Liver Transplant in Budd-Chiari Syndrome: A Single-center Experience in Saudi Arabia

摘要

Objectives: If they do not respond to other treatments, patients with Budd-Chiari syndrome are potential candidates for a liver transplant. Timing for transplant is controversial; however, before other systems deteriorate, early intervention in relatively stable patient may improve the outcome and survival of these patients. Materials and Methods: Six patients (2 women and 4 men) had Budd-Chiari syndrome (1.2%) among 475 patients who had undergone a liver transplant at our center between 2001 and 2012. Imaging modalities including duplex ultrasound, abdominal computed tomography angiography, and hematologic evaluation were part of our routine diagnostic work-up. Although we perform mostly living-donor liver transplants, these patients received a liver transplant from a deceased donor, because there was not enough evidence to justify a living-donor liver transplant. We thought that not replacing the caval vein might negatively influence the outcome. Postoperatively, these recipients were started on a heparin infusion and triple therapy immunosuppression; only then was warfarin introduced as long-term anticoagulant. Results: Two patients died, 1 from uncontrollable bleeding and disseminated intravascular coagulopathy, and the other died in the intensive care unit after 5 months because of multiorgan failure and sepsis. One patient had portal vein thrombosis 9 months after the liver transplant; the other patient needed a liver retransplant after 5 years owing to liver failure, secondary to chronic rejection. Graft survival rate was 75%, and patient survival rate was 66.6%. Conclusions: This is the first article from Saudi Arabia to describe the outcome of a liver transplant in this subgroup of patients with Budd-Chiari syndrome. Treatment of Budd-Chiari syndrome follows a therapeutic algorithm that should start with anticoagulation and may end up with liver transplant; however, it should be considered early if other treatments fail.
