Transplantation Orthotopic

Orthotopic transplantation is a method of organ and tissue transplantation in which a donor organ or tissue is placed in the same place where it was previously. This method is the most effective and safe compared to other transplantation methods.

The essence of orthotopic transplantation is that the donor tissue or organ is placed in a place corresponding to its natural location in the body. For example, in a kidney transplant, the donor kidney is placed in an area where it would be located in a healthy body. In a liver transplant, the donor liver is placed in the location of the liver's natural location in the body.

One of the advantages of orthotopic transplantation is that it avoids scarring and other complications associated with transplantation. In addition, orthotopic transplants generally have higher patient survival rates than other transplant methods.

*Orthotomy transplantation* is a surgical intervention involving the transplantation of a fragment or organ dissected along the anatomical boundaries, possibly supplemented by amputation. The operation is performed provided that the topography of the vessels and nerve pathways of the graft coincides with the patient’s tissues. The purpose of the transplant is to restore lost functions without disrupting blood circulation, innervation and creating an exoprosthesis. The transplants were called “orthotopic”, and the surgical methods were called “orthotopectomy”. It should be taken into account that many operations are, in fact, “orthotopic”, for example, gastrectomy, an arm without a shoulder joint after injury, etc. Currently, transplantation as a replacement surgical intervention has only limited indications as a method of choice. For example, replacing a dying limb fragment (long-term result of tissue infarction: complicated by vascular thrombosis).
