Abstract

METHOD pancreas transplant, vklyuchakhtsy fence kolshleksa pancreatic of duodenal or pancreatic segment from a donor with a portion of the aorta and the portal vein or proximal and distal portions of the splenic artery and vein and its posleduyusch5p6 transplant recipient / ogli-cha.yuschi .ys in that To exclude ischemic damage to the graft, temporary external shunts are used to connect the splenic artery and the vein of the recipient, respectively, with the distal end of the aortic segment and the superior mesenteric vein. donor or. The femoral artery and vein of the recipient, respectively, with the distal portions of the splenic arteries and veins of the donor, and after restoring the vascular connections of the graft with the recipient, temporary shunts are removed.

Description

The invention relates to surgery / specifically transplantology, and can be used for transplantation of the pancreas:

There is a known method for pancreas transplantation, in which the pancreas is mobilized from the donor, the vessels supplying it are isolated, the pancreas is removed from the donor, and preserved, it is stored outside the body; then the pancreas is placed in the recipient’s body, the vessels of the donor’s gland are connected with the vessels of the recipient, and blood circulation is restored in the transplanted organ [1]. ' fifteen

However, the cold preservation of the pancreas leads to the destruction of parts of the organ.

There is also a known method for pancreas transplantation, consisting of preserving through blood flow in the transplantation area by collecting the pancreas from the donor with portions of the splenic artery and vein, followed by perfusion with a cooled 25 solution and transplantation to the recipient, the proximal and distal ends of the splenic vessels being connected. with the vessels of the recipient's with the formation of a vascular insert [2]. 3θ

The disadvantage of this method is ischemic damage to the graft.

The aim of the invention is the elimination of ischemic damage to trans-35 plantate.

This goal is achieved by the fact that according to the method of transplantation of the pancreas, which includes taking a pancreatic-duodenal complex or segment of the pancreas from a donor with a section of the aorta and portal vein or with the proximal and distal sections of the splenic artery and vein and the subsequent.

transplantation to its recipient, use temporary external shunts connecting the splenic artery and vein of the recipient, respectively, with the distal end of the aortic segment and the superior mesenteric vein of the donor, or femoral artery and vein of the recipient, respectively, with the distal portions of the splenic artery and vein of the donor and after restoration of transplant vascular connections with the recipient. 55 temporary shunts are removed.

The method is as follows.

After mobilization of the pancreas and duodenum and separation of the vessels supplying them together with the aorta and portal vein from the donor, removal of the spleen from the recipient and isolation of the aorta and the inferior vena cava at the site of their bifurcation, the operating tables are shifted and the splenic artery and vein are connected by shunts the recipient, respectively, with the aorta distal to the site of discharge of the superior mesenteric artery and the superior mesenteric vein of the donor. The aorta is squeezed and crossed at the donor proximal to the place of celiac artery discharge and the portal vein distal to the confluence of the splenic vein, and at the same time they include blood flow in the shunts, providing blood supply to the donor organ complex from the recipient's body. The graft is removed from the donor, the operating tables are pushed apart and the organocomplex is placed in the recipient's body. Connect the aorta and portal vein of the donor, respectively, with the aorta and the inferior vena cava. Temporary shunts are removed. When transplanting a pancreatic segment, the recipient’s femoral artery and vein are connected with shunts to the distal ends of the splenic artery and vein of the donor, after which the graft is removed from the donor, placed in the recipient’s body, and the proximal ends of the splenic artery and vein are connected with the internal iliac artery and veins the recipient's vein, and temporary shunts are removed.

Using the proposed method allows for continuous ₍ <continuous blood supply to the donor pancreas segment at the stages of transplantation, and also eliminates the need to protect the organ from ischemic damage after removing it from the donor. Using the method minimizes the likelihood of complications associated with the lack of blood supply transplant and its cold preservation · ".

♦

The proposed method can be used to carry out ortho and heterotopic transplantation of a segment of the pancreas or pancreato-duodenal complex.
