Abstract
Objective: Cardiac catheterization is one of the basic procedures applied in the diagnosis and treatment of
cardiovascular diseases. Development of thrombosis is a serious complication of catheterization. In this study, the
frequency and the factors affecting the development of arterial thrombosis were prospectively evaluated in neonates
who were subjected to diagnostic or interventional cardiac catheterization. Methods: Twenty newborns that received femoral artery catheterization within 6-month period were enrolled in this
study. Blood samples were taken for complete blood count, prothrombin, activated partial thromboplastin time, INR
ratio and mutations of factorV Leiden, prothrombin 20210A, methylenetetrahydrofolate reductase C667T and A1298
before the procedure. 100 U/kg bolus of heparin was infused during catheterization. 28 U/kg/hour infusion of
heparin was given to the patients with clinically suspected thrombosis during first few hours after catheterization.
Doppler ultrasonography was performed in all patients within 6 hours after catheterization.
Results: The gestational age of patients ranged from 31 to 40 weeks (median 39). Mean birth weight was 2996 ± 589
(1880-4000 gr). Arterial thrombosis was detected in 10 patients by Doppler USG. On development of arterial
thrombosis, patient age, gender, diagnosis, treatments, platelet count, hemoglobin, prothrombin and activated partial
thromboplastin time values, FactorV Leiden, prothrombin 20210A, methylenetetrahydrofolate reductase C667T and
A1298 mutations were found as not impacting (p>0.05). Those who were found to have thrombosis in Doppler
ultrasonography had lower INR levels compared to others (p= 0.023)
