Kurzbeschreibung/Zielsetzung
Thromboembolism (TE) and Fontan-associated liver disease (FALD) are common and lead to significant morbidity in Fontan circulations. Risk factors for TE and the potential link between TE and FALD are not well understood. The objective of this study was to evaluate the association between TE and the severity of FALD based on radiologic liver stiffness. Using a retrospective cohort study design, 85 Fontan patients (aged 27.7 ± 8.2 years) who had liver stiffness measurement were included. Multivariable logistic regression was used to determine independent associations with TE. Sixteen patients (19%) had a history of TE after the Fontan procedure at a mean age of 21.4 ± 15.0 years. Patients with TE were significantly older at the time of the last evaluation (33.8 ± 11.7 vs. 26.3 ± 6.5 years, = 0.03). Liver stiffness by MRI and ultrasound was higher in the TE group (5.1 ± 1.4 vs. 4.3 ± 1.2 kPa, = 0.04 and 2.8 ± 0.4 vs. 2.4 ± 0.5 m/s, = 0.04, respectively). On multivariable analysis, higher liver stiffness (odds ratio (OR): 2.12, = 0.03) and older age (OR: 1.11, = 0.03) were associated with TE. This study found an association between TE, age, and radiologic liver stiffness.
