Abstract

Orthotopic liver transplantation with preservation of the retrohepatic inferior vena cava (IVC) using the so-called piggyback technique (MBT) has a number of priorities over the classical technique. Since 2006, our Belghiti modified piggyback technique (MPBT) has been used in our center as a normal procedure for a liver transplantation program and has been performed 490 times by December 2018. Among them, in 6 recipients in the immediate postoperative period (12- 48 hours), occlusion of the own veins of the liver graft was noted. In all 6 observations, whole liver was used, obtained from the donor after ascertaining brain death. The age of these recipients was 32 ± 12 years, the age of donors was 48 ± 10 years. Percutaneous stenting was not used to correct the venous outflow. Re-transplantation due to the absence of a donor organ was not performed. The best way to treat occlusion of blood outflow from the veins of a liver transplant is to prevent the very cause of its occurrence. The length of the upper vena cava of the graft must be short enough to prevent its fracture and redundancy, and the length of the anastomosis must provide a good venous outflow and be at least 6 cm. segments of the transplanted liver. The results of our study led to the conclusion that early diagnosis of occlusion of the own veins of a liver transplant, based on clinical signs and ultrasound diagnostics, allows detecting pathology in time, reducing ischemic damage to the transplanted organ increases the possibilities of its recovery.
