BACKGROUND As the survival of children with cardiac disease increases, chronic complications of deep venous thrombosis from cardiac catheterization, particularly post-thrombotic syndrome, may be important to monitor for and treat, if needed. We aimed to determine the prevalence of this syndrome in children who underwent cardiac catheterization. PROCEDURE We conducted a cross-sectional study of children <18 years old at least 1 year from first catheterization through the femoral vein. We used the Manco-Johnson instrument, the only tool validated in children, to diagnose post-thrombotic syndrome. We defined the syndrome as a score ≥1. It was considered physically and functionally significant if the score was ≥1 in both physical and functional domains of the instrument. We also conducted ultrasonography to assess for thrombosis and valvular insufficiency. RESULTS We enrolled 62 children with a median age of 4 months during catheterization and a median of 5.4 years since catheterization. A total of 40 children had post-thrombotic syndrome (prevalence: 64.5%; 95% confidence interval: 51.3%–76.3%), the majority of which were mild. Presence of cyanotic congenital heart disease, total number of catheterizations, use of antithrombotic agents at any time after the first catheterization, age at first catheterization, or time since first catheterization was not associated with the syndrome. A total of 7 children (prevalence: 11.3%; 95% confidence interval: 3.2%–19.4%) had physically and functionally significant syndrome. None of the children had abnormalities on ultrasonography at the time of enrollment. CONCLUSIONS Post-thrombotic syndrome is a common complication after cardiac catheterization. Manifestations are usually mild and unlikely to require treatment.
Cyanosis in a newborn is commonly due to intracardiac shunts or duct-dependent lesions. Systemic venous anomalies are uncommon and sinus venous atrial septal defects do not usually present with cyanosis. We report the case of a 4-month-old female with persistent hypoxemia due to a right superior vena cava overriding a superior sinus venous atrial septal defect resulting in a right to left shunt.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
