Objectives: Adequate venous outflow is one of the most important factors responsible for optimal graft function in liver transplantation. Thrombosis of the inferior vena cava in cases of Budd-Chiari syndrome poses a major challenge to a transplant surgeon in establishing proper graft outflow. In deceased donor liver transplant, this problem can be dealt with relative ease as the liver graft includes donor inferior vena cava. However, this is not the case in living donor liver transplant. We present our findings of living donor liver transplant for Budd-Chiari syndrome and discuss techniques that have helped overcome this unique problem without the need for complete inferior vena cava replacement.
Materials and methods: Our retrospective analysis included living donor liver transplant recipients from November 2006 to March 2020 at our center and selected patients who underwent this transplant for Budd-Chiari syndrome. We studied the extent and severity of inferior vena cava involvement in these cases. We developed a classification that not only helped to stratify patterns of venacaval disease but also helped to plan the surgical technique. The role of interventional radiology combined with surgery in management of extensive inferior vena cava stenosis was studied.
Results: Among 2952 cases of liver transplant in our unit from November 2006 to March 2020, 36 patients had Budd-Chiari syndrome; 21 had significant level of inferior vena cava thrombosis, which was managed with inferior vena cava thrombectomy with either patchplasty (n = 20) or segmental replacement (n = 1). None of our patients showed recurrence of primary disease during the median follow-up of 36 months (range, 8-158 mo).
Conclusions: Establishment of adequate venous ouflow in thrombosed inferior vena cava is possible with proper planning of surgical technique and timely involvement of interventional radiology-guided interventions in patients with Budd-Chiari syndrome.
