Features of the Restoration of Arterial Circulation in Liver Transplantation
Objectives. Violations of tissue blood supply remain one of the most serious complications after
liver transplantation.
Design. To improve the surgical technique of performing reconstructive interventions on the
arteries of the donor and the recipient in order to reduce the frequency of its thrombosis after liver
transplantation.
We studied 25 donors, 20 men and 5 women, the mean age was 56± 4 years, eighteen of them
had left aberrant supplementary artery, which in fifteen departed from the left gastric artery and in
three from the aorta above the ventricular stem. Seventeen had the right aberrant artery moving
away from the upper mesenteric artery. Twenty recipients with liver cirrhosis (eleven with primary
biliary cirrhosis, five with primary sclerosing cholangitis, five with viral etiology C cirrhosis, and three
of the lower cirrhosis-cirrhosis disseminated within the Milan criteria. All recipients had standard
anatomical branching of the arteries of the liver. The average age was 50±6.
All recipients had standard anatomical branching of the liver arteries. Patients underwent liver
transplantation with new methods of reconstructive interventions on the donor and recipient
arteries.
The developed technique provides the shortest pathway of the recipient's arterial blood to the
liver transplant, through the superior mesenteric artery provides an alternative source of arterial
blood supply from the aorta in which this transplant additionally needs.
Presented method of blood circulation restoration at liver transplantation at abnormal structure
of arterial channel of the liver transplant is performed inside the recipient's abdominal cavity. At first,
blood flow is restored along the reconstructed common hepatic artery, after the right or left aberrant
arteries liver transplant. Such technique provides the shortest route of the recipient's arterial blood
to the liver transplant, through the upper mesenteric artery provides an alternative source of arterial
blood supply from the aorta for which the transplant is additionally needed. This new method of
blood circulation restoration provides an opportunity to avoid the formation of "kinking" syndrome, in
the occurrence of which the blood vessels are lengthened, the angulation and location of the blood
vessel in relation to the grafts and other abdominal organs. This reduces the risk of thrombosis of
the arteries of the transplanted liver
