Disseminated Intravascular Coagulation as a Risk Factor for Clinical Outcome After Liver Transplantation in Pediatric Patients With Kasai Portoenterostomy Failure

Abstract

Background: Disseminated intravascular coagulation (DIC) is a serious complication in critically ill pediatric patients. This study aimed to evaluate the association between pretransplant DIC and perioperative clinical outcomes of liver transplantation (LT) in pediatric patients with Kasai portoenterostomy (KPE) failure.

Methods: We enrolled pediatric patients who received LT after KPE failure between January 2005 and April 2021. We retrospectively reviewed the electronic medical records of included patients and evaluated the presence of DIC using the International Society on Thrombosis and Hemostasis (ISTH) criteria and association with perioperative clinical outcome.

Results: The study included 106 patients. Their median age and body weight at the time of pediatric intensive care unit (PICU) admission were 28.7 months and 9.25 kg, respectively. Of these patients, 23 had undergone pretransplant DIC (22%). Patients with pretransplant DIC required significantly more blood transfusions during operation. They had significantly higher serum lactate levels, pediatric end-stage liver disease scores, pediatric risk for mortality III (PRISM III) scores, longer durations of mechanical ventilator support, and longer PICU stays (all P < .05).

Conclusions: The presence of pretransplant DIC in pediatric patients requiring LT after KPE failure was associated with poor clinical outcomes, which required more intensive and meticulous supportive management in the perioperative period of LT. DIC would be a promising prognostic factor in these patients.
