    Background: Approximately 10–20 % of individuals develop a recrudescent or persistent fever after intravenous immunoglobulin (IVIG) infusion for the initial treatment of Kawasaki disease. The aim of this study was to evaluate the efficacy and safety of the initial IVIG treatment of Kawasaki disease based on duration of infusion. Methods: This retrospective, single-center study included 53 patients with Kawasaki disease who were initially treated with 2 g/kg of IVIG by means of a single infusion from June 2018 to August 2019. We classified patients into two groups based on the duration of the infusion: the 12-h group and the 24-h group. We compared the treatment response of the primary IVIG and its adverse events using the Mann-Whitney U test and Fisher's exact or Chi-square tests. Results: There were no significant differences in the response to initial IVIG treatment between the two groups. The duration from treatment onset to defervescence was shorter in the 12-h group than the 24-h group (7 h vs. 12 h, respectively, p = 0.07); however, this was not significant. There were no significant between-group differences regarding adverse events. Conclusion: We concluded that the initial 12-h IVIG treatment was comparable to the 24-h treatment in terms of efficacy and safety. This will enable physicians to feel confident about pursuing a shorter course of treatment with similar results as conventional treatment and decide on administering additional therapy to their patients.

    Long-term complications after the Fontan procedure are important concerns for patients with pediatric and adult congenital heart disease. Although thrombocytopenia due to portal hypertension and hypersplenism is a well-known complication of the Fontan circulation, few studies have reported on its management. Herein we describe a young adult Fontan patient with thrombocytopenia and a splenic artery aneurysm caused by conduit stenosis. The patient required conduit replacement due to high venous pressure. We performed partial splenic artery embolization (PSE) and embolization of the aneurysm preoperatively to reduce the risk of bleeding, resulting in successful subsequent cardiac surgery. Preoperative evaluation of the splenic artery aneurysm was informative, and PSE was a safe and effective treatment option for thrombocytopenia to avoid bleeding during open-heart surgery in this patient.
