular anastomoses.

Purpose of the Study:

  • To establish a microsurgical method for vascularized thymus transplantation in continuity with the heart.
  • To assess the viability and vascularization of the thymus-heart graft in a rat model.

Main Methods:

  • Development of a microsurgical technique for thymus-heart graft preparation.
  • Anastomosis of the graft's vascular pedicle to the recipient's abdominal vessels in Wistar rats.
  • Histological examination and microvascular bed assessment up to 15 days post-transplantation.

Main Results:

  • Successful establishment of a vascularized thymus-heart graft.
  • The graft demonstrated well-preserved lymphatic tissue.
  • Adequate blood supply to the graft was confirmed via microvascular bed investigation.

Conclusions:

  • The described microsurgical approach is effective for vascularized thymus transplantation in rats.
  • This technique ensures graft viability through continuous blood supply.
  • The findings support the potential of this method for future immunological studies.
